Heterogeneous GridLayout

Heterogeneous GridLayout - android

I am trying to implement the layout below:
I guess GridLayout is suitable for my needs but after 2 hours of struggle I couldn't create even a similar layout.. The layout is resizing itself wrongly, it exceeds the screen of the phone and it also does not span the specified rows and columns.
Here I selected a button so you can see how it exceeds the boundaries:
and here is the associated xml code: https://gist.github.com/2834492
I have reached a similar layout with nested linearlayouts but it's not possible to properly resize it for different screen sizes.
UPDATE - approximate LinearLayout implementation:
The XML code: https://gist.github.com/cdoger/2835887
However, the problem is it does not resize itself properly here some screenshots with different screen configurations:
TLDR: Can someone show me a heterogeneous layout implementation with GridLayout like in the first picture?

The issue you are facing is due to inappropriate use of the GridLayout. The GridLayout is made to show its children in a grid and you are trying to override that without extending the GridLayout. While what you want may be accomplished in code (utilizing numcolumns and columnsize), it will not be useful for multiple screen sizes without a heck of a lot of code.
The only adequate solution that won't require a ton of hacking is judicious use of both LinearLayout and RelativeLayout. LinearLayout should not be used exclusively as it is made to drop items in a line (horizontally or vertically only). This becomes especially apparent when you try and do the bottom four buttons. While the buttons above may be done with LinearLayout with very little effort, RelativeLayout is what you need for the bottom four buttons.
Note:
RelativeLayout can be a little bit tricksy for those with little experience using them. Some pitfalls include: children overlapping, children moving off the screen, height and width rendering improperly applied. If you would like an example, let me know and I will edit my answer.
Final Note:
I'm all for utilizing the current framework objects in unique ways, and genuinely prefer to provide the requested solution. The solution, however, is not viable given the constraints of the question.
(Revision) Solution 1
After some careful thought last night, this may be accomplished with a pure LinearLayout. While I do not like this solution, it should be multi-screen friendly and requires no tooling around from me. Caution should be used with too many LinearLayouts, as according to Google's developers, it can result in slow loading UIs due to the layout_weight property. A second solution utilizing RelativeLayout will be provided when I return home. Now Tested This provides the desired layout parameters on all screen-sizes and orientations.

Solution 1 Explanation
The key to LinearLayouts is to define your imperatives as separate Layouts and nest the others in them. As you apply constraints to more dimensions, more LinearLayouts must be added to encapsulate the others. For yours, it was crucial to have two more parents in order to maintain the proportion. A great indicator of when you should add another level is when you have to utilize layout_weight using anything other than an integer value. It simply becomes to hard to calculate properly. From there it was relatively simple to break it into columns.
Solution 2 (Failed)
While I was able to achieve desirable results utilizing RelativeLayout and "struts", I could only do so with layouts that were multiples of 2 buttons in height. Such a trick would be awesome as the levels of layout are greatly reduced, so I will work on a pure XML solution and post the answer here if and when I achieve it. In the meantime, the LinearLayout above should suit your needs perfectly.

I read this thread and realised that I wanted a flatter solution than those with linear layout. After some research I ended up making my own layout. It is inspired by a GridLayout but differs a bit.
Please note that if you are going to copy-paste the code you'll need to change package names in some places.
This layout has 4 layout parameters that children use to position themselves.These are layout_left, layout_top, layout_right, layout_bottom. The ICGridLayout itself has two attributes: layout_spacing and columns.
Columns tells the layout how many columns you want it to contain. It will then calculate the size of a cell with the same height as width. Which will be the layouts width/columns.
The spacing is the amount of space you want between each child.
The layout_left|top|right|bottom attributes are the coordinates for each side. The layout does no calculations in order to avoid collision or anything. It just puts the children where they want to be.
If you'd like to have smaller squares you just have to increase the columns attribute.
Keep in mind that this is a quick prototype, I will continue working on it and when I feel that it's ready I'll upload it to Github and put a comment here.
All of my code below should produce the following result:
*****EDIT*****
Added the call to measure for the children, forgot that the first time around.

As many have said, nested linear layouts seem the only way to win here. Some of the solutions have not used the layout parameters in the most flexible manner. Code below seeks to do that, and in a way that's robust with aspect ratio changes. Details are in the comments.

So here is the solution I promised after one year =)
It basically uses the ViewTreeObserver to get the dimensions of the parent layout and create custom views accordingly. Since this code is one year old ViewTreeObserver might not be the best way to get the dimensions dynamically.
You can find the full source code here:
https://github.com/cdoger/Android_layout
I divided the screen into 8 equal widths and 6 equal heights. Here is a snapshot of how I laid out the views:
final RelativeLayout mainLayout = (RelativeLayout) findViewById(R.id.main_layout);
ViewTreeObserver vto = mainLayout.getViewTreeObserver();
vto.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
#Override
public void onGlobalLayout() {
final int oneUnitWidth = mainLayout.getMeasuredWidth() / 8;
final int oneUnitHeight = mainLayout.getMeasuredHeight() / 6;
/**
* 1
***************************************************************/
final RelativeLayout.LayoutParams otelParams = new RelativeLayout.LayoutParams(
oneUnitWidth * 4, oneUnitHeight);
otelParams.addRule(RelativeLayout.ALIGN_PARENT_TOP);
otelParams.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
// otelParams.setMargins(0, 0, 2, 0);
View1.setLayoutParams(otelParams);
/***************************************************************/
/**
* 2
***************************************************************/
final RelativeLayout.LayoutParams otherParams = new RelativeLayout.LayoutParams(
oneUnitWidth * 4, oneUnitHeight);
otherParams.addRule(RelativeLayout.ALIGN_PARENT_TOP);
otherParams.addRule(RelativeLayout.RIGHT_OF, View1.getId());
otherParams.setMargins(2, 0, 0, 0);
View2.setLayoutParams(otherParams);
/***************************************************************/
//... goes on like this

There is no need to inflate three whole FrameLayout just for that.View will do just fine. Also you should not give fixed widths since there is no way to make it work for all screen sizes.

Making Recyclerview Fixed Height and Scrollable

SOLVED CHECK ANSWER BELOW...
So I am trying to create a comments functionality for my Android app and I want to display the comments inside a recyclerview and then have a button and textview below the recyclerview to add comments. I want to have the recyclerview a certain height and make it scrollable if there are lots of comments because I dont want the users to have to scroll down the screen to find the add button.
I couldn't get it to work so I was wondering if anyone else had that issue.
I have all the adapter and everything set up, I am just having trouble with the recyclerview.
Thanks.
I prob was not clear on what I was trying to accomplish. I am trying to create a cardview where it will display all the comments and the ability to add a new comment. The recyclerview will take up approx 80% of the height and then the last 20% is for the edittext and button.
My XML (Scroll to last cardview where the recyclerview is)

The second and first comment are being cut off.

So what my problem was that for some reason, Recyclerview didnt wrap_contents. I did some research (thanks stackoverflow) and found out a lot of people were having this issue and they posted solutions for this issue.
Basically, I had to use a customized linearlayoutmanger to fix the issue.
I will post the solution they posted and links to their questions. thanks for whoever tried to help, I appreciate it.
This is the extra file I needed. And then I had to set my recyclerview to use this layout instead of the default one.
public class MyLinearLayoutManager extends LinearLayoutManager {
public MyLinearLayoutManager(Context context, int orientation, boolean reverseLayout) {
super(context, orientation, reverseLayout);
}
private int[] mMeasuredDimension = new int[2];
#Override
public void onMeasure(RecyclerView.Recycler recycler, RecyclerView.State state,
int widthSpec, int heightSpec) {
final int widthMode = View.MeasureSpec.getMode(widthSpec);
final int heightMode = View.MeasureSpec.getMode(heightSpec);
final int widthSize = View.MeasureSpec.getSize(widthSpec);
final int heightSize = View.MeasureSpec.getSize(heightSpec);
int width = 0;
int height = 0;
for (int i = 0; i < getItemCount(); i++) {
measureScrapChild(recycler, i,
View.MeasureSpec.makeMeasureSpec(i, View.MeasureSpec.UNSPECIFIED),
View.MeasureSpec.makeMeasureSpec(i, View.MeasureSpec.UNSPECIFIED),
mMeasuredDimension);
if (getOrientation() == HORIZONTAL) {
width = width + mMeasuredDimension[0];
if (i == 0) {
height = mMeasuredDimension[1];
}
} else {
height = height + mMeasuredDimension[1];
if (i == 0) {
width = mMeasuredDimension[0];
}
}
}
switch (widthMode) {
case View.MeasureSpec.EXACTLY:
width = widthSize;
case View.MeasureSpec.AT_MOST:
case View.MeasureSpec.UNSPECIFIED:
}
switch (heightMode) {
case View.MeasureSpec.EXACTLY:
height = heightSize;
case View.MeasureSpec.AT_MOST:
case View.MeasureSpec.UNSPECIFIED:
}
setMeasuredDimension(width, height);
}
private void measureScrapChild(RecyclerView.Recycler recycler, int position, int widthSpec,
int heightSpec, int[] measuredDimension) {
View view = recycler.getViewForPosition(position);
if (view != null) {
RecyclerView.LayoutParams p = (RecyclerView.LayoutParams) view.getLayoutParams();
int childWidthSpec = ViewGroup.getChildMeasureSpec(widthSpec,
getPaddingLeft() + getPaddingRight(), p.width);
int childHeightSpec = ViewGroup.getChildMeasureSpec(heightSpec,
getPaddingTop() + getPaddingBottom(), p.height);
view.measure(childWidthSpec, childHeightSpec);
measuredDimension[0] = view.getMeasuredWidth() + p.leftMargin + p.rightMargin;
measuredDimension[1] = view.getMeasuredHeight() + p.bottomMargin + p.topMargin;
recycler.recycleView(view);
}
}
}
After that. Change this:
mProductsRecyclerView.setLayoutManager(new LinearLayoutManager(getApplicationContext()));
To this:
mRecyclerView.setLayoutManager(new MyLinearLayoutManager(getApplicationContext(),1,false));
Three new paramets(Context, int Orientation, boolean reverse);
basically, i put 1 for orientation so it shows vertiacally, and false for revers so it shows up how it is ordered in my List.

Nested Recycler view height doesn't wrap its content
Nested Recycler view height doesn't wrap its content
Thanks once again guys. Hope this helps someone else

Add this code in your activity, will set the height of your recycler view to the 90% of user's screen window.
DisplayMetrics displaymetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
int a = (displaymetrics.heightPixels*90)/100;
recylcerView.getLayoutParams().height =a;
and your comment layout below the your recyclerView
like this
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:layout_alignParentTop="true"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/mudit"
>
<android.support.v7.widget.RecyclerView
android:id="#+id/my_recycler_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:elevation="5dp"
android:scrollbars="vertical" />
</LinearLayout>
<RelativeLayout
android:layout_below="#+id/mudit"
android:id="#+id/rl_commentWrap"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true" >
<EditText
android:id="#+id/editText1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:ems="10" />
<Button
android:id="#+id/plusButton"
style="android:buttonStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:text="Send"
android:textColor="#FFFFFF"
android:translationZ="5dp" />
</RelativeLayout>
</RelativeLayout>

In my situation I had a DialogFragment, in which there are 2 recyclers and 2 horizontal linear layouts with 2 buttons.
Dialog from top to bottom looks like this:
RecyclerView A
Horizontal linear layout X with 2 buttons
RecyclerView B
Horizontal linear layout Y with 2 buttons
On top of that both recyclers size is dynamic.
Recycler A size can change based on user swipes in both recyclers.
Recycler B size can change based on its item click listener.
What I wanted to achieve was to cut the Dialog from top to bottom
and have each of those four views its constant part of the Dialog height.
What worked was to divide it first to 2 separate relative layouts, say lTOP and lBottom. Set lTOP alignParentTop, lBottom alignParentBottom and layout_below lTOP.
Both of them width match_parent, height wrap_content.
Then in each of them create 1 relative (say lINTop) and 1 linear (say lINBottom) layouts. lINTop has recycler, lINBottom has 2 buttons.
Set both lINTop lINBottom width match_parent, height wrap_content.
Set lINTop alignParentTop, lINBottom alignParentBottom and below lINTop.
Set lINTop orientation vertical, lINBottom orientation horizontal.
Set recyclers width match_parent, height wrap_content.
Then i putted this all inside single relative layout with width/height wrap_content and orientation vertical.
Then this inside scrollview with width/height match_parent and orientation vertical.
Then needed a little code magic for setting up recycler in onCreateView:
For Recycler A:
private void setupRecyclerA() {
// use a linear layout manager
RecyclerView.LayoutManager layManUS = new LinearLayoutManager(setupActivity().get());
recyclerA.setLayoutManager(layManUS);
recyclerA.addItemDecoration(new DividerItemDecoration(
setupActivity().get(), LinearLayoutManager.VERTICAL));
recyclerA.setNestedScrollingEnabled(true);
// use this setting to improve performance if you know that changes
// in content do not change the layout size of the RecyclerView
recyclerA.setHasFixedSize(true);
}
For Recycler B:
private void setupRecyclerB() {
// use a linear layout manager
RecyclerView.LayoutManager layManUS = new LinearLayoutManager(setupActivity().get());
recyclerB.setLayoutManager(layManUS);
recyclerB.addItemDecoration(new DividerItemDecoration(
setupActivity().get(), LinearLayoutManager.VERTICAL));
recyclerB.setNestedScrollingEnabled(true);
// set fixed height
DisplayMetrics displaymetrics = new DisplayMetrics();
setupActivity().get().getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
// set height to 30 percent of dialog
int a = (displaymetrics.heightPixels*30)/100;
recyclerB.getLayoutParams().height =a;
// use this setting to improve performance if you know that changes
// in content do not change the layout size of the RecyclerView
recyclerB.setHasFixedSize(true);
}
I didnt invented it, I just combined solutions from many different Stack Overflow questions which I dont even remember now, sorry and thanks to the Creators.

I had a similar problem and solved it with RelativeLayout. I have this layout:
I wanted the top and bottom cardview to stay in place while scrolling the central recyclerView. Tried with LinearLayout and ConstraintLayout but didn't work, the bottom CardView only was shown when I scrolled to the end of the recycler.
This is my code, notice the layout_above, layout_below, and layout_alignParentBottom attributes:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/grisMasOscuro">
<androidx.cardview.widget.CardView
android:id="#+id/cv1"
android:layout_width="match_parent"
android:layout_height="50dp" >
<!-- cardview content -->
</androidx.cardview.widget.CardView>
<androidx.cardview.widget.CardView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#id/cv3"
android:layout_below="#id/cv1">
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/myRecyclerView"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</androidx.cardview.widget.CardView>
<androidx.cardview.widget.CardView
android:id="#+id/cv3"
android:layout_width="match_parent"
android:layout_height="100dp"
android:layout_alignParentBottom="true">
<!-- cardview content -->
</androidx.cardview.widget.CardView>
</RelativeLayout>

I found another solution.
If you will wrap recyclerview in RelativeLayout, it will solve the problem easily.
Thanks.

How to achieve automatic width of Button in Android layout

I have a few Button listed vertically and I need all of them to have the same width, but also to display all text inside.
Basically I need width for all of them as a wrapped width of the largest one.
Hope I explained it well.
Now... I already have one layout that is working on my Samsung Galaxy S2 (4.1.2), but on friend's phone - Samsung GT-N7100 (note2) and android 4.4.2 - it is not working - some text is not displayed in the Button.
This is my layout:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:text="word"
android:layout_width="wrap_content"
android:layout_height="48dp"
android:textSize="30sp"
android:gravity="center"
android:layout_centerHorizontal="true"
android:id="#+id/word"/>
<TextView
android:text="14/36\nM: 1"
android:layout_width="fill_parent"
android:layout_height="80dp"
android:id="#+id/score"
android:layout_toRightOf="#+id/word"
android:gravity="right|center"
android:paddingRight="10dp"/>
<LinearLayout
android:layout_centerInParent="true"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/adapter">
<Button
android:text="1"
android:layout_width="match_parent"
android:layout_height="48dp"
android:id="#+id/opt1"/>
<Button
android:text="2"
android:layout_width="match_parent"
android:layout_height="48dp"
android:id="#+id/opt2" />
<Button
android:text="3"
android:layout_width="match_parent"
android:layout_height="48dp"
android:id="#+id/opt3" />
<Button
android:text="4"
android:layout_width="match_parent"
android:layout_height="48dp"
android:id="#+id/opt4" />
<Button
android:text="5"
android:layout_width="match_parent"
android:layout_height="48dp"
android:id="#+id/opt5" />
</LinearLayout>
<Button
android:text="Next"
android:layout_width="match_parent"
android:layout_height="48dp"
android:layout_alignParentBottom="true"
android:id="#+id/next"/>
</RelativeLayout>

Try setting android.width="auto"

You can extend the LinearLayout to force all its childs to have the max width:
// LinearLayoutButtonsHolder.java
package github.yaa110.widget;
import android.content.Context;
import android.util.AttributeSet;
import android.view.View;
import android.widget.LinearLayout;
public class LinearLayoutButtonsHolder extends LinearLayout {
public LinearLayoutButtonsHolder(Context context) {
super(context);
}
public LinearLayoutButtonsHolder(Context context, AttributeSet attrs) {
super(context, attrs);
}
public LinearLayoutButtonsHolder(Context context, AttributeSet attrs,
int defStyle) {
super(context, attrs, defStyle);
}
#Override
protected void onAttachedToWindow() {
super.onAttachedToWindow();
if (getChildCount() == 0) return;
getChildAt(getChildCount() - 1).addOnLayoutChangeListener(new OnLayoutChangeListener() {
#Override
public void onLayoutChange(View v, int left, int top, int right, int bottom, int oldLeft, int oldTop, int oldRight, int oldBottom) {
v.removeOnLayoutChangeListener(this);
for (int i = 0; i < getChildCount(); i ++) {
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT,
getChildAt(i).getMeasuredHeight());
getChildAt(i).setLayoutParams(lp);
}
}
});
}
}
Now in the xml file of your layout, use LinearLayoutButtonsHolder rather than LinearLayout. Do not forget to set the android:layout_width of each Button to wrap_content:
<github.yaa110.widget.LinearLayoutButtonsHolder
android:id="#+id/adapter"
android:layout_width="wrap_content"
android:orientation="vertical"
android:layout_centerInParent="true"
android:layout_height="wrap_content">
<Button
android:text="Long text for test"
android:layout_width="wrap_content"
android:layout_height="48dp"
android:id="#+id/opt1"/>
<Button
android:text="2"
android:layout_width="wrap_content"
android:layout_height="48dp"
android:id="#+id/opt2" />
<Button
android:text="3"
android:layout_width="wrap_content"
android:layout_height="48dp"
android:id="#+id/opt3" />
<Button
android:text="4"
android:layout_width="wrap_content"
android:layout_height="48dp"
android:id="#+id/opt4" />
<Button
android:text="5"
android:layout_width="wrap_content"
android:layout_height="48dp"
android:id="#+id/opt5" />
</github.yaa110.widget.LinearLayoutButtonsHolder>

use linearlayout like this
<LinearLayout
android:layout_centerInParent="true"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginLeft="20dp"
android:layout_marginRight="20dp"
android:id="#+id/adapter">

I have done this using XML only (no code) - for two TextViews. But the same technique should work for arbitrary number of buttons as well.
Say we have two TextViews A and B.
Wrap each TextView in a LinearLayout (with only one element inside) - La and Lb.
Set each TextView (A,B) width to 'wrap_content', set background transparent
Set the LinearLayouts (La,Lb) widths to 'match_parent', set background to whatever color/shape you want
Wrap La and Lb inside another Vertical LinearLayout container L, set the width/height of L to be 'wrap_content', height to 'wrap_content'
set padding on each TextView's LinearLayout (La, Lb) to make it look good
set margins on (La, Lb) to create spacing
That should do it.
Note: Make sure the background color/shape for each TextView is set via its background of individual layout container and not on the TextView itself.
I know this question was asked 3 years ago - but I think I saw same/similar questions elsewhere for a solution that involves XML only. So hope this helps someone in the future.

Textview with long text pushes out other views in GridLayout despite ellipsize=end

My problem is very similar to How to get a layout where one text can grow and ellipsize, but not gobble up the other elements on the layout, but read on below why I can't use TableLayouts as proposed there.
I'm trying to create a listview row that basically looks like this:
| TextView | View 1 | View 2 |
All views contain variable width elements. The TextView has ellipsize="end" set. View 1 should align left of the TextView, while View 2 should align to the right of the screen. So, normally, there would be whitespace between View 1 and View 2. As the text in the TextView grows longer, the TextView should grow, pushing View 1 to the right until there is no more whitespace left. Then, ellipsize should kick in, cutting of the text in TextView and appending an ellipsis ("...") at the end.
So, the result should look something like this:
+----------------------------------------+
| short text [view1] [view2] |
+----------------------------------------+
| long text with ell ... [view1] [view2] |
+----------------------------------------+
I've tried:
TableLayouts, but they seem to make scrolling extremely slow on some devices.
RelativeLayouts, but I either had overlapping views, or view1 or view2 disappeared completely.
GridLayouts, but the TextView always grows until it takes up the whole width of the screen, thus pushing view1 and view2 out of the screen.
This is the GridLayout I tried:
<GridLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<TextView
android:layout_gravity="left|fill_horizontal"
android:ellipsize="end"
android:singleLine="true"
android:text="Long text to demonstrate problem with TextView in GridLayout taking up too much space despite ellipsis" />
<TextView
android:layout_gravity="left"
android:text="(view1)" />
<TextView
android:layout_gravity="right"
android:text="(view2)" />
</GridLayout>
View 1 and View 2 are not really TextViews, I just used them in the example to simplify things.
Is there any way to achieve this without using TableLayouts?
EDIT:
As requested, here is my attempt at solving this with a RelativeLayout. The TextView takes up the full width of the screen in this case, so neither view1 nor view2 are visible.
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<TextView
android:id="#+id/rl0"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:ellipsize="end"
android:singleLine="true"
android:text="Long text to demonstrate problem with TextView in GridLayout taking up too much space despite ellipsis" />
<TextView
android:id="#+id/rl1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

I seem to have found a potential solution to prevent a TextView in GridLayout from growing unboundedly and pushing out other views. Not sure if this has been documented before.
You need to use fill layout_gravity and set an arbitrary layout_width or width on the long TextView in need of ellipsizing.
android:layout_gravity="fill"
android:layout_width="1dp"
Works for both GridLayout and android.support.v7.widget.GridLayout

I'm a big fan of LinearLayouts, so here's my suggestion using those:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_weight="1" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:ellipsize="end"
android:singleLine="true"
android:text="Long text to demonstrate problem with TextView in GridLayout taking up too much space despite ellipsis" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="(view1)" />
</LinearLayout>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right"
android:text="(view2)" />
</LinearLayout>

I will suggest you to play with layout_weight property of your widget
Example:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:weightSum="10">
<LinearLayout
android:id="#+id/ll_twoViewContainer"
android:layout_weight="8"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:id="#+id/rl0"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_weight="1"
android:ellipsize="end"
android:singleLine="true"
android:text="Long text" />
<TextView
android:id="#+id/rl1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_toRightOf="#id/rl0"
android:layout_weight="1"
android:minWidth="120dp"
android:text="(view1)" />
</LinearLayout>
<TextView
android:id="#+id/rl2"
android:layout_weight="2"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/rl1"
android:layout_alignParentRight="true"
android:layout_marginLeft="10dp"
android:text="(view2)" />
</LinearLayout>
</LinearLayout>
finally your layout will look like as follow:
+----------------------------------------+
| short text [view1] [view2] |
+----------------------------------------+
| long text with ell ... [view1] [view2] |
+----------------------------------------+

I think you should create custom layout for your purpose. I don't know how to do this using only default layouts/view and make it work for all cases.

The trick which worked for me was to use maxWidth to restrict the width of the first view. You need to do it with Java, here is the basic logic:
firstView.setMaxWidth(parentView.getWidth() - view2.getWidth() - view1.getWidth() - padding * 2);
Not pretty, but it works.

I think there's just a small issue on the layout that could be solved, anchoring the view3 to the right and start from there to force the view to have a delimited area (hence being able to properly set the ellipse):
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/rl3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:text="(view2)" />
<TextView
android:id="#+id/rl2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toLeftOf="#id/rl3"
android:text="(view1)" />
<TextView
android:id="#+id/rl1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ellipsize="end"
android:singleLine="true"
android:layout_alignParentLeft="true"
android:layout_toLeftOf="#id/rl2"
android:text="Long text to demonstrate problem with TextView in GridLayout taking up too much space despite ellipsis" />
</RelativeLayout>
Hope this helps...
Regards!

Try this
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:baselineAligned="false"
android:orientation="horizontal">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:gravity="center">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ellipsize="end"
android:singleLine="true"
android:text="Long text to demonstrate problem with TextView in GridLayout taking up too much space despite ellipsis"/>
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:gravity="center">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="left"
android:text="(view1)"/>
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:gravity="center">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right"
android:text="(view2)"/>
</LinearLayout>
</LinearLayout>
Currently, all views are centered. You can change android:gravity property to meet your needs. For example, you may want to align view1 right and view2 left in which case last two LinearLayouts would look something like (with 5dp margin on the right and left respectively):
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:gravity="center|right">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="left"
android:layout_marginRight="5dp"
android:text="(view1)"/>
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:gravity="center|left">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right"
android:layout_marginLeft="5dp"
android:text="(view2)"/>
</LinearLayout>

I find my solution for the case number 2 (the one with a long text):
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:weightSum="3" >
<TextView
android:id="#+id/rl0"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="3"
android:ellipsize="end"
android:singleLine="true"
android:text="Long text to demonstrate problem with TextView in GridLayout taking up too much space despite ellipsis" />
<TextView
android:id="#+id/rl1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_weight="1"
android:text="(view1)" />
<TextView
android:id="#+id/rl2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_weight="1"
android:text="(view2)" />
</LinearLayout>
The real problem is case one, and i didn't try a lot of things for this. I hope it helps (and if i have more spare time, i will try to achieve first one!).

If the views on the right get pushed over by the text by design, you might as well use a ListView instead of a GridView.
You would just need to make the base of the list item layout a RelativeLayout, and set rules like this:
You can set the two views on the right to alignParentRight (using android:layout_alignParentLeft="true"), but make sure the first view stays to the left of the second so it will push itself to the left as the views stretch out.
You can make the TextView on the left align to the left, but stay to the left of the first view (using android:layout_toLeftOf="#+id/viewId") so it won't overlap with the views.

Try using Layout Weight
<TableRow
android:id="#+id/tableRow3"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/tableRow2"
android:layout_alignParentBottom="true"
android:gravity="center"
android:weightSum="10"
android:background="#android:color/black" >
<TextView
android:id="#+id/txtInningsTotal"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="2"
android:gravity="center"
android:text="0"
android:textColor="#android:color/white" />
<TextView
android:id="#+id/txtTeamOneTotal"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="2.5"
android:gravity="center"
android:text="0"
android:textColor="#android:color/white" />
<View
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="0.2" />
<TextView
android:id="#+id/txtTeamTwoTotal"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="2.5"
android:gravity="center"
android:text="0"
android:textColor="#android:color/white" />
<View
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="0.2" />
<TextView
android:id="#+id/txtGrandTotal"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="3"
android:gravity="center"
android:text="0"
android:textColor="#android:color/white" />
</TableRow>
Here i have taken table row in which there is layout weight sum which is of 10 means that it is 100% width of its parent. and in all its child views i have set width to 0Dp and given weight to 1 or 2. so that it will take up to that percent of total 10. so the layout will be adjusted accordingly screen and also there will be no issue of overlapping.
If i have understood you correctly then this is the answer you wanted.
Hope it Helps!

First, you must layout [view 2] to parent Right;
Again, you reference the reference to the last two layout!
<Relativelayout android:layout_width="match_parent"
android:layout_height="wrap_content"
<TextView
android:id="#+id/view2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
/>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_toLeft="#id/view2"
android:gravity="left">
<TextView
android:id="#+id/shortORlongtTextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/view1"
android:ellipsize="end"
android:maxLines="1"
android:textSize="18dp"/>
<TextView
android:id="#+id/view1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
/>
</RelativeLayout>

I had the same problem with the grid layout. what i did is given a fixed width for the text view and also given layout_columnWeight property for each text view then the issue was fixed ,hope it helps ...
<TextView
android:id="#+id/txtName"
style="#style/MyDetailTitle"
android:layout_width="#dimen/detail_length"
android:layout_height="wrap_content"
android:text="#string/app_name"
app:layout_column="3"
app:layout_columnWeight="1"
app:layout_gravity="start"
app:layout_row="1" />

GridLayout is like the other things on Android : flawed by design.
You will need a custom Layout, the following example will allow you to layout things like:
[ label | short text | very long label | short text ]
[ long label | very very very | label | very long text ]
[ | long text | | ]

Have fun.

TableLayout will give expected behavior. May cause performance issue as question's author mention, but works great with simple layout. If the row is repeatable and scrollable, consider use gridview instead
<TableLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:stretchColumns="1"
android:shrinkColumns="0"
>
<TableRow>
<TextView/>
<View1/>
<View2/>
</TableRow>
</TableLayout>

Define maximum RelativeLayout size

I have to define 5 layouts on the screen and place them like a 3x3 grid. Layouts is empty.
At some moment I want programmatically to add some view on one layout and that view mustn't grows over allocated size of layout. In other words I want to have layout in which to put any view and it will be guaranty that it won't grows over that layout. Important note: I don't have rights to change manually size of added view, I only can to control its maximum size.
I have right now such layout:
<RelativeLayout
android:id="#+id/pluginsLayout"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="#+id/mainButtons"
android:layout_below="#+id/paramsLayout">
<RelativeLayout
android:id="#+id/capturingPluginLayout"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_gravity="fill_horizontal|left"
android:layout_above="#+id/processingPluginLayout">
</RelativeLayout>
<RelativeLayout
android:id="#+id/processingPluginLayout"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_gravity="fill_horizontal|left"
android:layout_above="#+id/filterPluginLayout">
</RelativeLayout>
<RelativeLayout
android:id="#+id/filterPluginLayout"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_gravity="fill_horizontal|left|bottom"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true">
</RelativeLayout>
<RelativeLayout
android:id="#+id/exportPluginLayout"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_gravity="fill_horizontal|right"
android:layout_above="#+id/viewfinderPluginLayout">
</RelativeLayout>
<RelativeLayout
android:id="#+id/viewfinderPluginLayout"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_gravity="fill_horizontal|bottom|right"
android:layout_toLeftOf="#+id/filterPluginLayout"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true">
</RelativeLayout>
</RelativeLayout>
And I added new view in code:
public void addVFPluginView(View view)
{
((RelativeLayout)MainScreen.thiz.findViewById(R.id.viewfinderPluginLayout)).addView(view);
}
I expect to got like this behaviour:
But I got only this, view fill entire parent layout:
Note: I use API8 (don't have GridLayout)

u can use grid layout in API8.

I've managed to solve this issue.
The main idea was to control view's sizes by myself programmatically.
I calculate appropriate proportion for each zone and when somebody add a new view to some of this layout I check suitability of the size of this view to the allocated size of layout. If size is not suitable I modify LayoutParams for this View.
Here is the xml of empty layouts:
<RelativeLayout
android:id="#+id/pluginsLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="#+id/mainButtons"
android:layout_below="#+id/paramsLayout">
<LinearLayout
android:id="#+id/capturePluginLayout"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true">
</LinearLayout>
<LinearLayout
android:id="#+id/processingPluginLayout"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true">
</LinearLayout>
<LinearLayout
android:id="#+id/filterPluginLayout"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentBottom="true">
</LinearLayout>
<LinearLayout
android:id="#+id/exportPluginLayout"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true">
</LinearLayout>
<RelativeLayout
android:id="#+id/viewfinderPluginLayout"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentBottom="true">
</RelativeLayout>
</RelativeLayout>
And like that I manage the size of adding views:
public void addVFPluginView(View view)
{
//Get maximum width and height for such plugins
int layoutHeight = this.getViewfinderLayoutHeight();
int layoutWidth = this.getViewfinderLayoutWidth();
//Calculate appropriate size of added plugin's view
android.widget.RelativeLayout.LayoutParams viewLayoutParams = (android.widget.RelativeLayout.LayoutParams)view.getLayoutParams();
viewLayoutParams = this.getTunedRelativeLayoutParams(view, viewLayoutParams, layoutWidth, layoutHeight);
//Get fixed maximum size for this plugin type
public int getViewfinderLayoutWidth()
{
return ((RelativeLayout)MainScreen.thiz.findViewById(R.id.pluginsLayout)).getWidth()/2;
}
public int getViewfinderLayoutHeight()
{
return (int)(((RelativeLayout)MainScreen.thiz.findViewById(R.id.pluginsLayout)).getHeight()*0.7);
}
((RelativeLayout)MainScreen.thiz.findViewById(R.id.viewfinderPluginLayout)).addView(view, viewLayoutParams);
}
android.widget.RelativeLayout.LayoutParams getTunedRelativeLayoutParams(View view, android.widget.RelativeLayout.LayoutParams currParams, int goodWidth, int goodHeight)
{
int viewHeight, viewWidth;
if(currParams != null)
{
viewHeight = currParams.height;
viewWidth = currParams.width;
if(viewHeight > goodHeight || viewHeight <= 0)
viewHeight = goodHeight;
if(viewWidth > goodWidth || viewWidth <= 0)
viewWidth = goodWidth;
currParams.width = viewWidth;
currParams.height = viewHeight;
view.setLayoutParams(currParams);
}
else
{
currParams = new android.widget.RelativeLayout.LayoutParams(goodWidth, goodHeight);
view.setLayoutParams(currParams);
}
return currParams;
}
Finally, next issue is for several views with suitable sizes but in sum they're bigger than allocated size. Maybe I'll just straightly count sizes of views and if the sum with the size of next adding view will be more than allocated size I just disallow to add this view.
