How to create ListView item that match material guideline - android

How to create ListView like this,
google has documentation about this,
https://material.io/guidelines/layout/metrics-keylines.html#metrics-keylines-keylines-spacing
But there is no explaination how to make this,
Here is my attempt so far, I'm not sure about the margin/padding and the separator, is there any tutorial how to make this layout
This is the RecyclerView item layout:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="16dp"
android:layout_marginStart="16dp"
android:layout_marginTop="10dp"

android:layout_marginLeft="16dp"
android:layout_marginStart="16dp"
android:layout_toEndOf="#id/image_layanan"
android:layout_toRightOf="#id/image_layanan"
android:textSize="13sp"
android:transitionName="text_pasien"/>
<View
android:layout_width="match_parent"
android:layout_height="1px"
android:layout_alignLeft="#+id/text_pasien"
android:layout_alignStart="#+id/text_pasien"
android:layout_below="#+id/text_pasien"
android:background="#212121"/>
</RelativeLayout>

To get partial divider (or whatever the name) I use this:
create a class extend RecyclerView.ItemDecoration
public class RecyclerViewItemDivider extends RecyclerView.ItemDecoration {
private static final int[] ATTRS = new int[]{android.R.attr.listDivider};
private Drawable mDivider;
public RecyclerViewItemDivider(Context context) {
final TypedArray a = context.obtainStyledAttributes(ATTRS);
mDivider = a.getDrawable(0);
a.recycle();
}
#Override
public void onDrawOver(Canvas c, RecyclerView parent, RecyclerView.State state) {
// this is the left start point for divider,
// I think there is better method without hardcoded the view
// main_content is my RectclerView item main content
// R.dimen.activity_horizontal_margin should be 16dp if use google guidelines
int left = (int)parent.findViewById(R.id.main_content).getX() +
(int)parent.getContext().getResources().getDimension(R.dimen.activity_horizontal_margin);
int right = parent.getWidth() - parent.getPaddingRight();
int childCount = parent.getChildCount();
for (int i = 0; i < childCount; i++) {
View child = parent.getChildAt(i);
RecyclerView.LayoutParams params = (RecyclerView.LayoutParams) child.getLayoutParams();
int top = child.getBottom() + params.bottomMargin;
int bottom = top + mDivider.getIntrinsicHeight();
mDivider.setBounds(left, top, right, bottom);
mDivider.draw(c);
}
}
}
Then you just need to use it like this:
RecyclerViewItemDivider divider = new RecyclerViewItemDivider(recyclerView.getContext());
recyclerView.addItemDecoration(divider);

((CoordinatorLayout.LayoutParams)_constraintLayoutHeader.LayoutParameters).Behavior = new StickyBottomBehavior(Resource.Id.lblJobLocation, Resource.Id.nestedScrollViewJobDetail, EPosition.Top);
}
In my custom behavior:
public class StickyBottomBehavior : CoordinatorLayout.Behavior
{
#region Properties

private int _scrollViewId;
private EPosition _position;
#endregion
#region Constructor
public StickyBottomBehavior(int anchorId, int scrollViewId, EPosition ePosition)
{

_scrollViewId = scrollViewId;
_position = ePosition;
}
#endregion
public override bool OnStartNestedScroll(CoordinatorLayout coordinatorLayout, Java.Lang.Object child, View directTargetChild, View target, int axes, int type)
{
return (axes == ((int)Vertical));
}
public override void OnNestedPreScroll(CoordinatorLayout coordinatorLayout, Java.Lang.Object child, View target, int dx, int dy, int[] consumed, int type)
{
var anchor = coordinatorLayout.FindViewById(_anchorId);
NestedScrollView scrollView = coordinatorLayout.FindViewById<NestedScrollView>(_scrollViewId);
CoordinatorLayout.LayoutParams layoutParams = (CoordinatorLayout.LayoutParams)scrollView.LayoutParameters;
int[] anchorLocation = new int[2];
View childView = child.JavaCast<View>();
anchor.GetLocationInWindow(anchorLocation);
switch (_position)
{
case EPosition.Top:
if (anchorLocation[1] < 0)
{
childView.Visibility = ViewStates.Visible;
layoutParams.TopMargin = childView.Height;
scrollView.LayoutParameters = layoutParams;
}
else
{
childView.Visibility = ViewStates.Invisible;
layoutParams.TopMargin = 0;
scrollView.LayoutParameters = layoutParams;
}
break;
case EPosition.Bottom:
if (anchorLocation[1] < 0)
{
childView.Visibility = ViewStates.Visible;
layoutParams.BottomMargin = childView.Height + 8;
scrollView.LayoutParameters = layoutParams;
}
else
{
childView.Visibility = ViewStates.Invisible;
layoutParams.BottomMargin = 0;
scrollView.LayoutParameters = layoutParams;
}
break;
default:
break;
}
}
}
public enum EPosition
{
Top,
Bottom
}
For the sticky buttons in the bottom it works very well but for the header there is smt wrong when I reach the Title in the top the screen is moving weirdly.
Demo: https://www.veed.io/view/6e1c9b71-b10d-46c7-a284-18b974a0bb7e
Is there another way to do that ? or there is smt wrong in my code ?
Thanks for the help.

Add view to constraintLayout with constraints similar to another child

I have a constraint layout (alpha9) with views spread all over it, and I have one particular ImageView that I need to replicate and add more of like it.
The layout is like so :
The main purpose is to animate 5 of those "coin" imageViews when the button is pressed. The imageViews i need to generated sha'll have exact properties of the the imageView behind the Button down below (with same constraints)
What i tried to do is the following :
private ImageView generateCoin() {
ImageView coin = new ImageView(this);
constraintLayout.addView(coin,-1,originCoinImage.getLayoutParams());//originCoinImage is the imageView behind the button
coin.setImageResource(R.drawable.ic_coin);
coin.setScaleType(ImageView.ScaleType.FIT_XY);
coin.setVisibility(View.VISIBLE);
return coin;
}
And it failed. EDIT: It failed to show what i wanted , sometimes it shows a coin in the top left of the screen , sometimes it doesn't show anything but either way , the number of coins increments (meaning the animation is trying to actually do something and then calling the onAnimationFinished method)
I used for animation the library EasyAndroidAnimations
the code is as follows :
MainActivity.java
#OnClick(R.id.addCoin)
public void addCoin() {
// for (int x = 0 ; x < 5 ; x++){
final View newCoin = generateCoin();
sendCoin(newCoin, 300, new AnimationListener() {
#Override
public void onAnimationEnd(com.easyandroidanimations.library.Animation animation) {
incrementCoins();
constraintLayout.removeView(newCoin);
shakeCoin(targetCoinImage, 200, null);
}
});
// }
}
private void incrementCoins() {
coins++;
coinNumber.setText(String.valueOf(coins));
}
private void sendCoin(View coinView, long duration, AnimationListener listener) {
new TransferAnimation(coinView)
.setDestinationView(targetCoinImage)
.setDuration(duration)
.setInterpolator(new AccelerateDecelerateInterpolator())
.setListener(listener)
.animate();
}
private void shakeCoin(View coinView, long duration, AnimationListener listener) {
new ShakeAnimation(coinView)
.setDuration(duration)
.setShakeDistance(6f)
.setNumOfShakes(5)
.setListener(listener)
.animate();
}

ConstraintLayout.LayoutParams cache its parameters, and is associated to the widget you use it on, so you cannot simply pass one widget's layoutParams to another.
You have to instead generate a new layoutParams for your new object, and copy the corresponding fields.
For example, if you have something like:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/content_main"
android:layout_width="match_parent"
android:layout_height="match_parent">
<Button
android:text="Button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/button"
android:layout_marginTop="16dp"
app:layout_constraintTop_toTopOf="parent"
android:layout_marginStart="16dp"
app:layout_constraintLeft_toLeftOf="parent"
android:layout_marginLeft="16dp" />
</android.support.constraint.ConstraintLayout>
Then you could do:
ConstraintLayout layout = (ConstraintLayout) findViewById(R.id.content_main);
ConstraintLayout.LayoutParams params =
(ConstraintLayout.LayoutParams) button.getLayoutParams();
Button anotherButton = new Button(this);
ConstraintLayout.LayoutParams newParams = new ConstraintLayout.LayoutParams(
ConstraintLayout.LayoutParams.WRAP_CONTENT,
ConstraintLayout.LayoutParams.WRAP_CONTENT);
newParams.leftToLeft = params.leftToLeft;
newParams.topToTop = params.topToTop;
newParams.leftMargin = params.leftMargin;
newParams.topMargin = params.topMargin;
layout.addView(anotherButton, -1, newParams);
This would put the second button exactly in the same place as the one defined in XML.

How to make custom ListView like attached image

I'm working with RSS Feed. I use ListView with Adapter to display data in custom view containing "LinearLayout with Image and Text". This view is repeated in each row. But, I need to make custom view like the image below to display data with different view.
Steps:
The tabbar can be done with horizontal scrollview with buttons inside. on button click change that button width and height. and reset last selected one.
the colored horziontal line can be another linear layout. you change its color on button click.
you can have to different layouts in the same listview. one for two items and one for one.
in adapter getCount method you should calculate the number of rows you have. beased on the algorithm used to decide which rows can have one item and which rows can have two.
That listview is not that complicated as you may think.
Working Example:
I created a github repository for it.
Adapter Class:
public class ArticlesAdapter extends ArrayAdapter<Article> {
int mod;
public ArticlesAdapter(Context context, int resource, ArrayList<Article> teams) {
super(context, resource, teams);
}
#Override
public View getView(int position, View view, ViewGroup parent) {
int resource = R.layout.single_item;
if (position % 2 == 0)
resource = R.layout.double_item;
if (position == getCount()-1 && mod == 1)
resource = R.layout.single_item;
if (view == null || view.getTag() != resource)
{
LayoutInflater vi = (LayoutInflater)getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = vi.inflate(resource, null);
view.setTag(resource);
}
TextView tv1 = (TextView)view.findViewById(R.id.textView1);
ImageView iv1 = (ImageView)view.findViewById(R.id.imageView1);
int index1 = (position * 3 / 2) + (position * 3) % 2;
Article article1 = getItem(index1);
tv1.setText(article1.getDesc());
iv1.setImageResource(article1.getImageUrl());
if (resource == R.layout.double_item)
{
TextView tv2 = (TextView)view.findViewById(R.id.textView2);
ImageView iv2 = (ImageView)view.findViewById(R.id.imageView2);
int index2 = index1 + 1;
Article article2 = getItem(index2);
tv2.setText(article2.getDesc());
iv2.setImageResource(article2.getImageUrl());
}
return view;
}
#Override
public int getCount() {
int count = super.getCount();
mod = count % 3;
count = count / 3 * 2;
return count + (mod > 0 ? 1 : 0);
}
}

Whatsapp Message Layout - How to get time-view in the same row

I was wondering how WhatsApp handles the time shown in every message.
For those who don't know:
If the message is very short, the text and time are in the same row.
If the message is long, the time is in the bottom right corner - the text wrapped around it.
With a RelativeLayout and toLeftOf I would get 1) but not 2) as previous lines would be "cut off" at the position of the time view. Same behaviour If i use a LinearLayout.
So I tried to use a FrameLayout or a RelativeLayout without any connection between text and time.
However, if the text is as long as the message-view is big, both views would overlap.
If I put blank characters to my message I wouldn't have the time on the right.
Do they really have some kind of text-wrapping-lib for this or is it possible to do only with layouts?
Here is the requested screenshot:
#Hisham Muneer 's answer very good.
But there are some problems. For example:
If the TextView has 2 full lines (end to end), the text will
intersect with datetime text layout. Finally, the views will
look like onion effect.
The text line wraps can't works efficiently. You must control this
lines and relocate the datetime view.
I'm going to share my solution, if you will need like this problem.

You can modify layout xml and some sections related your scenario.
There are 2 important point: you must define in layout xml "viewPartMain", "viewPartSlave" attributes. Because the code will decide measure via your main(chat textview) and slave(datetime text view) elements.
I wish have good days. Greets.
Adding HTML non-breaking spaces did the trick. Tested the code on most devices and working absolutely fine. Maybe whatsapp is also doing the same thing. Below is the chat code:

txtMsgFrom.setText(Html.fromHtml(convertToHtml(txtMsgFrom.getText().toString()) + "         ")); // 10 spaces
Its easier with Unicode from here.
So with this you can archive the Unicode format
new TextView("Hello\u00A0world");
better than HTML string.

simplified gravity + layout_gravity usage
left + right layout files

Two Public Methods
public abstract int getLineCount ()
Return the number of lines of text in this layout.
public int getLineWidth(int line)
Gets the unsigned horizontal extent of the specified line, including leading margin indent and trailing whitespace.
You can use the layout and code below to achieve the desired effect.
Source code gist
What I have used is get the width of the text + the time layout and check if this exceeds the container layout width, and adjust the height of the container accordingly. We have to extend from FrameLayout since this is the one which allows overlapping of two child views.
This is tested to be working on English locale. Suggestions and improvements are always welcome :)
Hope I've helped someone looking for the same solution.
I guess the easiest way to achieve this kind oflayout would be to add enough blank space in your message to be sure there is enough space on the right to not cover the time (I don't see any other easy way to have a margin/padding/positioning for the last line of your text only)
Then you just place the time in the relative as an align bottom right

I suggest other solution. If you know max bubble width and time width, then you can precalculate how to place your views.
Layout:
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView
android:id="#+id/text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="12sp"
tools:text="This is text"/>
<TextView
android:id="#+id/time"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="10sp"
tools:text="10:10"/>
</RelativeLayout>
Code:
fun setTextAndTime(textView: TextView, timeView: TextView, text: String, time: String) {
// screen width - offset from bubble
val maxWidth: Int = Resources.getSystem().displayMetrics.widthPixels - context.resources.getDimensionPixelSize(R.dimen.bubble_offset)
val timeWidth: Int = getTextWidth(time, 10f)
textView.text = text
timeView.text = time
textView.measure(makeMeasureSpec(maxWidth, EXACTLY), makeMeasureSpec(0, UNSPECIFIED))
val offset = textView.layout.getLineWidth(textView.layout.lineCount - 1)
val freeSpace = maxWidth - offset
val moveTimestampBelow = freeSpace < timeWidth
val multilineContent = textView.layout.lineCount > 1
val params = RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT)
when {
moveTimestampBelow -> params.apply {
addRule(RelativeLayout.BELOW, textView.id)
addRule(RelativeLayout.ALIGN_PARENT_RIGHT)
}
multilineContent -> params.apply {
params.addRule(RelativeLayout.ALIGN_BOTTOM, textView.id)
addRule(RelativeLayout.ALIGN_PARENT_RIGHT)
}
else -> params.apply {
params.addRule(RelativeLayout.ALIGN_BOTTOM, textView.id)
addRule(RelativeLayout.END_OF, textView.id)
}
}
timeView.layoutParams = params
}
private fun getTextWidth(text: String, textSizeSp: Float): Int {
val textPaint = Paint()
val pxSize = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_SP, textSizeSp, context.resources.displayMetrics)
textPaint.textSize = pxSize
textPaint.style = Paint.Style.FILL
val result = Rect()
textPaint.getTextBounds(text, 0, text.length, result)
return result.width()
}
The previous answers didn't satisfy my needs as they were too complex and the scrolling on RecyclerView was way too slow! I could feel the stutter while scrolling. So, I modified #Rahul Shuklas answer to make it more efficient. I am sharing my result below. The code is self explanatory, I have added comments for more understandability.

#TargetApi(21)
constructor(context: Context, attrs: AttributeSet, defStyleAttr: Int, defStyleRes: Int) : super(context, attrs, defStyleAttr, defStyleRes) {
}
override fun onMeasure(widthMeasureSpec: Int, heightMeasureSpec: Int) {
super.onMeasure(widthMeasureSpec, heightMeasureSpec)
doMeasure()
}
private fun doMeasure() {
val messageTextView = findViewById<TextView>(R.id.tv_message)
val dateTextView = findViewById<TextView>(R.id.tv_message_time)
// Message line count
val lineCount = messageTextView.lineCount
// Message padding
val messageTextViewPadding = messageTextView.paddingLeft + messageTextView.paddingRight
// First / Second last line of message
val lastLineStart = messageTextView.layout.getLineStart(lineCount - 1)
val lastLineEnd = messageTextView.layout.getLineEnd(lineCount - 1)
// Width of First / Second last line of message
var desiredWidth = Layout.getDesiredWidth(messageTextView.text.subSequence(lastLineStart,
lastLineEnd), messageTextView.paint).toInt()
var desiredHeight = measuredHeight
if (desiredWidth < minimumWidth && messageTextView.measuredWidth < minimumWidth) {
// Probably a small or single line message
desiredWidth = minimumWidth + messageTextViewPadding
} else {
// Probably a bit long or multiple line message
desiredWidth = messageTextView.measuredWidth + messageTextViewPadding
}
if(desiredHeight < minimumHeight) {
desiredHeight = minimumHeight
}
setMeasuredDimension(desiredWidth, desiredHeight)
}
}

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"
android:layout_toRightOf="#id/rl0"
android:layout_marginLeft="10dp"
android:text="(view1)" />
<TextView
android:id="#+id/rl2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/rl1"
android:layout_alignParentRight="true"
android:layout_marginLeft="10dp"
android:text="(view2)" />
</RelativeLayout>
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: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>
