I hope to put some item into a gridview like following :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/llBg"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
android:orientation="vertical"
android:paddingBottom="40dp" >
<ImageView
android:id="#+id/mudImg"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
android:scaleType="fitCenter"
android:src="#drawable/icon_m0_r"
android:visibility="visible" />
<TextView
android:id="#+id/mudTitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_marginTop="8dp"
android:gravity="center"
android:text="fsafdsf"
android:textColor="#color/white"
android:textSize="16dp" />
</LinearLayout>
While the 'mudImg' part got something wrong with the image's size on a true android machine.Actually It never works util I set a indeed num to 'layout_width' and 'layout_height' like '50dp' or something like this.
What I want is show the origin size image and if necessary expended to the size what the parent view left to it.
Now my solution is that calculating the image size with app screen params(height width) and parent view's margins and gridview's numColumns and setting the result by code (since can not do it in xml)
any better idea?
Try this for your ImageView:
<ImageView
android:id="#+id/mudImg"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:src="#drawable/icon_m0_r"
android:visibility="visible" />
adjustViewBounds="true" tells the ImageView to set the height so that the image has the correct aspect ratio using the given width.
I am trying to layout a view that should wrap its content, but it shouldn't be more than ~100dp less than its parent width. How can I do that using a RelativeLayout or some other layout? What I have right now will always make the view 100dp less than its parent so that there is space for another view.
This picture is an example of what I have:
As you can see, the text doesn't fill the whole box, so it could be smaller. But, it should never be larger than 100dp less than its parent, so that there is room for the time the message was sent.
This is my layout.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clipChildren="false"
android:orientation="vertical"
android:paddingBottom="10dp"
android:paddingRight="#dimen/horizontalMargin"
android:paddingTop="10dp">
<TextView
android:id="#+id/message_holder"
android:layout_toLeftOf="#id/blank"
android:layout_alignParentLeft="true"
android:layout_marginLeft="#dimen/horizontalMargin"
android:background="#drawable/message_corners"
style="#style/white_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="alsdkjf; alsdkf" />
<RelativeLayout
android:id="#+id/blank"
android:layout_width="wrap_content"
android:layout_height="1dp"
android:layout_alignParentRight="true"
android:minWidth="100dp">
</RelativeLayout>
<TextView
android:minWidth="100dp"
android:id="#+id/time"
style="#style/gray_text"
android:layout_toRightOf="#id/message_holder"
android:paddingLeft="10dp"
android:text="Yesterday,\n11:30 PM" />
<RelativeLayout
android:layout_width="40dp"
android:layout_height="40dp"
android:layout_alignBottom="#id/message_holder"
android:layout_alignParentLeft="true"
android:background="#drawable/triangle" />
</RelativeLayout>
I have tried using the "minWidth" property on a blank view to the right of the message box to provide spacing, but it doesn't resize to be larger (which would make the message box smaller). When I don't have the blank view, and simply place the time TextView to the right of the message box, then that TextView isn't visible when the message box expands.
Update:
This is my "message_corners.xml":
<?xml version="1.0" encoding="utf-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid
android:color="#color/green" >
</solid>
<padding
android:left="10dp"
android:top="10dp"
android:right="10dp"
android:bottom="10dp" >
</padding>
<corners
android:radius="10dp">
</corners>
</shape>
Update 2:
This is what I am looking for in a layout with short text:

Short message
Long message
I know this is a really old question, but it's a frustrating problem I've encountered several times now and the existing answers weren't quite what I was looking for. Some colleagues and I came up with the following:
<?xml version="1.0" encoding="utf-8"?>
<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="wrap_content"
android:orientation="vertical"
android:background="#FFFFFF">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#888888"
android:padding="10dp"
android:orientation="horizontal">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:background="#00FF00"
tools:text="Short message."/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_weight="0"
android:background="#CCCCCC"
tools:text="Yesterday,\n11:30pm"/>
</LinearLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:background="#888888"
android:padding="10dp"
android:orientation="horizontal">
<TextView
android:id="#+id/message_text_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:background="#00FF00"
tools:text="Super ultra mega awesome long message which is going to help us take over the world."/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_weight="0"
android:background="#CCCCCC"
tools:text="Yesterday,\n11:31pm"/>
</LinearLayout>
</LinearLayout>
Which looks like this when rendered:
The magic seems to be the zero value for the weight of the text box on the right (in addition to the non-zero weight value of the text box on the left, which some of the other answers already have).
Honestly, I can't explain exactly why it works, but after having looked for a solution to this for so long I'm not questioning it! :)
As an aside, I like this approach because it doesn't require any explicit or minimum widths, any intermediate wrapper views, or the use of clipping settings, margins, padding, etc. to implement view overlay.
What the author of this question really asks is, how to let the TextView expand to fit the message inside of it without overflowing the time TextView, and without leaving blank spaces.
Since you don't actually know the width of the whole screen, you can't tell your TextView to be 100dp less than it.
What you should do is wrap your TextView in a container which will have the toLeftOf rule, with the TextView only wrapping it's contents. This way, the container will expand all the way up to the right (without overflowing the time TextView) but the TextView will only wrap it's text contents (so, it won't extend any blank spaces)
Code
Instead of
<TextView
android:id="#+id/message_holder"
android:layout_toLeftOf="#id/blank"
android:layout_alignParentLeft="true"
android:layout_marginLeft="#dimen/horizontalMargin"
android:background="#drawable/message_corners"
style="#style/white_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="alsdkjf; alsdkf" />
Use
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toLeftOf="#id/blank"
android:layout_alignParentLeft="true"
android:layout_marginLeft="#dimen/horizontalMargin">
<TextView
android:id="#+id/message_holder"
android:background="#drawable/message_corners"
style="#style/white_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="alsdkjf; alsdkf" />
</LinearLayout>
By the way, your layout isn't very good. You should optimize it.
You can try the following arrangement of views and their widths:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="6dp"
>
<FrameLayout
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#android:color/holo_blue_bright"
tools:text="Some long test is this which is support to wrap at the end of parent view"
/>
</FrameLayout>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="6dp"
tools:text="Yesterday,\n 11:30 PM"
/>
</LinearLayout>

This can also be achieved using ConstraintLayout
with 2 children in horizontal chain
1st child
layout width 0
constraint weight 1
constraint max width wrap
2nd child
layout width wrap content
A solution with ConstraintLayout using
app:layout_constrainedWidth
layout_constraintHorizontal_bias
layout_constraintHorizontal_chainStyle
.
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<EditText
android:id="#+id/edt_left"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Sample content"
app:layout_constrainedWidth="true"
app:layout_constraintEnd_toStartOf="#id/button_right"
app:layout_constraintHorizontal_bias="0"
app:layout_constraintHorizontal_chainStyle="packed"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<Button
android:id="#+id/button_right"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Right Button"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toEndOf="#id/edt_left"
app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>
If you want to make time text on right and text message on its left, you can do something like that ( using this in relative layout) also you can use maxWidth not minWidth
<TextView
android:id="#+id/view_textView_timeText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"/>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_toLeftOf="#id/view_textView_timeText"
android:maxWidth="100dp"/>
What you could do is put an empty view between the 2 views and keep its width as MATCH_PARENT and assign the textview to leftof this empty view and the empty view to left of the date view. Just make sure to keep the view empty.
As i understand you want to make the layout or the textview to be 100 dp less than the screen size
Which you can do by getting the screen width in pixels which is done by this
Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
int width = size.x;
int height = size.y;
Then you could set the textbiew width to be less 100dp from the screen size hope this help
P.s I think you might want to convert dp to px but i am not sure
You can do like this(not the direct answer for the question ):
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="bottom"
android:orientation="horizontal">
<LinearLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:orientation="horizontal">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ellipsize="end"
android:maxLines="1"
android:paddingLeft="45px"
android:text="asdfadsfsafasdfsakljkljkhjhkkhjkjhjkjhjkhjkhljkhlkhjlkjhljkhljkhlkjhljkhljkhlfasd"
android:textColor="#4a4a4a"
android:textSize="40px" />
</LinearLayout>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:maxLines="1"
android:paddingLeft="45px"
android:paddingRight="48px"
android:text="2017.08.09 13:00"
android:textColor="#9b9b9b"
android:textSize="34px" />
</LinearLayout>
I have a common solution to solve this kind of layout question:
Create a specific ViewGroup!
For the question above, the key point is how to set the correct maxWidth to the content view.
Create a SpecialViewGroup. The contentView is the left view, and the timeView is the right view.
class SpecialViewGroup #JvmOverloads constructor(
context: Context, attrs: AttributeSet? = null, defStyleAttr: Int = 0
) : LinearLayout(context, attrs, defStyleAttr) {
private lateinit var contentView: TextView
private lateinit var timeView: TextView
override fun onAttachedToWindow() {
super.onAttachedToWindow()
contentView = findViewById(R.id.content)
timeView = findViewById(R.id.time)
}
override fun onMeasure(widthMeasureSpec: Int, heightMeasureSpec: Int) {
// measure the timeView firstly, because the contentView's maxWidth rely on it.
timeView.measure(
MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED),
MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED),
)
// then caculate the remained space for the contentView
val parentWidth = MeasureSpec.getSize(widthMeasureSpec)
val paddingHorizontal = paddingStart + paddingEnd
val view1MaxWidth = parentWidth - timeView.measuredWidth - paddingHorizontal
// set the maxWidth to the contentView
contentView.maxWidth = view1MaxWidth
// The rest thing will be handed over by LinearLayout
super.onMeasure(widthMeasureSpec, heightMeasureSpec)
}
}
Use the SpecialViewGroup in your layout, like the usual LinearLayout.
<com.example.SpecialViewGroup
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#FFBB86FC"
android:orientation="horizontal"
android:padding="10dp">
<TextView
android:id="#+id/content"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#FF3700B3"
android:padding="10dp"
android:text="adaasdasdasasdadasdasdaaaaaaaaaaaaaaaa"
android:textColor="#color/white" />
<TextView
android:id="#+id/time"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:background="#FF018786"
android:padding="10dp"
android:text="1970-01-01"
android:textColor="#color/white" />
</com.example.archview.SpecialViewGroup>
And the result:
The benefits of this approach are obvious:
No extra nesting Layout.
Common to solve the similar layout questions.
Had the similar issue. Made it works with constraint.
<ConstraintLayout>
<TextView
android:id="#+id/title"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:ellipsize="end"
android:maxLines="2"
app:layout_constraintEnd_toStartOf="#+id/option_info"
app:layout_constraintHorizontal_chainStyle="packed"
app:layout_constraintHorizontal_weight="1"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintWidth_max="wrap" />
<ImageView
android:id="#+id/option_info"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_info"
app:layout_constraintBottom_toBottomOf="#+id/title"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toEndOf="#+id/title"
app:layout_constraintTop_toTopOf="#+id/title" />
</ConstraintLayout>
I have a custom view/layout that need to be sized based on the contents of the children. The layout looks like this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="100dp"
android:layout_height="64dp"
android:orientation="vertical">
<LinearLayout
android:id="#+id/rectangle"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:background="#drawable/rectangle"
android:orientation="horizontal"
android:padding="5dp">
<ImageView
android:id="#+id/iconImageView"
android:layout_width="32dp"
android:layout_height="32dp"
android:layout_gravity="center_vertical|left"
android:contentDescription="Icon"
android:src="#drawable/iconplaceholder"
android:scaleType="fitCenter"/>
<TextView
android:id="#+id/labelTextView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginLeft="10dp"
android:textColor="#color/white"
android:gravity="center|left"
android:textSize="16dp"
android:text="Hello"/>
</LinearLayout>
<View
android:id="#+id/triangle"
android:layout_width="20dp"
android:layout_height="20dp"
android:layout_gravity="center_horizontal"
android:background="#drawable/triangle"
android:rotation="180"/>
</LinearLayout>
What I would like to do is:
List item
Allow the view to have a max width
Make sure that the entire text of #+id/labelTextView of the text view is visible in the view and allow it to grow taller if needed, but not get any wider than the max width.
If the text is really short, the view should just be as wide as needed
Set the size of the #+id/iconImageView from code and make sure that the parent view is resized accordingly
I guess I need to override onMeasure of my view, but please advice if this is the correct way. Also, how can I measure the size of a TextView given a set of constraints, like a max width?
I would think you would be able to set the layout_height for the parent to wrap_content. This way, it sets its view to be the size it needs to be depending on the sizes of the children inside it.
I've got a ListActivity with a custom Adapter. This adapter uses the following list_item.xml:

In the Adapter's getView-method I've added the following piece of code:
// Change the width of the Filler-Space to match the Image
// and leave the height as is
Space space = (Space) view.findViewById(R.id.filler_space);
space.setLayoutParams(new LinearLayout.LayoutParams(
imageView.getMeasuredWidth(), space.getMeasuredHeight()));
This gives the following result at first:
When I change the Visibility of my second LinearLayout (ll2) to VISIBLE, it gives the following result:
What I want instead is:
As it seems the Space-View width isn't changed at all.. While I know for fact that the getView methods are successfully called thanks to Log-messages and other things I do in the getView method.
Does anyone know what I did wrong?
PS: When I use View instead of Space I have the same result. Never used Space before, so I thought it might have to do something with that.
Solution thanks to Demand's option 4:
// Since we can't access Measured widths and heights before the View is completely loaded,
// we set up an Observer that will be called once the ListItem's layout is ready
ViewTreeObserver observer = view.getViewTreeObserver();
if(observer.isAlive()){
// In order to access the view in the onGlobalLayout, it needs to be final, so we create a final copy here
final View v = view;
observer.addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
// This will be called once the layout is finished, prior to displaying it
#Override
public void onGlobalLayout() {
ImageView imageView = (ImageView) v.findViewById(R.id.image);
Space space = (Space) v.findViewById(R.id.filler_space);
// Change the width of the Filler-Space to match the Image and leave the height as is
space.setLayoutParams(new LinearLayout.LayoutParams(imageView.getMeasuredWidth(), space.getMeasuredHeight()));
}
});
}
You set width and height if your space to wrap_content. It's mean that space will have width as their children, but there is no children and you have width = 0. It's not about space, it's about layout measuring in android.
When you call your code:
Space space = (Space) view.findViewById(R.id.filler_space);
space.setLayoutParams(new LinearLayout.LayoutParams(
imageView.getMeasuredWidth(), space.getMeasuredHeight()));
Your imageView havn't measured yet and return width = 0. It will measured later before drawing. In getView() in adapter you only create views, but measuring, layout and drawing will be later.
You have several ways to fix it:
set width of your space in dp, instead of wrap_content.
using relative layout instead of three linear layouts.
Use TableLayout.
add GlobalTreeObserver and getMeasuredWidth() at right time.
Post your runnable to view's handler to get width after drawing.
I think the best ways is 2 and 3, because 4 and 5 will cause measuring several times.
I have an activity where the bottom half of the page is a scrollable results view. At the top of the results view, is a relativelayout with some text and a button. This button will make new items appear in this relative layout to refine the search. This part is all working. However, below this relative layout, I need to add a list of search results. I had this working with a listview, but since I need the entire bottom of the portion of the page (including that header relative layout) scrollable and since you cant have a listview in a scrollview, this wont work.
So, I was hoping I could do something like make another view, populate it with the result data for each result item, and programatically add them below the relative layout. Perhaps just having a linearlayout beneath that header relative layout.
Am I on the right track with this thinking? What is the right way to do this?
If it matters, my app has a min sdk version of 8. I am using the support libraries.
EDIT: here is my current code:

Basically, I want to know if I should just try to add my result items (which I currently have as a seperate .XML file) and if so how I do that. Or if there is some other device I should be using to accomplish this. My goal, is to have everything in that scrollview to scroll. I don't know how many result items I will have until the page is loaded.
How about, we actually put the ListView in a ScrollView!
I know people say you can't, but I found a way.
1. Wrap the layout that contains your ListView, with a ScrollView.
2. Add this to the class with the layout containing your ListView. Make sure to place it after you set your adapter. The only thing you need to change is dp to the height of your ListView row layout.
int listViewAdapterSize = yourListView.getAdapter().getCount();
LayoutParams listViewParams = yourListView.getLayoutParams();
final float scale = getContext().getResources().getDisplayMetrics().density;
int pixels = (int) ((listViewAdapterSize * dp) * scale + 0.5f);
params.height = pixels;
Let me know if you have any problems!
