I am attempting to design a chat item in a RecyclerView with constraint layout but a can't set the flexible width correctly.
Android constraint layout:
<?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/receive_message_wrapper"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/receive_message_label"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAlignment="textStart"
android:textColor="#color/receive_message_box_text"
android:background="#drawable/message_recieve"
android:padding="#dimen/message_box_padding"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toStartOf="#id/receive_time_label"
app:layout_constraintHorizontal_chainStyle="spread_inside"
/>
<TextView
android:id="#+id/receive_time_label"
android:layout_width="wrap_content"
app:layout_constrainedWidth="true"
android:layout_height="wrap_content"
android:text="timestamp"
android:textAlignment="textEnd"
android:layout_marginStart="#dimen/space_between_message_element"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintStart_toEndOf="#id/receive_message_label"
app:layout_constraintEnd_toEndOf="parent"
tools:ignore="HardcodedText"
/>
</android.support.constraint.ConstraintLayout>
It works well but if I show some longer message, the timestamp is hidden by receive message label.
The solution from anber is good, but the chat content textView will have extended width, even when the content is very short, which may become not good.
I also did something very similar. Finally I used a solution as:
use a LinearLayout (or any other layout) which has width=0 (match_constraint) to replace the TextView
move TextView as child of above layout, and set its width=wrap_content
Thus the time will show anyway, and the chat content width is still wrapped.
UPD. My previous solution was incorrect as #aimin-pan mentioned.
you should set for you message textView
android:layout_width="wrap_content" and app:layout_constrainedWidth="true", and right constraint before left side of time textView.
And time textView just align on top-right of parent.
In this case if you have short text it will be wrap context:
And if the text is long it will also correct wrap:

In your time TextView remove this line
app:layout_constraintStart_toEndOf="#id/receive_message_label"
So, the time label is not constrained to the message, but only the message to the time.
Set also the message label width to 0dp
android:layout_width="0dp"
Place a Blank View After Time textView
<View
android:id="#+id/view"
android:layout_width="0dp"
android:layout_height="0dp"
app:layout_constraintBottom_toBottomOf="#+id/constraintLayout3"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toEndOf="#+id/constraintLayout3"
app:layout_constraintTop_toTopOf="#+id/constraintLayout3" />

I'm using a RecyclerView to show a list of country codes, countries and flags respecively. The app is supporting RTL, so the layout of item is a simple Constraintlayout with 3 elements:
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.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:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/selectable_background">
<ImageView
android:id="#+id/countryFlag"
android:layout_width="24dp"
android:layout_height="24dp"
android:scaleType="centerInside"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<TextView
android:id="#+id/countryName"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:textAlignment="viewStart"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toStartOf="#+id/countryCode"
app:layout_constraintStart_toEndOf="#+id/countryFlag"
app:layout_constraintTop_toTopOf="parent" />
<TextView
android:id="#+id/countryCode"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>
But sometimes I get this visual representation in RTL (Arabic) like this, where some items are not aligned properly. See Angola and Anguilla country items:
You need a fixed width for the country code, this is what is misaligning the text
There is no reason for countryName to fill the entire width, the constraint layout's width is already match_parent and countryName's start already aligned to the flag's end.
Align using constraints is much more stable then android:textAlignment attribute.
Edit it as follows
<TextView
android:id="#+id/countryName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toStartOf="#+id/countryCode"
app:layout_constraintStart_toEndOf="#+id/countryFlag"
app:layout_constraintTop_toTopOf="parent" />
Happy to help
basically I have an layout as shown in the image. I am using a Guideline to restrict the width of the blue box. This means the ConstraintLayout itself hase full screen width and the blue box has its layout_constraintEnd_toStartOf="#id/guideline".
The blue box is just the background color of the TextView with the text, there aren't any additional containers or anything.
In order for the blue box to respect the constraints for its width calculations I have to set layout_constrainedWidth="true" on the box. As you can see the width is then restricted but the problem is that wrap_content does not work correctly afterwards.
The first box shows that if the text is only a single line, then the behaviour is as expected but if the text spans multiple lines (as in the second box) wrap_content breaks and the box is always "full width" (start of screen until the guideline).
Did somebody experience something similar? Is this a bug or did I misunderstood something. The same broken behaviour can be observed with the grey box on the right side.
I assume this has to do with the breaking behaviour of the TextView but is there a fix or workaround? As far as I know outside of an ConstraintLayout the width would be equal to the text so I assume this is a bug.
Edit XML code:
This is the basice code of one of the "bubbles" and as already mentioned I would like the view to really be as wide as the text.

I have one TextView aligned to the left and centered vertically. Two groups of ImageView and TextView are both aligned to the right, with two layout configurations, one with image on the right, another with image on the left.
The hello world text can be very long. I want it to expand to fill the whole width without covering up the left text.
I have added app:layout_constraintStart_toEndOf="#id/text1" to constraint the right group (image + text) not to overlap with the left text. However, it does not behave as I expected.
How to make it not overlapping using only ConstraintLayout?
Text1 will be covered up if the right text is too long, which is not expected. Be noted that the image on the second row is gone too.

expected to be like below if the right text is too long. It can achieved by LinearLayout and RelativeLayout
Kindly check the Constraintlayout version. Use app:layout_constrainedWidth="true"
with android:layout_width="wrap_content"
You can use Guidelines to stop your text from expanding more than needed.
let's take this layout for example:
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.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:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<TextView
android:layout_width="0dp"
android:layout_height="match_parent"
android:gravity="center"
android:text="longgggggg texttttttttttttttttexttttttttttttttttexttttttttttttttttexttttttttttttttt"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="#+id/guideline2"
app:layout_constraintTop_toTopOf="parent" />
<TextView
android:id="#+id/textView"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="TextView"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toStartOf="#+id/guideline2"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<androidx.constraintlayout.widget.Guideline
android:id="#+id/guideline2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
app:layout_constraintGuide_percent="0.18" />
And because of app:layout_constraintGuide_percent="0.18" and android:layout_width="0dp" on both text views the long textView will not exit its constraints.
I had a similar issue, the problem was that I was mixing left and start, so the view was constrained from Right to Left, but the left was set as constraintStartToParent.
Changing everything to start / end solved the issue.
I have ConstraintLayout with two TextView inside:
<androidx.constraintlayout.widget.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/first"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/second"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintLeft_toRightOf="#+id/first"
app:layout_constraintRight_toRightOf="parent"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</androidx.constraintlayout.widget.ConstraintLayout>
I want to place the first one at the top left-corner of parent container and to place the second one at the top-right parent's corner. But both textviews can have text with any length. And when first one has very long text it overlaps the second textview. I can solve this problem by wrapping both textviews in LinearLayout. But this way seems to me inelegant. Maybe there is another way to do it? I mean with ConstraintLayout's feautures
First of all, remove the wrap_content from your widths as this makes the left/right constraints irrelevant. Use 0dp in its place to make it adhere to the constraints' rules.
Then create a horizontal chain between the views and have it as spread, so that the views don’t overlap at any point and they also stay at the edges of the screen at all times.
Finally, align the texts accordingly so that the left one aligns to the start of the view and the right one aligns to the end. In the example below you see that no matter how long the text is, the views don’t overlap and stick to their sides.
NOTE: It is considered better practice to use start/end constraints (as in my code) instead of left/right in order to cater for devices with different text direction. You can also modify the code below by adding the appropriate margins to have the text farther away from the edges of the screen.

This way second TextView won't overlap first one for sure, but there might happen that first is too long so that there is no place for second one. If that could be the case I would recommend setting maxWidth to first TextView, so that in worst case scenario there is some space left for second TextView.
Also I added graviti to second one to keep text on right side of TextView.

Consider the following layout:
<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/container"

android:layout_height="wrap_content">
<TextView
android:id="#+id/text_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ellipsize="end"
android:maxLines="1"
android:padding="8dp"
android:textSize="18sp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
tools:text="Text" />
<ImageView
android:layout_width="48dp"
android:layout_height="48dp"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0"
app:layout_constraintStart_toEndOf="#id/text_view"
app:layout_constraintTop_toTopOf="parent"
tools:background="#android:color/black" />
</android.support.constraint.ConstraintLayout>
The image view (or button, or any other widget, important is that it has a fixed size) is aligned right/end of a TextView with a size of wrap_content, thus, the text itself only takes the space it needs.
What I now want is, when the text expands (aka if it's longer), that the button gets aligned to the right of the parent, and the text view only gets the width that is left and gets ellipsized.
At the moment, the image view is pushed outside and the text gets ellipsized once it fills the whole parent.
I tried to fix this by adding a endToEnd="parent" constraint the the image and setting the horizontal bias to 0 (see code), but that doesn't work.
Any suggestions on what I could do instead?
In order to prevent the ImageView from getting pushed outside the parent you need to constrain the end of the TextView to the start of the ImageView to create a chain. Now to ensure that the TextView only takes the space it needs but also has its constraints enforced, you need to add app:layout_constrainedWidth="true" attribute to your TextView.
If you want the ImageView to stay immediately to the right of the TextView can use packed chain style with a horizontal bias of 0.
If you want the ImageView to be aligned to the right of the parent you can use the spread_inside chain style without bias.
The resulting XML with above changes might look like this:

EDIT: As requested in the comment, here's how it would work with a Barrier sparating the 3 TextViews and the ImageView. In this case you don't specify the constraints for the ends of the TextViews thus you no longer have them chained horizontally. Instead, you create a Barrier with the direction being the end of all TextViews that are referenced in the Barrier. This will ensure that the Barrier is always at the end of the widest TextView. The last thing to do is to constrain the start side of the ImageView to the Barrier.
