ConstraintLayout: Center two buttons horizontally - android

Although it seems simple I couldn't make it, I would like the two buttons to touch each other from their sides and to be centered horizontally, like so:
I tried the answers in this thread: Center two buttons horizontally, but it only relates to RelativeLayout and not ContrainstLayout
I also tried to play with
app:layout_constraintHorizontal_chainStyle="spread"
But no success. My not-helpful xml:
<?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"
android:background="#color/colorBackground"
tools:context=".MainActivity">
<Button
android:id="#+id/button"
style="#style/btnStyle"
android:layout_height="wrap_content"
android:layout_marginStart="16dp"
android:background="#color/btnTrue"
android:text="Button"
android:textColor="#ffffff"
app:layout_constraintEnd_toStartOf="#+id/button2"
app:layout_constraintHorizontal_bias="1.0"
app:layout_constraintHorizontal_chainStyle="spread"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<Button
android:id="#+id/button2"
style="#style/btnStyle"
android:layout_height="wrap_content"
android:layout_marginEnd="56dp"
android:background="#color/btnFalse"
android:text="Button"
app:layout_constraintEnd_toEndOf="parent"
tools:layout_editor_absoluteY="0dp" />
</androidx.constraintlayout.widget.ConstraintLayout>
Is this possible to achieve with ConstraintLayout?


This should do a job.
<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="match_parent">
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button"
app:layout_constraintEnd_toStartOf="#+id/button2"
app:layout_constraintHorizontal_chainStyle="packed"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_chainStyle="packed" />
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toEndOf="#id/button"
app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>
Key is removing not needed parameters and use
app:layout_constraintHorizontal_chainStyle="packed"


You have to create a horizontal chain for both buttons with chain style packed
Here is a sample
<?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">
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#000"
android:text="Button"
android:textColor="#ffffff"
app:layout_constraintEnd_toStartOf="#+id/button2"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintHorizontal_chainStyle="packed"/>
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#ad11"
android:text="Button"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toEndOf="#+id/button"
app:layout_constraintTop_toTopOf="parent"/>
</androidx.constraintlayout.widget.ConstraintLayout>
Output:


You can do it putting the buttons inside a horizontal LinearLayout
<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">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent">
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:backgroundTint="#color/colorPrimary"
android:text="Button"
android:textColor="#ffffff" />
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:backgroundTint="#color/colorAccent"
android:text="Button" />
</LinearLayout>
</androidx.constraintlayout.widget.ConstraintLayout>

android:layout_height="wrap_content"
android:background="#color/green"
android:text="Button"
app:layout_constraintEnd_toStartOf="#+id/guideline"

android:text="Button"
app:layout_constraintStart_toStartOf="#+id/guideline"
app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>


For such construct your views width needs to be 0dp. Also for button2, make sure it is from button1 and till parent's end horizontally. You have not shown your style so there may be other issues.

Set value of property to value of another views property in XML?

In Android's XML layout system, I'd like to be able to set the value of one views property to the value of another views property.
For example, something like this:
android:layout_marginRight="#id/rightBarButton:width"
Would set the marginRight value of this view to the width value of the rightBarButton view.
I already know I can do this programmatically, but is there a way to do this in XML?

Use constraint layout you don't need to specify margin just give right constraint of button1 to left constraint of buttonRight like this
<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="match_parent"

Android constraint layout barrier causing button cut at the end

This is what the resulting image looks like -

Based on the conversation on what exactly what the OP needs, constraint guideline will produce the intended result:
<?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">
<TextView
android:id="#+id/textView"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginStart="16dp"
android:layout_marginTop="16dp"
android:layout_marginEnd="16dp"
android:text="abcdefghijklkkkkkkkkkkkfghjqwertzuiopasdfghhjklyabcdefghijklkkkkkkkkkkkfghjqwertzuiopasdfghhjklyabcdefghijklkkkkkkkkkkkfghjqwertzuiopasdfghhjklyabcdefghijklkkkkkkkkkkkfghjqwertzuiopasdfghhjkly"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="#id/guideline"
app:layout_constraintTop_toTopOf="parent" />
<Button
android:id="#+id/button"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginStart="16dp"
android:layout_marginLeft="16dp"
android:layout_marginTop="16dp"
android:text="Button"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="#id/guideline"
app:layout_constraintTop_toTopOf="parent" />
<androidx.constraintlayout.widget.Guideline
android:id="#+id/guideline"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
app:layout_constraintGuide_percent="0.8" />
</androidx.constraintlayout.widget.ConstraintLayout>
The above code produces the following if the text keeps growing, it ensures the button stays on the screen like the following:
If you don't want the button to be cut at the end & wrap instead, add an End constraint:
app:layout_constraintEnd_toEndOf="parent"
So your button xml should be like the following:
<Button
android:id="#+id/button"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginStart="16dp"
android:layout_marginLeft="16dp"
android:layout_marginTop="16dp"
android:text="Button"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toEndOf="#id/barrier"
app:layout_constraintTop_toTopOf="parent" />
The resulting output will be like this:
Now if you want otherwise, like the button would remain/retain its own size and the textview will not, then set the barrier direction to start instead of end & pass button as constraint referenced ids instead of textview like the following:
<android.support.constraint.Barrier
android:id="#+id/barrier"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:barrierDirection="start"
app:constraint_referenced_ids="button" />

I tried this way blow,and it works.

Android constraint layout divide in horizontal

I'm working with an Android project and I used ConstraintLayout.
I want to design the layout as two blocks which stay in horizontal line. Each block will get 50% of the width:
How can I do this with ConstraintLayout?

There are Two ways you can do this.
Using Chain Constraint
Using Guideline Constraint
1st : Using Chain Constraint
<?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"
android:layout_width="match_parent"
android:layout_height="match_parent">
<Button
android:id="#+id/button"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="Button"
app:layout_constraintEnd_toStartOf="#+id/button2"
app:layout_constraintHorizontal_bias="0.5"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<Button
android:id="#+id/button2"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="Button"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0.5"
app:layout_constraintStart_toEndOf="#+id/button"
app:layout_constraintTop_toTopOf="parent" />
</android.support.constraint.ConstraintLayout>
2nd : Using Guideline Constraint
<android.support.constraint.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="match_parent">
<Button
android:id="#+id/button"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="Button"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="#id/guideline1"
app:layout_constraintTop_toTopOf="parent" />
<Button
android:id="#+id/button2"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="Button"
app:layout_constraintLeft_toLeftOf="#id/guideline1"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<android.support.constraint.Guideline
android:id="#+id/guideline1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
app:layout_constraintGuide_percent="0.5" />
</android.support.constraint.ConstraintLayout>
Output : Both gives same output.

How to handle the following case for ConstraintLayout, when one of the targets of layout_constraint visibility changed to View.GONE

I want to avoid nested layout, to improve my app performance.
Hence, I tried the following
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_margin="30dp"
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:id="#+id/title_text_view"
android:background="#ffd600"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="Title\nTitle"
app:layout_constraintEnd_toStartOf="#+id/pin_text_view"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<TextView
android:id="#+id/pin_text_view"
android:background="#ff0000"
android:textColor="#ffffff"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toTopOf="parent"
android:text="Pin" />
<TextView
android:id="#+id/body_text_view"
android:background="#304ffe"
android:textColor="#ffffff"
android:layout_width="0dp"
android:layout_height="0dp"
app:layout_constraintTop_toBottomOf="#+id/title_text_view"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
android:text="Body" />
</android.support.constraint.ConstraintLayout>
The output is as follow.
During runtime, I might change the visibility of title_text_view (yellow) to View.GONE.
But, it will looks like the follow. I don't wish pin_text_view (red) to be covered up by body_text_view (blue)
What I wish to have is
One of the way to overcome, is after changing the visibility of title_text_view (yellow) to View.GONE, I need use Java code to manual update app:layout_constraintTop_toBottomOf of body_text_view (blue) - Android : How to programatically set layout_constraintRight_toRightOf "parent"
From
<TextView
android:id="#+id/body_text_view"
...
app:layout_constraintTop_toBottomOf="#+id/title_text_view"
to
<TextView
android:id="#+id/body_text_view"
...
app:layout_constraintTop_toBottomOf="#+id/pin_text_view"
But, this will make my code more difficult to be maintained.
Is there any easier way, without involving Java code, and without nested layout?

You can use a barrier, which is available in ConstraintLayout since version 1.1
So if you are using an older version of ConstraintLayout, change the dependency for ConstraintLayout in your build.gradle to
implementation 'com.android.support.constraint:constraint-layout:1.1.0'
or a later version.
Then add the barrier to your layout like following:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_margin="30dp"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<TextView
android:id="#+id/title_text_view"
android:background="#ffd600"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="Title\nTitle"
app:layout_constraintEnd_toStartOf="#+id/pin_text_view"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<TextView
android:id="#+id/pin_text_view"
android:background="#ff0000"
android:textColor="#ffffff"
android:layout_width="wrap_content"

For further information see this link

you can get closest to your requirement using below code without adding any extra code:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_margin="30dp"
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:id="#+id/title_text_view"
android:background="#ffd600"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="Title\nTitle"
android:visibility="visible"
app:layout_constraintEnd_toStartOf="#+id/pin_text_view"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<TextView
android:id="#+id/pin_text_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginEnd="8dp"
android:background="#ff0000"
android:text="Pin"
android:textColor="#ffffff"
app:layout_constraintEnd_toEndOf="#+id/body_text_view" />
<TextView
android:id="#+id/body_text_view"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_marginTop="8dp"
android:background="#304ffe"
android:text="Body"
android:textColor="#ffffff"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/pin_text_view" />
OR if you want to do some extra xml code you can do something like this using guidelines feature in constraintLayout:
<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:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="30dp">
<TextView
android:id="#+id/title_text_view"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginBottom="8dp"
android:background="#ffd600"
android:padding="5dp"
android:text="Title\nTitle"
android:visibility="visible"
app:layout_constraintBottom_toTopOf="#+id/guideline"
app:layout_constraintEnd_toStartOf="#+id/pin_text_view"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<android.support.constraint.Guideline
android:id="#+id/guideline"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
app:layout_constraintGuide_percent="0.09" />
<TextView
android:id="#+id/pin_text_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginEnd="8dp"
android:background="#ff0000"
android:text="Pin"
android:textColor="#ffffff"
app:layout_constraintEnd_toEndOf="#+id/body_text_view" />
<TextView
android:id="#+id/body_text_view"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_marginTop="8dp"
android:background="#304ffe"
android:text="Body"
android:textColor="#ffffff"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="#+id/guideline" />
</android.support.constraint.ConstraintLayout>
