toggle visibility of chain group in constraint layout
If you are using beta version of constraintlayout, please follow @pavan's answer
If you are using AndroidX, Please follow below steps to integrate constraintlayout and Group:
1) Add AndroidX constraint layout dependancy in your project:
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
2) Use ConstraintLayout Group as below in your project:
<androidx.constraintlayout.widget.Group
android:id="@+id/groupDetails"
android:layout_width="wrap_content"
android:visibility="gone" // Default visibility for group views
app:constraint_referenced_ids="textViewUserName, ..." // id's which you want to include in group
android:layout_height="wrap_content"/>
3) Here is the coding part for toggle visibility:
private lateinit var groupDetails:Group
...
groupDetails = findViewById(R.id.groupDetails)
groupDetails.visibility = View.GONE // Change visibility
Hope it's helps while using AndroidX.
Yes, so now in ConstraintLayout
also we can handle visibility of particular groups of Views using the Group
This is a new feature introduced in ConstraintLayout which is currently in Beta version.
How to add beta ConstraintLayout
to your project? Follow the steps below:
Add maven support in project gradle file as below
allprojects {
repositories {
maven { url 'https://maven.google.com' }
jcenter()
}
}
Then in app gradle dependencies add ConstraintLayout library dependency
compile 'com.android.support.constraint:constraint-layout:1.1.0-beta3'
Now you have to add a Group
in your ConstraintLayout
as follows
<android.support.constraint.Group
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:constraint_referenced_ids="button7,button3,button2"
android:id="@+id/group" />
Where in Group
, the reference id...
app:constraint_referenced_ids="button7,button3,button2"
... contains the comma separated view id's you want to handle run time, so, in an Activity, you just bind the Group
as below and handle the visibility
import android.support.constraint.Group; //import statement in activity
Group group=(Group)findViewById(R.id.group); //bind view from xml
group.setVisibility(View.VISIBLE); //this will visible all views
group.setVisibility(View.GONE); //this will set Gone to all views
group.setVisibility(View.INVISIBLE); //this will set INVISIBLE to all view
