ConstraintLayout Groups

ConstraintLayout's Group allows you to define a set of UI elements as a group and control their visibility, visibility changes, and other properties as a single entity programmatically.

Here's how you can use it:

1. Define your ConstraintLayout group in XML:

<androidx.constraintlayout.widget.Group
    android:id="@+id/group_example"
    android:layout_width="0dp"
    android:layout_height="0dp"
    app:constraint_referenced_ids="textView1, button1, imageView1" />
        

2. Manipulate the group programmatically:

Group group = findViewById(R.id.group_example);

// Hide the entire group
group.setVisibility(View.GONE);

// Show the entire group
group.setVisibility(View.VISIBLE);
        

3. Perform dynamic UI changes efficiently:

Instead of individually changing the visibility of multiple UI elements, you can manipulate them as a group. This can significantly simplify your code and improve its readability, especially when dealing with complex layouts that require frequent visibility changes.

4. Optimize performance:

ConstraintLayout's Group feature can help optimize performance by reducing the number of layout passes needed for visibility changes. Since you're changing the visibility of multiple UI elements simultaneously, ConstraintLayout can handle these changes more efficiently compared to updating each element individually.

By utilizing ConstraintLayout's Group feature, you can streamline your Android UI development process and make your code more maintainable and efficient.
