Center Layout in Parent

Question

I am having some issues with my layout. Basically I have two modes. Normal and Error. In normal mode I want to show the variable_one and variable_two linear layouts. In the error state I only want to show variable_one but centered in the main layout. The room name text must always remain in the same spot.

In the fragment code to set the visibility of variable_two I set the layout visibility to GONE

My layout is

<?xml version="1.0" encoding="utf-8"?>

                app:sizeToFit="true"/>
        </LinearLayout>
    </LinearLayout>
</LinearLayout>

Both variable_one and variable_two are set to wrap content. Is there a simple way to set variable_two as GONE and force variable_one to expand and center?

the two layout look basically the same. If layout *variable_one* is not that different from layout *variable_two*. you could just use one LinearLayout and make the views that are not relevant empty, invisible : btn1.setVisibility(View.GONE); btn1.setVisibility(View.INVISIBLE); — Guy West, Jun 30 '21 at 14:14

You don't need android:layout_weight nor android:layout_gravity. You just need to set android:gravity correctly. Use a android:gravity to specify the inner child's gravity.
