Android center view in FrameLayout doesn't work

Question

I have a FrameLayout in which I have 2 controls: - a custom view which draws a image and some text on it - a textview with a text

I want to center both in the FrameLayo

Answer 1

We can align a view in center of the FrameLayout by setting the layout_gravity of the child view.

In XML:

android:layout_gravity="center"

In Java code:

FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
params.gravity = Gravity.CENTER;

Note: use FrameLayout.LayoutParams not the others existing LayoutParams
