You forgot to call mT1layout.setLayoutParams(paramsT1)
or mT1layout.invalidate()
after changing the height.
Change RelativeLayout Height

Frage
I want to change te height of a Relative layout. I want to change it from 70dp to 80dp when you push on a button. I checked if the button works with visibility change and is does work.
I have searched for answers see Link Changing relative layout programmatically
in that answers this code is mentioned:
RelativeLayout rl = (RelativeLayout) findViewById(R.id.yourId);
rl.getLayoutParams().height = 100;
rl.getLayoutParams().width = 100;
I tried the above code and it wont work, Nothing happens. see my code:
public void next (View view){
if (view == mnext){
RelativeLayout.LayoutParams paramsT1 = (RelativeLayout.LayoutParams)mT1layout.getLayoutParams();
// Changes the height and width to the specified *pixels*
paramsT1.height = 300;
}
}
This is my .XML The Relativelayout is placed in a linearlayout.
<LinearLayout
android:id="@+id/linearLayout2"
android:layout_width="fill_parent"
android:layout_height="70dp"
android:orientation="horizontal" >
