Change Relative layout width and height dynamically

Question

Hi i am using following layout structure inside LinearLayout

Answer 1

give an id to your relative layout in .xml :

android:id="@+id/relativelayout"

now in your java file write this:

RelativeLayout Rl = (RelativeLayout) findViewById(R.id.relativelayout);

RelativeLayout.LayoutParams layout_description = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.FILL_PARENT or YourUserDefinedwidth,
                        RelativeLayout.LayoutParams.FILL_PARENT or YourUserDefinedHeight);

Rl.setLayoutParams(layout_description);
