Answer 1

Based on the knowledge that your code works.

Change the FrameLayout for a vertical linear layout i.e. it lays out it's children below each other.

LinearLayout parentLayout = new LinearLayout(this);
LinearLayout linearLayout1= new LinearLayout(this);
LinearLayout linearLayout2= new LinearLayout(this);

LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);

params.gravity = Gravity.CENTER_VERTICAL;

parentLayout.setOrientation(VERTICAL);
parentLayout.addView(linearLayout1, params);
parentLayout.addView(linearLayout2, params);
