Answer 1

<LinearLayout
...
layout_height="fill_parent"
orientation="vertical"
weightSum="100">
  <LinearLayout
   layout_width="fill_parent"
   layout_height="0dp"
   layout_weight="70"
  >
  </LinearLayout>
  <RelativeLayout
   layout_width="fill_parent
   layout_height="0dp"
   layout_weight="30">
  </RelativeLayout
</LinearLayout>

It's just a draft but i hope you do understand.

Answer 2

Use this in each layout to set a margin by dp to each other layout

android:layout_marginTop="10dip"
// can be marginBottom, etc

The sample below just does what you need programatically. I have used a fixed size of (140,398).

LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(140, 398);
        layoutParams.setMargins(24, 0, 24, 0);
        layout.addView(layoutParams);
