android layout margins with percentage

Question

I want to set margins by percentage.. I have 4 imageviews in a linearlayout and want to set default left,right,top,bottom margins that keep same percentage for each screen size.

is it possible ?

here is a demo what i want..

And here is what i've tried and doesn't work

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:orientation="vertical" >      <LinearLayout         android:layout_width="match_parent"         android:layout_height="match_parent"         android:layout_weight="1"         android:weightSum="10" >          <Thumbnail             android:id="@+id/thumb1"             android:layout_width="0dp"             android:layout_height="match_parent"             android:layout_weight="4" />          <Thumbnail             android:id="@+id/thumb2"             android:layout_width="0dp"             android:layout_height="match_parent"             android:layout_weight="4" />      </LinearLayout>      <LinearLayout         android:layout_width="match_parent"         android:layout_height="match_parent"         android:layout_weight="1"         android:weightSum="10" >           <Thumbnail              android:id="@+id/thumb3"              android:layout_width="0dp"              android:layout_height="match_parent"              android:layout_weight="4" >          </Thumbnail>          <Thumbnail             android:id="@+id/thumb4"             android:layout_width="0dp"             android:layout_height="match_parent"             android:layout_weight="4" />      </LinearLayout>  </LinearLayout> 

Thanks for your help

You can have invisible Views in your LinearLayouts as spacers and use the layout_weight mechanism to assign them relative size.

Example:

<LinearLayout     android:layout_width="match_parent"     android:layout_height="match_parent"     android:layout_weight="1">      <Thumbnail         android:id="@+id/thumb1"         android:layout_width="0dp"         android:layout_height="match_parent"         android:layout_weight="4" />      <View         android:layout_width="0dp"         android:layout_height="0dp"         android:layout_weight="2"         android:visibility="invisible"/>      <Thumbnail         android:id="@+id/thumb2"         android:layout_width="0dp"         android:layout_height="match_parent"         android:layout_weight="4" />  </LinearLayout>
