thanks in advance.

in case problem happens in screen consider using linearlayout weights, give responsive design independent screen size or resolution - instead render percentage making views take same percentage of screen no matter screen size is.
attached xml sample weighted screen.

<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:tools="http://schemas.android.com/tools"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:orientation="vertical" >      <linearlayout         android:layout_width="match_parent"         android:layout_height="0dp"         android:layout_weight="90"         android:orientation="horizontal" >          <linearlayout             android:layout_width="0dp"             android:layout_height="match_parent"             android:layout_weight="90"             android:background="#8000ff00"             android:orientation="vertical" >              <!-- green view -->         </linearlayout>          <linearlayout             android:layout_width="0dp"             android:layout_height="match_parent"             android:layout_weight="10"             android:background="#80ff0000"             android:orientation="vertical" >             <!-- red view -->         </linearlayout>     </linearlayout>      <linearlayout         android:layout_width="match_parent"         android:layout_height="0dp"         android:layout_weight="10"         android:background="#800000ff" >          <!-- bottom blue view -->     </linearlayout>  </linearlayout>
