here layout design

the reason not want convert relativelayout linear layout, because add transparent view on top of view2 , view 4 receive gesture event.

change ur entire layout linear layout this. add weight accordingly need.i didnt add weight.this sample code.

<linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/mainview" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="horizontal">  <view     android:layout_width="220dp"     android:layout_height="wrap_content"     android:background="#000000" />  <linearlayout     android:layout_width="match_parent"     android:layout_height="match_parent"     android:orientation="vertical">      <view         android:layout_width="wrap_content"         android:layout_height="100dp"         android:background="#ffffff" />      <view         android:layout_width="wrap_content"         android:layout_height="100dp"         android:background="#000000" />      <view         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:background="#bbbbbb" />   </linearlayout>
