<?xml version="1.0" encoding="utf-8"?>  
<RelativeLayout  
  xmlns:andro  
  android:layout_width="fill_parent"  
  android:layout_height="wrap_content">  
  <ImageView  
    android:  
    android:layout_width="wrap_content"  
    android:layout_height="wrap_content"  
    android:layout_alignParentLeft="true"  
    android:src="@drawable/icon"  
    />  
  <Button  
    android:  
    android:layout_width="wrap_content"  
    android:layout_height="wrap_content"  
    android:layout_alignParentRight="true"  
    android:text="button"  
    />     
  <LinearLayout  
    android:orientation="vertical"  
    android:layout_width="fill_parent"  
    android:layout_height="wrap_content"  
    android:layout_toLeftOf="@id/button"  
    android:layout_toRightOf="@id/icon_left"  
    >  
    <TextView  
        android:layout_width="fill_parent"  
        android:layout_height="wrap_content"  
        android:text="trust you"  
        />  
    <TextView
