title: Android using LinearLayout as Background for all others LinearLayouts on the App
body: <p>I have a LinearLayout with 2 others LinearLayouts inside. Each one of this it have an ImageView inside.
  I need to set this LinearLayout as a Background for all the others LinearLayouts of my app.
  I tried with "Include" and "Merge", but it didn't work, because I need to put other LinearLayout inside my "background LinearLayout"
  Then i tried with "Styles", but I don't know how to add ImageViews inside LinearLayouts. It is possible?
  Finally right now I'm trying with "Drawable", but I don't know if that the solution.</p>
  
  <p>I need ideas, some help, can someone help me?</p>
  
  <p>This is my "background LinearLayout":</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  
  &lt;LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:orientation="vertical"
  android:background="@layout/gradient_background"&gt;
  
  &lt;LinearLayout
      android:layout_width="fill_parent"
      android:layout_height="wrap_content"
      android:gravity="center_horizontal"
      android:layout_marginTop="170dip"&gt; 
  
      &lt;ImageView
          android:id="@+id/background_title"
          android:src="@drawable/titulo_fondo"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"/&gt;
  
  &lt;/LinearLayout&gt;
  
  &lt;LinearLayout
      android:layout_width="fill_parent"
      android:layout_height="fill_parent"
      android:gravity="left|bottom"
      android:layout_marginLeft="-54dip"
      android:layout_marginBottom="-24dip"&gt; 
  
      &lt;ImageView
          android:id="@+id/background_logo"
          android:src="@drawable/circulo_logo"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"/&gt;
  
  &lt;/LinearLayout&gt; 
  
  &lt;/LinearLayout&gt;
