Re-use Layouts with include

This example show how to use layout defined in seperated XML, using <include>. Such that you can re-use common view in your layout, or in separated layout.

The same layour included twice using <include>

Create the re-use layout, /res/layout/titlebar.xml.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:background="@android:color/background_dark">

    <ImageView android:layout_width="wrap_content"
               android:layout_height="wrap_content" 
               android:src="@drawable/ic_launcher" />
    
    <LinearLayout 
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">
        
        <TextView 
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:gravity="center"
            android:text="Android-Coding"
            android:textColor="@android:color/white"
            android:textStyle="bold"/>
        <TextView 
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:gravity="center"
            android:text="http://android-coding.blogspot.com/"
            android:textColor="@android:color/white"
            android:textStyle="italic"/>
        
    </LinearLayout>
</LinearLayout>

Include titlebar.xml in our main layout:

<RelativeLayout 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:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >
    
    <include layout="@layout/titlebar"
        android:id="@+id/topbanner"
        android:layout_alignParentTop="true"/>

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/topbanner"
        android:text="@string/hello_world" />
    
    <include layout="@layout/titlebar"
        android:id="@+id/topbanner2"
        android:layout_width="200dp"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_alignParentBottom="true"/>
</RelativeLayout>
