You can use VideoView. See example of usage here.

Adding VideoView to layout XML file is as any other component, for example (taken from android site):

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    >

    <VideoView 
        android:id="@+id/surface_view" 
        android:layout_width="320px"
        android:layout_height="240px"
    />

</LinearLayout>
