使用SurfaceView和MedioPlayer播放视频

添加权限：

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

布局：

/SurfaceViewPlayVideo/res/layout/activity_main.xml

<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" >    <SurfaceView        android:id="@+id/surfaceView"        android:layout_width="match_parent"        android:layout_height="360dp" />    <LinearLayout        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:layout_alignParentBottom="true"        android:gravity="center_horizontal"        android:orientation="horizontal" >        <ImageButton            android:id="@+id/play"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:src="@drawable/play" />        <ImageButton            android:id="@+id/pause"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:src="@drawable/pause" />        <ImageButton            android:id="@+id/stop"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:src="@drawable/stop" />    </LinearLayout></RelativeLayout>
