Android Multimedia Development Notes [1] -- using SurfaceView + MediaPlayer to develop the simplest Video Player

Use the interfaces provided by the android SDK to develop the simplest video playback demo.
Next, paste the source code of main. xml:
[Html]
<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/surfaceView1"
Android: layout_width = "wrap_content"
Android: layout_height = "360dp"
Android: layout_alignParentLeft = "true"
Android: layout_alignParentRight = "true"
Android: layout_alignParentTop = "true"/>
 
</RelativeLayout>

Next, paste the program source code:

@ Override
Public void onCreate (Bundle savedInstanceState ){

SurfaceView = (SurfaceView) this. findViewById (R. id. surfaceView1 );

SurfaceView. getHolder (). addCallback (new Callback (){
@ Override
Public void surfaceDestroyed (SurfaceHolder holder ){

}
@ Override

// Start playing

}
@ Override
Public void surfaceChanged (SurfaceHolder holder, int format, int width,

}
 
Private void play (){

// Output the video image to SurfaceView

} Catch (Exception e ){
// TODO: handle exception
}
}
 
@ Override
Public boolean onCreateOptionsMenu (Menu menu ){
