<SurfaceView
Android: id = "@ + id/surfaceview"
Android: layout_width = "320px"
Android: layout_height = "240px"

/>

1. Obtain surfaceview -------- surfaceview = (surfaceview) findviewbyid (R. Id. surfaceview );

2. Obtain surfaceholder ------- surfaceholder = surfaceview. getholder ();

Surfaceholder. settype (surfaceholder. surface_type_push_buffers); // set the display content to be pushed from the outside.

Surfaceholder. addcallback (this); // a class instance is required to implement the surfaceholder. Callback interface.

3. instantiate a player mediaplayer = new mediaplayer ();

Mediaplayer. setdatasource ("http://www.bogotobogo.com/Video/sample.3gp"); // sets the data source

Mediaplayer. setdisplay (surfaceholder); // The settings are displayed in the surfaceview

Mediaplayer. setAudioStreamType (AudioManager. STREAM_MUSIC); // you can specify the stream format.

Mediaplayer. prepare ();

Mediaplayer. start ();
