Android利用VideoView实现VideoPlayer

/** Called when the activity is first created. */

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

//Set the screen to landscape.

this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

mVideoView = (VideoView)findViewById(R.id.video_view);

//Video file

mUri = Uri.parse(Environment.getExternalStorageDirectory() + "/1.3gp");

//Create media controller

mMediaController = new MediaController(this);

mVideoView.setMediaController(mMediaController);

}

public void onStart() {

// Play Video

mVideoView.setVideoURI(mUri);

mVideoView.start();

super.onStart();

}

public void onPause() {

// Stop video when the activity is pause.

mPositionWhenPaused = mVideoView.getCurrentPosition();

mVideoView.stopPlayback();

Log.d(TAG, "OnStop: mPositionWhenPaused = " + mPositionWhenPaused);

Log.d(TAG, "OnStop: getDuration = " + mVideoView.getDuration());

super.onPause();

}

public void onResume() {

// Resume video player

if(mPositionWhenPaused >= 0) {

mVideoView.seekTo(mPositionWhenPaused);

mPositionWhenPaused = -1;

}

super.onResume();

}

public boolean onError(MediaPlayer player, int arg1, int arg2) {

return false;

}

public void onCompletion(MediaPlayer mp) {

this.finish();

}

}

本例中只是播放外存储器(一般是sd卡)上的1.3gp文件。在onCreate方法中创建了Media control，这个组件可以控制视频的播放，暂停，回复，seek等操作，不需要你实现。

//Create media controller

mMediaController = new MediaController(this);
