android原生自带的播放器一般只能播放本地视频，而没有播放url的功能。不过android系统中有一个VideoView的控件可以实现这一功能。
简单实现如下：
public class MyVideoPlay extends Activity implements MediaPlayer.OnErrorListener, MediaPlayer.OnCompletionListener { public static final String TAG = "MyVideoPlay"; private VideoView mVideoView; private Uri mUri; private int mPositionWhenPaused = -1; private MediaController mMediaController; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.video_view); //Set the screen to landscape. this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); mVideoView = (VideoView)findViewById(R.id.my_video_view); //Video file Intent it = getIntent(); mUri = Uri.parse(it.getStringExtra("netUrl")); //Create media controller mMediaController = new MediaController(this); mVideoView.setMediaController(mMediaController); mVideoView.setOnCompletionListener(new OnCompletionListener() {@Overridepublic void onCompletion(MediaPlayer mp) {// TODO Auto-generated method stubMyVideoPlay.this.finish();}}); } public void onStart() { // Play Video if (mVideoView != null && mUri != null) { mVideoView.setVideoURI(mUri); mVideoView.start(); } else { Toast.makeText(MyVideoPlay.this, "发生错误", Toast.LENGTH_SHORT).show(); } super.onStart(); } public void onPause() { mPositionWhenPaused = mVideoView.getCurrentPosition(); mVideoView.stopPlayback(); 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) { MyVideoPlay.this.finish(); }} 截图：
