  import android.media.MediaPlayer;
  import android.os.Bundle;
  import android.util.Log;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_video_player);

        final VideoView videoView = (VideoView) findViewById(R.id.videoView1);
        videoView.setVideoPath("http://www.ebookfrenzy.com/android_book/movie.mp4");

        MediaController mediaController = new MediaController(this);
        mediaController.setAnchorView(videoView);
        videoView.setMediaController(mediaController);

        videoView.setOnPreparedListener(new 
                MediaPlayer.OnPreparedListener()  {
            @Override
            public void onPrepared(MediaPlayer mp) {
                progDailog.dismiss();
                Log.i(TAG, "Duration = " + videoView.getDuration());
            }
        });

        videoView.start();
        progDailog = ProgressDialog.show(this, "Please wait ...", "Retrieving data ...", `enter code here`true);

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.video_player, menu);
        return true;
    }

}

在VideoView中播放http视频

这是我的代码:

public static void getVideoFromHttp(String urlPath) {

try {
// Start the MediaController
MediaController mediacontroller = new MediaController(mContext);
mediacontroller.setAnchorView(mVideoview);
// Get the URL from String VideoURL
Uri mVideo = Uri.parse(urlPath);
mVideoview.setMediaController(mediacontroller);
mVideoview.setVideoURI(mVideo);

} catch (Exception e) {
Log.e("Error", e.getMessage());
e.printStackTrace();

}

mVideoview.requestFocus();
mVideoview.setOnPreparedListener(new OnPreparedListener() {
// Close the progress bar and play the video
public void onPrepared(MediaPlayer mp) {
    mVideoview.start();

}
});

mVideoview.setOnCompletionListener(new OnCompletionListener() {

public void onCompletion(MediaPlayer mp) {

}
});

}

谢谢
