android - 点击按钮后如何在android中播放视频

Question

我正在尝试在 android 中设计简单的代码以在单击按钮后播放视频，但我遇到了未知问题。我现在的项目文件如下。我现在一头雾水。请指出一件事或解决这个问题。再次感谢！

public class VideoActivity extends Activity {
    VideoView video;
    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);
        play = (Button)findViewById(R.id.button1);


        play.setOnClickListener(new View.OnClickListener() {
           public void onClick(View v) {

               VideoView myVideoView = (VideoView)findViewById(R.id.myvideoview);
               myVideoView.setVideoPath("/mnt/usb_storage/vivek.3gp");
               myVideoView.setMediaController(new MediaController(this));
               myVideoView.requestFocus();
               myVideoView.start();
           }
        });

    }
}

btnPlay.setOnClickListener(new View.OnClickListener() 
            {
                @Override
                public void onClick(View v) 
                {
                    try 
                    {
                        videoView.setVideoPath(videoPath);
                        videoView.setMediaController(new MediaController(Applicaion Context or YourActivity.this));
                        videoView.start();

                    }
                    catch (Exception e) 
                    {
                        e.printStackTrace();
                        System.out.println("Error in btnInfo Click -->"+e.toString());
                    }
                }
            });
            //BtnPlay
