Question

又是关于Android的问题

public class PlayVideo extends Activity {
private VideoView videoView;
private MediaController mc ;
private String path ;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.other);
videoView = (VideoView) this.findViewById(R.id.videoView);
//path ="file:///sdcard/Movies/1.3gp";
//videoView.setVideoURI(Uri.parse(path));
path="E://movie.mp4";
mc = new MediaController(this);
videoView.setMediaController(mc);
videoView.setVideoPath(path);
videoView.setOnCompletionListener(new OnCompletionListener(){
public void onCompletion(MediaPlayer arg0) {
finish();
}
});
videoView.requestFocus();
videoView.start();
}
}

public class VideoPlayAcitvity extends Activity {

private Button button01;

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
button01 = (Button) findViewById(R.id.button01);
button01.setOnClickListener(new buttonListener());
}
class buttonListener implements OnClickListener {
public void onClick(View v) {

Intent intent = new Intent(VideoPlayAcitvity.this, PlayVideo.class);
VideoPlayAcitvity.this.startActivity(intent);
}
}
}
在上面的Andriod代码中，我在api当中查到这个方法，这个方法具体怎么用。我实在弄不明白

Answer 1

intent 是意图 安卓四大组件之一 这也要问？你先把安卓基础学好再说吧
