Android 媒体 Controller 短时间显示

Question

下面的这个 Activity 工作正常，但 mediaController 仅在我单击屏幕时显示。第二个问题是媒体 Controller 只显示 3 秒。我应该怎么做才能消除这个问题？

public class PlayingActivity extends Activity
{

    private VideoView mVideoView;
    private EditText mPath;
    MediaController mediaController;

    @Override
    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.playingactivity);
        mPath = (EditText) findViewById(R.id.path);
        mPath.setText(GlobalVariable.getstrEmail());
        mVideoView = (VideoView) findViewById(R.id.surface_view);
        Uri uri = Uri.parse("/sdcard/download/test.mp3");
        mediaController = new MediaController(this);
        mediaController.findFocus();
        mediaController.setEnabled(true);
        mediaController.show(0);
        mediaController.setAnchorView(mVideoView);
        mVideoView.setMediaController(mediaController);
        mVideoView.setVideoURI(uri);
        mVideoView.start();
    }
}

Answer 1

mediaController.requestFocus();

将在视频开始时立即显示(无需点击)

和

mVideoView.setOnPreparedListener(new OnPreparedListener() {

            @Override
            public void onPrepared(MediaPlayer mp) {
                mediaController.show(0);
            }
        });

将其保留在屏幕上。希望对你有帮助
