通过此代码媒体控制器未显示，请帮助我如何在 vlc 媒体播放器的表面视图中显示媒体控制器以用于暂停、播放和搜索栏的视频位置。
【问题讨论】：
【参考方案1】：我遇到了同样的问题并找到了解决方案。 当然，现在回答为时已晚，但也许我会为某人节省一些时间。
要添加默认媒体控件，您需要通过以下方式实现它
-
从布局中删除 MediaController 并将一些用于媒体控制的容器添加到您的活动中（它将以编程方式添加）。
-
将控制器初始化添加到 onStart 活动或 onCreate
import android.widget.MediaController;
private MediaController controller;
@Override
protected void onStart()
super.onStart();
....
controller = new MediaController(this);
controller.setMediaPlayer(findViewByid(R.id.video_surface_frame));
controller.setAnchorView(mVideoSurfaceFrame);
mVideoSurfaceFrame.setOnClickListener(new View.OnClickListener()
public void onClick(View v)
controller.show(10000);
);
-
要定义playerInterface，需要像这样实现MediaController.MediaPlayerControl接口
private MediaController.MediaPlayerControl playerInterface = new MediaController.MediaPlayerControl()
public int getBufferPercentage()
return 0;
public int getCurrentPosition()
float pos = mLibVlc.getPosition();
return (int)(pos * getDuration());
public int getDuration()
return (int)mLibVlc.getLength();
public boolean isPlaying()
return mLibVlc.isPlaying();
public void pause()
mLibVlc.pause();
public void seekTo(int pos)
mLibVlc.setPosition((float)pos / getDuration());
public void start()
mLibVlc.play();
public boolean canPause()
return true;
public boolean canSeekBackward()
return true;
public boolean canSeekForward()
return true;
@Override
public int getAudioSessionId()
return 0;
;
-
启动您的应用并点击视频。您将看到默认媒体控件，它会在 10 秒内隐藏
祝你好运！

糟糕的答案 :) 对于那些想要实现播放器接口的人替换 controller.setMediaPlayer(findViewByid(R.id.video_surface_frame));与控制器.setMediaPlayer(playerInterface);谢谢【参考方案2】：公共类 Show_Array 扩展 AppCompatActivity 实现 IVLCVout.Callback
