MediaController отстает от NavigationBar в FullScreen Video Activity

Question

У меня есть FullScreen Активность для воспроизведения видео, Все идет хорошо, пока я не коснусь экрана, чтобы просмотреть System Ui и Media Controller, но MediaController отстает от NavigationBar и его очень мужественный,

смотрите эти изображения, чтобы понять проблему:

Device1 - Normal State

Device1 - and MediaController Visible

и повторно мои коды: MyActivity:

public class ActivityPlayVideo4 extends Activity{ 

    public static final String KEY_VIDEO_URL = "videoUrl"; 
    String url; 
    ProgressView pvLoading; 

    private static final boolean AUTO_HIDE = true; 

    private static final int AUTO_HIDE_DELAY_MILLIS = 3000; 

    private static final boolean TOGGLE_ON_CLICK = true; 

    private static final int HIDER_FLAGS = SystemUiHider.FLAG_HIDE_NAVIGATION; 

    private SystemUiHider mSystemUiHider; 

    private VideoView mVideoView; 
    private MediaController mMediaController; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

     getWindow().getDecorView().setSystemUiVisibility(
       View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN|View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION); 

     setContentView(R.layout.activity_video_playing); 


     try { 
      url = getIntent().getExtras().getString(KEY_VIDEO_URL); 
     } catch (Exception e) { 
      url = ""; 
     } 


     mVideoView = (VideoView) findViewById(R.id.videoView); 

     // Set up an instance of SystemUiHider to control the system UI for 
     // this activity. 
     mSystemUiHider = SystemUiHider.getInstance(this, mVideoView, HIDER_FLAGS); 
     mSystemUiHider.setup(); 
     mSystemUiHider 
       .setOnVisibilityChangeListener(new SystemUiHider.OnVisibilityChangeListener() { 
        @Override 
        @TargetApi(Build.VERSION_CODES.HONEYCOMB_MR2) 
        public void onVisibilityChange(boolean visible) { 
         if (visible && AUTO_HIDE) { 
          delayedHide(AUTO_HIDE_DELAY_MILLIS); 
         } 
        } 
       }); 

     mVideoView.setOnCompletionListener(new PlayerOnCompleteVideo()); 
     mMediaController = new MediaController(this,false); 
     mMediaController.setMediaPlayer(mVideoView); 

     mVideoView.setMediaController(mMediaController); 
     mVideoView.requestFocus(); 


     pvLoading = (ProgressView) findViewById(R.id.pv_loading); 
     pvLoading.setVisibility(View.VISIBLE); 

     mVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() { 
      @Override 
      public void onPrepared(MediaPlayer mp) { 
       pvLoading.setVisibility(View.GONE); 
      } 
     }); 

     playVideo(); 

    } 


    @Override 
    protected void onPostCreate(Bundle savedInstanceState) { 
     super.onPostCreate(savedInstanceState); 
     delayedHide(100); 
    } 

    @Override 
    public boolean onOptionsItemSelected(MenuItem item) { 
     int id = item.getItemId(); 
     if (id == android.R.id.home) { 
      NavUtils.navigateUpFromSameTask(this); 
      return true; 
     } 
     return super.onOptionsItemSelected(item); 
    } 

    Handler mHideHandler = new Handler(); 
    Runnable mHideRunnable = new Runnable() { 
     @Override 
     public void run() { 
      mSystemUiHider.hide(); 
     } 
    }; 

    private void delayedHide(int delayMillis) { 
     mHideHandler.removeCallbacks(mHideRunnable); 
     mHideHandler.postDelayed(mHideRunnable, delayMillis); 
    } 

    private class PlayerOnCompleteVideo implements MediaPlayer.OnCompletionListener { 

     @Override 
     public void onCompletion(MediaPlayer mp) { 
      mVideoView.stopPlayback(); 
      playVideo(); 
     } 
    } 

    private void playVideo() { 
     mVideoView.setVideoURI(Uri.parse(url)); 
     mVideoView.start(); 
    } 

} 

и мой файл Layout (activity_video_playing.xml):

<?xml version="1.0" encoding="utf-8"?> 
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    tools:context=".view.activity.ActivityPlayVideo4"> 

    <RelativeLayout 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:layout_gravity="center" 
     > 

     <VideoView android:id="@+id/videoView" 
      android:layout_width="fill_parent" 
      android:layout_height="fill_parent" 
      android:keepScreenOn="true" 
      android:layout_centerInParent="true" 
      /> 


     <com.rey.material.widget.ProgressView 
      android:id="@+id/pv_loading" 
      android:layout_width="48dp" 
      android:layout_height="48dp" 
      app:pv_autostart="true" 
      app:pv_circular="true" 
      app:pv_progressStyle="@style/AppProgressStyle" 
      app:pv_progressMode="indeterminate" 
      android:layout_gravity="center" 
      android:layout_centerInParent="true" 
      android:visibility="gone" 
      /> 

    </RelativeLayout> 
</FrameLayout> 

Любой человек может мне помочь?!?!?

Answer 1

Я сделал так .. из here

mSystemUiHider 
     .setOnVisibilityChangeListener(new SystemUiHider.OnVisibilityChangeListener() { 

      @Override 
      @TargetApi(Build.VERSION_CODES.HONEYCOMB_MR2) 
      public void onVisibilityChange(boolean visible) { 

       if(visible){ 
        yourMediaController.show(); 

        //Also i generally add the actionbar here as well! 
        getActionBar().show(); 
       } else { 
        yourMediaController.hide(); 
        //Also i generally add the actionbar here as well! 
        getActionBar().hide(); 
       } 
       if (visible && AUTO_HIDE) { 
        // Schedule a hide(). 
        delayedHide(AUTO_HIDE_DELAY_MILLIS); 
       } 
      } 
     }); 

Надежда это поможет вам!
