Android - 對話框中的VideoView的MediaController出現在對話框後面

Question

我在自定義對話框中有一個VideoView，我正在創建一個媒體控制器VideoView在飛行中並將它分配給代碼中的VideoView，但控制器doesn實際上並沒有出現在視頻上 - 它出現在對話框後面！任何想法如何讓控制器在視頻之上？

我創建了一個靜態的對話框輔助類來幫助構建自定義對話框：

public class DialogHelper { 

    public static Dialog getVideoDialog(Context context, Uri videoLocation, boolean autoplay) { 
     final Dialog dialog = getBaseDialog(context,true, R.layout.dialog_video); 

     ((Activity)context).getWindow().setFormat(PixelFormat.TRANSLUCENT); 
     final VideoView videoHolder = (VideoView) dialog.findViewById(R.id.video_view); 
     videoHolder.setVideoURI(videoLocation); 
     //videoHolder.setRotation(90); 
     MediaController mediaController = new MediaController(context); 
     videoHolder.setMediaController(mediaController); 
     mediaController.setAnchorView(videoHolder); 
     videoHolder.requestFocus(); 
     if(autoplay) { 
      videoHolder.start(); 
     } 
     videoHolder.setOnCompletionListener(new OnCompletionListener() { 

      @Override 
      public void onCompletion(MediaPlayer mp) { 
       dialog.dismiss(); 

      } 
     }); 
     return dialog; 
    } 


    /** 
    * Creates a simple dialog box with as many buttons as you want 
    * @param context The context of the dialog 
    * @param cancelable whether the dialog can be closed/cancelled by the user 
    * @param layoutResID the resource id of the layout you want within the dialog 
    * 
    * @return the dialog 
    */ 
    public static Dialog getBaseDialog(Context context, boolean cancelable, int layoutResID) { 
     Dialog dialog = new Dialog(context, R.style.Theme_PopUpDialog); 
     dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); 
     dialog.setCancelable(cancelable); 
     dialog.setCanceledOnTouchOutside(cancelable); 
     dialog.setContentView(layoutResID); 

     return dialog; 
    } 
} 

在

所以我Activity我只是有這個創造我的對話框：

Dialog videoDialog = DialogHelper.getVideoDialog(context, Uri.parse("http://commonsware.com/misc/test2.3gp"), true); 
videoDialog.show();

我建議你需要使用Activity而不是Dialog。將您的Activity主題設置爲在清單中模擬Dialog。

例 - 的AndroidManifest.xml：

android:theme="@android:style/Theme.Dialog" 

然後，將能夠顯示VideoView如實施例中。

這對我來說

在XML佈局工作作出這樣的改變，

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" > 

    <VideoView 
     android:id="@+id/videoview" 
     android:layout_width="640dp" 
     android:layout_height="400dp" 
     android:layout_centerInParent="true" > 
    </VideoView> 

     <FrameLayout 
      android:id="@+id/videoViewWrapper" 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 
      android:layout_alignParentBottom="true" > 
     </FrameLayout> 

    </RelativeLayout> 

在dilog，

mVideoView = (VideoView) view.findViewById(R.id.videoview); 

在此

，錄像查看使用setOnPreparedListener監聽器，並設置媒體控制器，

mVideoView.setOnPreparedListener(new OnPreparedListener() { 

       @Override 
       public void onPrepared(MediaPlayer mp) { 
        // TODO Auto-generated method stub 
        mp.setOnVideoSizeChangedListener(new OnVideoSizeChangedListener() { 
         @Override 
         public void onVideoSizeChanged(MediaPlayer mp, 
           int width, int height) { 
          /* 
          * add media controller 
          */ 
          mc = new MediaController(MainActivity.this); 
          mVideoView.setMediaController(mc); 
          /* 
          * and set its position on screen 
          */ 
          mc.setAnchorView(mVideoView); 

          ((ViewGroup) mc.getParent()).removeView(mc); 

          ((FrameLayout) findViewById(R.id.videoViewWrapper)) 
            .addView(mc); 
          mc.setVisibility(View.VISIBLE); 
         } 
        }); 
        mVideoView.start(); 
       } 
      });
