如何以編程方式修改videoview的寬度

我在我的活動中創建了視頻視圖，當活動開始時，我想修改視頻的高度和寬度。怎麼做？如何以編程方式修改videoview的寬度

這是我的代碼。我試圖用簡單的佈局PARAMS和FRAM佈局沒有什麼工作對我來說

  final VideoView vvVideos = (VideoView) rootView.findViewById(R.id.videoView); 
      MediaController mediacontroller = new MediaController(ctx); 
     mediacontroller.setAnchorView(vvVideos); 
     String videoFileName = videos.get(position); 
      Uri video = Uri.parse("android.resource://" + packageName +"/"+R.raw.sample); 
      vvVideos.setMediaController(mediacontroller); 
      //LayoutParams lp = new LayoutParams(LayoutParams.MATCH_PARENT,150); 
      vvVideos.setLayoutParams(new FrameLayout.LayoutParams(LayoutParams.MATCH_PARENT,150)); 
      vvVideos.setVideoURI(video); 
      vvVideos.requestFocus(); 
      vvVideos.setOnPreparedListener(new OnPreparedListener() { 
       // Close the progress bar and play the video 
       public void onPrepared(MediaPlayer mp) { 
        //pDialog.dismiss(); 
        vvVideos.start(); 
       } 
      });

解決方案

此代碼對我的作品....

  LayoutParams params=vvVideos.getLayoutParams(); 
      params.height=150; 
      vvVideos.setLayoutParams(params);

您是否嘗試過通過getHolder（）設置尺寸？setFixedSize（screenWidth，screenHeight）; – Harish

試試這個，它爲我工作

VideoView video=(VideoView) findViewById(R.id.videoView1); 
     video.setVideoURI(setVideoUri()); 
     video.setVisibility(View.VISIBLE); 
     RelativeLayout.LayoutParams layoutParams = (RelativeLayout.LayoutParams)video.getLayoutParams(); 
     layoutParams.addRule(RelativeLayout.ALIGN_PARENT_LEFT, 0); 
     layoutParams.addRule(RelativeLayout.CENTER_IN_PARENT, 0); 
     video.setLayoutParams(layoutParams);

VideoView videoview=(VideoView) findViewById(R.id.videoView1); 
videoview.setVideoURI("yourURI"); 
videoview.setLayoutParams(new FrameLayout.LayoutParams(550,550)); 

LinearLayout linearLayout = (LinearLayout)findViewById(R.id.info) 
linearLayout.addView(videoview);

出現錯誤，說明視頻已經出現在視圖 – Vignesh

中，哪一行出現錯誤。 – Riser

linearLayout.addView（videoview）;.現在它爲我工作，我已經在問題中添加了解決方案.... – Vignesh
