OnClick在编辑toastview时崩溃，并返回

Question

我试图将已经在XML中的RelativeLayout添加到我的Toast视图中。这不是我的主要UI线程。

@Override 
     public void onClick(View v) 
     { 
      mContext.setContentView(R.layout.toast_layout); 
      Drawable myImage; 

      Toast imageToast = new Toast(mContext); 

      final RelativeLayout toastLayout = (RelativeLayout) mContext.findViewById(R.id.relative_toast); 
      final ImageView myIv = (ImageView)toastLayout.findViewById(R.id.tImage); 
      final TextView nameText = (TextView)toastLayout.findViewById(R.id.tFriendName); 
      final TextView interestText = (TextView)toastLayout.findViewById(R.id.tInterests); 

      myImage = getImageDrawable(mContext, friend.getmPic(), "image.jpg"); 

      myIv.setImageDrawable(myImage); 

      nameText.setText("Name: " + friend.getmName() + 
          "\nID: " + friend.getmId()); 
      nameText.setPadding(10, 0, 0, 5); 
      nameText.setTextColor(Color.BLACK); 

      interestText.setText("Interests: " + friend.getmInterests()); 
      interestText.setTextColor(Color.BLACK); 

      toastLayout.setBackgroundColor(Color.LTGRAY); 
      toastLayout.setMinimumHeight(400); 
      toastLayout.setMinimumWidth(250); 
      toastLayout.setPadding(10, 10, 10, 10); 

      imageToast.setView(toastLayout); 
      imageToast.setDuration(Toast.LENGTH_LONG); 
      imageToast.show(); 
     } 

当我从此范围返回时，调试显示它崩溃。

的logcat：

，如果你试图让一个自定义的敬酒布局，您应该保存在自己的资源的XML文件的布局的XML（即toast_layout.xml） 那么你上面应该

LayoutInflater inflater = getLayoutInflater(); 
    View layout = inflater.inflate(R.layout.toast_layout, 
      (ViewGroup) findViewById(R.id.toast_layout_root)); 

其中toast_layout_root是上述toast_layout.xml

的根元素然后

toast.setView(layout);
