GridView崩溃在android api级别14上，虽然清单设置为api 11并且上升了

我正在测试我的应用程序。它适用于我的三星Galaxy S5和Android 4.1.2我的LG。但是当我尝试在LG 4.0.4（真实设备）或Nexus 5的模拟器上测试它时，由于以下堆栈跟踪而崩溃。我的清单设置为最小sdk 11.在堆栈跟踪下面，我也显示了我的GridView代码。感谢任何帮助解决这个问题。GridView崩溃在android api级别14上，虽然清单设置为api 11并且上升了

的GridView

除了一般的findViewById，在包含GridView中活动的唯一特定代码

myGridView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() { 
      @SuppressLint("NewApi") 
      @Override 
      public void onGlobalLayout() { 
       if (myGridViewAdapter.getNumColumns() == 0) { 
        final int numColumns = 2; 
        if (numColumns > 0) { 
         final int columnWidth = myGridView.getWidth()/numColumns;// - mImageThumbSpacing; 
         myGridViewAdapter.setNumColumns(numColumns); 
         myGridViewAdapter.setItemHeight(columnWidth); 
         if (BuildConfig.DEBUG) { 
          Log.d(TAG, "onCreateView - numColumns set to " + numColumns); 
         } 
         if (Utils.hasJellyBean()) { 
          myGridView.getViewTreeObserver().removeOnGlobalLayoutListener(this); 
         } else { 
          myGridView.getViewTreeObserver().removeGlobalOnLayoutListener(this); 
         } 
        } 
       } 
      } 
     });

然后在适配器内部在方法getView中，我有这个sn ippet

public View getView(int position, View convertView, ViewGroup parent) { 

     // First check if this is the top row 
     if (position < mNumColumns) { 
      if (convertView == null) { 
       convertView = new View(mContext); 
      } 
      // Set empty view with height of ActionBar 
      convertView 
       .setLayoutParams(new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, mActionBarHeight)); 
      return convertView; 
     }

的例外，你复制的代码是不是映射。您可以在发布之前发布您的活动，适配器和xml，然后进行清理和构建 – 2014-10-22 02:29:29

尝试

convertView.setLayoutParams(new AbsListView.LayoutParams(AbsListView.LayoutParams.MATCH_PARENT, mActionBarHeight));
