我的GridView

 ＆LT; GridView中的xmlns：机器人=htt​​p://schemas.android.com/apk/res/android
                机器人：ID =@ + ID / new_small_list
                机器人：layout_width =FILL_PARENT
                机器人：layout_height =WRAP_CONTENT
                机器人：为numColumns =2
                机器人：verticalSpacing =3DP
                机器人：horizo​​ntalSpacing =3DP
                机器人：stretchMode =columnWidth中
                机器人：重力=中心
                机器人：cacheColorHint =@机器人：彩色/透明
            /＆GT;
 

解决方案

有关设置单元格的高度，在GridViewAdapter当你写，例如：

  @覆盖
公共查看getView（INT位置，查看convertView，ViewGroup中父）{

        如果（convertView == NULL）{

            LayoutInflater cellLayout =（LayoutInflater）getSystemService（Context.LAYOUT_INFLATER_SERVICE）;
            convertView = cellLayout.inflate（R.layout.gridcell_layout，NULL）;
        }

        TextView的cell_title =（TextView中）convertView.findViewById（R.id.gridview_cell_text）;
        ImageView的cell_icon =（ImageView的）convertView.findViewById（R.id.griview_cell_image）;
        ....
 

刚刚替补这一行：

  convertView = cellLayout.inflate（R.layout.gridcell_layout，NULL）;
 

通过这样的：

  convertView = cellLayout.inflate（R.layout.gridcell_layout，GridView控件，FALSE）;
 

通过这种方式，设置家长参考的膨胀，宽，高约电池将设置！ 在这里你可以找到原因：

i have simple gridview. it's elements have different height. for example in row there are one small element and one bigger, next row will align to smaller element and a part of bigger element is under the second row. how can i set the height of each row of gridview to be the height of the biggest element in row??

my gridview

<GridView xmlns:android="http://schemas.android.com/apk/res/android" 
                android:id="@+id/new_small_list"
                android:layout_width="fill_parent" 
                android:layout_height="wrap_content"
                android:numColumns="2"
                android:verticalSpacing="3dp"
                android:horizontalSpacing="3dp"
                android:stretchMode="columnWidth"
                android:gravity="center"
                android:cacheColorHint="@android:color/transparent"
            />

解决方案

For setting cell height, in GridViewAdapter when you write, for example:

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

        if(convertView == null){

            LayoutInflater cellLayout = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);             
            convertView = cellLayout.inflate(R.layout.gridcell_layout, null);
        }

        TextView cell_title = (TextView) convertView.findViewById(R.id.gridview_cell_text);         
        ImageView cell_icon = (ImageView) convertView.findViewById(R.id.griview_cell_image);
        ....

Just substitute this line:

convertView = cellLayout.inflate(R.layout.gridcell_layout, null);

With this:

convertView = cellLayout.inflate(R.layout.gridcell_layout, gridView, false);

By this way, setting parent reference in "inflate", Width and Height about cell will set! Here you can find why:
