ListView的 Header嵌套GridView有关问题
ListView的 Header嵌套GridView，GridView显示比较大的图宽度设为match_panrent，高度设为固定值图片都能正常显示，但是图片大小高度不一样，我想设为wrap_content，这时图片就不能正常显示，已经自定义gridview
public class GridViewForListView extends GridView {
public GridViewForListView(Context context) {
super(context);
}
public GridViewForListView(Context context, AttributeSet attrs) {
super(context, attrs);
}
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,
MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, expandSpec);
}
}

使用如下方法动态计算试试：
/**
* 动态计算gridView高度
*
* @param gridView
* @param colums
* 固定的列数
*/
public static void setgridViewHeightBasedOnChildren(Context context,
GridView gridView, int colums,boolean isHight) {
ListAdapter listAdapter = gridView.getAdapter();
if (listAdapter == null) {
return;
}
int totalHeight = 0;
for (int i = 0; i < listAdapter.getCount(); i += colums) {
View listItem = listAdapter.getView(i, null, gridView);
listItem.measure(0, 0);
totalHeight += listItem.getMeasuredHeight();
}
ViewGroup.LayoutParams params = gridView.getLayoutParams();
params.height = totalHeight + (5 * (gridView.getCount() - 1));
if(isHight){
params.height = params.height + gridView.getRowHeight();
}
gridView.setLayoutParams(params);
}
