ScrollView中嵌套ListView时显示不全的解决方案

public class Utility {
public static void setListViewHeightBasedOnChildren(ListView listView) {
//获取ListView对应的Adapter
ListAdapter listAdapter = listView.getAdapter();
if (listAdapter == null) {
// pre-condition
return;
}

int totalHeight = 0;
for (int i = 0, len = listAdapter.getCount(); i < len; i++) {   //listAdapter.getCount()返回数据项的数目
View listItem = listAdapter.getView(i, null, listView);
listItem.measure(0, 0);  //计算子项View 的宽高
totalHeight += listItem.getMeasuredHeight();  //统计所有子项的总高度
}

ViewGroup.LayoutParams params = listView.getLayoutParams();
params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
//listView.getDividerHeight()获取子项间分隔符占用的高度
//params.height最后得到整个ListView完整显示需要的高度
listView.setLayoutParams(params);
}

}
