ScrollView和ListView一起使用的问题

1.第一种方法只能实用单个的listview。第二个是适合ScrollView嵌套listview，然后listview中还可以包含GridView 但是必须自定义listview或则是GridView

public static int setListViewHeightBasedOnChildren(ListView listView){

int scrollViewHight = 0;

int totalHight = 0;

ListAdapter listAdapter = listView.getAdapter();

if(listAdapter == null){

return 0;

}

for(int i = 0; i < listAdapter.getCount(); i++){

View itemView = listAdapter.getView(i, null, listView);

itemView.measure(0, 0);

totalHight += itemView.getMeasuredHeight();

}

ViewGroup.LayoutParams params = listView.getLayoutParams();

scrollViewHight = totalHight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));

params.height = scrollViewHight;

listView.setLayoutParams(params);

return scrollViewHight;

}

2.首先，ListView不能直接用，要自定义一个，然后重写onMeasure（）方法：

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,
MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, expandSpec);
}
