ScrollView嵌套listview 时根据内容动态设置listview高度

 public static void setListViewHeightBasedOnChilds(ListView listView){
        ListAdapter listAdapter = listView.getAdapter();
        if(listAdapter==null){
            return;
        }
        int totalHeight=0;
        int totalDividerHeight=0;
        for(int i = 0;i<listAdapter.getCount();i++){
            View listItem=listAdapter.getView(i, null, listView);
            listItem.measure(0,0);
            totalHeight+=listItem.getMeasuredHeight();
        }
        totalDividerHeight=listView.getDividerHeight()*(listAdapter.getCount()-1);
        ViewGroup.LayoutParams params=listView.getLayoutParams();
        params.height=totalHeight+totalDividerHeight;
        listView.setLayoutParams(params);
    }
