Android ListView与ScrollView冲突的解决方法总结

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