ScrollView和ListView的冲突问题

在ScrollView添加一个ListView会导致listview控件显示不全，这是因为两个控件的滚动事件冲突导致。所以需要通过listview中的item数量去计算listview的显示高度，从而使其完整展示，如下提供一个方法供大家参考。

示例代码：

public 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));
params.height += 5;//if without this statement,the listview will be a little short
listView.setLayoutParams(params);
}
