android ListView 嵌套scrollView 自适应高度

很多时候我们的需求要求我们在scrollView里面嵌套ListView，但是直接嵌套的话，ListView只会显示一个Item,这时候就需要ListView根据Item的数量来自适应高度了。

// 设置ListView高度
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);
}
