scrollview嵌套listview时 动态设置listview高度

public class GetListViewHeight {

public static void setListViewHeightBasedOnChildren(ListView listView) {

ListAdapter listAdapter = listView.getAdapter();

if (listAdapter == null) {

// pre-condition

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);

}

}

调用的时候

new GetListViewHeight().setListViewHeightBasedOnChildren(ListView_Name);
