写了一个Layout文件,最外层是一个 ScrollView ,其中包含了两个 ListView 和其他的组件。
但运行时发现 :只展示了 listview 的 index = 0 的view
<ListView
android:id="@+id/vedioUrlListView"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:divider="@null"></ListView>
The vertically scrolling ScrollView should not contain another vertically scrolling widget (ListView)
解决方法:在 代码中重新 遍历 listview 的子 ,根据子的高度值,重新设置一下 listview 的高度值。
vedioListView.setAdapter(vedioUrlAdapter);
setListViewHeightBasedOnChildren(vedioListView);
public void setListViewHeightBasedOnChildren(ListView listView) {
// get the list view adapter, so this function must be invoked after set the adapter.
BaseAdapter listAdapter = (BaseAdapter) listView.getAdapter();
if (listAdapter == null) {
return;
}
int totalHeight = 0;
// get the ListView count
int count = listAdapter.getCount();
for (int i = 0; i < count; i++) {
View listItem = listAdapter.getView(i, null, listView);
// measure the child view
listItem.measure(0, 0);
// calculate the total height of items
totalHeight += listItem.getMeasuredHeight();
}
ViewGroup.LayoutParams params = listView.getLayoutParams();
// get divider height for all items and add the total height
params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
listView.setLayoutParams(params);
}
测试成功。
