I have a layout which has two ListViews and they are all inside a scrollview because the contents can exceed the device's height. Here is the layout:

The two listviews have id listView2 and listView6. I have set up the adapters for both the listview properly. I am getting the data from backend. For both the listviews, I am getting two items from backend but actually it is showing just one item in each listView. I am also trying to add item to second listView, using notifyDataSetChanged() but that is not working too. I am getting only one item. What could be the possible reason and how to fix it?
Here is what I did, in case someone else is having similar problem:
Note: This solution is very inefficient. I am using it because I have at max 2 items in my listView. I would not recommend it to others if you have a listView that has some significant number of items.
public static void setListViewHeightBasedOnChildren(ListView listView) {
ListAdapter listAdapter = listView.getAdapter();
if (listAdapter == null) {
// pre-condition
return;
}
int totalHeight = listView.getPaddingTop() + listView.getPaddingBottom();
for (int i = 0; i < listAdapter.getCount(); i++) {
View listItem = listAdapter.getView(i, null, listView);
if (listItem instanceof ViewGroup) {
listItem.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
}
listItem.measure(0, 0);
totalHeight += listItem.getMeasuredHeight();
}
ViewGroup.LayoutParams params = listView.getLayoutParams();
params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
listView.setLayoutParams(params);
}
I called this function on both listViews after setting up the adapter. Hope it helps.
