Listview in Android Scrollview does not display all items
•
Android
I have a layout containing two listviews, both of which are in the Scrollview, because the content may exceed the height of the device. This is the layout:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

The IDs of these two list views are listview2 and listview6. I have correctly set the adapters for the two listviews. I am getting data from the back end. For these two listviews, I get two items from the back end, but actually only one item is displayed in each listview. I also tried to add the item to the second listview using notifydatasetchanged(), But it doesn't work properly. I only get one item. What may be the reason and how to solve it?
resolvent:
This is what I do in case others encounter similar problems:
Note: this solution is inefficient. I'm using it because my listview contains at most 2 items. If you have a listview with a large number of items, I won't recommend it to others
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);
}
After setting the adapter, I called this function on both listviews. I hope it can help you
