Notifydatasetchanged Working But Only Showing 1 Result In Listview Android

Hi i have an issue where only 1 result is being shown when i call a notifydataSetChanged function. I have read in this forum that the Array list needs to be cleared, then the data

Solution 1:

What's probably happening is that your list sentMessages is what you used to initialize your MessageAdapter, correct? By calling mList.clear() since it points to the same object as sentMessages, you are clearing everything from both lists (which is really just the exact same list). What I would do is change your MessageAdapter constructor to the following:

public MessageAdapter(Activity context, ArrayList<ArrayList<ReadMessage>> list) {
    mContext = context;
    mList = new ArrayList<ArrayList<ReadMessage>>();
    mList.addAll(list);
    mLayoutInflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
