问题 In my activity i have created seven listviews and am using viewpager to swipe between them in the same activity. I then have a sqlite database populating each listview. My problem is the onitemclicklistener is not working, there are no errors and the code executes fine but nothing happens on list item clicks. I tested it out by adding toast display messages etc but nothing happens on list item clicks. I suspect the problem is i have not gotten the listviews from xml layouts like the

问题 In my app, I show data in a list view. It looks as below. Each row in list view is different (ie., they have a different view structure).

问题 I am currently having an issue with the creation of my ExpandableListView. I'm unsure what is happening at the moment but I'll explain what I'm trying to do.

Both of which are changed to "Ordered" when a order is made on a meal. If another order is made the previous order button goes back to the 'order' state and the selected one goes to

问题 I tried to implement FloatingGroupExpandableListView but I was unable to modify it according to my custom listview. The below code implements 2 types of headers in the list.

问题 I am using PullToRefresh ListView from chrisbanes which I found here. I implemented it successfully, thanks to its documentations. :) However, I am stuck at this one point now. I am using volley to get the data from the server. It works perfectly till I added a check to see if theres no more data then simply Toast the user. I did like below, @Override public void onRefresh( PullToRefreshBase<ListView> refreshView) { if (hasMoreData()){ //Call service when pulled to refresh orderService(); }
