问题 In my app I have a listview, which when you click on an item i want a dialogfragment to appear with details in it. The listview is populated using a custom cursoradapter and each row is a view extended from a relativelayout. My thought process is that i would have some kind of id value in the custom view and when selected, the id is used in a new db query to populate the dialogfragment. However, I don't want the id on view in the row, I want it hidden. I'm thinking that i create a custom view

问题 I've been looking into ways to show data from my DB in a ListView while keeping track of changes in the database. Let's say I have a chat app that shows a ListView of all the chatrooms I am a member of. the query for the adapter is SELECT * FROM CHAT_ROOM ORDER BY UPTDATE_TIME , meaning I want the chatrooms with recent activity to be shown first. as I am in the ChatroomListActivity a message is received for chatroom number 3, this means it needs to become now chatroom number one and rearrange

问题 I'm having troubles with my Custom CursorAdapter and my ListView , the fact is, I can save data in my sqlite Database in my custom ContentProvider but my ListView is not populated. I know DB Operations are heavy long operations, therefore I do it in another thread and furthermore CursorLoader is a subclass of AsyncTaskLoader , so it should be prepared for that. With SimpleCursorAdapter works fine but with this Custom CursorAdapter not. Can anyone tell me what is wrong and how could I solve it

问题 I have never been happy with the code on my custom CursorAdapter until today I decided to review it and fix a little problem that was bothering me for a long time (interestingly enough, none of the users of my app ever reported such a problem). Here's a small description of my question: My custom CursorAdapter overrides newView() and bindView() instead of getView() as most examples I see. I use the ViewHolder pattern between these 2 methods. But my main issue was with the custom layout I'm
