View 1 Replies View RelatedI have a ListView that with alphabetical headers for each letter. I also have an index function that brings the letter headers to the top of the screen.
My problem is when I reach the end of the list setSelection is unable to bring the last few headers to the top because it will not scroll past the end of the list.
My question is this: Is there a way to add a blank space to the end of the screen dependent on screen size? I would like to scroll until the last item in the list is at the top of the listView.

I've had the Evo since the release day and I loved it, greatest phone ever in my opinion. Well about two weeks ago, something happened and it broke, yeah it was my fault but i'd rather not talk about it. So I decided to upgrade to the Epic 4G, I found one and bought one last week. I immediately fell in love with that phone. Now here's the worst part, the same day I buy the phone it breaks. I accidentally dropped it from a height of around 1 feet onto my sink. The inner screen shatters but the outside glass is perfectly fine. I couldn't believe it. I believe that the new Super AMOLED screen is very fragile because I've dropped the Evo hundreds of times and nothing ever happened. I then decided to switch back to the Evo and ordered a replacement phone after a difficult process. Yesterday, I received the replacement Evo. Well I immediately notice it's refurbished and it doesn't seem to bother me. It turns on fine the first time and I proceed to activate it. First, the touch screen is not working at all. Only a few sections of the screen work even after full resets and calibrations. The phone then dies and never turns on ever again, I've tried different batteries and chargers but no luck.

View 10 Replies View RelatedI have a single screen with a bank of buttons below a ListView. Entries on the ListView light up in orange when I scroll so I assume that are selected. When I then press the "Delete" button I want the onClickListener to remove the currently selected entry. But getSelectedItemPosition() always gives me -1. If I can't hope to use the GUI controls in this way, please give me another way of getting the same result.I have even tried setting the onClickListener of the List View to store the index before the button is pressed (in case pressing the button unselects the entry) but even that is always -1 it seems.

The following code leads to "java.lang.IllegalThreadStateException: Thread already started." the second time it is run through on the program This happens the second time updateUI.start() is called. I've stepped through it multiple times and the thread is called and completely runs to completion before hitting updateUI.start(). Calling updateUI.run() avoids the error but causes the thread to run in the UI thread (the calling thread, as mentioned in other posts on SO), which is not what I want. Can a Thread be started only once? If so than what do I do if I want to run the thread again? This particular thread is doing some calculation in the background, if I don't do it in the thread than it's done in the UI thread and the user has an unreasonably long wait.
