Suppose I have a listview with 3 rows. If the user clicks a button in row 1, it expands a menu (it's just a linear layout that's shown/hidden). If they then click on an item in row 2, I'd like to be able to collapse the menu in row 1. Is this possible? If so, how? ...

Hi everyone ! I think I might be about to ask a dummy question, but I'm still new with Android programming, and I couldn't (despite all my efforts) find my answer on Google. The thing is, I'm trying to develop a little game, with 2D Graphics. I want my "gaming board" to be at a specific position on my screen, so that I can display in-g...
Hello all. I'm working on a research project which involves Bluetooth and the Android OS. I need to make Bluetooth discoverable indefinitely in order for the project to continue.

I would like it to be con...
I have a TableLayout with a tableRow and a horizontal scroll view in the 2nd column, but the right side always gets cut off. IF i have only 1 tableRow, it works, otherwise it goes past the visible area of the screen. To simply and isolate the problem heres an xml file with the guilty culprits. It seems basic but i have been super frustra...
In my application, I currently have several activities that consist of a TextView and a scrollbar. The only difference between them is the string that the TextView displays. Is there a way to consolidate all of these into one single activity, and depending on how/where the activity is started from, changes the TextView? Perhaps send the ...

I thought I'd have a crack at building an Android app having not done any Java for five years (I've been living in MS land). So my first project was supposed to be something easy. A simple login form that calls a WCF service that I already have from another project. So I got the whole thing set up OK in Eclipse and the app is running ...
Hi... By default, when in DialogPreference you press BACK button, it mimics that you've pressed NegativeButton. I'd like to override that but can't find an easy way except to recreate DialogPreference from scratch (which at the moment seems like an overkill), because I'd like that PositiveButton SET something, NegativeButton to UNSET s...
In my android app, is there any way to get the total amount of memory my application is taking up, in the code. I'm using lots of large bitmaps, so it must include external allocations as well. I must, however, be able to get the number in the code, so that I can dynamically adjust to fit the budget I have. I also need a way to get the ...
