I am kicking around the idea of installing a netbook in my car, and I'd like to write an app (C# and WPF based) that would essentially be a gigantic phone interface connected via bluetooth to my Android phone (Nexus 2.2).

Hi I implemented a gallery, and inside it I have many listviews from left to right. For some reason Gallery works great with all views but not with listview. With listview, when scrolling on the gallery, sometimes I get little jumps. Anyone have an idea on how to solve this? some notes: The gallery uses an adapter to find out what to...

I have a ListView that contains an Image on the left of two vertically-oriented TextViews using a RelativeLayout. When both TextViews have text it looks fine. Sometimes the TextView on the bottom won't have any text, and the problem is that the entire layout is several pixels above where it should be because it still reserves that space ...

Loading three bitmaps takes about 2 or 3 seconds. I'm trying to write an undo engine but I just cannot work out a good way to do it. The typical approaches a...

I'm not sure what it's called exactly, but I was wondering how you can create a class which you can call multiple methods on in one call. For example, using an android class but it doesn't really matter, you can call all of the class' methods at once: AlertDialog.Builder().setItem().setTitle().setPositiveButton().setCancelable() ...etc...
I'm not even concerned with the camera per se. I want at the closest thing to the display screen. Meaning: it could even be the desktop the user is looking at, completw w/ the background and the icons she moves back and forth. Let's say, at time t=1 sec, the app goes to pixel (78, 300) on that display and obtains its value. What m...
Hello, How can I make my simple site, on which the user can choose to play a number of music clips by clicking on little "play" buttons on the page (think of Amazon's "preview" on their product pages for CDs), work on mobile devices? [I originally created the page thinking only of desktop browsers, so currently it works by using Flash...
