Mar 13, 2010I've determined an estimate of the size of my Android emulator's screen in pixels, although I think its resolution can be changed to other numbers. Quite frankly though that doesn't eliminate the general problem of not knowing how many pixels on each axis I have to work with on my Android applications in general.The main problem I'm trying to solve is this: How do I make sure I don't use a faulty resolution on Android applications if I want to keep things' sizes constant (so that if the application screen shrinks, for instances, objects will still show up just as big - there just won't be as many of them being shown) if I wish to do this with a single universal resolution for each program? Failing that, how do I make sure everything's alright if I try to do everything the same way with maybe a few different pre-set resolutions?
Mainly it seems like a relevant question that must be answered before I can come across a complete answer for the general problem is how big can I always make my application in pixels, NOT regarding if and when a user resizes the application's screen to something smaller than the maximum size permitted by the phone and its operating system.I really want to try to keep this simple. If I were doing this for a modern desktop, for instance, I know that if I design the application with a 800x600 canvas, the user can still shrink the application to the point they're not doing themselves any favors, but at least I can basically count on it working right and not being too big for the monitor or something. Is there such a magic resolution for Android, assuming that I'm designing for API levels 3+ (Android 1.5+)?
Android :: Relationship Between Pixels And Scaled Pixels?

Android :: Make Some Part Of An Image Transparent?
Aug 28, 2009I have a scenario at hand, for which I need a solution as soons as possible. Here is the problem statement: I need to show an image overlapped by some other image, 100%. The condition is that the picture in background should also be visible through the foreground picture but only through some part of the foreground picture. Please try to visualise how it should look like. There is a picture shown and in middle of it, there is a transparent area through which the background image is visible. I knew that I can make an image transparent and make the background image visible but here I want only some part of the foreground image to be transparent so that it looks like sort of picture frame applied to the background puicture. And for those who read the statement carefully would have understood that the ultimate thing desired is to have a picture frame applied to the picture. Can anyone please suggest a good way to do this.

View 1 Replies View RelatedAndroid :: Lunar Lander Make Image Backgrounds Transparent?
Mar 9, 2010I'm trying to make a GUI program with the Android SDK, using their Lunar Lander example as a significant self-teaching tool in the process. I've noticed their sprites' images' backgrounds, which were at least usually pure white, did not show up in their program. I want to ask how they did that, since their site doesn't explain simple things very well. I've managed to pull that off before on another GUI SDK, wherein all I had to do was to call a function and pass it a few floats to define a certain color, and until my code told it to do otherwise, that function would make sure that that particular color in my sprites' images was totally transparent. However I've wrestled with the Lunar Lander example and getting my own program to show some custom graphics for a week or two now, and I haven't noticed any such function call in the Lunar Lander example. I tried to look for it, but I did not find anything. I've tried to Google some tutorial or other reference material, but what I've found so far is just straying off into unrelated areas and totally dodging this EXTREMELY important lesson on the SDK's basics.

Android : Using Bitmap Data To Copy Pixels To A New One
Jan 29, 2010In ActionScript development, there are two classes, Bitmap, and BitmapData. Bitmap uses information from BitmapData to create a Bitmap. Is there an equivalent to BitmapData in the android API? I did some digging and BitmapFactory seems to be the closest, however, I'm facing problems with it.
I tried Bitmap bitmap = BitmapFactory.decode Resource(getResources(), R.drawable.buster);
As that was what I was seeing in most of the examples I came across, but it is telling me that the method getResources is undefined. I'm not really sure what is causing this as in another tutorial I did, getResources didn't cause any problems.
I'm not looking to simply draw a bitmap to the screen, I want to copy a section of the bitmap and place it on a new bitmap. In ActionScript, the method is bitmapData.copyPixels(), and I'm looking for a similar method in the Android API. The closest thing I could find was copyPixelsToBuffer(), but I'm not really sure if that does what I think it does.

View 4 Replies View RelatedAndroid :: In Opengl - Relation Between Pixels And Gl.gltranslatef - Floatx,y,z?
Sep 25, 2010I am trying to learn opengl stuff on Android. In the gl.gltranslatef(x,y,z) call, I am shifting my texture by some units in the +ve x direction. But I am unable to find the number of pixels does 1 unit of x belong to?
Here is what I am doing:
I call gl.glviewport(0,0,width,height); // This will set my rectangle with 0,0 as lowerleft corner and then extend it to accommodate width and height.
Then
I call to gl.glfrustrum(-5,5,-7,7,3,7); // I am little confused how this call is using the dimensions I set in gl.glviewport.
How will -5 to 5 units from left to right in the above call, translate to pixels on the screen of android?
I mean if width = 320 and height = 533 pixels, then what will be the number of pixels occupied on the screen due to the gl.glfrustrum call?
I am experimenting in the gl.gltranslatef call by specifying xshift as 5.0, but it does not translate the bitmap at the right or left corner of the screen, when I increase it to 6, part of it is still visible on the screen.
I am searching for the maximum number of units (in terms of X) which will represent extreme corners of my android phone screen.
Android :: Animate Scroll Of Mapview (by Pixels, Not Lat Long)?
Nov 17, 2010I need to scroll a MapView programatically to make sure something is in view. I know how many pixels it needs to scroll in each direction.

What is an easy way to do this?
Android :: Simplest Way To Draw Pixels Lines / Circles On A View?
Aug 14, 2010What is the simplest way to draw pixels, lines and circles on a View?I want to move a cross cursor around, so nothing particularly intensive.I thought I could extend SurfaceView and add it to an XML and it would just work, but it just appears black, however, when I look at the layout view of localmap.xml in eclipse, the graphics appear as expected. Any ideas? My onDraw is never called on the emulator, and even calling invalidate on the class makes no difference. I shall keep trying but can anyone see anything I've missed? or is there a better way entirely? Code...
