it works can some one explain to me what's wrong ?
As far as I have read in the Internet and official documentation, it isn't possible to make a scrollable app widget. Also all my tries failed. I even tried to subclass TextView to implement my own scroll method, but nothing worked.Are there any ways to achieve that? there are solutions if you use for example htc sense or home desktop ++, but i want to make it available to other users which don't use this

View 1 Replies View Relatedis it possible to make an entire linear layout scrollable when it needs to be? (when all of the elements in the layout don't fit on the main screen)?I know it is doable with views, etc.but is there a way to incorporate everything on the layout to be scrollable at the same time?Maybe scrollable is not the right term. basically - if one of the elements (a button in this case) doesn't entirely make it onto the main screen of the phone and I need to slide a finger down to access it if that makes sense.

View 2 Replies View RelatedI'm fairly new to android programming and I'm writing a simple app that performs some math calculations. I'm having the user enter some information in a couple edittexts. When the keyboard pops up though, it covers the submit button on the bottom. I can make the entire layout scrollable, but then you can scroll too far. How do I make it so that, when the keyboard is up, you can scroll down to see other information (like buttons, textviews, etc)?

I'd like to know how to make a button out of a PNG and display it on my canvas (using drawBitmap?). When I click on this button, it will take me to a new activity. All this will be in the onClickListener. So, how do I take a PNG, make a button with it, and draw it on my canvas? I looked at ImageButton, but I'm unsure how it works or how to draw it on the canvas.

View 1 Replies View RelatedI 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 2 Replies View RelatedI have an image of a map. I want to draw lines over that image.I have successfully displayed both the line and the image. But , the line is not transparently appearing over the image. The image is only displayed when i run the program. But,if i change the coordinates of the line so that it doesn't overlap with the image,the line is getting displayed.
Pls tell me what i should do to make the line transparent so that both the image and the line are getting displayed.
My app, among other things, downloads and displays images from the Internet. Some might be too large and trigge an OOM when ImageView.setImage() is called. Of course, this normally makes the application to crash. I've put catch (OutOfMemoryError e) around the method invocation. I know that catching errors is unusual, but in JSE applications it proved to work pretty good, especially when the problem was due to image manipulation that consumed all the memory. The Android app seemed to survive for a while, but then it blocked the computer. All buttons are irresponsive, even though the phone seems still alive (e.g. it's playing the audio notification that new email has been spotted). I tried holding the power button, it triggered the shut down menu, but touching a menu option didn't do anything. Only after a while, the phone became responsive again.
Now, it's reasonable that one can't display everything on a smartphone; I'm sure there's some inefficient memory management I'm doing (perhaps keeping too many images in memory); ok, I have to improve my code. Given that I'll do, how can I add some safety facility to avoid the most severe consequences? Making an irresponsive application it's a 100% sure way to make people to uninstall my app and give bad reviews. I'm thinking of a two-pronged safety approach: 1) whether it's possible to understand in advance whether an image is too large to be rendered by itself;
2) whether it's possible to recover from an OOM in any case.

View 2 Replies View RelatedI'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.

I am having a PNG file with Alpha channel in it. I want to turn the touched pixels to transparent so that, the user can feel that he is actually erasing it.
