Android :: How To Copy A Smaller Bitmap Into A Larger One
Mar 1, 2010
I'm trying to copy a series of small bitmaps into a larger one, arranging them side by side without any gaps or overlap in their pixels. For example, if I have 3 square bitmaps, I'd like to copy them into one long and thin rectangle. I know how to do the opposite, namely creating a small bitmap out of a larger one, but not this way around. What's the right command? I want to do this to be able to reuse some code I wrote for handling animation with a single bitmap.)

if size of image is larger than or smaller than specified display size (on screen), then it is automatically, compressed and stretched resp by android run time or require to handle by explicitly.

when i am composing a text message, sometimes the box of the entry goes larger and goes back smaller, is there a way to increase the text entry box size, say, double tap on it to bring up a whole screen text entry area?

In 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.

I have a very large image and I only want to display a section the size of the display (no scaling), and the section should just be the center of the image. Because the image is very large I cannot read the entire image into memory and then crop it. This is what I have so far but it will give OutOfMemory for large images. Also I don't think inSampleSize applies because I want to crop the image, not lower the resolution.
Uri data = getIntent().getData();
Input Stream is = getContentResolver().openInputStream(data);
Bitmap bitmap = BitmapFactory.decodeStream(is, null, null);
Any help would be great?

I am 1) taking a picture and 2) then draw another Bitmap on top of it 3) then I store it
I am doing it as follows and it works on the emulator.
On the device I get a OutOfMemoryError: bitmap size exceeds VM budget android.graphics.Bitmap.nativeCopy(Native Method) android.graphics.Bitmap.copy(Bitmap.java:199) in the line copy the Bitmap to get a mutable Bitmap.
CODE:...........
What I am asking:
a) Is there a better way to do what I am doing? 1) take a picture 2) draw another Bitmap on top of it 3) then I store it
b) What is the best way to create a mutable Bitmap from the picture I just took with the camera?
In my app, resolution is not an issue. If it works better for small photos that would be fine.

I have two questions actually:
Is it better to draw an image on a bitmap or create a bitmap as resource and then draw it over a bitmap? Performance wise... which one is better?
If I want to draw something transparent over a bitmap, how would I go about doing it?
If I want to overlay one transparent bitmap over another, how would I do it?

My goal is the draw a bitmap onto another bitmap but rotated 90 degress. whats the most efficient way to do that. My current method is as follows which is horribly bad because it creates a new bitmap every time.

I am trying to create smaller tabs in android -- but I can't seem to get it to work because all that happens when I create a smaller tab is that it shows the bigger tab -- but without a drawable.
This is my layout code for tabs now -- but the height isn't wrapping for some reason -- it just goes to Android's usual layout height.
CODE:.........................
It would be great if someone could help me create something like the Facebook application -- I think that looks really clean and I would love to implement something like it:

I've added a RatingBar in a layout :
CODE:...........
But the default style for the rating bar is too large.
I've trie to change it by adding the android style : style="?android:attr/ratingBarStyleSmall"
But the result is too small and it's impossible to set a rate with this property.

It has come to my attention that Android can only deal with asset files that are around 1M or so. My problem is that i'm creating an app that requires access to 5 csv files. The largest of the files is 130M. I want to be able to package these text files with my app. Is there anyway around this? My app needs to be able to run without Internet access so storing these files on a server is not an option.

Brand new to android, and loving it. But with the release of the Audible app and various music files, I'm going to fill my little 2GB card soon.
How would I go about switching to a larger capacity card? I'm not worried about data files, I know I can copy all of that stuff off the card, but what about any apps or app settings that might be stored on the card? If I simply copy the entire contents of the card to a new one, will everything "work" when I start the phone up? I confess I don't really know much about the android guts, but I'm willing to learn!
Phone specs:
1.) Model Number: Samsung Intercept SPH-M910
2.) Firmware Version: 2.1-update1
3.) Baseband Version: S:M910.05 S.DF27
4.) Kernel Version 2.6.29
5.) Build Number Samsung ECLAIR.DF27
6.) Carrier - Sprint
7.) US

Any apps that will make everything larger on the screen in Android?
I have found something that makes the fonts bigger but what about the rest of the stuff including icons, address book and so on?
I need to be able to see the stuff on the screen.
IF I have a choice, should I go android or windows and why should I chose one over the other?

I have an application built for 1.5 and I am adding higher resolution drawables to support hdpi devices in 1.6 and above.My original application icon is 48x48. I created a second launcher icon that is 72x72 and placed it in a res/drawable-hdpi/ directory.When I install the application on my Nexus One the icon looks good when I view it in the application menu.But when I place it on the desktop it appears small relative to other icons, my guess is I'm seeing the 48x48 version with no scaling.Do I need to do something differently either with my directory structure or my manifest file to get things to display correctly?

I need to show a large number of EditText controls on a screen, each of which will only allow entering 0-2 digits. The default EditText size is too wide for me to show enough EditText controls on a screen, but I have been unable to figure out how to make them narrower. I have tried the following attributes in XML: android:maxLength="2" android:layout_width="20dip" android:maxWidth="20px" android:ems="2" android:maxEms="2". So the question is: how can EditText be made smaller than default?

I want to create an application that uses small tabs, such as the one the Android's facebook official app uses. Does anyone know how these kind of tabs can be created? Do I need to extend the TabHost class in order to customize it, or is there a more general easier approach?

I am creating a simple android app to view a comic book. The pages are large(0.5-1 mb each), high quality .png's and I am loading them into a webview to make use of the built in zoom controls. So far I only have 17 files and the APK size is already about 16 mb. I'm looking to add over 200 files in future updates. I can't really reduce the quality too much because there is small text that must be zoomed-in on to read. Any suggestions? A similar question was posted here: How to reduce App (.apk) Size, but I don't want to lose the quality of the images. I'm not sure if it's appropriate to link to here, but you can have a look at my app by searching for Tracer (by Detour Mobile) on the android market if it helps at all.

I have a basic linear layout, with image view that display photos, textviews that show text etc...and when I test my whole app on my android 2, there is never any part of the screen that doesn't show. But when I test it in the QVGA emulator, half the view is off the screen. Now, some of my text is defined to a certain size.
I never use px (only dip) in any of my xml. I use fill_parent, wrap_content where it is needed and never fix a height or length. Could it be with my text, I use say, textSize = 22dip? I couldn't find documentation on why that would not work in all sizes. Could it be that some apps need to be programmed to those screen sizes? Or am I missing something?

I use a few small images on my app and I was wondering if (and how) I could ensure that the size of the image is relative to the size of the phone? Also, is there a way to shrink my layout on smaller phones so each layout fits within the screen - like if a random string (longer than others) would downsize in font so the whole layout was ensured to fit on the screen?

Is there an app or widget that can be used to make a larger button? I'd prefer a 2x2 size that I can use to direct dial while driving rather than having to fiddle with the small 1x1 size, but anything bigger than the standard would be fine.
I've only found apps that make smaller buttons and one that makes me select subsequent options before I can actually call. I just want a large single press widget.

I've been playing around with the Vignette demo version for a couple of days and I'm having an issue that I hope is just related to this being the free version. I know that the free version of Vignette only saves pictures at the really small size. When I take a picture through the app and save a square version of it, it's saving at 540 by 540 pixels. When I open the app and import another picture I've taken with the phone and use exactly the same effects, I get a 275 by 275 pixel square. I'm thinking of buying the full version, will the pictures I import and process always turn out smaller than the ones I take with the camera?

I have an application that works fine with smaller images (say 1024x768 or so) but when you rotate the phone into a different orientation (say landscape to portrait) mode with a larger image on the screen, and then call ImageView.setImageUri() it goes into the BitmapFactory.class and never returns.So the app eventually times out. Never throws an exception, just never returns. Has anyone else seen this? Sounds like a bug in the Android code more than something I am doing since it works fine for smaller images.
