Android :: Give Bitmap Of Symbol Just Another Color?

May 25, 2009

Is there a simple Solution to colorize a Drawable?

I have a PNG with a Symbol (just one Color) on a transparent Background

Now I would need to give the Bitmap of the Symbol just another Color. (think about a green Circle on a alpha Bitmap.. and I wish to make the green circle by a simple Code just Red)

Is there something like that?

Android :: Faster Way To Set A (PNG) Bitmap Color Instead Of Pixel By Pixel

Nov 22, 2010

I have some png files that I am applying a color to. The color changes depending on a user selection. I change the color via 3 RGB values set from another method. The png files are a random shape with full transparency outside the shape. I don't want to modify the transparency, only the RGB value. Currently, I'm setting the RGB values pixel by pixel (see code below).I've come to realize this is incredibly slow and possibly just not efficient enough do in an application. Is there a better way I could do this? Here is what I am currently doing. You can see that the pixel array is enormous for an image that takes up a decent part of the screen

Android : Crop Bitmap Without Reading Entire Bitmap / Cannot Read Image Into Memory

Jul 21, 2010

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?

Android :: Create Mutable Bitmap From Camera - Draw Another Bitmap On Top - And Save It

Apr 2, 2009

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.

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?

Android :: Android Default Color - Primary - Text - Light Is Color Black

May 28, 2009

I got a little textview defined in layout xml:

CODE:.........

As you can see the background color is "background_light" (this results in white color) and the text color is "primary_text_light" (this results in black color).

I would have thought that primary_text_light would result in a "light" color like white, not black ;-)

When i change "primary_text_light" into "primary_text_dark" the text color becomes color white.

Is this a bug in the naming of the default colors?

Android :: Android - Color State List Resources - Specify A Background Color

Oct 17, 2010

To give the user of my app an indication which field currently has the focus I am trying to change the background color of some of my fields depending on the current state, however, I am having troubles understanding Androids Color State List Resources:

There is this example at the bottom of http://developer.android.com/guide/topics/resources/color-list-resource.html. If I try exactly the same, i.e. if I want to adapt the textColor , things do work. However, if I try an only slightly different thing, namely to adapt the background color, things do not work and I don't understand why? Why is this so inconsistent?

To make it simpler to understand what I am trying to do, I append my misc. .xml files:

The AndroidManifest.xml file:

CODE:.........

If I run this as shown here, it works, i.e. I get a button whose text color changes depending on whether the button is focuses, pressed, etc.

If I uncomment the lower button, where I just flipped the attribute values for textColor and background I get an exception, stating

... <item> tag requires a 'drawable' attribute or child tag defining a drawable

What the heck am I missing here? Why is that color state list acceptable as a text color but not as a background color? How does one specify a view's background color depending on the view's state?

Android : How Do I Set Color Back To "Color.BLACK" After User Releases Touchscreen

Mar 27, 2010

I'm programming my first Android application and I've stumbled over a little problem.

I've created my own adapter ("extends BaseAdapter") for my ListView and in my "public View getView(...)" I have the following code:

My problem: How do I set the color back to "Color.BLACK" after the user releases the touchscreen?

I'm looking for something that is similar to Javascripts "onMouseUp" or "onKeyUp" methods. An OnClickReleaseListener() perhaps?

Android :: SMS Not Give Delivery Time?

On previous non-smart phones I've been able to see not only that an SMS has been delivered, but also the time when it got delivered (ie when the recipient turned on their phone or whatever). Handcent will tell me whether or not it's been delivered, but not give a delivery time. Is this right? Is there any other app that can do this?

Android :: Android Color Picker - Updating Color Array

Oct 9, 2009

I'm trying to create a color picker for Android that looks like a minimalistic version of Gimp's. So, it has a hue slider and a rectangle with saturation/value variants of a color chosen in hue slider.

Question: what is the best way to create the rectangle?

Right now, I'm creating an 200x200 array of pixels, but it takes ~5sec to create and display rectangle with that array. And I need colors in rectangle to change whenever I change the value in hue slider...

Rectangle is bitmap, Can I use color matrices on that and how?
