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?

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
View 1 Replies View RelatedI 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);

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 want to draw a shape(many circles particularly) into a Specific Bitmap. I have never used canvas / 2D graphs etc. As i see it i create a Drawable put the bitmap in it then "canvas-it" to the shapes i want etc.

Is there any process to change the default text color white to "Black" and default selection color of android "orange" to "Blue" for whole project. i am using Eclipse for Android development.
View 3 Replies View Related1. I want to use my own color for selecting ui views.
By default, android shows the selected view with background as orange. I want to show the view background color as red.
2. In the same way, I want the same behaviour should be applied to whole application.
I have seen this example:
@*android:color/secondary_text_light
What's that * asterisk doing there? What is the difference when using or not?

View 2 Replies View RelatedIn android, when I press on a TextView, the text changes color (from white to grey). how can I disable that functionality?
View 1 Replies View RelatedI 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?
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?
I'm programming my first Android application and I've stumbled over a little problem.

I use Handcent for text messaging. 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?

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?
