Android: Color To Int conversion
This might be a stupid question but I'm surprised that Paint
class has no setColor(Color c)
method. I want to do the following:
public void setColor(Color color) {
/* ... */
Paint p = new Paint();
p.setColor(color); // set color takes only int as a paramter :(
/* ... */
}
So any easy way to convert Color
to int
?
Any color
parse into int
simplest two way here:
1) Get System Color
int redColorValue = Color.RED;
2) Any Color Hex Code as a String Argument
int greenColorValue = Color.parseColor("#00ff00")
MUST REMEMBER in above code Color
class must be android.graphics...
!
All the methods and variables in Color are static. You can not instantiate a Color object.
Official Color Docs
The Color class defines methods for creating and converting color ints.
Colors are represented as packed ints, made up of 4 bytes: alpha, red, green, blue.
The values are unpremultiplied, meaning any transparency is stored solely in the alpha component, and not in the color components.
The components are stored as follows (alpha << 24) | (red << 16) | (green << 8) | blue.
Each component ranges between 0..255 with 0 meaning no contribution for that component, and 255 meaning 100% contribution.
Thus opaque-black would be 0xFF000000 (100% opaque but no contributions from red, green, or blue), and opaque-white would be 0xFFFFFFFF
R.color.black
or some color are obviously integers. It needs a RGB value. You can give your own like #FF123454
which represents various primary colors
