How to make a Drawable object with my selected color in code

Question

I am trying to set icon of selected color to a preference:

Preference prf = (Preference) findPreference(\"SelectColorPref\");

prf.setIcon

Answer 1

the easiest way using ShapeDrawable

 ShapeDrawable sdrawable = new ShapeDrawable(new RectShape());
 sdrawable.paint.Color = color.RED;
 sdrawable.setIntrinsicWidth(10);
 sdrawable.setIntrinsicHeight(40);

Answer 2

You should be able to create a solid-colour Drawable using code similar to this:

Bitmap bm = BitmapFactory.createBitmap(50, 50, Bitmap.Config.ARGB_8888);
Canvas cnv = new Canvas(bm);
int red = 0xff0000;
cnv.drawColor(red);
Drawable drawable = new BitmapDrawable(bm);

This will create a Drawable containing a 50x50 pixels red square.

(Please note that I haven't tested this code, but I use something similar in my code.)
