First, I set the green color to be the background of the View mIcon,
View mIcon = findViewById(R.id.xxx);
GradientDrawable gdraw = (GradientDrawable) mContext.getResources().getDrawable(R.drawable.roundbtn_white_normal);
gdraw.setColor(Color.GREEN);
mIcon.setBackgroundDrawable(gdraw);
Then, I don't know how to get the color from this View's background... there's no getColor() function...
the following class works fine for me so far.
import android.content.res.Resources;
...
// it's the same with the GradientDrawable, just make some proper modification to make it compilable
public class ColorGradientDrawable extends Drawable {
...
private int mColor; // this is the color which you try to get
...
// original setColor function with little modification
public void setColor(int argb) {
mColor = argb;
mGradientState.setSolidColor(argb);
mFillPaint.setColor(argb);
invalidateSelf();
}
// that's how I get the color from this drawable class
public int getColor() {
return mColor;
}
...
// it's the same with GradientState, just make some proper modification to make it compilable
final public static class GradientState extends ConstantState {
...
}
}
