I was wondering how to change my code to make it work properly:
Red.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
@Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
seekr = Red.getProgress();
seekg = Green.getProgress();
seekb = Blue.getProgress();
button1.setBackgroundColor(
0xff000000
+seekr*0x10000
+seekg*0x100
+seekb
);
button2.setBackgroundColor(
0xff000000
+seekr*0x10000
+seekg*0x100
+seekb
);
}
@Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
@Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
});
this is the method that i'm using to change the value of the Red parameter, and i'm controlling also the other 2 colors in the same way. The problem is that when all the seekbars are set on 0 the background color of the buttons is black, and if they are all set at the maximum value the background color is grey; so i can't have the white color. Why is this code not working properly?
Not sure if you are wanting white or not but could try using:
button1.SetBackgroundColor(Color.argb(255, seekr, seekg, seekb));
button2.SetBackgroundColor(Color.argb(255, seekr, seekg, seekb));
