  • I think you are using Android Color code- Color.Red etc? So please use color code for that like-#452558 and in your circle use other color code which one is lighter than etc.. OR use setAlpha(200); – Manish Srivastava Jul 09 '13 at 07:54

If the color is represented in hexadecimal, like #424242, then adding two more digits in front of this "number" will represent the transparency, ex: #66424242. (66 in this example)
You can play a bit until arrive at desired effect.

    so this `AA` ranges from `0 to 255` also `66` is how many % of 100? – User7723337 Jul 09 '13 at 07:57
  • Well, you could convert the hexa digits to decimal, and then do a simple math to know what percentage of transparency represent that alfa value. In this case, 66 would represent about 40%. – Andy Res Jul 09 '13 at 08:05

android:color="#66FF0000" is partially transparent red and if you decreasing the value of 6 as 5,4,3 up to 1 as "#56FF0000" ,"#46FF0000","#36FF0000","#26FF0000", the transparent color will becoming thin and the same way if u increase the first number as "#76FF0000","#86FF0000", like that the transparent color becoming thick.so we can arrange the transparency of color ourself. and it is applicable to all type of colors!!

Would something like this work?

android:color="#66FF0000"    // Partially transparent red

I have tried adding two digits to the front of the 'number' e.g. #66424242, this definitely works since I use it on my blog
