Android - How to set color value to TRANSPARENT

just used android color string

mPaint.setColor(getResources().getColor(android.R.color.transparent));

Suppose your preferred color is red #FF0000

Adding 00 in the beginning will make it 100% transparent and adding FF will make it 100% solid.

So, 100% transparent color is: #00ff0000 and 100% solid color is: #ffff0000

And any value in between 00 to ff can be used to adjust the transparency.
