Basically you have the option to set the transparency (opacity) and the color using android:background.

The hex value that you set it to is composed of 3 to 4 parts:

Alpha (opacity), i'll refer to that as aa
Red, i'll refer to it as rr
Green, i'll refer to it as gg
Blue, i'll refer to it as bb

Without an alpha (transparency) value:

android:background="#rrggbb"

With an alpha (transparency) value:

android:background="#aarrggbb"

The alpha value for full transparency is 00 and the alpha value for no transparency is FF

You can experiment with values in between those.

Try out with android:textColor="#00000000". This code is for the transparent color only.

When you set the text color try using #24ffffff or some other combination, the first two digits are for the alpha, and you can adjust the opacity of the text.

To get transparency in any of your color add 88 or 44 before your color code as per your requirement of transparency level. for example, to get black transparent color use code "#88000000"

so just get your color code and add the prefix to it and set the color as below example.

android:textColor="#88000000"
