The red color shows where is it.Just edit it to what ever color you want.for example android:background="#00000000" to make it pure white.

The color code is made like this:

ggRRGGBB

where,

gg-Gamma (responsible for the transparency)

RR-contribution of red

GG-contribution of green

BB-contribution of blue.

Always the colors are given as hex.Whenever you give the color make sure you prefix the color with #.

To calculate the hex value for a given percent,Use this formula: (255/100)*x.Where x is the percentage of transparency you want.

You can do this in windows calculator by these steps:

1.Open win calc and press alt+3

2.make sure decimal radio button is clicked centre left of win calc

3.apply the formula I gave you above

4.after you get your value click on hex radio button on the centre left box of win calc and you will have the hex value.

To get the value of RRGGBB in hex this will be useful :)

Tip:00 means no contribution of that color.ff means full contribution of that color.

Hence for 000000 there is no contribution of Red,Green and Blue.So the color is white.For ffffff Red,Green and Blue gives full contribution so black :).Note:The above example is without gamma.That is,it is jut RRGGBB with missing gg :)
