Change Listview cell opacity

Question

I want to change the opacity of some cell of my ListView.

I don't know the color to apply, only the alpha, so I can't use :

v.setBackgroundColor(0x44FFFFFF);

I have to use somethings like :

v.setAlpha(50);

Answer 1

Yes you can use setAlpha.

The function View.setAlpha(float) expects a value between 0 and 1.

See here: http://developer.android.com/reference/android/view/View.html#setAlpha%28float%29

Answer 2

You can try this too:

myView.setBackgroundColor(getResources()
            .getColor(R.color.translucent));//here translucent = "#80FFFF" ARGB format

Please refer here for more details on transparency values.
