In my application, I apply the transparent background to my ListView's CustomListItem at runtime. For that I use, convertView.setBackgroundColor(android.R.color.transparent);. It works and shows transparency. But that is not fully transparent as there is some kind of shade to the background. I also tried putting my own transparent color with the values #80000000 and #00000000 but the result is worse. What can I do to get the fully transparent color?

Set this attribute to your listview in xml file

android:background="@android:color/transparent"

and also apply the transparent background to your ListView's CustomListItem at runtime. For that you have use, 

convertView.setBackgroundColor(Color.TRANSPARENT);

Thanks

    No man. Read my question. `convertView.setBackgroundColor(android.R.color.transparent);` was not working. Read @antonyt answer. It worked. – Rajkiran Apr 03 '12 at 07:27

android.R.color.transparent is a resource id (referring to a transparent color definition) - View.setBackgroundColor(int) expects an actual int color.

Use View.setBackgroundResource(int) instead, which will load the actual color from resources.

convertView.setBackgroundColor(Color.argb(0, 0, 0, 0));

OR

convertView.setBackgroundColor(Color.parseColor("#00000000"));

Use this from now in your xml's files when you want transparency in your views:

android:background="@null"

You are going to get a better performance.

Try:

convertView.setBackgroundColor(Color.argb(0, 0, 0, 0));
