android.R.color.transparent not fully transparent

Question

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?

Answer 1

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.

Answer 2

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);
