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?

Solution 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.

Solution 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);

Thanks

Solution 3

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

OR

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

Solution 4

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.

Solution 5

Try:

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

No man. Read my question. convertView.setBackgroundColor(android.R.color.transparent); was not working. Read @antonyt answer. It worked.

worked, but why it's not working the obvious way is still a mystery.
