Transparent LinearLayout on Android

Question

I have the folowing layout:

enter image description here

I want to make transparent the transparent_layout but i can't do it.

Already tried settings the background programmatically with the color: Color.TRANSPARENT but it seems it doesnt work.

Im using Android 2.3.3 SDK with SherlockActionBar.

Is there any way to set that layout to transparent?

and also the code you are using the set the background color since you mentioned you're doing this programmatically. You have to use `setBackgroundColor` and not `setBackground` (just sayin' incase that's the issue). — Ali, May 08 '13 at 12:37

Depending upon the degree of opacity you like, set the background color like

        android:background="#00ffffff"

The first two digits are for opacity level, (aka alpha) that varies from 00 to ff (fully-transparent to fully-opaque), the remaining digits are for the desired background color. If you keep first 2 digits zero (00), then whatever color you choose for the remaining digits, doesn't matter.

00 is the transparency you want. Thanks – Naveed Ahmad Feb 15 '17 at 12:39

In XML change the main layout's (LinearLayout) background as android:background="@android:color/transparent" and also make sure that you are not giving the background to any of its child views.
