what does android:id="@+id/label mean?

Hi all

This is my first question on android. I am learning android very late I know & I have a question.

Can anyone explain me this statement below.

android:id="@+id/label

what does it mean by the plus sign I am going through the tutorial on android.

There is no explanation of this & I was hoping if someone can explain it to me.

Thanks

+id/label means that your resource will have an id value = label and that label belongs to your application's name space.
There are many resources bundled with android.jar file and when referring to these resources you would say android:id = "@android:id/list" which means your resource will have an id value = list and that this value belongs to android name space.

Refer this.

Thanks

Now I understand. + sign only means when creating a variable or ID. Else when you use it you mention without the + sign.
