What is the difference between gravity and layout_gravity in Android?

itemprop="text">

I know we can set the following values
to the android:gravity and
android:layout_gravity
properties:

1. center


2. center_vertical



3. center_horizontal,
   etc.

But I am confused
regarding both of these.

What is the difference
between the usage of android:gravity and
android:layout_gravity?

Answer

Their names should help
you:

• android:gravity
  sets the gravity of the contents (i.e. its subviews) of the
  View it's used on.
  


• android:layout_gravity sets the
  gravity of the View or Layout relative
  to its parent.
