What is the difference between gravity and layout_gravity in Android?

The Difference Between android:gravity and android:layout_gravity in Android

If you've ever worked with Android layout properties, you've probably come across android:gravity and android:layout_gravity. While they may sound similar, these two properties actually serve different purposes. Let's dive in and explore the differences between them!

Understanding android:gravity

The android:gravity property is used to define the gravity of the content within a View. In simpler terms, it determines the alignment of the text or other elements inside the View. The available values for android:gravity include:

• center: This centers the content both horizontally and vertically within the View.

• center_vertical: This centers the content vertically within the View.

• center_horizontal: This centers the content horizontally within the View.

• and many more...

Let's say we have a TextView element like this:

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:gravity="center"
    android:text="Hello, World!" />

With android:gravity="center", the text "Hello, World!" will be centered both horizontally and vertically within the TextView.

Exploring android:layout_gravity

On the other hand, android:layout_gravity is used to control the gravity of the View itself within its parent container. It determines the position of the View relative to its parent container. The available values for android:layout_gravity include:

• center: This centers the View both horizontally and vertically within its parent container.

• center_vertical: This centers the View vertically within its parent container.

• center_horizontal: This centers the View horizontally within its parent container.

• and many more...

Let's consider an example using a Button element:

<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:text="Click Me!" />

Here, with android:layout_gravity="center", the Button will be positioned at the center of its parent container, both horizontally and vertically.

Getting Rid of the Confusion

To summarize, remember that android:gravity controls the alignment of the content within a View, while android:layout_gravity controls the position of the View itself within its parent container.

If you find yourself getting confused between the two, try to remember that layout_gravity is all about positioning the View within its parent, while gravity adjusts the alignment of the content inside the View.

Also, keep in mind that these properties can be used with various types of Views, such as TextView, Button, ImageView, etc. So the same principles apply across different elements.

Your Turn to Play with Gravity!

Now that you have a better understanding of the differences between android:gravity and android:layout_gravity, it's time to apply this knowledge in your Android projects. Experiment with different values and see how the alignment and positioning change!
