"Android Layout" set Android:gravity and Android:layout_gravity properties in your program

The LinearLayout has two very similar properties:

Android:gravity and Android:layout_gravity.

The difference between them is:

The Android:gravity property is the qualification for the content in the view. For example, a button above the text. You can set the text relative to the view's left, right, and so on.

Android:layout_gravity is used to set the location of the view relative to the parent view. For example, a button in the LinearLayout, you want to put the button in the LinearLayout left, on the right and so on can be set by this property.

That is, android:gravity is used to set the alignment of content in view relative to the view component, while android:layout_gravity is used to set the alignment of the view component with respect to the container.

The principle is a bit similar to Android:paddingleft and Android:layout_marginleft. If both properties are set at the same time on the button.

Android:paddingleft= the content set on the 30px button is 30 pixels from the left edge of the button
Android:layout_marginleft= "30px" The entire button is set from the left side of the content 30 pixels

To get back to the point below, we can set the android:gravity= "center" to let the text in the EditText be centered in the EditText component, while we set the android:layout_gravity= of EditText " Right "to let the EditText component appear in the LinearLayout. Look at the effect:

As we can see, in EditText, where the text is already centered, and the EditText component itself is aligned to the right side of the linearlayout.

Attach the layout file:

[XHTML]View PlainCopy

2. <LinearLayout
4. xmlns:android="http://schemas.android.com/apk/res/android"
6. android:orientation="vertical"
8. android:layout_width="fill_parent"
10. android:layout_height="fill_parent">
12. <EditText
14. android:layout_width="wrap_content"
16. android:gravity="center"
18. android:layout_height="wrap_content"
20. android:text="one"
22. android:layout_gravity="right"/>
24. </linearlayout>
