[Android Layout Learning Series]

1.Android Layout Learning--layout (layout) detailed one

2.Android Layout Learning--layout (layout) detailed two (common layout and layout parameters)

The Layout_weight attribute of the--linearlayout of 3.Android layout learning

The function and baseline of--linearlayout attribute baselinealigned in 4.Android layout learning

1. What are the differences?

Android:gravity:

defines the contents of an object in an X, Y axis, within its own bounds, and how it should be placed.

android:layout_gravity :

The standard gravity constant, which is the parent component that the child component provides to it. Defines how the child view should be placed in the X, y direction in the closed layout .

If you need to set multiple gravity values, use the ' | ' Symbol Delimited. Such as

Android:layout_gravity= "Right|bottom"

Android:gravity= "Right|bottom"

2. Differences

Look at the name to see some differences: android:layout_gravity and layout.

Android:gravity sets the gravity of the view's contents.

Android:layout_gravity Sets the view or layout of the gravity in its parent layout.
