GridLayout Grid layout of Android layout _android

The Grid layout label is GridLayout. This layout is a new layout for android4.0. This layout is only available after 4.0 versions.

But some new stuff.

① like LinearLayout (linear layout), he can set the alignment of a component in a container

Components in a ② container can span multiple rows or across multiple columns (compared to tablelayout, which takes up a single line of components)

Because it's Android 4.0 new, API level 14, in this version of the previous SDK

You need to import the project, and then we'll explain it in detail.

Common Properties:

Arrange alignment:

① sets the arrangement of the components: android:orientation= "" Vertical (vertical, default) or horizontal (horizontal)

② set the alignment of the component: android:layout_gravity= "" Center,left,right,buttom, these, if you want to use two words at the same time: Eg:buttom|left
