Android Layout Manager (table layout)

Source: Internet
Author: User

Table layout is represented by Tablelayout, Tablelayout inherited LinearLayout, so his essence is still linearlayout.

Table layouts are managed in rows and columns, where you don't need to declare how many rows and columns to use, but instead add tablerow and other components to control the number of rows and columns in the table.

Each time you add a TableRow to Tablelayout, the TableRow is a table row, and TableRow is also a container where you can add additional components continuously, adding a column to each of the table's columns.

In the table layout manager, you can set the following three ways to behave for cells

    1. Shrinkable: If a column is set to Shrinkable, the width of all cells in the column can be shrunk to ensure that the table fits the width of the parent container
    2. Stretchable: If a column is set to Stretchable, then the width of all the cells in the column can be stretched to ensure that the component fills the table free control
    3. Collapsed: If a column is set to this property, all cells of that column will be hidden

Because Tablelayout inherits the LinearLayout class, the following three properties are supported in addition to all properties that support LinearLayout
