Android layout tablelayout Table layout _android

The Tablelayout class manages controls in rows and columns, with each behavior a TableRow object, or a view control. When you are TableRow an object, you can add child controls under TableRow, and each child control occupies a column by default. When you view, the view is exclusive to one row.

Three commonly used properties

Android:collapsecolumns: Sets the ordinal number of the column that needs to be hidden

Android:shrinkcolumns: Sets the column number of the column that is allowed to be shrunk

Android:stretchcolumns: Sets the column number of the column that is to run the extrusion

Learning Guide Map

(1) A brief introduction to Tablelayout

Java's swing programming and HTML are often used in tables, visible tables are used in application development, and Android also provides us with this layout.

(2) How to determine the number of rows

A: Directly to the tablelayout component, directly to the line

B: If you want to add more than one component on a single line, you need to use TableRow to add

How many components in the C:tablerow, how many columns will there be in this line

(3) Three common properties (all are counted from zero)

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;

Stretchable: If a column is set to Stretchable, the width of all the cells in the column can be stretched to ensure that the component fills the table free space completely;

Collapsed: If a column is set to collapsed, all cells of that column are hidden;

(4) Use instance (no component has an ID set for the demo effect)
