Android learning-layout tablelayout table layout

Table layout contains a series of tablerow objects for defining rows (you can also use other sub-objects, which will be explained later ). The table layout does not display table lines for its rows, columns, and cells. Each row can contain more than 0 (including 0) cells, and each cell can set a view object. Like a row that contains many cells, a table contains many columns. Cells in a table can be empty. cells can span columns as HTML does.

The column width is determined by the widest cell in all rows of the column. however, you can use the setcolumnshrinkable () method or the setcolumnstretchable () method to mark whether certain columns can be shrunk or stretched. if it is marked as condensed, the column width can be reduced to make the table fit the container size. If it is marked as extensible, the column width can be stretched to occupy extra space. The total width of a table is determined by its parent container. It is important to remember that columns can be stretched and shrunk simultaneously. It is useful when the column width can be adjusted to occupy available space, but it cannot exceed the limit. Finally, you can hide the column by calling setcolumncollapsed.

The layout_width attribute cannot be specified for sub-objects in table layout. The width is always match_parent. However, the layout_height attribute can be defined for sub-objects. The default value is wrap_content. If the sub-object is tablerow, its height will always be wrap_content.

The following example shows how to design the interface...
