Grid layout android example

GridLayout works with a flat-view hierarchy, where child views set their locations in the grid by specifying the rows and columns they should be in. This way, the GridLayout is able to position views in the grid without requiring that any intermediate views provide a table structure, such as seen in the table rows used in the TableLayout.

By maintaining a flat hierarchy, GridLayout is able to more swiftly layout its child views. The layout will adjust the row and column sizes so that the cells can fit their content, as illustrated by the following diagram:.

When these are not specified, the GridLayout assigns each child view in order, based upon the orientation. Now, the GridLayout will position the cells from top to bottom in each column, instead of left to right, as shown below:. For example, the following XML will result in the layout shown in the first screenshot shown aboveregardless of the orientation. We have a couple of options that will provide spacing between the child views of the GridLayout.

Additionally, in Android 4, a new general-purpose spacing view called Space is now available. To use it, simply add it as a child view. For example, the XML below adds an additional row to the GridLayout by setting its rowcount to 3, and adds a Space view that provides spacing between the TextViews.

The GridLayout also supports cells that span multiple columns and rows. For example, say we add another row containing a button to the GridLayout as shown below:. This will result in the first column of the GridLayout being stretched to accommodate the size of the button, as we see here:.

To keep the first column from stretching, we can set the button to span two columns by setting its columnspan like this:. Doing this results in a layout for the TextViews that is similar to the layout we had earlier, with the button added to the bottom of the GridLayout as shown below:. Skip to main content.
