The gravity of the child is controlled via the android:layout_gravity property. The child of a GridLayout can be configured to span multiple cells using the android:layout_rowSpan and android:layout_columnSpan properties. The following Button view will be placed in the cell and row 1, column 2 of the parent GridLayout: ĭeclaring Cell Spanning, Gravity and Margins The above layout would be visually represented as illustrated in Figure 16-1:Ī view can be placed within a specific cell by specifying the intersecting row and column number of the destination cell. The following XML places four buttons within the above GridLayout, with each view placed in the top left hand corner of the encapsulating cell: If no row and column values are declared for a child it is positioned automatically by the GridLayout class based on the configuration of the layout and the position of the view in the XML file. Report this ad Adding Child Views to the GridLayoutĬhild views can be added to a GridLayout by declaring the elements within the structure in the XML file. The following example XML declares a 2 x 2 GridLayout configuration in horizontal orientation:
Similarly, the orientation of the GridLayout may optionally be defined via the android:orientation property. Typically, however, if the number of columns is declared the GridLayout will infer the number of rows based on the number of occupied cells making the use of the rowCount property unnecessary. The number of rows and columns within the grid can be declared using the android:rowCount and android:columnCount properties.
A GridLayout is declared within an XML file using the element tag.
