layout_weight is used in LinearLayouts to assign “importance” to Views within the layout. All Views have a default layout_weight of zero, meaning they take up only as much room on the screen as they need to be displayed. Assigning a value higher than zero will split up the rest of the available space in the parent View, according to the value of each View’s layout_weight and its ratio to the overall layout_weight specified in the current layout for this and other View elements.
