Android sideslip and breakpoint sequel

Note: to write in the position of the layout, replace the linear or relative layout, and write two sub layouts. The first is the sideslip layout, which is displayed off the screen by default. The second is the layout to be displayed;

The custom class inherits recyclershiplayout and overrides getswipelayoutresourceid (postion)

Common methods: setmode: set sideslip mode openitem: open closeitem: close
