Adds a callback to be notified of various events and requests from this ReportViewController so that an enclosing Activity can appropriately handle requests or react to events. An enclosing Activity might implement a listener like this:

onBackPressed

fun onBackPressed(): Boolean

Handle a back action instigated elsewhere in the app. This method should be called, for example, from the owning Activity's onBackPressed method.

onContextItemSelected

fun onContextItemSelected(item: MenuItem): Boolean

Needs to be called by the implementing activity to support the selection of ContextMenu items

onCreateContextMenu

fun onCreateContextMenu(menu: ContextMenu?, v: View?, menuInfo: ContextMenu.ContextMenuInfo?)

Needs to be called by the implementing activity to support the creation of ContextMenus

onOptionsItemSelected

fun onOptionsItemSelected(item: MenuItem): Boolean

Called whenever an item in your options menu is selected. This method should be called, for example, from the owning Activity's onOptionsItemSelected method.

onPrepareOptionsMenu

fun onPrepareOptionsMenu(menu: Menu)

Prepares the standard options menu to be displayed. This method should be called, for example, from the owning Activity's onPrepareOptionsMenu method.

removeReportEventListener

fun removeReportEventListener(onReportEvent: (event: ReportEvent) -> Unit)

Removes a callback that was previously added with addReportEventListener.
