Set of light and non-invasive extensions for Android RecyclerView widget. Does not use custom RecyclerView or LayoutManager. With this extensions you can create RecyclerView with following features:
- Implemented using RecyclerView.OnItemTouchListener
- Support for custom "Drag frame" drawable
- ~350 LOC
dragDropTouchListener = new DragDropTouchListener(recyclerView, this) {
@Override
protected void onItemSwitch(RecyclerView recyclerView, int from, int to) {
adapter.swapPositions(from, to);
adapter.notifyItemChanged(to);
adapter.notifyItemChanged(from);
@Override
protected void onItemDrop(RecyclerView recyclerView, int position) {
}
};
}
recyclerView.addOnItemTouchListener(dragDropTouchListener);This is port of Roman Nurik's SwipeToDismiss for ListView
- Implemented using RecyclerView.OnItemTouchListener
- Configurable swipe directions: only left, only right, both, none
- ~320 LOC
swipeToDismissTouchListener = new SwipeToDismissTouchListener(recyclerView, new SwipeToDismissTouchListener.DismissCallbacks() {
@Override
public SwipeToDismissTouchListener.SwipeDirection canDismiss(int position) {
return SwipeToDismissTouchListener.SwipeDirection.RIGHT;
}
@Override
public void onDismiss(RecyclerView view, List<SwipeToDismissTouchListener.PendingDismissData> dismissData) {
for (SwipeToDismissTouchListener.PendingDismissData data : dismissData) {
adapter.removeItem(data.position);
adapter.notifyItemRemoved(data.position);
}
}
});
recyclerView.addOnItemTouchListener(swipeToDismissTouchListener);- Small RecyclerViewAdapter extension that can keep a state of selected/activated items
Use as normal RecyclerView.Adapter
As RecyclerView does not have standard way to add click listeners to the items, this RecyclerView.OnItemTouchListener intercepts touch events and translates them to simple onItemClick() and onItemLongClick() callbacks.
recyclerView.addOnItemTouchListener(new ItemTouchListenerAdapter(recyclerView, this));Sample app code is included, please see DemoActivity.
