Example 2 with UndoHelper

use of eu.davidea.flexibleadapter.helpers.UndoHelper in project FlexibleAdapter by davideas.

the class MainActivity method onItemSwipe.

@Override
public void onItemSwipe(final int position, int direction) {
    Log.i(TAG, "onItemSwipe position=" + position + " direction=" + (direction == ItemTouchHelper.LEFT ? "LEFT" : "RIGHT"));
    // Option 1 FULL_SWIPE: Direct action no Undo Action
    // Do something based on direction when item has been swiped:
    //   A) update item, set "read" if an email etc.
    //   B) remove the item from the adapter;
    // Option 2 FULL_SWIPE: Delayed action with Undo Action
    // Show action button and start a new Handler:
    //   A) on time out do something based on direction (open dialog with options);
    // Create list for single position (only in onItemSwipe)
    List<Integer> positions = new ArrayList<>(1);
    positions.add(position);
