Swipe to Dismiss for RecyclerView [closed]

Question

As of v22.2.0, the Android support team has included an ItemTouchHelper class that makes swipe-to-dismiss and drag-and-drop pretty simple. This may not be as full-featured as some of the libraries out there, but it comes directly from the Android team.

• Update your build.gradle to import v22.2.+ of the RecyclerView library

  compile 'com.android.support:recyclerview-v7:22.2.+'
  

• Instantiate an ItemTouchHelper with an appropriate SimpleCallback

  ItemTouchHelper.SimpleCallback simpleItemTouchCallback = new ItemTouchHelper.SimpleCallback(0, ItemTouchHelper.LEFT | ItemTouchHelper.RIGHT) {
      [...]
      @Override
      public void onSwiped(RecyclerView.ViewHolder viewHolder, int swipeDir) {
          //Remove swiped item from list and notify the RecyclerView
      }
  };
  
  ItemTouchHelper itemTouchHelper = new ItemTouchHelper(simpleItemTouchCallback);
  

  ** Note that the SimpleCallback takes in the directions that you want to enable drag-and-drop and the directions that you want to enable swiping.

• Attach to your RecyclerView

  itemTouchHelper.attachToRecyclerView(recyclerView);
  

 ItemTouchHelper.SimpleCallback simpleCallback = new ItemTouchHelper.SimpleCallback(0, ItemTouchHelper.LEFT) {
        @Override
        public boolean onMove(RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder, RecyclerView.ViewHolder target) {
            return false;
        }

        @Override
        public void onSwiped(final RecyclerView.ViewHolder viewHolder, int direction) {
            final int position = viewHolder.getAdapterPosition(); //get position which is swipe

            if (direction == ItemTouchHelper.LEFT) {    //if swipe left

                AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this); //alert for confirm to delete
                builder.setMessage("Are you sure to delete?");    //set message

                builder.setPositiveButton("REMOVE", new DialogInterface.OnClickListener() { //when click on DELETE
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        adapter.notifyItemRemoved(position);    //item removed from recylcerview
                        sqldatabase.execSQL("delete from " + TABLE_NAME + " where _id='" + (position + 1) + "'"); //query for delete
                        list.remove(position);  //then remove item

                        return;
                    }
                }).setNegativeButton("CANCEL", new DialogInterface.OnClickListener() {  //not removing items if cancel is done
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        adapter.notifyItemRemoved(position + 1);    //notifies the RecyclerView Adapter that data in adapter has been removed at a particular position.
                        adapter.notifyItemRangeChanged(position, adapter.getItemCount());   //notifies the RecyclerView Adapter that positions of element in adapter has been changed from position(removed element index to end of list), please update it.
                        return;
                    }
                }).show();  //show alert dialog
            }
        }
    };
    ItemTouchHelper itemTouchHelper = new ItemTouchHelper(simpleCallback);
    itemTouchHelper.attachToRecyclerView(recyclerView); //set swipe to recylcerview

Here in Code if user swipe left then AlertDialog is displayed and if user select REMOVE then item is deleted from database and recyclerview is refreshed and if user select CANCEL then recyclerview is as it is.

maybe you could try this library:

Update: I've just found another good library that you can use with RecyclerView:

https://github.com/hudomju/android-swipe-to-dismiss-undo

This library may be helpful.You can implement undo in OnDissmiss use supertoast
