Android SwipeableRecyclerView

Based on romannurik`s Android-SwipeToDismiss.

Sample project implementation of a list of CardViews in a RecyclerView with a TouchListener that allows dismissing of elements by swiping the elements to the left or right.

####How to use

• Add these Gradle dependencies to your app's module:

  dependencies {
      ...
      
      // already includes 'com.android.support:recyclerview-v7:23.1.1'
      compile 'com.github.brnunes:swipeablerecyclerview:1.0.2'
  
      // only necessary if you are using CardView
      compile 'com.android.support:cardview-v7:23.1.1'
  }
  

The RecyclerView and CardView widgets are part of the v7 Support Libraries.

• Instantiate a SwipeableRecyclerViewTouchListener passing as parameters the RecyclerView and a SwipeableRecyclerViewTouchListener.SwipeListener that will receive the callbacks.

• Add the instantiated SwipeableRecyclerViewTouchListener as a RecyclerView.OnItemTouchListener.

  SwipeableRecyclerViewTouchListener swipeTouchListener =
          new SwipeableRecyclerViewTouchListener(mRecyclerView,
                  new SwipeableRecyclerViewTouchListener.SwipeListener() {
                      @Override
                      public boolean canSwipeLeft(int position) {
                          return true;
                      }
  
                      @Override
                      public boolean canSwipeRight(int position) {
                          return true;
                      }
  
                      @Override
                      public void onDismissedBySwipeLeft(RecyclerView recyclerView, int[] reverseSortedPositions) {
                          for (int position : reverseSortedPositions) {
                              mItems.remove(position);
                              mAdapter.notifyItemRemoved(position);
                          }
                          mAdapter.notifyDataSetChanged();
                      }
  
                      @Override
                      public void onDismissedBySwipeRight(RecyclerView recyclerView, int[] reverseSortedPositions) {
                          for (int position : reverseSortedPositions) {
                              mItems.remove(position);
                              mAdapter.notifyItemRemoved(position);
                          }
                          mAdapter.notifyDataSetChanged();
                      }
                  });
  
  mRecyclerView.addOnItemTouchListener(swipeTouchListener);
