Use with RecyclerView, ListView, GridView...

In your Adapter class:

public class Adapter extends RecyclerView.Adapter {
  // This object helps you save/restore the open/close state of each view
  private final ViewBinderHelper viewBinderHelper = new ViewBinderHelper();
  
  public Adapter() {
    // uncomment the line below if you want to open only one row at a time
    // viewBinderHelper.setOpenOnlyOne(true);
  }
  
  @Override
  public void onBindViewHolder(ViewHolder holder, int position) {
    // get your data object first.
    YourDataObject dataObject = mDataSet.get(position); 
    
    // Save/restore the open/close state.
    // You need to provide a String id which uniquely defines the data object.
    viewBinderHelper.bind(holder.swipeRevealLayout, dataObject.getId()); 

    // do your regular binding stuff here
  }
}

Optional, to restore/save the open/close state when the device's orientation is changed:

Adapter class:

public class YourAdapter extends RecyclerView.Adapter {
  ...

  public void saveStates(Bundle outState) {
      viewBinderHelper.saveStates(outState);
  }

  public void restoreStates(Bundle inState) {
      viewBinderHelper.restoreStates(inState);
  }  
}

Activity class:

public class YourActivity extends Activity {
  ...
  
  @Override
  protected void onSaveInstanceState(Bundle outState) {
      super.onSaveInstanceState(outState);
      if (adapter != null) {
          adapter.saveStates(outState);
      }
  }

  @Override
  protected void onRestoreInstanceState(Bundle savedInstanceState) {
      super.onRestoreInstanceState(savedInstanceState);
      if (adapter != null) {
          adapter.restoreStates(savedInstanceState);
      }
  }
}

Useful Methods/Attributes

app:minDistRequestDisallowParent: The minimum distance (in px or dp) to the closest drag edge that the SwipeRevealLayout will disallow the parent to intercept touch event. It basically means the minimum distance to swipe until a RecyclerView (or something similar) cannot be scrolled.

setSwipeListener(SwipeListener swipeListener): set the listener for the layout. You can use the full interface SwipeListener or a simplified listener class SimpleSwipeListener

open(boolean animation), close(boolean animation): open/close the layout. If animation is set to false, the listener will not be called.

isOpened(), isClosed(): check if the layout is fully opened or closed.

setMinFlingVelocity(int velocity): set the minimum fling velocity (dp/sec) to cause the layout to open/close.

setDragEdge(int edge): Change the edge where the layout can be dragged from.

setLockDrag(boolean lock): If set to true, the user cannot drag/swipe the layout.

viewBinderHelper.lockSwipe(String... id), viewBinderHelper.unlockSwipe(String... id): Lock/unlock layouts which are binded to the binderHelper.

viewBinderHelper.setOpenOnlyOne(boolean openOnlyOne): If openOnlyOne is set to true, you can only open one row at a time.

viewBinderHelper.openLayout(String id): Open a layout. id is the id of the data object which is bind to the layout.

viewBinderHelper.closeLayout(String id): Close a layout. id is the id of the data object which is bind to the layout.
