  • Supports any view for "Swipe Options"
  • Doesn't require any new adapters or new views. Works with any existing RecyclerViews.
  • Requires adding OnItemTouchListener to the RecyclerView

  • Supports disabling clicking and swiping for particular items/rows.
  • Supports independentViews in your items/rows (Read below for more information)
  • Supports fadeViews in your items/rows (Read below for more information)

Demo

Build the sample application to try RecyclerViewEnhanced alt text

Configuring

  • Create an instance of RecyclerTouchListener

    onTouchListener = new RecyclerTouchListener(this, mRecyclerView);

  • Set IndependentViews and FadeViews (If required)

    IndependentViews are views which can be clicked separately from the entire row. Their clicks have different functionality from row clicks. FadeViews are views which fade in and out as the rows are swiped closed and opened respectively.

    onTouchListener.setIndependentViews(R.id.rowButton)
               .setViewsToFade(R.id.rowButton)

  • Implement OnRowClickListener using setClickable()

    setClickable() will enable clicks for the recycler view items and the IndependentViews

    .setClickable(new RecyclerTouchListener.OnRowClickListener() {
          @Override
          public void onRowClicked(int position) {
              // Do something
          }

          @Override
          public void onIndependentViewClicked(int independentViewID, int position) {
              // Do something
          }
      })

  • Enable Swipe Functionality

    Set the views for which you require a click listener and enable swiping by using setSwipeable()

    .setSwipeOptionViews(R.id.add, R.id.edit, R.id.change)
.setSwipeable(R.id.rowFG, R.id.rowBG, new RecyclerTouchListener.OnSwipeOptionsClickListener() {
          @Override
          public void onSwipeOptionClicked(int viewID, int position) {
              if (viewID == R.id.add) {
                  // Do something
              } else if (viewID == R.id.edit) {
                  // Do something
              } else if (viewID == R.id.change) {
                  // Do something
              }
         }
     });

  • Adding the listener to the RecyclerView

    In onResume() add the listener:

    mRecyclerView.addOnItemTouchListener(onTouchListener);

    In onPause() remove the listener:

    mRecyclerView.removeOnItemTouchListener(onTouchListener);

Additional Functionality

  • Use onRowLongClickListener to receive long click events

    .setLongClickable(true, new RecyclerTouchListener.OnRowLongClickListener() {
                  @Override
                  public void onRowLongClicked(int position) {
                      ToastUtil.makeToast(getApplicationContext(), "Row " + (position + 1) + " long clicked!");
                  }
              })

  • Use setUnSwipeableRows() to disable certain rows from swiping. Using this also displays an "difficult-to-slide" animation when trying to slide an unswipeable row.

  • Use setUnClickableRows() to disable click actions for certain rows. (Note: This also prevents the independentViews from being clicked).

  • openSwipeOptions() opens the swipe options for a specific row.

  • closeVisibleBG() closes any open options.

  • Implement OnSwipeListener to get onSwipeOptionsClosed() and onSwipeOptionsOpened() events.

Closing swipe options when clicked anywhere outside of the recyclerView:

  • Make your Activity implement RecyclerTouchListener.RecyclerTouchListenerHelper and store the touchListener
private OnActivityTouchListener touchListener;

@Override
public void setOnActivityTouchListener(OnActivityTouchListener listener) {
    this.touchListener = listener;
}
  • Override dispatchTouchEvent() of your Activity and pass the MotionEvent variable to the touchListener
@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
    if (touchListener != null) touchListener.getTouchCoordinates(ev);
        return super.dispatchTouchEvent(ev);
}
