As I mentioned previously, I took the same approach and it seems to work as expected. I have added 3 layers to a RelativeLayout. Top layer is what you want to show. Second layer is a plain background with delete icon at the left. Third layer is another plain background with share icon at the right. I implemented a swipe detector class which extends View.OnTouchListener.

public class SwipeDetector implements View.OnTouchListener {

    private static final int MIN_DISTANCE = 300;
    private static final int MIN_LOCK_DISTANCE = 30; // disallow motion intercept
    private boolean motionInterceptDisallowed = false;
    private float downX, upX;
    private ObjectHolder holder;
    private int position;

    public SwipeDetector(ObjectHolder h, int pos) {
        holder = h;
        position = pos;
    }

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        switch (event.getAction()) {
        case MotionEvent.ACTION_DOWN: {
            downX = event.getX();
            return true; // allow other events like Click to be processed
        }

        case MotionEvent.ACTION_MOVE: {
            upX = event.getX();
            float deltaX = downX - upX;

            if (Math.abs(deltaX) > MIN_LOCK_DISTANCE && listView != null && !motionInterceptDisallowed) {
                listView.requestDisallowInterceptTouchEvent(true);
                motionInterceptDisallowed = true;
            }

            if (deltaX > 0) {
                holder.deleteView.setVisibility(View.GONE);
            } else {
                // if first swiped left and then swiped right
                holder.deleteView.setVisibility(View.VISIBLE);
            }

            swipe(-(int) deltaX);
            return true;
        }

        case MotionEvent.ACTION_UP:
            upX = event.getX();
            float deltaX = upX - downX;
            if (Math.abs(deltaX) > MIN_DISTANCE) {
                // left or right
                swipeRemove();
            } else {
                swipe(0);
            }

            if (listView != null) {
                listView.requestDisallowInterceptTouchEvent(false);
                motionInterceptDisallowed = false;
            }

            holder.deleteView.setVisibility(View.VISIBLE);
            return true;

        case MotionEvent.ACTION_CANCEL:
            holder.deleteView.setVisibility(View.VISIBLE);
            return false;
        }

    return true;
    }

    private void swipe(int distance) {
        View animationView = holder.mainView;
        RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams) animationView.getLayoutParams();
        params.rightMargin = -distance;
        params.leftMargin = distance;
        animationView.setLayoutParams(params);
    }

    private void swipeRemove() {
        remove(getItem(position));
        notifyDataSetChanged();
    }
}

public static class ObjectHolder {
    public LinearLayout mainView;
    public RelativeLayout deleteView;
    public RelativeLayout shareView;

    /* other views here */
}

I have also added requestDisallowInterceptTouchEvent so that ListView (which is parent) doesn't intercept the touch event when there's some amount of vertical scrolling involved.

I have written a blogpost about it which you can find it here. I have also added a Youtube video for demo.

I implemented one of these myself, but it's a bit different. I use just touch instead of swiping. Touch to open, touch to close. Here's youtube demo.

I created custom ArrayAdapter. To set the layout, I created a custom layout like this.

<RelativeLayout>
     <RelativeLayout>
          <Stuff that you want at the back of your list/>
     </RelativeLayout>
     <RelativeLayout>
          <Stuff that you want at the front of your list/>
     </RelativeLayout>
</RelativeLayout>

Using RelativeLayout, I am putting the top view over the bottom view. Both have same sizes. You can use different layouts for inner layouts.

In Custom ArrayAdapter,

@Override
public view getView(int position, View convertView, ViewGroup parent) {
    // get holder and entry
    // set each element based on entry preferences



    holder.topView.setOnClickListener(new View.OnClickListener() {

          @Override
          public void onClick(View v) {
              if (entry.isSwiped()) {
                  swipeWithAnimationValue(holder.topView, 1);
                  entry.setSwiped(false);
              } else {
                  closeOtherSwipes(entry);  // if you want to keep only one entry open at a time
                  swipeWithAnimationValue(holder.topView, 0);
                  entry.setSwiped(true);
              }
         }
   });
}

Normal Animation would not work as it just shifts the view, but it's still there so if you try to click, the click still occurs on the top view. Hence I have used valueAnimator and actually shifted those lists.

public void swipeWithAnimationValue(final View view, final int direction) {
    final int width = view.getWidth();
    Log.i(TAG, "view width = " + String.valueOf(width));
    ValueAnimator animationSwipe;
    int duration = 300;
    if (direction == 0) {
         animationSwipe = ValueAnimator.ofInt(0, view.getWidth() - 200);
    } else {
         animationSwipe = ValueAnimator.ofInt(view.getWidth() - 200, 0);
    }

    animationSwipe.setDuration(duration);
    AnimatorUpdateListener maringUpdater = new AnimatorUpdateListener() {
        @Override
        public void onAnimationUpdate(ValueAnimator animation) {

             RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams) view.getLayoutParams();
             params.rightMargin = -(Integer)animation.getAnimatedValue();
             params.leftMargin = (Integer)animation.getAnimatedValue();
             view.setLayoutParams(params);
        }
    };

    animationSwipe.addUpdateListener(maringUpdater);
    animationSwipe.setRepeatCount(0);
    animationSwipe.start();
}

Instead of using a custom ListView you can simply support "swipe" gesture on list items onTouch, like the following:

private static final int DEFAULT_THRESHOLD = 128;

row.setOnTouchListener(new View.OnTouchListener() {

    int initialX = 0;
    final float slop = ViewConfiguration.get(context).getScaledTouchSlop();

    public boolean onTouch(final View view, MotionEvent event) {
        if (event.getAction() == MotionEvent.ACTION_DOWN) {
            initialX = (int) event.getX();
            view.setPadding(0, 0, 0, 0);
        } else if (event.getAction() == MotionEvent.ACTION_MOVE) {
            int currentX = (int) event.getX();
            int offset = currentX - initialX;
            if (Math.abs(offset) > slop) {
                view.setPadding(offset, 0, 0, 0);

                if (offset > DEFAULT_THRESHOLD) {
                    // TODO :: Do Right to Left action! And do nothing on action_up.
                } else if (offset < -DEFAULT_THRESHOLD) {
                    // TODO :: Do Left to Right action! And do nothing on action_up.
                }
            }
        } else if (event.getAction() == MotionEvent.ACTION_UP || event.getAction() == MotionEvent.ACTION_CANCEL) {
            // Animate back if no action was performed.
            ValueAnimator animator = ValueAnimator.ofInt(view.getPaddingLeft(), 0);
            animator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
                @Override
                public void onAnimationUpdate(ValueAnimator valueAnimator) {
                    view.setPadding((Integer) valueAnimator.getAnimatedValue(), 0, 0, 0);
                }
            });
            animator.setDuration(150);
            animator.start();
        }
};

I also use reverse animation if no action was performed.

This solution is lightweight so you should not experience any lags.

Check out: SwipeActionAdapter

It's a great library that does exactly what you're asking for. It allows Swipe in both directions with an underlying Layout or Color. It's easy to implement and looks nice!
