Both direction swipes with limited swipe amount

[iamtodor]

Hi! Is there a way to make the same behaviour like demo_s has but with left and right item pinned? I mean I have left and right buttons, which should get a show like your demo has.

Here the code, which I used as example: https://github.com/h6ah4i/android-advancedrecyclerview/blob/master/example/src/main/java/com/h6ah4i/android/example/advrecyclerview/demo_s_button/SwipeableWIthButtonExampleAdapter.java

Here is mine adapter with a few changes: https://gist.github.com/Iamtodor/49528adda131c13d2c716d20f3821f29

Here the screen how it should looks like:

Faced the same problem. Is there a way to implement both direction swipes with limited swipe amount?

@Iamtodor, @kostya17 Hi. I will show you small code snippets which helps you to implement such behavior with this library. (Sorry, I have not time to create a full example code on week days...)

---

First, look at the adapter implementation of the "Button under swipeable item" demo. This demo app allows left direction swipe only.

• https://github.com/h6ah4i/android-advancedrecyclerview/blob/0.8.7/example/src/main/java/com/h6ah4i/android/example/advrecyclerview/demo_s_button/SwipeableWIthButtonExampleAdapter.java

1. Change isPinned() method of each item data

// this method return whether the item is pinned or not
boolean isPinned();
👇
// this method returns NOT_PINNED(=0), PINNED_LEFT(=1) or PINNED_RIGHT(=2)
int getPinnedState();

2. Modify onBindItemView() method of the adapter

public void onBindViewHolder(MyViewHolder holder, int position) {
    ...
    holder.setMaxLeftSwipeAmount(-0.5f);
    holder.setMaxRightSwipeAmount(0);
    holder.setSwipeItemHorizontalSlideAmount(
            item.isPinned() ? -0.5f : 0);
}
👇
public void onBindViewHolder(MyViewHolder holder, int position) {
    ...
    holder.setMaxLeftSwipeAmount(-0.7f);
    holder.setMaxRightSwipeAmount(0.7f);
    switch (item.getPinnedState()) {
    case PINNED_LEFT:
        holder.setSwipeItemHorizontalSlideAmount(-0.7f);
        break;
    case PINNED_RIGHT:
        holder.setSwipeItemHorizontalSlideAmount(0.7f);
        break;
    default:
        holder.setSwipeItemHorizontalSlideAmount(0);
        break;
    }
}

3. Modify the onSwipeItem() method of the adapter

@Override
public SwipeResultAction onSwipeItem(MyViewHolder holder, int position, int result) {
    switch (result) {
        case Swipeable.RESULT_SWIPED_LEFT:
            return new SwipeLeftResultAction(this, position);
        case Swipeable.RESULT_SWIPED_RIGHT:
        case Swipeable.RESULT_CANCELED:
        default:
            if (position != RecyclerView.NO_POSITION) {
                return new UnpinResultAction(this, position);
            } else {
                return null;
            }
    }
}
👇
@Override
public SwipeResultAction onSwipeItem(MyViewHolder holder, int position, int result) {
    switch (result) {
        case Swipeable.RESULT_SWIPED_LEFT:
            return new SwipePinnedResultAction(this, position, PINNED_LEFT);
        case Swipeable.RESULT_SWIPED_RIGHT:
            return new SwipePinnedResultAction(this, position, PINNED_RIGHT);
        case Swipeable.RESULT_CANCELED:
        default:
            if (position != RecyclerView.NO_POSITION) {
                return new UnpinResultAction(this, position);
            } else {
                return null;
            }
    }
}

4. Convert SwipeLeftResultAction to SwipePinnedResultAction

private static class SwipeLeftResultAction extends SwipeResultActionMoveToSwipedDirection {
    ...
}
👇
private static class SwipePinnedResultAction extends SwipeResultActionMoveToSwipedDirection {
    private SwipeableWIthButtonExampleAdapter mAdapter;
    private final int mPosition;
    private final int mPinnedState;
    private boolean mSetPinned;

    SwipePinnedResultAction(SwipeableWIthButtonExampleAdapter adapter, int position, int pinnedState) {
        mAdapter = adapter;
        mPosition = position;
        mPinnedState = pinnedState;
    }

    @Override
    protected void onPerformAction() {
        super.onPerformAction();

        AbstractDataProvider.Data item = mAdapter.mProvider.getItem(mPosition);

        if (item.getPinnedState() == NOT_PINNED) {
            item.setPinnedState(mPinnedState);
            mAdapter.notifyItemChanged(mPosition);
            mSetPinned = true;
        }
    }

    ...
}

@h6ah4i Thank you, buddy. It works great!

@h6ah4i hello. Can you update example for last library version?
