Disable Swipe for position in RecyclerView using ItemTouchHelper.SimpleCallback

Solution 1:

After playing a bit, I managed that SimpleCallback has a method called getSwipeDirs(). As I have a specific ViewHolder for the not swipable position, I can make use of instanceof to avoid the swipe. If that's not your case, you can perform this control using the position of ViewHolder in the Adapter.

Java

@Override
public int getSwipeDirs(RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder) {
    if (viewHolder instanceof CartAdapter.MyViewHolder) return 0;
    return super.getSwipeDirs(recyclerView, viewHolder);
}

Kotlin

override fun getSwipeDirs (recyclerView: RecyclerView, viewHolder: RecyclerView.ViewHolder): Int {
    if (viewHolder is CartAdapter.MyViewHolder) return 0
    return super.getSwipeDirs(recyclerView, viewHolder)
}

Solution 2:

If someone is using ItemTouchHelper.Callback. Then You can remove any related flags in getMovementFlags(..) function.

@Override
public int getMovementFlags(RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder) {
    int dragFlags = ItemTouchHelper.UP | ItemTouchHelper.DOWN;
    int swipeFlags = ItemTouchHelper.START | ItemTouchHelper.END;
    return makeMovementFlags(dragFlags, swipeFlags);
}

Here instead of dragFlags and swipeFlags You can pass 0 to disable corresponding feature.

ItemTouchHelper.START means swiping left to right in case of left to right locale (LTR application Support), but the other way around in a right to left locale (RTL application Support). ItemTouchHelper.END means swiping in the opposite direction of START.

so you can remove any flag according to your requirements.

Solution 3:

Here's a simple way to do this that only depends upon the position of the item being swiped:

@Override
public int getMovementFlags(RecyclerView recyclerView, RecyclerView.ViewHolder holder) {
    int position = holder.getAdapterPosition();
    int dragFlags = 0; // whatever your dragFlags need to be
    int swipeFlags = createSwipeFlags(position)

    return makeMovementFlags(dragFlags, swipeFlags);
}

private int createSwipeFlags(int position) {
  return position == 0 ? 0 : ItemTouchHelper.START | ItemTouchHelper.END;
}

This should also work if you're using SimpleCallback:

@Override
public int getSwipeDirs(RecyclerView recyclerView, RecyclerView.ViewHolder holder) {
    int position = holder.getAdapterPosition();
    return createSwipeFlags(position);
}

private int createSwipeFlags(int position) {
  return position == 0 ? 0 : super.getSwipeDirs(recyclerView, viewHolder);
}

If you want to disable swiping conditional upon the data in the item, use the position value to get data from the adapter for the item being swiped and disable accordingly.

If you already have specific holder types which need to not swipe, the accepted answer will work. However, creating holder types as a proxy for position is a kludge and should be avoided.

Solution 4:

There are a few ways to go about this, but if you only have one ViewHolder, but more than one layout you can take this approach.

Override the getItemViewType and give it some logic as to determine view type based on position or type of data in object (I have a getType function in my object)

@Override
public int getItemViewType(int position) {
    return data.get(position).getType;
}

Return proper layout in onCreateView based on ViewType (Make sure to pass view type to ViewHolder class.

@Override
public AppListItemHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    mContext = parent.getContext();

    if (viewType == 0){
        return new AppListItemHolder(LayoutInflater.from(mContext).inflate(R.layout.layout, parent, false), viewType);
    else
        return new AppListItemHolder(LayoutInflater.from(mContext).inflate(R.layout.header, parent, false), viewType);
    }
}

Get the content views of the different layouts based on view type public static class AppListItemHolder extends RecyclerView.ViewHolder {

    public AppListItemHolder (View v, int viewType) {
        super(v);

        if (viewType == 0)
            ... get your views contents
        else
            ... get other views contents
        }
    }
}

And then in your ItemTouchHelper change actions based on ViewType. For me this disables swiping of a RecyclerView section header

@Override
public int getSwipeDirs(RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder) {
    if (viewHolder.getItemViewType() == 1) return 0;
        return super.getSwipeDirs(recyclerView, viewHolder);
    }
}

Solution 5:

First in recyclerView at onCreateViewHolder method, set tag for each viewHolder type, like below code:

@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup viewGroup, int viewType) {
    if(ITEM_TYPE_NORMAL == viewType) {
        View v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.deposite_card_view, viewGroup, false);
        ItemViewHolder holder = new ItemViewHolder(context, v);
        holder.itemView.setTag("normal");
        return holder;
    } else {
        View v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.card_header, viewGroup, false);
        HeaderViewHolder holder = new HeaderViewHolder(context, v);
        holder.itemView.setTag("header");
        return holder;
    }
} 

then in ItemTouchHelper.Callback implementation, update getMovementFlags method, like below:

public class SwipeController extends ItemTouchHelper.Callback {

@Override
public int getMovementFlags(RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder) {
    if("normal".equalsIgnoreCase((String) viewHolder.itemView.getTag())) {
        return makeMovementFlags(0, LEFT | RIGHT);
    } else {
        return 0;
    }
}

at end attach to recyclerView:

final SwipeController swipeController = new SwipeController();

    ItemTouchHelper itemTouchHelper = new ItemTouchHelper(swipeController);
    itemTouchHelper.attachToRecyclerView(recyclerView);
