Installation

dependencies {

}

Usages

mCallback = new ItemTouchHelperCallback();
mItemTouchHelper = new ItemTouchHelperExtension(mCallback);
mItemTouchHelper.attachToRecyclerView(mRecyclerView);

ItemTouchHelperCallback just set as Itemtouchhelper. Set your swipe content view translationX by moving in method onChildDraw

public class ItemTouchHelperCallback extends ItemTouchHelperExtension.Callback {

    @Override
    public int getMovementFlags(RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder) {
        return makeMovementFlags(0, ItemTouchHelper.START);
    }

    @Override
    public boolean onMove(RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder, RecyclerView.ViewHolder target) {
        return false;
    }
    
    ...

    @Override
    public void onChildDraw(Canvas c, RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder, float dX, float dY, int actionState, boolean isCurrentlyActive) {
        MainRecyclerAdapter.ItemBaseViewHolder holder = (MainRecyclerAdapter.ItemBaseViewHolder) viewHolder;
        holder.mViewContent.setTranslationX(dX);
    }
}

At last you can let your viewholder implements Extension to set swipe settling width

@Override
public float getActionWidth() {
    return mActionContainer.getWidth();
}

This will use whole recyclerview width when you do not add the width

  @Override
    public void onChildDraw(Canvas c, RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder, float dX, float dY, int actionState, boolean isCurrentlyActive) {
        if (dY != 0 && dX == 0) super.onChildDraw(c, recyclerView, viewHolder, dX, dY, actionState, isCurrentlyActive);
       ...
    }
