Disable Swipe for position in RecyclerView using ItemTouchHelper.SimpleCallback

Question

I am using recyclerview 22.2.0 and the helper class ItemTouchHelper.SimpleCallback to enable swipe-to-dismiss option to my list. But as I have a type of header on it, I need to disable the swipe behavior for the first position of the adapter. As RecyclerView.Adapter doesn't have a isEnabled() method, I tried to disable the view interaction through the methods isEnabled() and isFocusable() in the ViewHolder creation itself, but had no success. I tried to adjust the swipe threshold to a full value, like 0f ot 1f in the SimpleCallback's method getSwipeThreshold(), but no success too.

Some fragments of my code to help you to help me.

My Activity:

@Override protected void onCreate(Bundle bundle) {     //... initialization     ItemTouchHelper.SimpleCallback simpleItemTouchCallback = new ItemTouchHelper.SimpleCallback(0,             ItemTouchHelper.LEFT | ItemTouchHelper.RIGHT) {          @Override         public boolean onMove(RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder,                           RecyclerView.ViewHolder target) {             return false;         }          @Override         public float getSwipeThreshold(RecyclerView.ViewHolder viewHolder) {             if (viewHolder instanceof CartAdapter.MyViewHolder) return 1f;             return super.getSwipeThreshold(viewHolder);         }          @Override         public void onSwiped(RecyclerView.ViewHolder viewHolder, int swipeDir) {          }     };      ItemTouchHelper itemTouchHelper = new ItemTouchHelper(simpleItemTouchCallback);     itemTouchHelper.attachToRecyclerView(recyclerView); } 

And I have a common adapter with two view types. In the ViewHolder that I want to disable swiping, I did:

public static class MyViewHolder extends RecyclerView.ViewHolder {     public ViewGroup mContainer;      public MyViewHolder(View v) {         super(v);         v.setFocusable(false);         v.setEnabled(false);         mContainer = (ViewGroup) v.findViewById(R.id.container);           } } 

Answer 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) }
