Searchview - hide toast that appears when a key is pressed

I am using SearchView filter. Everything works fine, but when you leave the keyboard to type and press the button, a toast is displayed. Does anyone know how to remove it?

My code:

    searchView = (SearchView) view.findViewById(R.id.buscador_lineas_transporte);
    searchView.setOnQueryTextListener(new OnQueryTextListener() {

        @Override
        public boolean onQueryTextSubmit(String query) {
            return false;
        }

        @Override
        public boolean onQueryTextChange(String newText) {
            if(TextUtils.isEmpty(newText)){
                lvLineasTransporte.clearTextFilter();
            }
            else{
                lvLineasTransporte.setFilterText(newText);
            }

            return true;
        }
    });

      

        
        
        
      

    

Thank.

This keyboard appears when you implement the Filterable interface in the adapter.
