I have visited How to update RecyclerView Adapter Data?

There is a list of providers on the signup page all the providers are coming from an API of providers. there is an array list named providers there is also a spinner item named signupspinner2 and a String variable listType. this is the chunk of code

signuppageText6.setText("Providers");
                listType="PROVIDERS";

                signuppageSpinner2.setAdapter(new ArrayAdapter<String> 
   (SignUp.this,android.R.layout.simple_spinner_dropdown_item,providers));

                signuppageSpinner2.setOnItemSelectedListener(SignUp.this);


                signuppageSignUpButton.setClickable(true);
                Log.i("providers",providers.toString());

now the problem is the data in my array adapter is repeating and which it should not be. I know the best possible thing I can do is to update the adapter values and the command is:

          adapter.notifyDataSetChanged();

but since this is not my code I am a bit confused about what could be done if someone could help me I would be grateful.

  • I got the solution and my problem is resolved !! the issue was in my class only as I was calling a function twice. I debugged the code thoroughly and found it. Thanks for visiting . – Paritosh purohit Jul 03 '20 at 08:39
