Return value of string 3

Question

I want to return the value of choice in String prodName[] but I always got the value of choice is always null please help sorry for my bad English.

String prodName[]={choice};
int Quantity[] = {};
int Total[]={};
String Price[]={choice} ;

@Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    ArrayAdapter<CharSequence> badapter = ArrayAdapter.createFromResource(
                                              this,
                                              R.array.products,
                                              android.R.layout.simple_spinner_dropdown_item);
    listView = (ListView) findViewById(R.id.list1);
    button = (Button) findViewById(R.id.button);
    spinner = (Spinner)findViewById(R.id.spinner);
    badapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    spinner.setAdapter(badapter);


    final MyAdapter adapter = new MyAdapter(this, prodName, Price);
    //set the adapter
    listView.setAdapter(adapter);
    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            String sample;

            choice = spinner.getSelectedItem().toString();
            prodName = choice.split(choice);

        }
    });

}

I believe your problem is related to your use of the java array. https://stackoverflow.com/a/13197760/8560690 — Jantzilla, Dec 05 '18 at 04:38

I guess you're using split() method in the wrong way.

String demo = "1,2,3,4";
String[] splitted = demo.split(",");  //splitted will be an array containing 4 elements [1, 2, 3, 4]

Now I guess you know what the split() method does. :)

Since you already got the selected item text as String in the variable choice. why are you calling split() method on it?

You can find more about the split() method here

String[] prodName={choice};
