How to get String from setOnItemSelectedListener method?

Question

I'm new to Android and I'm trying to get a String from spinner. I've made some research but I couldn't find anything useful. Without trying to get String the code is working properly. This is the code which is working:

assert staticSpinner2 != null;
    staticSpinner2.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {

            String spinnerLanguage2 = staticSpinner2.getSelectedItem().toString();

        }

        public String getSpin(String spinnerLanguage2) {
            return spinnerLanguage2;
        }

        @Override
        public void onNothingSelected(AdapterView<?> parent) {

        }
    });

I tried to use a getter method as follows where I didn't get any errors:

assert staticSpinner2 != null;
    staticSpinner2.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {

            String spinnerLanguage2 = staticSpinner2.getSelectedItem().toString();

        }

        public String getSpinnerString(String spinnerLanguage2) {
            return spinnerLanguage2;
        }

        @Override
        public void onNothingSelected(AdapterView<?> parent) {

        }
    });

I'm trying to set this String to a text view using:

assert staticSpinner2 != null;
    staticSpinner2.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {

            String spinnerLanguage2 = staticSpinner2.getSelectedItem().toString();

        }

        public String getSpinnerString(String spinnerLanguage2) {
            return spinnerLanguage2;
        }

        @Override
        public void onNothingSelected(AdapterView<?> parent) {

        }
    });

    MainActivityClassName AnObject = new MainActivityClassName();
    text.setText(AnObject.getSpinnerString());

Where I get an error saying "cannot resolve method getSpin()". I do realise I'm not passing any parameters to the method but I don't know how I can do it here. I appreciate any help or any other advice to solve the problem in a different way. Thanks in advance.

This is the full code if that helps:

public class MainActivity extends AppCompatActivity {

TextView text;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_json);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

    text = (TextView) findViewById(R.id.textView);

    // spinner 1
    final Spinner staticSpinner1 = (Spinner) findViewById(R.id.spinner1);

    // Create an ArrayAdapter using the string array and a default spinner
    ArrayAdapter<CharSequence> staticAdapter1 = ArrayAdapter
            .createFromResource(this, R.array.lang,
                    android.R.layout.simple_spinner_item);

    // Specify the layout to use when the list of choices appears
    staticAdapter1
            .setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

    // Apply the adapter to the spinner
    staticSpinner1.setAdapter(staticAdapter1);



    // spinner 2
    final Spinner staticSpinner2 = (Spinner) findViewById(R.id.spinner2);

    staticSpinner1.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {


        @Override
        public void onItemSelected(AdapterView<?> arg0, View arg1,
                                   int arg2, long arg3) {
            String spinnerLanguage = staticSpinner1.getSelectedItem().toString();


            switch (spinnerLanguage) {
                case "Afrikaans":
                    // Create an ArrayAdapter using the string array and a default spinner
                    ArrayAdapter<CharSequence> staticAdapterAF = ArrayAdapter
                            .createFromResource(getBaseContext(), R.array.af,
                                    android.R.layout.simple_spinner_item);

                    // Specify the layout to use when the list of choices appears
                    staticAdapterAF
                            .setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

                    // Apply the adapter to the spinner
                    staticSpinner2.setAdapter(staticAdapterAF);
                    break;
                case "French":
                    // Create an ArrayAdapter using the string array and a default spinner
                    ArrayAdapter<CharSequence> staticAdapterFR = ArrayAdapter
                            .createFromResource(getBaseContext(), R.array.fr,
                                    android.R.layout.simple_spinner_item);

                    // Specify the layout to use when the list of choices appears
                    staticAdapterFR
                            .setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

                    // Apply the adapter to the spinner
                    staticSpinner2.setAdapter(staticAdapterFR);
                    break;
                case "English":
                    // Create an ArrayAdapter using the string array and a default spinner
                    ArrayAdapter<CharSequence> staticAdapterEN = ArrayAdapter
                            .createFromResource(getBaseContext(), R.array.en,
                                    android.R.layout.simple_spinner_item);

                    // Specify the layout to use when the list of choices appears
                    staticAdapterEN
                            .setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

                    // Apply the adapter to the spinner
                    staticSpinner2.setAdapter(staticAdapterEN);
                    break;
                case "Turkish":
                    // Create an ArrayAdapter using the string array and a default spinner
                    ArrayAdapter<CharSequence> staticAdapterTR = ArrayAdapter
                            .createFromResource(getBaseContext(), R.array.tr,
                                    android.R.layout.simple_spinner_item);

                    // Specify the layout to use when the list of choices appears
                    staticAdapterTR
                            .setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

                    // Apply the adapter to the spinner
                    staticSpinner2.setAdapter(staticAdapterTR);
                    break;
            }

        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {

        }

    });


    assert staticSpinner2 != null;
    staticSpinner2.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {

            String spinnerLanguage2 = staticSpinner2.getSelectedItem().toString();


        }

        public String getSpin(String spinnerLanguage2) {
            return spinnerLanguage2;
        }

        @Override
        public void onNothingSelected(AdapterView<?> parent) {

        }
    });

    MainActivity AnObject = new MainActivity();
    text.setText(AnObject.getSpinnerString());

}

}

Answer 1

You can do this:

String selectedText = null;

staticSpinner2.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
    @Override
    public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {

        selectedText = parent.getItemAtPosition(position).toString();
    }

    @Override
    public void onNothingSelected(AdapterView<?> parent) {

    }
});

Now you can use the selectedText variable to pass on to whatever method you want. But, keep in mind, unless you select something in the spinner, it's value would be null.

Answer 2

If you really have to use it outer, you can do this :

 public void setTextView(String text){
        text.setText(text);
 }

and call this method inside your onItemSelected:

@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
     setTextView(staticSpinner2.getSelectedItem().toString());
}
