how to get position or index of element in spinner

I have a spinner in my code and I want to get position of element in the array when selected. Here is my code which is running perfectly. In selection I am storing the string value of element but I also want the position count of element

public class MainActivity extends Activity implements OnItemSelectedListener {
    final Context context = this;
    private Button button;
    private String selection;
    private String[] states  = new String[]{
            "Gujrat","Jammu and Kashmir","Kerala","Karnataka","Lakshadweep","Maharashtra","Manipur","Mizoram",
            "Nagaland","New Delhi","Rajasthan","Tami Nadu","West Bengal"
    };
    ArrayList<String> categoryList = new ArrayList<String>();
    private static final String TAG = "MyActivity";
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        int currentMonth = Calendar.getInstance().get(Calendar.MONTH)+1;

        //make it fullscreen
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);

        //fix portrait orientation
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

        setContentView(R.layout.activity_main);
        ImageView img = (ImageView)findViewById(R.id.imageView1);
        img.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {

                // custom dialog
                final Dialog dialog = new Dialog(MainActivity.this);
                dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
                dialog.setContentView(R.layout.menu);
                Button dialogButton = (Button) dialog.findViewById(R.id.btncross);
                // if button is clicked, close the custom dialog
                dialogButton.setOnClickListener(new OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        dialog.dismiss();
                    }
                });

                dialog.show();
                Spinner spin = (Spinner)dialog.findViewById(R.id.spinState);
                ArrayAdapter<String> adapter_state = new ArrayAdapter<String>(MainActivity.this,  android.R.layout.simple_spinner_item, states);
                adapter_state.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
                spin.setAdapter(adapter_state);

                spin.setOnItemSelectedListener(MainActivity.this);
            }
        });



    }
    @Override
    public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2,
                               long arg3) {
        // TODO Auto-generated method stub
        TextView tv = (TextView)arg1;
        selection = tv.getText().toString();
        Log.v(TAG, "index=" + selection);

    }
    @Override
    public void onNothingSelected(AdapterView<?> arg0) {
        // TODO Auto-generated method stub

    }

}

Here in your setOnItemSelectedListener(new OnItemSelectedListener() 

public abstract void onItemSelected (AdapterView<?> parent, View view, int position, long id)

Parameters

  1. parent The AdapterView where the selection happened

  2. view The view within the AdapterView that was clicked

  3. position The position of the view in the adapter

  4. id The row id of the item that is selected

int arg2 to get Selected Item Id

Update only this method,

@Override
public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
    // TODO Auto-generated method stub
    Log.v(TAG, "index=" + spin.getItemIdAtPosition(int2));
}

int arg2 of `onItemSelected()` is the position of selected items.

So you can use it like 

@Override
public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2,
                           long arg3) {
    // TODO Auto-generated method stub

    selection = states[arg2];
    Log.v(TAG, "index=" + arg2);
    Log.v(TAG, "selction=" + selection);

}

In the code:

@Override
public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2,
                           long arg3) {
    // TODO Auto-generated method stub
    TextView tv = (TextView)arg1;
    selection = tv.getText().toString();
    Log.v(TAG, "index=" + selection);

}

arg2 is the position of spinner
