how can I get the selected value of dynamically created spinner android java

Question

In my android application I have dynamically created spinners and i want to get selected value of dynamically created spinner and I am doing like below:

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_answermultitext);

String Title = "";
        for (int count = 0; count < DropDown.length; count++) {
            Title = DropDown[count].split(":")[0];
            String DValue = DropDown[count].split(":")[1];
            for (int i = 0; i < arr.length; i++) {
                if (DValue.contains(arr[i])) {
                    DValue = DValue.replace(arr[i], "");
                }
                if(Title.contains(arr[i]))
                {
                    Title = Title.replace(arr[i], "");
                }
            }
            String[] data = DValue.split(",");

            ///Creating Text View
            tv[count] = new TextView(this);
            RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(
                    (int) LayoutParams.WRAP_CONTENT,
                    (int) LayoutParams.WRAP_CONTENT);
            params.leftMargin = 25;
            params.topMargin = (count + 1) * (75 + add);
            tv[count].setText(Title);
            tv[count].setTextSize((float) 20);
            tv[count].setPadding(5, 15, 5, 15);
            tv[count].setLayoutParams(params);
            layout.addView(tv[count]);

            ///Creating Spinner
            Sp[count] = new Spinner(this);
            RelativeLayout.LayoutParams param = new RelativeLayout.LayoutParams(
                    (int) LayoutParams.WRAP_CONTENT,
                    (int) LayoutParams.WRAP_CONTENT);
            param.leftMargin = 25;
            param.topMargin = (count + 1) * (100 + add1);
            Sp[count].setPadding(5, 23, 5, 5);
            Sp[count].setLayoutParams(param);
            ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
                    android.R.layout.simple_spinner_item, data);
            adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
            Sp[count].setAdapter(adapter);
            Sp[count].setOnItemSelectedListener(new OnItemSelectedListener() {

                @Override
                public void onItemSelected(AdapterView<?> parent, View view,
                        int position, long id) {
                    // Get select item

                        int sid = Sp[count].getSelectedItemPosition();
                        // spinnerDropDown.getSelectedItem().toString();
                        Toast.makeText(getBaseContext(),
                                "You have selected : " + DropDown[sid],
                                Toast.LENGTH_SHORT).show();
                }

                // drop_SelectedVal
                @Override
                public void onNothingSelected(AdapterView<?> parent) {
                    // TODO Auto-generated method stub
                }
            });
            layout.addView(Sp[count]);
        }
}

But I am getting below error in onItemSelected() method at this line int sid = Sp[count].getSelectedItemPosition();

Cannot refer to a non-final variable count inside an inner class defined in a different method

And when I add final with the count vaiable the above error is remove and I am getting below error at this line for(int count = 0; count < DropDown.length; count++)

The final local variable count cannot be assigned. It must be blank and not using a compound assignment

kindly suggest me how can I resolve it.

waiting for reply.

Thanks

Answer 1

First of all about the error : the error is because you are accessing non-final Spinner object Sp[count] in inner class. So changing count to final will create another error but the previous problem is still not solved. Its just suppressed for time being when you will solve the error with count it will come again.

How to solve ?

First remove the final you added with the count.

Second if you want only the position of the selected item in the spinner you should do the following

  @Override
  public void onItemSelected(AdapterView<?> parent, View view,int position, long id) {
   int selectedItem = position;
  }

Third If you want to get the String selected you should do the following :

@Override
  public void onItemSelected(AdapterView<?> parent, View view,int position, long id) {
   String s = (String) parent.getItemAtPosition(position);
   // here's the change
  }

Answer 2

you can use the

int position

on onItemSelected.

@Override
public void onItemSelected(AdapterView<?> parent, View view,
int position, long id) {
       int hereIsYourSelectedItem = position;
 }
