Answer 1

private void selectSpinnerValue(Spinner spinner, String myString)
     {
         int index = 0;
         for(int i = 0; i < spinner.getCount(); i++){
             if(spinner.getItemAtPosition(i).toString().equals(myString)){
                 spinner.setSelection(i);
                 break;
             }
         }
     }

Answer 2

try this. it will work fine.

int position = adapter.getPosition(value);
spinner.setSelection(position);

Answer 3

You have to take one more string array for selected country respective value :

<string-array name="country">
   <item>India</item>
</string-array>

<string-array name="country_value">
  <item>91</item>
</string-array>

Initialize value array :

String[] countryValue = getResources().getStringArray(R.array.country_value);

Get spinner selected item respective value from value array:

selectionarea = countryValue[position];

Check Example : accessing item name in string-array (Android)

Answer 4

for(int i = 0; i < country.getCount(); i++){
    if(country.getItemAtPosition(i).toString().equals("yourString")){
        country.setSelection(i);
        break;
    }
}

You could also solve it by this way, by specifiying the String you are searching for instead if you have access to it. Otherwise, you will have to follow Haresh Chhelana's approach.

Answer 5

您始终可以覆盖getItemId(int position)以返回值，而不是默认的位置ID
