如何按值设置Spinner的选定项目,而不是按位置设置

Question

<item value="245">Guinea-Bissau [245]</item >
<item value="592">Guyana [592]</item >
<item value="509">Haiti  [509]</item >
<item value="504">Honduras [504]</item >
<item value="91">India [91]</item >
<item value="62">Indonesia [62]</item >

我正在使用这个

country.setOnItemSelectedListener(new OnItemSelectedListener() {

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

        // TODO Auto-generated method stub
        //selectioncountry = parent.getItemAtPosition(position).toString();
        selectionarea = parent.getItemIdAtPosition(position);
    }

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

        // TODO Auto-generated method stub          
    }
});

这个代码给印度的价值是4但我需要91我怎么能这样做???

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;
             }
         }
     }
