你也可以用这个，

String[] baths = getResources().getStringArray(R.array.array_baths);
mSpnBaths.setSelection(Arrays.asList(baths).indexOf(value_here));

根据Merrill的回答 下面是如何使用CursorAdapter

CursorAdapter myAdapter = (CursorAdapter) spinner_listino.getAdapter(); //cast
    for(int i = 0; i < myAdapter.getCount(); i++)
    {
        if (myAdapter.getItemId(i) == ordine.getListino() )
        {
            this.spinner_listino.setSelection(i);
            break;
        }
    }

如果将XML数组设置为XML布局中的旋转器，则可以做到这一点

final Spinner hr = v.findViewById(R.id.chr);
final String[] hrs = getResources().getStringArray(R.array.hours);
if(myvalue!=null){
   for (int x = 0;x< hrs.length;x++){
      if(myvalue.equals(hrs[x])){
         hr.setSelection(x);
      }
   }
}

如果你需要在任何旧的适配器上有一个indexOf方法(并且你不知道底层实现)，那么你可以使用这个:

private int indexOf(final Adapter adapter, Object value)
{
    for (int index = 0, count = adapter.getCount(); index < count; ++index)
    {
        if (adapter.getItem(index).equals(value))
        {
            return index;
        }
    }
    return -1;
}

为了让应用程序记住最后选择的微调值，你可以使用下面的代码:

Below code reads the spinner value and sets the spinner position accordingly. public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); int spinnerPosition; Spinner spinner1 = (Spinner) findViewById(R.id.spinner1); ArrayAdapter<CharSequence> adapter1 = ArrayAdapter.createFromResource( this, R.array.ccy_array, android.R.layout.simple_spinner_dropdown_item); adapter1.setDropDownViewResource(android.R.layout.simple_list_item_activated_1); // Apply the adapter to the spinner spinner1.setAdapter(adapter1); // changes to remember last spinner position spinnerPosition = 0; String strpos1 = prfs.getString("SPINNER1_VALUE", ""); if (strpos1 != null || !strpos1.equals(null) || !strpos1.equals("")) { strpos1 = prfs.getString("SPINNER1_VALUE", ""); spinnerPosition = adapter1.getPosition(strpos1); spinner1.setSelection(spinnerPosition); spinnerPosition = 0; } And put below code where you know latest spinner values are present, or somewhere else as required. This piece of code basically writes the spinner value in SharedPreferences. Spinner spinner1 = (Spinner) findViewById(R.id.spinner1); String spinlong1 = spinner1.getSelectedItem().toString(); SharedPreferences prfs = getSharedPreferences("WHATEVER", Context.MODE_PRIVATE); SharedPreferences.Editor editor = prfs.edit(); editor.putString("SPINNER1_VALUE", spinlong1); editor.commit();

你必须传递你的自定义适配器的位置，如REPEAT[position]。它能正常工作。
