你也可以用这个，

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

我在Spinners中保留了一个单独的数组列表。这样我就可以在数组列表上执行indexOf，然后使用该值在Spinner中设置选择。

I had the same issue when trying to select the correct item in a spinner populated using a cursorLoader. I retrieved the id of the item I wanted to select first from table 1 and then used a CursorLoader to populate the spinner. In the onLoadFinished I cycled through the cursor populating the spinner's adapter until I found the item that matched the id I already had. Then assigned the row number of the cursor to the spinner's selected position. It would be nice to have a similar function to pass in the id of the value you wish to select in the spinner when populating details on a form containing saved spinner results.

@Override
public void onLoadFinished(Loader<Cursor> loader, Cursor cursor) {  
  adapter.swapCursor(cursor);

  cursor.moveToFirst();

 int row_count = 0;

 int spinner_row = 0;

  while (spinner_row < 0 || row_count < cursor.getCount()){ // loop until end of cursor or the 
                                                             // ID is found 

    int cursorItemID = bCursor.getInt(cursor.getColumnIndexOrThrow(someTable.COLUMN_ID));

    if (knownID==cursorItemID){
    spinner_row  = row_count;  //set the spinner row value to the same value as the cursor row 

    }
cursor.moveToNext();

row_count++;

  }

}

spinner.setSelection(spinner_row ); //set the selected item in the spinner

}

以下是我的完整解决方案。我有以下enum:

public enum HTTPMethod {GET, HEAD}

用于后续课程

public class WebAddressRecord {
...
public HTTPMethod AccessMethod = HTTPMethod.HEAD;
...

使用HTTPMethod enum-member设置微调器的代码:

    Spinner mySpinner = (Spinner) findViewById(R.id.spinnerHttpmethod);
    ArrayAdapter<HTTPMethod> adapter = new ArrayAdapter<HTTPMethod>(this, android.R.layout.simple_spinner_item, HTTPMethod.values());
    mySpinner.setAdapter(adapter);
    int selectionPosition= adapter.getPosition(webAddressRecord.AccessMethod);
    mySpinner.setSelection(selectionPosition);

其中R.id.spinnerHttpmethod定义在布局文件中，而android.R.layout. httpmethod定义在布局文件中。Simple_spinner_item由android-studio下发。

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);
      }
   }
}
