因为我需要一些东西，这也适用于本地化，我想出了以下两种方法:

    private int getArrayPositionForValue(final int arrayResId, final String value) {
        final Resources english = Utils.getLocalizedResources(this, new Locale("en"));
        final List<String> arrayValues = Arrays.asList(english.getStringArray(arrayResId));

        for (int position = 0; position < arrayValues.size(); position++) {
            if (arrayValues.get(position).equalsIgnoreCase(value)) {
                return position;
            }
        }
        Log.w(TAG, "getArrayPosition() --> return 0 (fallback); No index found for value = " + value);
        return 0;
    }

如您所见，我还遇到了arrays.xml和我要比较的值之间的大小写敏感性的额外复杂性。 如果你没有这个，上面的方法可以简化为:

返回arrayValues.indexOf(价值);

静态助手方法

public static Resources getLocalizedResources(Context context, Locale desiredLocale) {
        Configuration conf = context.getResources().getConfiguration();
        conf = new Configuration(conf);
        conf.setLocale(desiredLocale);
        Context localizedContext = context.createConfigurationContext(conf);
        return localizedContext.getResources();
    }

基于值设置微调器的一个简单方法是

mySpinner.setSelection(getIndex(mySpinner, myValue));

 //private method of your class
 private int getIndex(Spinner spinner, String myString){
     for (int i=0;i<spinner.getCount();i++){
         if (spinner.getItemAtPosition(i).toString().equalsIgnoreCase(myString)){
             return i;
         }
     }

     return 0;
 } 

复杂代码的方法已经有了，这只是简单得多。

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

}

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;
}
