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();
    }

这是我的解决方案

List<Country> list = CountryBO.GetCountries(0);
CountriesAdapter dataAdapter = new CountriesAdapter(this,list);
dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spnCountries.setAdapter(dataAdapter);
spnCountries.setSelection(dataAdapter.getItemIndexById(userProfile.GetCountryId()));

和下面的getItemIndexById

public int getItemIndexById(String id) {
    for (Country item : this.items) {
        if(item.GetId().toString().equals(id.toString())){
            return this.items.indexOf(item);
        }
    }
    return 0;
}

希望这对你有所帮助!

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。

非常简单，只需使用getSelectedItem();

eg :

ArrayAdapter<CharSequence> type=ArrayAdapter.createFromResource(this,R.array.admin_typee,android.R.layout.simple_spinner_dropdown_item);
        type.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        mainType.setAdapter(type);

String group=mainType.getSelectedItem().toString();

上述方法返回一个字符串值

在上面的R.array。Admin_type是值中的字符串资源文件

只需在值>>字符串中创建一个.xml文件

你也可以用这个，

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

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

}
