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。

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();
    }

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();

根据Merrill的回答，我想出了这个单线解决方案……它不是很漂亮，但是你可以责怪那些维护Spinner代码的人忽略了包含一个这样做的函数。

mySpinner.setSelection(((ArrayAdapter<String>)mySpinner.getAdapter()).getPosition(myString));

你会得到一个警告，关于ArrayAdapter<String>的强制转换是如何未选中的…实际上，您可以像Merrill那样使用ArrayAdapter，但这只是将一个警告交换为另一个警告。

如果警告导致问题，只需添加

@SuppressWarnings("unchecked")

到方法签名或语句之上。

下面是如何做到这一点，如果你使用SimpleCursorAdapter(其中columnName是你用来填充你的spinner的db列的名称):

private int getIndex(Spinner spinner, String columnName, String searchString) {

    //Log.d(LOG_TAG, "getIndex(" + searchString + ")");

    if (searchString == null || spinner.getCount() == 0) {

        return -1; // Not found
    }
    else {

        Cursor cursor = (Cursor)spinner.getItemAtPosition(0);

        int initialCursorPos = cursor.getPosition(); //  Remember for later

        int index = -1; // Not found
        for (int i = 0; i < spinner.getCount(); i++) {

            cursor.moveToPosition(i);
            String itemText = cursor.getString(cursor.getColumnIndex(columnName));

            if (itemText.equals(searchString)) {
                index = i; // Found!
                break;
            }
        }

        cursor.moveToPosition(initialCursorPos); // Leave cursor as we found it.

        return index;
    }
}

同样(对Akhil的回答进行了细化)，如果你从数组中填充你的Spinner，这是相应的方法:

private int getIndex(Spinner spinner, String searchString) {

    if (searchString == null || spinner.getCount() == 0) {

        return -1; // Not found

    }
    else {

        for (int i = 0; i < spinner.getCount(); i++) {
            if (spinner.getItemAtPosition(i).toString().equals(searchString)) {
                return i; // Found!
            }
        }

        return -1; // Not found
    }
};

如果你使用字符串数组，这是最好的方法:

int selectionPosition= adapter.getPosition("YOUR_VALUE");
spinner.setSelection(selectionPosition);
