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);

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。

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。

YourAdapter yourAdapter =
            new YourAdapter (getActivity(),
                    R.layout.list_view_item,arrData);

    yourAdapter .setDropDownViewResource(R.layout.list_view_item);
    mySpinner.setAdapter(yourAdapter );


    String strCompare = "Indonesia";

    for (int i = 0; i < arrData.length ; i++){
        if(arrData[i].getCode().equalsIgnoreCase(strCompare)){
                int spinnerPosition = yourAdapter.getPosition(arrData[i]);
                mySpinner.setSelection(spinnerPosition);
        }
    }

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!
