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 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;
        }
    }

你可以使用这种方式，只是让你的代码更简单、更清晰。

ArrayAdapter<String> adapter = (ArrayAdapter<String>) spinnerCountry.getAdapter();
int position = adapter.getPosition(obj.getCountry());
spinnerCountry.setSelection(position);

希望能有所帮助。

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);

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。

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!
