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();

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

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。

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);

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);
        }
    }

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。
