我有这个代码，其中我有一个带有国家名称的微调器。我已经在strings.xml文件中声明了这些名称。现在，我想要的是当用户选择一个国家时，该值被发送到arraylist然后使用post参数我想执行一个xml文件。这是我的代码 - ：
public class AddBank extends Activity implements
AdapterView.OnItemSelectedListener{
EditText et1,et2,et3,et4,et5,et6,et7,et8,et9;
Spinner spinner1;
Button add;
String userpin;
TextView country;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.addbank);
Bundle gotuser= getIntent().getExtras();
userpin= gotuser.getString("username");
et1=(EditText)findViewById(R.id.editText1);
et2=(EditText)findViewById(R.id.editText2);
et3=(EditText)findViewById(R.id.editText3);

public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
country.setText(country_array[arg2]);
// TODO Auto-generated method stub
}
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
country.setText("");
}
}
现在，在检索微调器的值的方法中，我收到“country_array无法解析为变量”的错误。 请帮帮我。谢谢。

希望这可以帮到你。
Resources res = getResources();
String[] country_array = res.getStringArray(R.array.country_array);
.....
public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
country.setText(country_array[arg2]);
}

在您的活动中声明country_array：
AdapterView.OnItemSelectedListener{
EditText et1,et2,et3,et4,et5,et6,et7,et8,et9;
Spinner spinner1;
Button add;
String userpin;
TextView country;
//add this
String [] country_array;
@Override
public void onCreate(Bundle savedInstanceState) {
...
country_array = res.getStringArray(R.array.country_array);
...
}

将数组传递给数组适配器时，请使用此getResources（）。getStringArray（R.array.country_array）
