在Android中創建日期選擇器時出錯？

Question

我而創造的Android "Syntax error on tokens, AnnotationName expected instead"

public class Insert extends Activity { 

    private Header header; 
    private EditText etName; 
    private EditText etAge; 
    private TextView mDateDisplay; 
    private Button mPickDate; 
    private int mYear; 
    private int mMonth; 
    private int mDay; 

    static final int DATE_DIALOG_ID = 0; 
    private static final int ID_DATEPICKER = 0; 

    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) 
    { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.insert); 

     header = (Header) findViewById(R.id.layoutHeader); 
     header.init(); 

     etName = (EditText) findViewById(R.id.et_name); 
     etAge = (EditText) findViewById(R.id.et_age); 


     Button datePickerButton = (Button)findViewById(R.id.pickDate); 
     datePickerButton.setOnClickListener(datePickerButtonOnClickListener); 
    } 

    private Button.OnClickListener datePickerButtonOnClickListener= new Button.OnClickListener() 
    { 

    @Override 
    public void onClick(View v) 
    { 
    // TODO Auto-generated method stub 
    final Calendar c = Calendar.getInstance(); 
    myYear = c.get(Calendar.YEAR); 
    myMonth = c.get(Calendar.MONTH); 
    myDay = c.get(Calendar.DAY_OF_MONTH); 
    showDialog(ID_DATEPICKER); 
    } 
    }; 

@Override 
protected Dialog onCreateDialog(int id) 
{ 
    // TODO Auto-generated method stub 
    switch(id) 
    { 
    case ID_DATEPICKER: 
    Toast.makeText(Insert.this,"- onCreateDialog -",Toast.LENGTH_LONG).show(); 
    int myYear; 
    int myMonth; 
    int myDay; 
    return new DatePickerDialog(this,myDateSetListener,myYear, myMonth, myDay); 

    default: 
    return null; 
    } 
} 

private DatePickerDialog.OnDateSetListener myDateSetListener = new DatePickerDialog.OnDateSetListener() 
{ 
    @Override 
    public void onDateSet(DatePicker view, int year,int monthOfYear, int dayOfMonth) 
    { 
    // TODO Auto-generated method stub 
    String date = "Year: " + String.valueOf(year) + "\n"+ "Month: " + String.valueOf(monthOfYear+1) + "\n"+ "Day: " + String.valueOf(dayOfMonth); 
    Toast.makeText(Insert.this, date, 
     Toast.LENGTH_LONG).show(); 
    } 
}; 


findViewById(R.id.btnInsert).setOnClickListener(new OnClickListener() 
{ 
     public void onClick(View v) 
     { 

       DBAdapter dbAdapter = DBAdapter.getDBAdapterInstance(Insert.this); 
       dbAdapter.openDataBase(); 

       ContentValues initialValues = new ContentValues(); 
       initialValues.put("name", etName.getText().toString()); 
       initialValues.put("age", etAge.getText().toString());    
       long n = dbAdapter.insertRecordsInDB("user", null, initialValues);    
       Toast.makeText(Insert.this, "new row inserted with id = "+n, Toast.LENGTH_SHORT).show(); 

      } 
     }); 

} 

這是錯誤發生代碼日期選取了這個錯誤。 任何一個可以告訴我如何消除這個錯誤？

像這樣使用。

Button button=(Button) findViewById(R.id.btnInser); 
    button.setOnClickListener(new OnClickListener(){ 
    public void onClick(View v){ 

////your code goes here 
    } 
    });
