activity示例代码:

public class DatePickerDIalogDemoActivity extends Activity {

    private Button btn1=null;

    private TextView tv1=null;

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

        btn1=(Button)findViewById(R.id.btn);

        btn1.setOnClickListener(new Btn());

        tv1=(TextView)findViewById(R.id.tv1);

    }

    //创建监听器

    @Override

   protected Dialog onCreateDialog(int id) {

      // TODO Auto-generated method stub

      switch(id){

      case 1:{

         return new DatePickerDialog(this,dateP,2011,8,15);

      }

      }

      return null;

   }

    //按钮监听器

   class Btn implements OnClickListener{

 

      public void onClick(View v) {

        // TODO Auto-generated method stub

        showDialog(1);

      }

      

    }

 

    //创建监听器类

    DatePickerDialog.OnDateSetListener dateP=new DatePickerDialog.OnDateSetListener() {

      

      public void onDateSet(DatePicker view, int year, int monthOfYear,

           int dayOfMonth) {

         tv1.setText(year+"-"+(monthOfYear+1)+"-"+dayOfMonth);

      }

   };

}
