    import android.view.Menu;
    import android.widget.DatePicker;
    import android.widget.DatePicker.OnDateChangedListener;
    import android.widget.TimePicker;
    import android.widget.TimePicker.OnTimeChangedListener;
    import android.widget.Toast;
    
    public class MainActivity extends Activity {
    
    	@Override
    	protected void onCreate(Bundle savedInstanceState) {
    		super.onCreate(savedInstanceState);
    		setContentView(R.layout.activity_main);
    		DatePicker datePicker = (DatePicker) findViewById(R.id.datePicker1);
    		Calendar calendar = Calendar.getInstance();
    		int year = calendar.get(Calendar.YEAR);
    		int month = calendar.get(Calendar.MONTH);
    		int day = calendar.get(Calendar.DAY_OF_MONTH);
    		datePicker.init(year, month, day, new OnDateChangedListener() {
    
    			@Override
    			public void onDateChanged(DatePicker view, int year,
    					int monthOfYear, int dayOfMonth) {
    				// TODO Auto-generated method stub
    				Toast.makeText(
    						MainActivity.this,
    						"您选择的日期是：" + year + "年" + (monthOfYear + 1) + "月"
    								+ dayOfMonth + "日!", Toast.LENGTH_LONG).show();
    			}
    		});
    
    		TimePicker timePicker = (TimePicker) findViewById(R.id.timePicker1);
    		timePicker.setIs24HourView(true) ;//解决屏幕显示时间是24小时制，还是12小时制
    		timePicker.setOnTimeChangedListener(new OnTimeChangedListener() {
    
    			@Override
    			public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {
    				// TODO Auto-generated method stub
    				Toast.makeText(MainActivity.this,
    						"您选择的时间是：" + hourOfDay + "时" + minute + "分!",
    						Toast.LENGTH_LONG).show();
    			}
    		});
    	}
