DataPicker以及TimePicker显示时间和日期（屏幕上显示），datepicker日期格式
public class MainActivity extends Activity {
private DatePicker date_picker;
private TimePicker time_picker;
private TextView tv_date;
private TextView tv_time;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//初始化
date_picker=(DatePicker) findViewById(R.id.date);
time_picker=(TimePicker) findViewById(R.id.time);
tv_date=(TextView) findViewById(R.id.tv_date);
tv_time=(TextView) findViewById(R.id.tv_time);
//获取当前的年月日时分信息
Calendar c=Calendar.getInstance();
int year = c.get(Calendar.YEAR);
int month=c.get(Calendar.MONTH);
int day=c.get(Calendar.DAY_OF_MONTH);
int hour=c.get(Calendar.HOUR_OF_DAY);
int minute=c.get(Calendar.MINUTE);
//使用Calendar显示时，月份从0开始，显示的时候加1
tv_date.setText("现在日期："+year+"-"+(month+1)+"-"+day);
tv_time.setText("现在时间："+hour+":"+minute);
//初始化日期时候，需要日期监听器
date_picker.init(year, month, day, new OnDateChangedListener() ;
//监听日期的改变
public void onDateChanged(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
// TODO Auto-generated method stub
//Toast.makeText(MainActivity.this, "现在时间："+year+"-"+(monthOfYear+1)+"-"+dayOfMonth, 0).show();
//月份以0开始统计，显示的时候要加1
tv_date.setText("现在日期："+year+"-"+(monthOfYear+1)+"-"+dayOfMonth);
}
});
//设置时间为24小时制
time_picker.setIs24HourView(true);
//时间监听器
time_picker.setOnTimeChangedListener(new OnTimeChangedListener() {
public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {
// TODO Auto-generated method stub
tv_time.setText("现在时间："+hourOfDay+":"+minute);
}
});
