Date/TimePickerDialog只是供用户来选择日期时间,对于android系统的系统时间, 日期没有任何影响

他们两个的构造方法非常相似： DatePickerDialog(上下文；DatePickerDialog.OnDateSetListener()监听器；年；月；日)
TimePickerDialog(上下文；TimePickerDialog.OnTimeSetListener()监听器；小时，分钟，是否采用24小时制)

public 
class MainActivity extends
AppCompatActivity implements
View.OnClickListener{
  private
Button btn_date;
  private
Button btn_time;
  private
String result = "";
  @Override
  protected
void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    bindViews();
  }
  private
void bindViews() {
    btn_date = (Button) findViewById(R.id.btn_date);
    btn_time = (Button) findViewById(R.id.btn_time);
    btn_date.setOnClickListener(this);
    btn_time.setOnClickListener(this);
  }
  @Override
  public
void onClick(View v) {
    result =
"";
    switch
(v.getId()){
      case
R.id.btn_date:
        Calendar cale1 = Calendar.getInstance();
        new
DatePickerDialog(MainActivity.this,new
DatePickerDialog.OnDateSetListener() {
          @Override
          public
void onDateSet(DatePicker view,
int year, 
int monthOfYear,
                     int
dayOfMonth) {
            //这里获取到的月份需要加上1哦~
            result +=
"你选择的是"+year+"年"+(monthOfYear+1)+"月"+dayOfMonth+"日";
            Toast.makeText(getApplicationContext(), result, Toast.LENGTH_SHORT).show();
          }
        }
            ,cale1.get(Calendar.YEAR)
            ,cale1.get(Calendar.MONTH)
            ,cale1.get(Calendar.DAY_OF_MONTH)).show();
        break;
      case
R.id.btn_time:
        Calendar cale2 = Calendar.getInstance();
        new
TimePickerDialog(MainActivity.this,
new TimePickerDialog.OnTimeSetListener() {
          @Override
          public
void onTimeSet(TimePicker view,
int hourOfDay, 
int minute) {
            result =
"";
            result +=
"您选择的时间是:"+hourOfDay+"时"+minute+"分";
            Toast.makeText(getApplicationContext(), result, Toast.LENGTH_SHORT).show();
          }
        }, cale2.get(Calendar.HOUR_OF_DAY), cale2.get(Calendar.MINUTE),
true).show();
        break;
    }
  }
}
