datePicker 及 timePicker 监听事件 获取用户选择 年月日分秒信息

public class MainActivity extends AppCompatActivity {
private TimePicker timePicker;
private DatePicker datePicker;
private Calendar cal; private int year;
private int month;
private int day;
private int hour;
private int minute; @Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//注册 对象
timePicker = (TimePicker)findViewById(R.id.timePicker);
datePicker = (DatePicker)findViewById(R.id.datePicker); //获取年月日分秒信息
cal = Calendar.getInstance();
year = cal.get(Calendar.YEAR);
month = cal.get(Calendar.MONTH);
day = cal.get(Calendar.DAY_OF_MONTH) + 1 ; //月份从0开始的 所以要加1
hour = cal.get(Calendar.HOUR_OF_DAY);
minute = cal.get(Calendar.MINUTE); //标题显示
setTitle(year + "-" + month
+"-"+ day + "-" + hour + ":" + minute ); //datePicker初始化 设置初始日期
datePicker.init(year, cal.get(Calendar.MONTH), day, new DatePicker.OnDateChangedListener() {
@Override
public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
setTitle(year + "-" + (monthOfYear + 1 )
+"-"+ dayOfMonth );
}
});
}

  TimePicker 监听事件 例子

        timePicker.setOnTimeChangedListener(new TimePicker.OnTimeChangedListener() {
@Override
public void onTimeChanged(TimePicker view, int hourOfDay, int minute) { setTitle(hourOfDay + ":" + minute);
}
});

 同时监听日期 时间 可以做闹钟

public class MainActivity extends AppCompatActivity {
private TimePicker timePicker;
private DatePicker datePicker;
private Calendar cal; private int Year;
private int month;
private int day;
private int hour;
private int Minute; @Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//注册 对象
timePicker = (TimePicker)findViewById(R.id.timePicker);
datePicker = (DatePicker)findViewById(R.id.datePicker); //获取年月日分秒信息
cal = Calendar.getInstance();
Year = cal.get(Calendar.YEAR);
month = cal.get(Calendar.MONTH) + 1 ; //月份从0开始的 所以要加1
day = cal.get(Calendar.DAY_OF_MONTH) ;
hour = cal.get(Calendar.HOUR_OF_DAY);
Minute = cal.get(Calendar.MINUTE); //标题显示
setTitle(Year + "-" + month
+"-"+ day + "-" + hour + ":" + Minute ); //datePicker初始化 设置初始日期
datePicker.init(Year, cal.get(Calendar.MONTH), day, new DatePicker.OnDateChangedListener() {
@Override
public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
month = monthOfYear + 1;
day = dayOfMonth;
Year = year;
setTitle(Year + "-" + month
+"-"+ day + "-" + hour + ":" + Minute );
}
}); timePicker.setOnTimeChangedListener(new TimePicker.OnTimeChangedListener() {
@Override
public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {
hour = hourOfDay;
Minute = minute;
setTitle(Year + "-" + month
+"-"+ day + "-" + hour + ":" + Minute ); }
});
}
