如何在Android应用程序中显示当前日期和时间?
当前回答
Use:
Calendar c = Calendar.getInstance();
int seconds = c.get(Calendar.SECOND);
int minutes = c.get(Calendar.MINUTE);
int hour = c.get(Calendar.HOUR);
String time = hour + ":" + minutes + ":" + seconds;
int day = c.get(Calendar.DAY_OF_MONTH);
int month = c.get(Calendar.MONTH);
int year = c.get(Calendar.YEAR);
String date = day + "/" + month + "/" + year;
// Assuming that you need date and time in a separate
// textview named txt_date and txt_time.
txt_date.setText(date);
txt_time.setText(time);

如果您想以特定的模式获取日期和时间,可以使用
Date d = new Date();
CharSequence s = DateFormat.format("yyyy-MM-dd hh:mm:ss", d.getTime());
String formattedDate = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(Calendar.getInstance().getTime());
使用formattedDate作为填充日期的字符串。 在我的情况下:mDateButton.setText(formattedDate);
为显示当前日期和时间的Textview
/// For Show Date
String currentDateString = DateFormat.getDateInstance().format(new Date());
// textView is the TextView view that should display it
textViewdate.setText(currentDateString);
/// For Show Time
String currentTimeString = DateFormat.getTimeInstance().format(new Date());
// textView is the TextView view that should display it
textViewtime.setText(currentTimeString);
检查完整的代码Android -显示当前日期和时间在一个Android Studio示例的源代码
我自己的工作解决方案:
Calendar c = Calendar.getInstance();
String sDate = c.get(Calendar.YEAR) + "-"
+ c.get(Calendar.MONTH)
+ "-" + c.get(Calendar.DAY_OF_MONTH)
+ " at " + c.get(Calendar.HOUR_OF_DAY)
+ ":" + c.get(Calendar.MINUTE);
希望这能有所帮助!
Use:
Calendar c = Calendar.getInstance();
int seconds = c.get(Calendar.SECOND);
int minutes = c.get(Calendar.MINUTE);
int hour = c.get(Calendar.HOUR);
String time = hour + ":" + minutes + ":" + seconds;
int day = c.get(Calendar.DAY_OF_MONTH);
int month = c.get(Calendar.MONTH);
int year = c.get(Calendar.YEAR);
String date = day + "/" + month + "/" + year;
// Assuming that you need date and time in a separate
// textview named txt_date and txt_time.
txt_date.setText(date);
txt_time.setText(time);
