android - 如何通过按钮自动获取日期

Question

我想知道如何通过 Android Studio 中的 Android 应用程序通过按钮自动检索日期。

Answer 1

在您的 onClick 按钮侦听器方法中添加：

Time today = new Time(Time.getCurrentTimezone());
today.setToNow();

Answer 2

也许这可以帮助你：

   yourButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                //Create Date Object
                Date today = new Date();

                //Convert to calendar Object
                Calendar calendar = Calendar.getInstance();
                calendar.setTime(today);

                int year = calendar.get(Calendar.YEAR);
                int month = calendar.get(Calendar.MONTH);
                int dayOfMonth = calendar.get(Calendar.DAY_OF_MONTH);
                int dayOfWeek = calendar.get(Calendar.DAY_OF_WEEK);
                int weekOfYear = calendar.get(Calendar.WEEK_OF_YEAR);
                int weekOfMonth = calendar.get(Calendar.WEEK_OF_MONTH);
              }
        });
