Answer 1

您无法设置设备是 12 小时制还是 24 小时制，您也无法在 TextView 中进行设置。因此，您必须同时使用 format12Hour 和 format24Hour 属性以确保在这两种情况下，格式均为 hh:

<TextClock
            android:id="@+id/tvHourWidget"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:fontFamily="sans-serif-black"
            android:format12Hour="hh"
            android:format24Hour="hh"
            android:text="00"
            android:textColor="@color/colorPrimary"
            android:textSize="@dimen/basic_twice" />

您可以改用文本视图、计时器和简单的日期格式器，并设置所需的 DATETIME 格式

Timer tmm=new Timer();
public void start(TextView tv1){


    tmm.schedule(new TimerTask() {
        @Override
        public void run() {
            tv1.setText(""+ my_time("HH"));
        }
    },1000,1000);

}
public void Stop()
{
    tmm.cancel();
}


        public static String my_time(String format)
        {
            try{
                return new SimpleDateFormat(format).format(Calendar.getInstance().getTime());


            }catch (Exception ex){}
            return null;
        }
