Now this DEMO encapsulates it into a custom control and provides only three public interfaces:
1 public void switchClockState (_ ClockState state) // switch the clock status23 public void saveTimeToSystem () // Save the dial time to system time45 public void reviseTime () // The current recovery time is the system timeSo it is relatively convenient to look at the code in the main Activity, is it very simple:01 public class CustomClockDemoActivity exte
Android has its own clock UI component, AnalogClock and DigitalClock, respectively, for analog and digital clocks. 1.AnalogClock You can customize the dial, hour and minute hand. As follows, just set it in the XML file. - analogclock android:layout_width = "Wrap_content" android:layout_height= "Wrap_content" android:dial= "@drawable/ Watch " android:hand_
when the intent will start, it's entirely up to the user. So we need a pendingintent to pack the intent. Let's say I set an alarm in a.activity and want to open b.activity when the alarm goes off. I can make the following settings: Alarmmanager Alarmmanager = (Alarmmanager) Getsystemservice (alarm_service); New Intent (A.This, B.class); = Pendingintent.getactivity (A.ThisID , intent, 0); Alarmmanager.set (Alarmmanager.rtc_wakeup, Calendar.gettimeinmillis (), pendin
