[JAVA] Programming from 51 years old memorandum android Timer

Easy timer. The timer is a worker thread. But TimerTask has some unreliable behavior, so it seems to be Handler recommended. Also consider handler.postDelayed (runnable, delayMillis)!

The file to use is ・ Maina c Chity ty. See you Create an instance of Timer Create an instance of MyTimer Create ScheduleAtFixedRate method for Timer

・ My Chime r. See you Inherit TimerTask Create handle.post method of Handle and Runnable

MainActivity.java

public class MainActivity extends AppCompatActivity{

       @Override 
       protected void  onCreate(Bundle savedInstanceState){
                 super.onCreate(savedInstanceState);
                 setContentView(R.layout.activity_main);
       
                 Timer   timer   = new Timer();
                 MyTimer myTimer = new MyTimer(this);
                 timer.scheduleAtFixedRate(myTimer,0,10000);
       }
}

MyTimer.java

public class   MyTimer extends TimerTask{
       private Handler  handler;
       private Context context;
       private TIMER_STOP;

       public  MyTimer(Context context){
               handler       = new Handler();
               this.context  = context;
               TIMER_STOP    = false;
        }

       @Override 
       public void run(){
              handler.post(new Runnable(){
                   @Override 
                   public void run(){
                          Toast.makeText(context,"Toast",Toast.LENGTH_SHORT).show();
                   if(TIMER_STOP){
                      cancel();
                   }
                   }
              });
        }

        public void TimerStop(){
               TIMER_STOP = true;
        }
}

By calling myTimer.TimerStop () from MyActivity.class, cancel () </ font> </ strong> will be executed and the timer will stop. In the thread stop process, there is a process to stop the thread with @Override public void run () { while (KEY) {todo} </ font>}, but <font color = "#" When I did that in the execution part of f55 "> Timer, the while statement was executed indefinitely for each timer </ font>. So I used if () {cancel ()}!
