First of all, I could not even chose the method to use, i'm reading for hours now and someone says use 'Handlers', someone says use 'Timer'. Here's what I try to achieve:
At preferences, theres a setting(checkbox) which to enable / disable the repeating job. As that checkbox is checked, the timer should start to work and the thread should be executed every x seconds. As checkbox is unchecked, timer should stop.
Here's my code:
Checking whether if checkbox is checked or not, if checked 'refreshAllServers' void will be executed which does the job with timer.
boolean CheckboxPreference = prefs.getBoolean("checkboxPref", true);
if(CheckboxPreference == true) {
Main main = new Main();
main.refreshAllServers("start");
} else {
Main main = new Main();
main.refreshAllServers("stop");
}
The refreshAllServers void that does the timer job:
public void refreshAllServers(String start) {
if(start == "start") {
// Start the timer which will repeatingly execute the thread
} else {
// stop the timer
}
And here's how I execute my thread: (Works well without timer)
Thread myThread = new MyThread(-5);
myThread.start();
What I tried?
I tried any example I could see from Google (handlers, timer) none of them worked, I managed to start the timer once but stoping it did not work. The simpliest & understandable code I saw in my research was this:
new java.util.Timer().schedule(
new java.util.TimerTask() {
@Override
public void run() {
// your code here
}
},
5000
);
Just simply use below snippet
private final Handler handler = new Handler();
private Runnable runnable = new Runnable() {
public void run() {
//
// Do the stuff
//
handler.postDelayed(this, 1000);
}
};
runnable.run();
To stop it use
handler.removeCallbacks(runnable);
Should do the trick.
