this series aims to add varies app physical abilities with as little code lines inside the MainActivity. it is what the android studio IDEs should include as a default but they don't
so thank your lucky star I did it.

SoulTicker (java): this will run the code inside it's run method every tickMillies time
adding global variables to the class enables accessing them from within the tick.

Code:

public class SoulTickerTest implements Runnable{
    private Handler handler;
    private TextView textView;
    private PlayGround playGround =new PlayGround();
    private int tickMilis = 1000;
    public SoulTickerTest(Handler handler, TextView textView) {
        this.handler = handler;
        this.textView = textView;
    }

    public SoulTickerTest(Handler handler, TextView textView, int tickMilis) {
        this.handler = handler;
        this.textView = textView;
        this.tickMilis = tickMilis;

    }
public void turnOn(){handler.post(this);}
    public void setTickMilis(int tickMilis) {
        if(tickMilis<0){return;}
        this.tickMilis = tickMilis;
    }

    @Override
    public void run() {
        textView.setText(playGround.getCurrentTimeStamp());
        this.handler.postDelayed(this, tickMilis);
    }
}


here is the exact same class but in kotlin :

Code:

class SoulTickerTest:Runnable {
  private val handler:Handler
  private val textView:TextView
  private val playGround = PlayGround()
  private val tickMilis = 1000
  constructor(handler:Handler, textView:TextView) {
    this.handler = handler
    this.textView = textView
  }
  constructor(handler:Handler, textView:TextView, tickMilis:Int) {
    this.handler = handler
    this.textView = textView
    this.tickMilis = tickMilis
  }
  fun turnOn() {
    handler.post(this)
  }
  fun setTickMilis(tickMilis:Int) {
    if (tickMilis < 0) {
      return
    }
    this.tickMilis = tickMilis
  }
  public override fun run() {
    textView.setText(playGround.getCurrentTimeStamp())
    this.handler.postDelayed(this, tickMilis)
  }
}


here is how you use it from within the main class :

in the main class (kotlin):
val soulTickerTest = SoulTickerTest(Handler(),textView);
soulTickerTest.turnOn()

the textView var can be removed from the ticker, it's not a must.
the turnOn methode starts the ticking. the interval can be set as well using the
setTickMilis function.
