Question

I am running multiple thread and Handler in my code.

And this is my Handler

PrizeRunnable mTempPotionRunnable = new PrizeRunnable(aaa);
handler.postDelayed(mTempPotionRunnable, 4000);

and

        class PrizeRunnable implements Runnable {
        String type;

        PrizeRunnable(String type) { 
            this.type = type; 
        }

        public void run() {
            synchronized (this) {
                  if(!mIsHandlerStarted){
                      if(type.equals(aaa))
                          // Do something
                      else if(type.equals(bbb))
                          // Do something

                    mIsHandlerStarted = true;
                    handler.removeCallbacks(this);
                  }
              }
        }
    }

But sometime it run simultaneously.

i don not know the reason.

UPDATED

I try to change it to:

handler.postDelayed(mTempPotionRunnable, 4000);

and

Runnable mTempPotionRunnable = new Runnable() {
@Override
public void run() {
      synchronized (this) {
          if(!mIsHandlerStarted){
                // Do something
                mIsHandlerStarted = true;
                handler.removeCallbacks(mMetalRunnable);
          }
      }
}
};

May be it resolve my problems. I am testing this method.

But i can’t pass parameter to my Runnable . How can i do it?
