Question

So I have the following thread:

  public class MyThread extends Thread
{
  Handler cHandler;
 private boolean looprunning = false;
  MyThread() {
  cHandler = new Handler();
          looprunning = true;

  }

  @Override
  public void run(){
      while (looprunning) {
          //do stuff here
        //update another system here or something else.
      }
  }

}

Inside the while loop of this thread, I want to run a Runnable that I pass to the thread while the thread is looping inside that while loop. How do I do this?

Answer 1

first please mark looprunning as volatile for proper thread visibility

you can use a queue

Queue<Runnable> taskQueue = new ConcurrentLinkedQueue<Runnable>();
@Override
public void run(){
   while (looprunning) {
       //do stuff here
     //update another system here or something else.
     Runnable r = taskQueue.poll();
     if(r!=null)r.run();
   }
} 

you can use a (thread-safe) queue of your choice
