Question

I have the following function call from a thread:

        Thread Move = new Thread(){
            public void run()
            {
                while(ButtonDown){
                    UpdateValues();
                    try {
                        Thread.sleep(50);
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                }
            }
        };
        Move.start();

Will Android delete the thread when the while-loop breaks, or do I have to delete it in some way?

Answer 1

When you return from the thread, you have essentially stopped it, so no, you don’t need to do anything specific to delete the thread. Please keep in mind that this is not a good use case for threads in Android. If you are updating the UI from a non-UI thread you will most likely get the framework complaining at you. Instead, you should read a few tutorials on AsyncTask and move to that model, as it will let you update the UI.
