Android threads and handler not working

Question

I recently reorganized an old project and found that a certain part no longer wants to work properly no matter what I do. Essentially, I have an Activity with a TextView. This view is updated at regular intervals from a thread called in the same class. A pause is performed using Thread.sleep, and a handler is used to start updating the user interface. The fact is that now I either get a CalledFromWrongThreadException, saying that I can not manipulate the view from another thread, a long pause, followed by all the text that got into the view right away, or it seems to fire immediately and do not sleep at all. I previously did it like this (relevant parts were included):

public class Updated extends Activity implements Runnable {

private TextView textView;
private String text;
private Handler handle = new Handler(){
    @Override
    public void handleMessage(Message msg){
        textView.append(text);
    }
};
//onCreate and other such things...{
    new Thread(this).start();
}

public void run(){
     //A healthy chunk of logic/conditionals
     text = "Blah blah";
     handle.sendEmtpyMessage(0);
     try {
    Thread.sleep(1500l);
 } catch (InterruptedException e) {
    e.printStackTrace();
 }
}
