I have created a Thread in onCreate(). It is running fine. Now I want to change something in view, when the thread is over. But if add it in the run() method, it is giving android.view.ViewRoot$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views. error. How to solve this problem?

Thread updateThread = new Thread() {
 @Override
 public void run() {
  ................
  ................
   //this line is giving problem
loader.setVisibility(View.INVISIBLE);                               
 }
};
updateThread.start();
