If we want to update UI from a Non-UI thread then runOnUiThread() is the best solution for it.

I am showing Toast in every 25 secs. Below is the code

   
private Thread refreshThread;
  refreshThread = new Thread() {

     @Override
        public void run() {
            try {
                while (!isInterrupted()) {
                    Thread.sleep(25000);
                    runOnUiThread(new Runnable() {
                        @Override
                        public void run() {
                            Toast.makeText(DriversHomeActivity.this, "Thread", Toast.LENGTH_SHORT).show();

                        }
                    });
                }
            } catch (InterruptedException e) {
            }
        }
    };

    refreshThread.start();

When we want to stop an this, just call interrupt() method.

   refreshThread.interrupt();
