Android basics: running code in the UI thread

Question

In the viewpoint of running code in the UI thread, is there any difference between:

MainActivity.this.runOnUiThread(new Runnable() {
    public void run() {
         


        

Answer 1

I like the one from HPP comment, it can be used anywhere without any parameter:

new Handler(Looper.getMainLooper()).post(new Runnable() {
    @Override
    public void run() {
        Log.d("UI thread", "I am the UI thread");
    }
});
