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

The answer by Pomber is acceptable, however I'm not a big fan of creating new objects repeatedly. The best solutions are always the ones that try to mitigate memory hog. Yes, there is auto garbage collection but memory conservation in a mobile device falls within the confines of best practice. The code below updates a TextView in a service.

TextViewUpdater textViewUpdater = new TextViewUpdater();
Handler textViewUpdaterHandler = new Handler(Looper.getMainLooper());
private class TextViewUpdater implements Runnable{
    private String txt;
    @Override
    public void run() {
        searchResultTextView.setText(txt);
    }
    public void setText(String txt){
        this.txt = txt;
    }

}

It can be used from anywhere like this:

textViewUpdater.setText("Hello");
        textViewUpdaterHandler.post(textViewUpdater);
