This does not work, like this, as onClick() is run on the UI thread, blocking it for updates until your onClick() returns. While

You can solve that with an AsyncTask, where the doInBackground() method is doing the loop, sending the number to print via publishProgress() and have onProgressUpdate() update the TextView.

Here is an example of the usage of AsyncTask. Also have a look at the docs which also illustrates progress updates.

There is a function is textview called append. You can this function for the purpose:

On how to use this function:

name.append("\n" + i);

For printing them after an interval, you can Handler and runnable combo OR asynctask.
