android - Auto refresh the activity

Question

In my application I have a activity that displays contents from internet..... I just want to know how can I auto refresh the activity.....

Please suggest and provide some code block if possible.

You can use handler to do a loop process, like this:

Handler handler = new Handler();
Runnable refresh;

In the first call time:

refresh = new Runnable() {
    public void run() {
        // Do something
        handler.postDelayed(refresh, 5000);
    }
};
handler.post(refresh);

Since you cannot call a non-final variable inside an annonymous class, you will have to declare refresh in the containing class.
