hi all,

i m new to android and i will like to know if there is any function provided for refreshing a page <view>or any other utility? say i have text view on my page and the text is continuously updating then i need to show the updated page with updated text.


thanks in advance,
Prashant

I don't really understand you. If you are talking about a webpage, you can reload it using javascript. If you are talking about a TextView, then it's automatically updated. If you are talking about some custom view, you probably have to call View.invalidate().

hi Mr.Sf,
thanks for ur kind information.
what i want to say is if my page is displaying some text which is being fetched from external resource , like cricket match score, being updated after every 1 minute , then how can i refresh my page for new display?

Have an update method fetch the new data from the source and update the textview.

Use a Handler to delay the update Runnable.
And have the Runnable postDelay itself on the handler.
In your onCreate (where this.handler is a private Handler hander):

and a somewhere else in the class:


Why use Handler? Because Handler allows you to do threading stuff inside the main thread, which allows for less memory usage and probably lower battery usage.
