I remember around 10 years, I got so many problems on encoding when I read the chinese website. Whether it was simplified chinese(GB) or traditional chinese (BIG5). Sometimes, the website did not put the encoding setting in their HTML. So, a lot of times, I found the website was in non-readable. I needed to switch the encoding setting of my browser frequently.

For recently, most of webesites switched to Unicode, my problem is solved. According to Google, there are nearing 50% of website using Unicode now. That is good, I hope there will be 100% very soon. As a result, the encoding will be gone. Becuase Unicode is nearly including the characters from most of languages in the World.

I think the hottest IT@topic today is Apple iPad. Last night, Steve Jobs announced the first Apple's tablet PC, iPad, in his keynote. The rumors were talking about that for long long time.
It doesn't bring a lot of surpises to myself. It looks like an over-sized iPhone. Moreover, it has another key feature, iBook. iPad sounds a good eBook reader. But I am more prefer an eInk screen. iPad is using LED-backlight screen. I can't stand for reading a textbook on this kind of screen for long time! But the price is very very attractice. For 16GB version, that is only USD$499!

You can jump to a new window by changing the content view.

Code

But the type of Activity between two views must be same. In my case, I need to switch to a List view(Activity) from a normal window. I can't do by switching content views. The only way to do that is start a sub-activity, just like the following:

Code

Yes, then it will jump to a new window, after the action completes, my code will call "finish();" from the sub-activity. Then it will jump back to the main window.
