How to use zoom controls on TextView in Android?

I want to zoom text that is displayed at center of screen as per user choice. How can I achieve this ?
Using pinch multitouch cannot be tested on emulator and I want something that I can test on Android emulator.
Can I use zoom in and out controls to control only text view for my layout ?
Or Can I use webview to contain a text as webview has default zoom in out buttons ?

There is no built-in support for that. You can probably achieve this effect yourself by drawing the text using the 2D graphics APIs (Canvas) and touch events. Or, intercept touch events on a TextView and change the font size of the text.
