Possible duplicate:How to support Arabic text on Android?
how to use arabic text and how to get arabic language support in android.unicode.
TextView tv=(TextView)findViewByid(R.id.text);
use the font for the text box and use the Arabic ttf for this. tv.setTypeFace is an API
I assume this is firmware, I use the latest CyanogenMod 7.1 on my Nexus S, and I have Arabic for menu input and text input.
After that you can use the font.
