Question

I have developed a Bengali fixed layout softkeyboard for android and now want to add text prediction to it, how can i achieve this? Any pointer would be helpful, thanks in advance.

Answer 1

You have to write your own text prediction engine from scratch. Android does not provide one for you.

Here is a very brief overview:

1. Find a word frequency list on the web (many exist for English, not
   sure about Bengali)
2. Put it in an Sqlite database
3. Override InputMethodService.onKey() and get the string the user is currently typing
4. As the user types, query the Sqlite db for words that start with that string, sorted by frequency
5. Display the results in a View above the keyboard (check out the CandidateView class in the Softkeyboard sample in the Android SDK).

Good luck!
