I already used lucene in C# but I want to know if I could use it in java.
Yes there is also a library of Lucene in java and you can use it in android applications.
But there is a native full text search feature called FTS and and also new version FTS4 in SQLite , which you can use in android easily and it has a better performance and response time since its running natively and so much faster because uses less memory than java Lucene impelementation.
You can see a sample here : http://www.mysamplecode.com/2011/11/android-searchview-using-sqlite-fts3.html
and also full documentation here : http://www.sqlite.org/fts3.html
