How to retrieve/read/get the location(lat & log) in sqlite database and show in the google map marker?

I have the sqlite database of 100 quantity shored in table:the colums are id,latitude,longitude and place condition.

My place condition are: Excellent, Good, Fair and Bad. If I text "Good" in my edittext box and press Button, it should show all the "Good" location in Google Map with marker and also all the 100 location.

How can I write a code for this to read all the location ,which is already stored in sqlite db.

I know this question may asked ,But i was not clear for beginners .
