Read Sqlite database and display in Google Map?

My app has one database table with 100 rows stored in Sqlite, which has the following columns:

id (primary key) category Latitude Longitude

My category consists of "Excellent", "Good", "Fair" and "Poor". Example: My Excellent contains 35 rows and I want to show all the 35 values(latitude & longtiude) in Google Map. This I want to do by EditText box adding typing excellent in editBox and press button.It should show all the 35 values in Map. Similar for Good, Fair and Poor.
