Get Primary Key of Marker Clicked in Google Map in Android Development

Question

Help Needed. I have stored marker locations in an sqlite database in an android application in this way

1. Primary Key
2. Latitude
3. Longitude
4. Zoom

I want to compare all stored locations with my current location at regular intervals and want to delete any marked location whenever I want to remove and want to get primary key of clicked marker. Can anyone help me how to perform these operations by providing source code for this problem?

Answer 1

you can get you primary key by this query

var latitude,longitude; String query = "SELECT PrimaryKey FROM YourTable WHERE Latitude='"+latitude+"' AND Longitude='"+longitude+"';

then you can use this one to delete your pin from the map,
