Question

I am storing a double into a sqlite database.
This value can be null, and I need to know whether the value is 0 or null.

Is it possible to achieve this?

//grade is a type double in database
Double myValue =  cursor.getDouble(cursor.getColumnIndex("grade"));

Answer 1

To check for null use ‘isNull(…)’…

Double myValue;
if (!cursor.isNull(cursor.getColumnIndex("grade"))
    myValue =  cursor.getDouble(cursor.getColumnIndex("grade"));
else
    // Handle null scenario
