Android java.util.Calendar - Time Difference

Question

I want to make calendar view in order to support touch interaction. So I\'d like to build new custom calendar view. I tried to make mapping function between view offset and rea

This statement confuses me:

/* I expect mBaseDate == mAnotherDate.
 * but it was different.
 */

Are you actually trying to check for equality by doing the comparison: if (mBaseDate == mAnotherDate) { System.out.println("They are the same"); }

If so, your issue is that you are misunderstanding how the "==" operator works in Java. It compares references, rather than comparing the underlying object data, and since these are different objects (with the same values) that will always be false. For a lot more details, see the Java Notes on comparison operators.

Also, these lines look really suspicious to me:

/* We SHOULD call to update mDate internal data structure. 
* Java is really strange for this thing
**/
mDate.getTimeInMillis();

I would really be surprised if Android had a bug requiring you to do this, but I guess anything is possible. What kind of problems do you have without this call?
