I’m currently working on an android application that uses a subclass of SimpleListAdapter to bind a ListActivity. The list that the Adapter binds to is of type List<HashMap<String, Object>>.
I have to following If statement in the list Adapter…
if (dataRow.get("HasLineup1").toString()) == "0")
This never evaluates to true for me, even when the Eclipse debugger says that dataRow.get("HasLineup1").toString() is equal to "0" in the inspection window.
The list of data is populated from an XML source with the line
Game.put("HasLineup1", attributes.getNamedItem("home_lineup").getNodeValue());
I managed to work around the issue by changing the If statement to
if (Integer.parseInt(dataRow.get("HasLineup1").toString()) == 0)
Can someone explain to me why the first If statement I used wasn’t working? Java isn’t my native language, but I can’t for the life of me figure out what I’m doing wrong based on my .Net background.
The
==operator compares the instance memory location for non-primitive types therefore this fails unless the two sides of the operand are the same instance. Whenever dealing with non-primitive types, useequalsinstead of==.
