Call to getLayoutInflater() in places not in activity
...
@RohanBhatia Davides answer does not require casting which mine does. If the call to getSystemService for some (unlikely) reason does not return an object of type LayoutInflater then my code would cause a runtime exception.

Java 8 Lambda function that throws exception?
... new Exception("asdas");
};
list.forEach(throwingConsumer);

// maybe some other code here...
throw new Exception("asda");
});
Update: Looks like there's a very nice utility library part ...
The performance impact of using instanceof in Java
...
If "object" is an instance of ObjT, casting it is a little faster than doing an instanceof, but the difference my quick test found was 10-20ms over 10,000,000 iterations. If "object" isn't an ObjT, though, catching the exception was over 3000x slower - over 31,...

return (Bar)foo;
}
Instead of:
var bar = foo as Bar;
if(bar != null) {
return bar;
}

How do you get the logical xor of two variables in Python?
...!= bool(b) != bool(c) to be the same as bool(a) ^ bool(b) ^ bool(c). So do casts to bool, but I would recommend ^. To know what's going up in the first example look up "operator chaining".
