Answer 1

1. “==” compares reference values bit by bit not the value referenced by that reference.
2. “equals()” compares by value.Though equals method of base “Object” class is using “==” but it is overridden in most of class to compare value.

So Change into this :

if (extras!=null && s.equals("create_newfile")
    {
        setContentView(R.layout.edit);
    }
