xml - Android - Text wraps in designer and emulator but not on device -


beginner android developer. i'm using eclipse write , design app.

suddenly, textviews have stopped wrapping text on physical android device. alert dialogs no longer wrap well. wrapping works correctly in designer , in emulator.

they wrapped correctly on device last time tested it. since doing so, i've added new activity few buttons on it. don't believe changed on main menu activity, below:

php - Accessing static methods using newly created $obj or using class Name -

see class definition below: i using 5.3.9 version of php class a{ static function ab(){ echo "static function ab<br>"; } public function xy(){ echo "public function xy<br>"; } } $obj = new a(); $obj->ab(); a::ab(); both functions call give same output without error static function ab static function ab how possible static method can called class object? because static method calls using class name only?! now difference between accessing these 2 ways call static method ? referring php.net website declaring class properties or methods static makes them accessible without needing instantiation of class. property declared static can not accessed instantiated class object (though static method can). a big difference is because static methods callable without instance of object created, pseudo-variable $this not available inside method declared static. refer page php.net/manual/en/
