AspectJ in Android: pointcut call(* Activity.onCreate(..)) doesn't pick out Activity.onCreate() calls
Date : March 29 2020, 07:55 AM
it should still fix some issue Nice to see other people adventuring into aspectJ and Android :-) When using aspectJ with android you are limited to compile-time weaving, which basically means that you can only intercept code you own. public aspect LogAspect {
public String ATAG = "LogAspect";
pointcut tolog1() : execution(* Activity+.*(..)) ;
before() : tolog1() {
String method = thisJoinPoint.getSignature().toShortString();
Log.d(ATAG, "=========== entering " + method+", parms="+Arrays.toString(thisJoinPoint.getArgs()));
}
}

Android - Activity onCreate and Fragment onCreate
Date : November 23 2020, 12:01 PM
hope this fix your issue The fragment transaction commit command only puts the transaction in Que - the transaction will be processed some time in the future. This is why you couldnt use it straight from on create.
I suggest you to use fragments to encapsulate their Ui behavior - I wouldn't change a fragment's Ui elements explicitly from the activity.

Getting an error: onCreate(Bundle) in class clashes with onCreate(Bundle) in android.support.v4.app.Fragment
Date : March 29 2020, 07:55 AM
will be helpful for those in need I have made a class Navigation which extends Fragment. When I'm using onCreate() method it is giving me error saying onCreate() method of the class clashes with the onCreate() method of android.support.v4.app.Fragment. , Change: @Override
protected void onCreate(Bundle savedInstanceState) {
...
}
@Override
public void onCreate(Bundle savedInstanceState) {
...
}

Any of those help An optionmenu is literally just a menubutton and a menu, with a little bit of syntactic sugar. Here's a simple example showing how you can have submenus on something that looks just like an optionmenu: import tkinter as tk
root = tk.Tk()
var = tk.StringVar(value="one")
menubutton = tk.Menubutton(root, textvariable=var, indicatoron=True,
borderwidth=1, relief="raised", width=20)
main_menu = tk.Menu(menubutton, tearoff=False)
menubutton.configure(menu=main_menu)
for item in (("Numbers", "one", "two", "three"),
("Colors", "red", "green", "blue")
):
menu = tk.Menu(main_menu, tearoff=False)
main_menu.add_cascade(label=item[0], menu=menu)
for value in item[1:]:
menu.add_radiobutton(value=value, label=value, variable=var)
menubutton.pack(side="top", padx=20, pady=20)
root.mainloop()
