Hallo, ich bin neu hier und bräuchte mal eure Hilfe..
und zwar gehts um Radiobuttons in einemTableLayout was über eine Klasse gesteuert wird. Den Klassencode hab ich im Netz gefunden und funktionert auch soweit ganz gut.
Das einziege was ich nicht hinbekomme ist ein onClick Event auf die Buttons.. weder mit "android:onClick" per xml oder per "OnClickListener" in der Activity..
Wenn ich aber einen RadioButton gezielt ansteurere per code, funktioniert zwar das onclick event, aber dafür nicht mehr das checked event.. 
thx für die hilfe schon mal..
