Wymień ten wiersz:

Toast.makeText(getApplication(), "Clicked Laugh Vote", Toast.LENGTH_SHORT).show();

z tej linii:

Toast.makeText(v.getContext(), "Clicked Laugh Vote", Toast.LENGTH_SHORT).show();

Masz rację kontekstu w konstruktorze. utwórz poziom klasy Zmienna kontekstowa powiedz ctx. wewnątrz konstruktora napisać

this.ctx = context;

wreszcie zastąpić getApplication() w

Toast.makeText(getApplication(), "Clicked Laugh Vote", Toast.LENGTH_SHORT).Show();

z CTX.
