Как показать Toast в классе, расширенном методом BaseAdapter Get View

У меня возникла проблема с отображением сообщения Toast, когда я нажимаю кнопку в списке View. Проблема в том, что пользовательский класс, расширенный BaseAdapter, у меня есть метод с именем GetView. Я хочу показать тост-сообщение из этого конкретного сообщения

Ниже приведен список Listview Row Xml

Заменить эту строку:

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

С этой строкой:

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

У вас есть контекст прямо в конструкторе. Создайте переменную уровня Контекстная переменная say ctx. Внутри конструктора писать

 this.ctx = context; 

Наконец, замените getApplication () в

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

С ctx.

Вы также можете использовать parent.getContext (), полный код тоста, как показано ниже

 Toast.makeText(parent.getContext(), "view clicked", Toast.LENGTH_SHORT).show();
