Force близко при установке OnClick

Question

Я создал кнопку и назначил его 1, делая

remove.setId(0 + count); 

Затем я попытался поставить эту кнопку в моем OnCreate пачке использовать его

Button remove = (Button)findViewById(1); 

remove.setOnClickListener(new View.OnClickListener() { 

    @Override 
    public void onClick(View v) { 
     // TODO Auto-generated method stub 

    } 
}); 

Когда я создаю кнопка удаления в моем OnCreate он работает, но как только я добавить мой OnClick слушателя я не получаю никаких ошибок, но когда я запускаю его этом сила закрывает

Answer 1

Это ваша проблема: Кнопка удалить = (Button) findViewById (1);

Это должно быть что-то вроде этого:

Button remove = (Button)findViewById(R.id.buttonRemove); // that should be a long int 

Answer 2

Катастрофа, скорее всего, происходит от этой линии:

Button remove = (Button)findViewById(1); 

Вам необходимо предоставить действительное удостоверение личности для Button в вашем раздутом макете , Значение 1 не имеет смысла.
