从列表中删除项目-投射

Question

In my List I'd like to remove an item: v is the button I clicked on. I tagged the position with holder.button1.setTag(position);

Then, in the GetView's ClickListener :

Log.e("Tag", String.valueOf((Integer) v.getTag()));  //returns 2
data.remove((Integer) v.getTag()); //Does not remove the item
data.remove(2); //Removes it !!!!

Where is my error ?

EDIT : Where

holder = new NewsHolder();

and

static class NewsHolder{

    TextView itemName;
    ImageView icon;
    Button button1;
    Button button2;
    Button button3;


}

Answer 1

您是否尝试过使用int类型而不是Integer，后者是不同于int类型的对象？
