我的代码中出现此错误。 请帮帮我。
我的代码如下。我不知道如何解决这个问题。当我点击添加按钮时，我想将所有数据添加到模型类中，并且该类应该填充主活动中的列表数组。

答案 0 :(得分：0)
我得到了它。 这里是获得完美result.in适配器的方法，只需将data.get（position）添加到countRecord方法。
public int CountRecord(ImageItemBin bin)
{
showImagelist.add(showBin);
int size=showImagelist.size();
tvcounter.setText(Integer.toString(size));
btnShow.setText(Integer.toString(size));
