带有listview的自定义适配器中的多个复选框，indexOutOfBounds

Question

我试图处理多个复选框，以便从列表中删除或编辑元素，列表具有自定义适配器及其自定义布局，在此布局中我创建复选框，但是当我尝试评估时，我得到一个IndexOutOfBounds异常一个布尔数组，即使它已被初始化。

public MeasureTableAdapter(Activity context, ArrayList<MeasureEvi> myMeasureEvi) 
{
    super(context, R.layout.adapter_tablamedida_item, myMeasureEvi);
    this.context = context;
    this.myMeasureEvi = myMeasureEvi;
    checked= new boolean[myMeasureEvi.size()]; //this is where I initialize the array
}

这是我在以下地方获得例外的地方：

在适配器中

 public View getView

这个

if (checked[position]) {
        holder.checkBox.setChecked(true);
    } else {
        holder.checkBox.setChecked(false);
    }

登录调试窗口

checked[position]= java.lang.IndexOutOfBoundsException : Invalid array range: 0 to 0

我放了一个断点，我可以看到myMeasureEvi的大小不是0，但由于某种原因，检查总是0

有什么暗示吗？ 如果您需要更多信息，请告诉我

通过在我的应用程序上进行更深入的调试，我注意到适配器正在以前的方式进行初始化，因此它不再用于构造函数，除非再次初始化，因此数组的大小将始终为0。

解：

当数组询问自身的大小时，我决定使用ArrayList

创建变量来存储选中的框：

public static ArrayList<MeasureEvi> myChecked = new ArrayList<MeasureEvi>();

创建一个监听器事件来存储您的选择：

holder.checkBox.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            if(holder.checkBox.isChecked()) {
                myChecked.add(DataIpat.measureEviArray.get(position));
            }
            else {
                myChecked.remove(DataIpat.measureEviArray.get(position));
            }
            for (int i=0; i<myChecked.size(); i++){
                MeasureEvi e= myChecked.get(i);
                Log.d("mOrder", String.valueOf(e.getmOrderIndex()));
            }
        }
    });

和KABOOM，现在我有我检查的对象！
