我正在尝试处理多个复选框,以便从列表中删除或编辑元素,列表中有自定义适配器及其自定义布局,在此布局中我创建了复选框,但是当我到达时,我得到一个IndexOutOfBounds异常尝试评估一个布尔数组,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:
适配器中的
public View getView
此
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,检查总是为0
有关此的任何提示吗?如果您需要更多信息,请告诉我

答案 0 :(得分:0)
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。
解决方案:
当数组询问自身的大小时,我决定使用ArrayList
创建变量来存储复选框:
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,现在我收到了我检查的对象!
