选择组
嗨，我创建了一个应用程序，将我的销售发票保存在sqlite中，再次显示你可以看到图片中的示例数据。
现在我想将数据添加到扩展列表适配器 HFO中的每一行都是列表视图中的一个组。 并且Hid = id的每个DFO都是HFO的子项。 我添加组数据，但当我想打开一个组我的应用程序崩溃
请帮助我的坦克。

我想要显示数据到消费列表，当我点击按钮我得到所有检查项目。
1 个答案:
答案 0 :(得分：0)
问题在于这个方法：
public int getChildrenCount(int groupPosition) {
return dFoStructs.get(groupPosition).size();
}
dFoStructs只有一个元素。
如果您尝试使用索引1获取值，则必须指向ArrayIndexOutOfBoundsException，因为Array从位置0开始。
如果groupPosition的计数从位置1开始，则必须注意减少索引，如下所示：
public int getChildrenCount(int groupPosition) {
return dFoStructs.get(groupPosition-1).size();
}
