Android expandableListView中getChildView（）处的IndexOutofBoundException
我正在添加三个子对象，其名称为“所有住宅”“所有地块”和“所有商业”，我在运行时添加这三个对象，其父对象为“住宅”“地块”和“商业”，因此，换句话说，我在我的父对象中添加了三个其他类别作为子对象。我在加载expandableListview时会加载子对象数组的索引为0，但每当我尝试单击这些新创建的对象时，就会在方法getChildView（）处出现indexoutofboundexception错误由于IndexOutOfBoundException invalid index 7 size为7，当我单击填充子数据时，调试器显示此错误，当我返回时，调试器在此方法中显示此IndexOutOfBoundException错误。 我修改的代码是Android expandableListView中getChildView（）处的IndexOutofBoundException,android,indexing,arraylist,expandablelistview,indexoutofboundsexception,Android,Indexing,Arraylist,Expandablelistview,Indexoutofboundsexception,我正在添加三个子对象，其名称为“所有住宅”“所有地块”和“所有商业”，我在运行时添加这三个对象，其父对象为“住宅”“地块”和“商业”，因此，换句话说，我在我的父对象中添加了三个其他类别作为子对象。我在加载expandableListview时会加载子对象数组的索引为0，但每当我尝试单击这些新创建的对象时，就会在方法getChildView（）处出现indexoutofboundexception错误由于IndexOutOfBoundException invalid index 7 size为7

请更改您的循环大小 你必须像这样循环条件 对于（int i=0；i
大小-1旁注：parent.getTypeId（）=“9,8,21,22,20,24,25”。将==替换为.equals。还有，你为什么要把父母添加到你的孩子列表中？@carnal我工作的地方他们已经在根据网络服务从url获取数据，但现在他们想硬编码这三个类别——所有家庭，所有地块，所有商业化，因此，在所有家庭中，所有家庭的孩子来了，在所有绘图中，孩子来了，在将来，如果他们想添加另一个功能，他们可以硬编码以获得结果，而不改变API。同样是java.lang.IndexOutOfBoundsException:索引7无效，片段大小为7。类型$ExpandableAdapter.getChildView（Types.java:254）如果我将其设为Utils.propertyTypesList.size（）-1则数组将无法正常遍历，就像它将遍历0和1索引一样，并将离开2索引，因此仅显示所有家庭所有绘图，但错误仍然存在，即在单击单选按钮填充数据后，i come bak indexoofbound异常错误出现，应用程序崩溃
