标签： android list arraylist indexoutofboundsexception

在我的应用程序中，我想从服务器获取一些列表，并将此列表显示为 ChipCloud 。 ChipCloud有标记库。 图书馆链接： https://github.com/adroitandroid/ChipCloud
。我写下面的代码但是当点击项目时运行应用程序会显示在错误：

        }
    });
}

显示此行的错误： 

chipKey = cloudChipList.get(i);

如何修复此错误？请帮帮我我的朋友。我真的需要你的帮助。请

2 个答案:

答案 0 :(得分：0)

在错误中说，

cloudChipList

这意味着searchResponse.getData().getMostlyMatchedKeywordsText();中的实际元素数仅为6.也就是说，public void chipSelected(int i)函数只返回6个值，然后存储在数组列表中。但是，当您调用i函数时，如果java.lang.IndexOutOfBoundsException的值大于5，则会显示此i。如果您的数组列表中有6个值，那么您只能提供从0到5的索引值。在您的情况下，public void chipSelected(int i)中{{1}}的值为11，因此错误。

答案 1 :(得分：0)

schipSelected方法的索引正在ChipCloud类中计算。 

fullSearchMini_chipCloud.setChipListener(new ChipListener() {
            @Override
            public void chipSelected(int i) {  //This is callback from ChipCloud class
                chipKey = cloudChipList.get(i);
            }

            @Override
            public void chipDeselected(int i) {

            }
        });

fullSearchMini_chipCloud布局正在添加重复筹码。在添加新筹码之前，您需要清除现有的孩子。

用

清除列表后 
cloudChipList.clear();

使用

删除现有的子项 
fullSearchMini_chipCloud.removeAllViews()
