我有以下活动运行不同的线程。我需要检索一个数组列表，但我得到的只是一个例外。我在谷歌上发现了类似的问题，但我无法使解决方案适应我的代码。ArrayList错误：java.lang.IndexOutOfBoundsException：无效索引26，大小为26
这里是我的类：

ArrayList<String> longitudeList;
// URL to get JSON

private static String url2 = "api";

super.onCreate(savedInstanceState);

代码中的哪一行是.MapActivity.updatePlaces（MapActivity.java:272）？ –
thelongtitude = longList.get（i）; – Xavier
