当我在draweritemclicklistener上选择案例2并执行AsynTaskMain2（）时，它停止工作。请帮我解决这个问题:(

您的堆栈跟踪说明如下：
09-17 02:43:38.008: E/AndroidRuntime(14200): java.lang.IndexOutOfBoundsException: Invalid index 1, size is 1
09-17 02:43:38.008: E/AndroidRuntime(14200): at java.util.ArrayList.throwIndexOutOfBoundsException(ArrayList.java:251)
09-17 02:43:38.008: E/AndroidRuntime(14200): at java.util.ArrayList.get(ArrayList.java:304)
09-17 02:43:38.008: E/AndroidRuntime(14200): at com.slowbrocorp.aplikasiargpsdangistempattransportasiumum.BandaraMap.onInfoWindowClick(BandaraMap.java:571)
这意味着：对ArrayList.get（）的调用是从MandaraMap.onInfoWindowClick（）第571行开始的，参数为1，这是不合法的，因为ArrayList中只有一个元素。
第571行是哪一行？我在您发布的代码中看不到get()中onInfoWindowClick()的任何调用，这让我觉得您发布的代码不是您正在运行的代码。
