我的应用程序正在崩溃，得到显示java.lang.NullPointerException在CustomAdapter [英] My Application is being crashed and getting the java.lang.NullPointerException in CustomAdapter
问题描述
我有不同的选项卡（在tabhost）的应用程序，每个选项卡是扩展活动的活动，和一些富人文本字段和东西放在it.On我使用它我的第一个选项卡显示这是使用customadapter列表视图而这个名单正从服务器和数据数据正在更新list.App每次3秒后，工作正常，但有时它正在崩溃，并显示在某些点CustomAdapter显示java.lang.NullPointerException。
I have an application with various tabs (on a tabhost), each tab is an activity that extends activity, and haves some textfields and things on it.On my first tab i am using it for showing the listview which is using customadapter and this list is getting data from server and data is updating after each 3 seconds in list.App is working fine but sometime it is being crashed and showing java.lang.NullPointerException in CustomAdapter in some point.

推荐答案
似乎是有数据小于列表大小的ArrayList中的一个，看看哪些就行numbetr 719 ArrayList对象，你要访问，检查为什么ArrayList是不等于列表的大小。
Seems one of your arraylist is having data less then list size, See which arraylist object on the line numbetr 719, you are trying to access, and check why this arraylist is not equal to list size.
