BaseAdapter的ArrayIndexOutOfBoundsException

标签：

最近写一个listView中多个listItem布局时，convertView缓存及使用，类似微信的聊天界面的listView，报了一个异常：

102.         TextView mBodyView;  
103.         TextView mAddressView;  
104.         TextView mDateView;  
105.     }  

我的GlobalConstant.java中定义了type：

[java] view plaincopyprint?

 

1. public static final int TYPE_IN                         = 3;    // sms type: inbox  
2.       
3.     public static final int TYPE_OUT                        = 4;    // sim of other type  

琢磨了半天，我的getViewTypeCount()返回的是2，getItemViewType获取的是type值，同样是2个，为什么会报这个错误，在网上搜索到了一个关键信息：

从stackoverflow上看到的回答如下：

The item view type you are returning from getItemViewType() is >= getViewTypeCount().

确实是这个问题，我的type定义了2种，而且是从3开始。。。

讲GlobalConstant.java中的type值分别改为0,1,就解决了该问题：

[java] view plaincopyprint?

 

1. public static final int TYPE_IN                         = 0;    // sms type: inbox  
2.       
3.     public static final int TYPE_OUT                        = 1;    // sim of other type
