ANDROID listview BaseAdapter

最近寫一個listView中多個listItem布局時，convertView緩存及使用，類似微信的聊天界面的listView，報了一個異常：

我的GlobalConstant.java中定義了type：

[java]  view plain copy

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

琢磨了半天，我的getViewTypeCount()傳回的是2，getItemViewType擷取的是type值，同樣是2個，為什麼會報這個錯誤，在網上搜尋到了一個關鍵資訊：

從stackoverflow上看到的回答如下：

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

确實是這個問題，我的type定義了2種，而且是從3開始。。。

講GlobalConstant.java中的type值分别改為0,1,就解決了該問題：

[java]  view plain copy

BaseAdapter的ArrayIndexOutOfBoundsException
  1. public static final int TYPE_IN                         = 0;    // sms type: inbox  
  2.     public static final int TYPE_OUT    
BaseAdapter ArrayIndexOutOfBound
