BaseAdapter的ArrayIndexOutOfBoundsException
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：

代码如下：

- this.mContext = context;

- this.mDataList = dataList;
- }
- @Override

- return mDataList.size();
- }
- @Override
- public Object getItem(int position) {
- return mDataList.get(position);
- }
- @Override

- return position;
- }
- @Override

- return mDataList.get(position).getType();
- }
- @Override

- return 2;
- }
- @Override

- ViewHolderIn holderIn = null;
- ViewHolderOut holderOut = null;
- int type = getItemViewType(position);
- if(convertView == null)
- {
- switch(type){
- case GlobalConstant.TYPE_IN:

- break;
- }
- return convertView;
- }
- }
- private class ViewHolderIn {
- LinearLayout mFavSmsViewParent;
- TextView mBodyView;
- TextView mAddressView;
- TextView mDateView;
- }
- private class ViewHolderOut {
- LinearLayout mFavSmsViewParent;
- TextView mBodyView;
- TextView mAddressView;
- TextView mDateView;
- }
我的GlobalConstant.java中定义了type：
- public static final int TYPE_IN = 3; // sms type: inbox
- 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：
- public static final int TYPE_IN = 0; // sms type: inbox
- public static final int TYPE_OUT = 1; // sim of other type
