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：

class FavoriteSmsListAdapter extends BaseAdapter {private Context mContext;private LayoutInflater mInflater;private ArrayList<FavoriteSmsModel> mDataList;public FavoriteSmsListAdapter(Context context) {super();this.mContext = context;this.mInflater = LayoutInflater.from(context);}private void setUpData(ArrayList<FavoriteSmsModel> dataList) {this.mDataList = dataList;}@Overridepublic int getCount() {return mDataList.size();}@Overridepublic Object getItem(int position) {return mDataList.get(position);}@Overridepublic long getItemId(int position) {return position;}@Overridepublic int getItemViewType(int position) {return mDataList.get(position).getType();}@Overridepublic int getViewTypeCount() {return 2;}@Overridepublic View getView(final int position, View convertView, ViewGroup parent) {ViewHolderIn holderIn = null;ViewHolderOut holderOut = null;int type = getItemViewType(position);if(convertView == null){switch(type){case GlobalConstant.TYPE_IN:convertView = mInflater.inflate(R.layout.favorite_sms_list_item_recv, parent, false);holderIn = new ViewHolderIn();holderIn.mFavSmsViewParent = (LinearLayout) convertView.findViewById(R.id.fav_sms_view_parent);holderIn.mBodyView = (TextView) convertView.findViewById(R.id.body_view);holderIn.mAddressView = (TextView) convertView.findViewById(R.id.address_view);holderIn.mDateView = (TextView) convertView.findViewById(R.id.date_view);convertView.setTag(holderIn);break;case GlobalConstant.TYPE_OUT:convertView = mInflater.inflate(R.layout.favorite_sms_list_item_send, parent, false);holderOut = new ViewHolderOut();holderOut.mFavSmsViewParent = (LinearLayout) convertView.findViewById(R.id.fav_sms_view_parent);holderOut.mBodyView = (TextView) convertView.findViewById(R.id.body_view);holderOut.mAddressView = (TextView) convertView.findViewById(R.id.address_view);holderOut.mDateView = (TextView) convertView.findViewById(R.id.date_view);convertView.setTag(holderOut);break;}}else{switch(type){case GlobalConstant.TYPE_IN:holderIn = (ViewHolderIn)convertView.getTag();break;case GlobalConstant.TYPE_OUT:holderOut = (ViewHolderOut)convertView.getTag();break;}}FavoriteSmsListItem listItem = (FavoriteSmsListItem) convertView;switch(type){case GlobalConstant.TYPE_IN:listItem.bind(mContext, mDataList.get(position), holderIn.mFavSmsViewParent, holderIn.mBodyView, holderIn.mAddressView, holderIn.mDateView);break;case GlobalConstant.TYPE_OUT:listItem.bind(mContext, mDataList.get(position), holderOut.mFavSmsViewParent, holderOut.mBodyView, holderOut.mAddressView, holderOut.mDateView);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: inboxpublic 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: inboxpublic static final int TYPE_OUT = 1;// sim of other type
