我总是在收到一些消息之后得到ArrayIndexOutOfBoundsException，无论是从数据库接收还是从数据库加载。
它总是发生在同一个索引
java.lang.ArrayIndexOutOfBoundsException：length = 2;索引= 2
整个跟踪属于框架，我无法理解我哪里出错了。
片段的一部分：
@Override
public void chatCreated(Chat chat, boolean createdLocally) {
Log.v(TAG, ".chatCreated createdLocally:" + createdLocally);
chat.addMessageListener(new ChatMessageListener() {
@Override
public void processMessage(Chat chat, Message message) {
Log.v(TAG, "Message Received : " + message);
Log.v(TAG, "From:" + message.getFrom());
Log.v(TAG, "Type : " + message.getType());
Log.v(TAG, "Boody:" + message.getBody());
final Message msg = message;
Date date = new Date();
if (message.getBody() != null) {
final SqlMessage sqlMessage = new SqlMessage();
sqlMessage.body = message.getBody();
sqlMessage.time = new java.sql.Date(System.currentTimeMillis());
sqlMessage.type = SqlMessage.TYPE_RECEIVER;
MessagesDao.storeNew(mDatabase, sqlMessage);
Handler handler = new Handler(Looper.getMainLooper());
handler.post(() -> {
mChatMessageAdapter.add(sqlMessage);
Log.v(TAG, "msg inside handler : " + msg);
});
}
}
});
}
private class ChatMessageAdapter extends ArrayAdapter<SqlMessage> {
private LayoutInflater mInflater;
public ChatMessageAdapter(Context context) {
super(context, -1);
mInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
Log.d(TAG, "getview pos:" + position);
View view = convertView;
if (view == null) {
int resource;
switch (getItemViewType(position)) {
case SqlMessage.TYPE_SENDER:

答案 0 :(得分：6)
事实证明我的public int getItemViewType(int position)是罪魁祸首。我在其他地方更改了代码并返回了索引1和2，而不是0和1。
这可能是一个小错误，但不正确的错误报告使这成为一个主要问题。当getItemViewType(int position)返回的数字大于getViewTypeCount() - 1
感谢 TacticalJoke （#android-dev上的IRC缺口）修复此错误。
