XML文件：

BaseTable.xml:

<?xml version="1.0"?> 
<tables> 
  <table> 
    <name>TRP_USERS</name> 
    <statement>CREATE TABLE IF NOT EXISTS TRP_USERS (USER_ID INTEGER PRIMARY KEY AUTOINCREMENT,USER_NAME TEXT,PASSWORD TEXT,CREATION_DATE DATE)</statement> 
  </table> 
<tables> 
<?xml version="1.0"?>
<tables>
  <table>
    <name>TRP_USERS</name>
    <statement>CREATE TABLE IF NOT EXISTS TRP_USERS (USER_ID INTEGER PRIMARY KEY AUTOINCREMENT,USER_NAME TEXT,PASSWORD TEXT,CREATION_DATE DATE)</statement>
  </table>
<tables>

运行时会报错：类似空方法的错误

调试结果：

在BaseTable.xml中

添加一个<table></table>节点，则不会再报错。

猜想：可能是当xml文件解析结果只有一个节点时无法识别ArrayCollection。
