检查一下是添加了READ_CONTACTS权限吗？添加的位置对吗？

搞了个乌龙，原来是我的手机在程序请求权限的时候没授予，所以没得到列表，但现在仍有个问题，就是号码取不出来，名字到取出来了

Permission Denial

还是没权限的问题。

号码取不出来估计是你字段搞作了。

遇到任何和系统功能有关的功能的时候都要注意加权限

Couldn't read row 0, col -1 from CursorWindow。
不能从cursor视窗中读取第0行第-1列，
把nameFieldColumnIndex,numberFieldColumnIndex这两个int打印出来看看

调查完了，这个cursor中貌似没有PhoneLookup.NUMBER这个字段，你把它去掉，就好了
