这是我的查询

Cursor contact = context.getContentResolver().query(Data.CONTENT_URI,new String[] {Data.RAW_CONTACT_ID},Data.DATA1  + "=" + from,null,null);

什么是错我的语法？它有什么做的 @ ？

推荐答案

尝试把引号的邮件，也就是说，在你的方法调用改变第三个参数

Try putting quotes around your email, ie, change the third parameter in your method call to

Data.DATA1  + "='" + from + "'"
