Android ContentResolver ContactsContract 获取手机联系人信息

获取手机联系人信息步骤：
1、获取 ContentResolver
ContentResolver resolver = getContentResolver();
2、resolver.query(*)查询信息
查询手机联系人的URI：ContactsContract.RawContacts.CONTENT_URI
查询手机联系人手机号的URI：ContactsContract.CommonDataKinds.Phone.CONTENT_URI
查询联系人邮箱的URI：ContactsContract.CommonDataKinds.Email.CONTENT_URI
3、根据联系人名字的_id查询对应的手机号和邮箱
在手机号和邮箱查询中找到raw_contact_id与联系人的_id相等的条目

主要代码如下：

读取联系人的权限：

<uses-permission android:name="android.permission.READ_CONTACTS"/>

最终效果图：

注意：

1. 注意检查是否赋予了应用读取联系人的权限；
2. 本例在主线程中读取联系人信息，效率不高，如有效率要求，请自行寻找其他方法。
