2.0联系人增、删、改、查

本章和大家分享的是手机通讯录方面的经验，需求背景:对手机通讯录进行增、删、改、查，或者有时候App需要与手机 contacts进行交互或共享contacts。
我们都知道android系统没有完全将contacts向developer开放，开发人员只能通过android提供的有限的Api对contacts进行操作，我们只能通过ContentProvider对contacts的数据进行增、删、改、查等操作，并不能改变到其表结构。
首先，我们来看下如何通过ContentProvider查找contacts，以下我以查找其姓、名、公司、家庭电话、工作电话、移动电话、传真、邮箱、城市、省份、国家、出生年月为例：
 
 
 /**
  * 取得family_name和given_name
  */
 Cursor nameCur=cr.query(ContactsContract.Data.CONTENT_URI,
   new String[] {Data.CONTACT_ID, StructuredName.DISPLAY_NAME, StructuredName.FAMILY_NAME, StructuredName.GIVEN_NAME, StructuredName.MIDDLE_NAME},
    ContactsContract.Data.CONTACT_ID + "=?" + " AND "
          + ContactsContract.Data.MIMETYPE + "='" +  ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE + "'",
   new String[]{android_id}, null);
 if(nameCur.moveToFirst()){
  firstName=nameCur.getString(nameCur.getColumnIndex(ContactsContract.CommonDataKinds.StructuredName.FAMILY_NAME));
  lastName=nameCur.getString(nameCur.getColumnIndex(ContactsContract.CommonDataKinds.StructuredName.GIVEN_NAME));
 }
 nameCur.close();
 
 Cursor companyCur=cr.query(ContactsContract.Data.CONTENT_URI,
   new String[] {CommonDataKinds.Organization.COMPANY},
    ContactsContract.Data.CONTACT_ID + "=?" + " AND "
          + ContactsContract.Data.MIMETYPE + "='" +  ContactsContract.CommonDataKinds.Organization.CONTENT_ITEM_TYPE + "'",
   new String[]{android_id}, null);
 
 if(companyCur.moveToFirst()){
   company=companyCur.getString(companyCur.getColumnIndex(CommonDataKinds.Organization.COMPANY));
  }
 companyCur.close();
 
 // 根据contact_ID取得HomePhone号码
 Cursor homePhoneCur = cr.query(ContactsContract.Data.CONTENT_URI,

        new String[]{android_id,ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE,String.valueOf(ContactsContract.CommonDataKinds.Phone.TYPE_HOME)}, null);

 homePhoneCur.close();

 }
 workPhoneCur.close();
 
 // 根据contact_ID取得MobilePhone号码
