插入：

  ContentResolver cr =  getContentResolver();
        //向联系人中 插入一行数据
       ContentValues values = new ContentValues();
       Uri uri =  cr.insert(RawContacts.CONTENT_URI, values);
       Long raw_contact_id = ContentUris.parseId(uri);
       values.clear();
       //插入人名
       values.put(StructuredName.RAW_CONTACT_ID, raw_contact_id);
       values.put(StructuredName.DISPLAY_NAME, "张三三");
       values.put(StructuredName.MIMETYPE, StructuredName.CONTENT_ITEM_TYPE);
       uri = cr.insert(Data.CONTENT_URI, values);
       //插入电话信息
       values.clear();
       values.put(Phone.RAW_CONTACT_ID,raw_contact_id);
       values.put(Phone.NUMBER,"13333333333");
       values.put(Phone.MIMETYPE, Phone.CONTENT_ITEM_TYPE);
       uri = cr.insert(Data.CONTENT_URI, values);
