app如何獲取通信錄

『壹』 android開發怎樣獲取通訊錄聯系人信息

• 要獲取通訊錄的聯系人信息，只有通過系統聯系人應用的內容提供者，才能訪問到聯系人資料庫，下面有一個代碼演示

• 代碼演示

• java">privateArrayList<HashMap<String,String>>readContact(){
  //首先,從raw_contacts中讀取聯系人的id("contact_id")
  //其次,根據contact_id從data表中查詢出相應的電話號碼和聯系人名稱
  //然後,根據mimetype來區分哪個是聯系人,哪個是電話號碼
  UrirawContactsUri=Uri
  .parse("content://com.android.contacts/raw_contacts");
  UridataUri=Uri.parse("content://com.android.contacts/data");
  ArrayList<HashMap<String,String>>list=newArrayList<>();
  //從raw_contacts中讀取聯系人的id("contact_id")
  CursorrawContactsCursor=getContentResolver().query(rawContactsUri,
  newString[]{"contact_id"},null,null,null);
  if(rawContactsCursor!=null){
  while(rawContactsCursor.moveToNext()){
  StringcontactId=rawContactsCursor.getString(0);
  //System.out.println(contactId);
  //根據contact_id從data表中查詢出相應的電話號碼和聯系人名稱,實際上查詢的是視圖view_data
  CursordataCursor=getContentResolver().query(dataUri,
  newString[]{"data1","mimetype"},"contact_id=?",
  newString[]{contactId},null);
  if(dataCursor!=null){
  HashMap<String,String>map=newHashMap<String,String>();
  while(dataCursor.moveToNext()){
  Stringdata1=dataCursor.getString(0);
  Stringmimetype=dataCursor.getString(1);
  //System.out.println(contactId+";"+data1+";"
  //+mimetype);
  if("vnd.android.cursor.item/phone_v2".equals(mimetype)){
  map.put("phone",data1);
  }elseif("vnd.android.cursor.item/name"
  .equals(mimetype)){
  map.put("name",data1);
  }
  }
  list.add(map);
  dataCursor.close();
  }
  }
  rawContactsCursor.close();
  }
  returnlist;
  }

『貳』 android開發怎樣獲取通訊錄聯系人信息

在Android開發中,我經常會遇到需要獲取手機通訊錄聯系人信息,Android手機的通訊錄聯系人全部都存在系統的資料庫中，如果須要獲得通訊里聯系人的信息就須要訪問系統的資料庫，才能將信息獲取出來。
下面直接貼出代碼供大家參考:
