android 擷取通訊錄連絡人資訊

  android 中擷取通訊錄中連絡人資訊，代碼如下：

  

    /**     * 擷取連絡人資訊,包括：名稱、號碼、頭像     * @return     */    private ArrayList<PhoneContactor> getPhoneContacts(){            Log.i(TAG, "getPhoneContacts");            ContentResolver resolver=this.getContentResolver();        ArrayList<PhoneContactor> list = new ArrayList<PhoneContactor>();             String[] columns = new String[] {Phone.DISPLAY_NAME,Phone.NUMBER,Phone.PHOTO_ID,Phone.CONTACT_ID};            Cursor cursor = resolver.query(Phone.CONTENT_URI, columns, null,null, null);   Bitmap photo_default=BitmapFactory.decodeResource(getResources(), R.drawable.contact_photo_default);           while (cursor.moveToNext()) {                PhoneContactor pc = new PhoneContactor();                                String name=cursor.getString(cursor.getColumnIndex(Phone.DISPLAY_NAME));                                String number=cursor.getString(cursor.getColumnIndex(Phone.NUMBER));                if(TextUtils.isEmpty(number)){ //判斷號碼是否為空白                                continue;                }                                long photoId=cursor.getLong(cursor.getColumnIndex(Phone.PHOTO_ID));                                long contactId=cursor.getLong(cursor.getColumnIndex(Phone.CONTACT_ID));                                //得到連絡人頭像Bitamp                   Bitmap contactPhoto = null;                                //photoId 大於0表示連絡人有頭像，否則設定一個預設頭像                   if(photoId > 0 ) {                                      Uri uri =ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI,contactId);                      InputStream input = ContactsContract.Contacts.openContactPhotoInputStream(resolver, uri);                      contactPhoto = BitmapFactory.decodeStream(input);                                  }else {                                      contactPhoto = photo_default;                 }                                  pc.name(name);                pc.number(number);                pc.photo(contactPhoto);                                list.add(pc);                                 Log.d(TAG, "name:" + pc.name());                Log.d(TAG, "number:" + pc.number());        }                cursor.close();                 return list;    }

其中：PhoneContactor為自訂的儲存連絡人資訊的類，最後別忘了加上許可權：

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