android開發怎樣獲取通訊錄聯系人信息

private void getPhoneContacts() {

ContentResolver resolver = mContext.getContentResolver();

// 獲取手機聯系人

Cursor phoneCursor = resolver.query(Phone.CONTENT_URI,PHONES_PROJECTION, null, null, null);

if (phoneCursor != null) {

while (phoneCursor.moveToNext()) {

//得到手機號碼

String phoneNumber = phoneCursor.getString(PHONES_NUMBER_INDEX);

//當手機號碼為空的或者為空字段 跳過當前循環

if (TextUtils.isEmpty(phoneNumber))

continue;

//得到聯系人名稱

String contactName = phoneCursor.getString(PHONES_DISPLAY_NAME_INDEX);

//得到聯系人ID

Long contactid = phoneCursor.getLong(PHONES_CONTACT_ID_INDEX);

//得到聯系人頭像ID

Long photoid = phoneCursor.getLong(PHONES_PHOTO_ID_INDEX);

//得到聯系人頭像Bitamp

Bitmap contactPhoto = null;

//photoid 大於0 表示聯系人有頭像 如果沒有給此人設置頭像則給他壹個默認的

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 = BitmapFactory.decodeResource(getResources(), R.drawable.contact_photo);

}

mContactsName.add(contactName);

mContactsNumber.add(phoneNumber);

mContactsPhonto.add(contactPhoto);

}

phoneCursor.close();

}

}
