Android手机的通讯录联系人全部都存在系统的数据库中,如果须要获得通讯里联系人的信息就须要访问系统的数据库,才能将信息拿出来。 这一篇文章我主要带领同学们熟悉Android的通讯录机制。
图中选中的数据库 contacts2.db就是系统储存联系人的数据库,我们将它打开看看里面储存了些什么?
raw_contact_id:通过raw_contact_id可以找到 raw_contact表中相对的数据。
data1 到 data15 这里保存着联系人的信息 联系人名称 联系人电话号码 电子邮件 备注 等等。先说说 Phone.CONTENT_URI,获取联系人的时候需要去这个url中去找数据 。它所指向的其实是“content:// com.android.contacts/data/phones”。这个url 对应着contacts表 和 raw_contacts表 以及 data表 所以说我们的数据都是从这三个表中获取的。
- private static final String[] PHONES_PROJECTION = new String[] {
- Phone.DISPLAY_NAME, Phone.NUMBER, Photo.PHOTO_ID,Phone.CONTACT_ID };
- /**得到手机通讯录联系人信息**/
- private void getPhoneContacts() {
- ContentResolver resolver = mContext.getContentResolver();
- // 获取手机联系人
- Cursor phoneCursor = resolver.query(Phone.CONTENT_URI,PHONES_PROJECTION, null, null, null);
- if (phoneCursor != null) {
- while (phoneCursor.moveToNext()) {
- //得到手机号码
- String phoneNumber = phoneCursor.getString(PHONES_NUMBER_INDEX);
- //当手机号码为空的或者为空字段 跳过当前循环
- if (TextUtils.isEmpty(phoneNumber))
- continue;
- //得到联系人名称
- String contactName = phoneCursor.getString(PHONES_DISPLAY_NAME_INDEX);
- //得到联系人ID
- Long contactid = phoneCursor.getLong(PHONES_CONTACT_ID_INDEX);
- //得到联系人头像ID
- Long photoid = phoneCursor.getLong(PHONES_PHOTO_ID_INDEX);
- //得到联系人头像Bitamp
- Bitmap contactPhoto = null;
- //photoid 大于0 表示联系人有头像 如果没有给此人设置头像则给他一个默认的
- 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();
- }
- }
