Android通讯录（6.0）操作简介

添加权限

Android6.0获取手机通讯录动态权限

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
  if (ActivityCompat.checkSelfPermission(getBaseActivity(), Manifest.permission.READ_CONTACTS) != PackageManager.PERMISSION_GRANTED) 
    requestPermissions(new String[]{Manifest.permission.READ_CONTACTS}, 1001);
}

获取权限回调

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
  super.onRequestPermissionsResult(requestCode, permissions, grantResults);
  switch (requestCode) {
    case 1001:
      if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
      }
    break;
  }
}

读取手机联系人通讯录

public class ContactUtils {

  public static List getAllContacts(Context context) {
    List phoneInfoList = new ArrayList();
    ContentResolver resolver = context.getContentResolver();
    Uri uri = ContactsContract.CommonDataKinds.Pohne.CONTENT_URI;
    String[] projection = new String[]{"contact_id", "display_name", "sort_key", "version"};
    if(Build.VERSION.SDK.INT >= 19{
      projection[2] = "phonebook_label"
      Cursor testCursor = null;
      try{
        testCursor = resolver.query(uri, new String[]{"phonebook_label", null, null, null};
      } catch (Exception e){
        projection[2] = "sort_key";
      } finally {
        if(testCursor != null)
          testCursor.close();
      }
    }
    Cursor cursor = resolver.query(uri, projection, null, null, projection[2]);
    if (cursor != null) {
      while (cursor.moveToNext()) {
        PhoneInfo phoneInfo = new PhoneInfo();
        List telPhone = new ArrayList<>();
        int id = cursor.getInt (cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.CONTACT_ID));
        String name = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
        String sortKey = getSortKey(cursor.getString(2));
        long contactVersion = cursor.getLong(cursor.getColumnIndex(ContactsContract.RawContacts.VERSION));

        String[] phoneProjection = new String[]{ContactsContract.CommonDataKinds.Phone.NUMBER};
        String contact_id = ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = " + id;
        Cursor cursorPhone = resolver.query(uri, phoneProjection, contact_id, null, null);
        if (cursorPhone != null) {
          while (cursorPhone.moveToNext()) {
            String phone = cursorPhone.getString(cursorPhone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
            telPhone.add(phone);
          }
        } 
        phoneInfo.setName(name);
        phoneInfo.setSortKey(sortKey);
        phoneInfo.setTelPhoneList(telPhone);
        phoneInfoList.add(phoneInfo);
      }
    }
    return phoneInfoList;
  }

  private static String getSortKey(String sortKeyString) {
    String key = sortKeyString.substring(0, 1).toUpperCase();
    if (key.matches("[A-Z]")) {
      return key;
    } else {
      return "#";
    }
  }
}

共享数据监听

public class ContactContentObserver extends ContentObserver {

    public ContactContentObserver(Handler handler) {
        super(handler);
    }

    @Override
    public void onChange(boolean selfChange) {
        super.onChange(selfChange);
        Log.d("abcd","联系人列表发生变化");
    }
}

注册监听通讯录变化

private void myObserver() {
  observer = new ContactContentObserver(new Handler());
  resolver = getBaseActivity().getContentResolver();
  Uri uri = ContactsContract.Contacts.CONTENT_URI;
  resolver.registerContentObserver(uri, true, observer);
}

取消注册监听

@Override
protected void onDestroy() {
  resolver.unregisterContentObserver(observer);
}
