Android正确获取手机联系人姓名+手机号码

最近项目需要用到获取手机联系人的功能，百度了一下，写这篇文章不是为了充当大神，只是为了自己以后好直接拿来用，用句伟人的话“不要重复找轮子”。

1、首先添加权限

  <!-- 读取联系人权限 -->
  <uses-permission   android:name="android.permission.READ_CONTACTS"/>

2、

  //得到ContentResolver对象
  ContentResolver cr = getContentResolver();
  //取得电话本中开始一项的光标
  Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
  //向下移动光标
  while(cursor.moveToNext())
  {
    //取得联系人名字
    int nameFieldColumnIndex = cursor.getColumnIndex(ContactsContract.PhoneLookup.DISPLAY_NAME);
    String contact = cursor.getString(nameFieldColumnIndex);
    //取得电话号码
    String ContactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
    Cursor phone = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=" + ContactId, null, null);

    while(phone.moveToNext())
    {
        String PhoneNumber = phone.getString(phone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
        //格式化手机号
        PhoneNumber = PhoneNumber.replace("-","");
        PhoneNumber = PhoneNumber.replace(" ","");
    }
}
