问题 There have been several questions on SO regarding getting Contacts numbers using the Contacts API but I'd like to know if there is a way to identify that the number retrieved is a mobile number. The following code is often shown as a way to get a Contact's phone numbers, as it gets a list of one or more phone numbers: String[] projection = {ContactsContract.Contacts._ID, ContactsContract.Contacts.DISPLAY_NAME, ContactsContract.Contacts.HAS_PHONE_NUMBER}; String selection = ContactsContract

问题 I'm creating a Windows 8 Metro App with c# In the app you can search persons in a phonebook. Is there a possibility to add a found contact to the users contact-list? I know you can browse the contacts with the Windows.ApplicationModel.Contacts.Provider, but I can't see how you can add a contact. thanks for help 回答1: You can do so through the Contact Picker Contract. Use ContactPickerUI.AddContact. This will bring up a UI that the user can use to add the Contact you hand it. You cannot add a

WP8.1 C# Binding Contact Image

问题 Information Quite simply, I’m attempting to create an app that would display the contacts for a user. I’m also a self-taught programmer, so I have experience with programming in some aspects, but I am relatively new to data-binding in general. To begin, I have a ListView control that has an image binding within it. <ListView x:Name="ContactsView" ItemsSource="{Binding}"> <ListView.ItemTemplate> <DataTemplate> <Image x:Name="ContactImage" Source="{Binding Converter={StaticResource

深入分析Parquet列式存储格式

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 原文地址 Parquet是面向分析型业务的列式存储格式,由Twitter和Cloudera合作开发,2015年5月从Apache的孵化器里毕业成为Apache顶级项目,最新的版本是1.8.0。 列式存储 列式存储和行式存储相比有哪些优势呢? 可以跳过不符合条件的数据,只读取需要的数据,降低IO数据量。 压缩编码可以降低磁盘存储空间。由于同一列的数据类型是一样的,可以使用更高效的压缩编码(例如Run Length Encoding和Delta Encoding)进一步节约存储空间。 只读取需要的列,支持向量运算,能够获取更好的扫描性能。 当时Twitter的日增数据量达到压缩之后的100TB+,存储在HDFS上,工程师会使用多种计算框架(例如MapReduce, Hive, Pig等)对这些数据做分析和挖掘;日志结构是复杂的嵌套数据类型,例如一个典型的日志的schema有87列,嵌套了7层。所以需要设计一种列式存储格式,既能支持关系型数据(简单数据类型),又能支持复杂的嵌套类型的数据,同时能够适配多种数据处理框架。 关系型数据的列式存储,可以将每一列的值直接排列下来,不用引入其他的概念,也不会丢失数据。关系型数据的列式存储比较好理解,而嵌套类型数据的列存储则会遇到一些麻烦。如图1所示

Provide the caller id for incoming call from my own app

问题 I want to write an App that can identify the phone number of incoming (unknown) calls by looking into a table inside my app (e.g. an SQLite Database Table). I already implemented this in iOS using a Call Directory Extension, but for Android the only option I can find is using a BroadcastReceiver with a popup above the native incoming call screen to show contact information. ContactsContract.Directory seems to offer the possibility to create custom directories where the native call app could
