ContentProvider扩展之管理系统联系人

我们都知道ContentProvider是用来共享数据的,然而android本身就提供了大量的ContentProvider,例如联系人信息,系统的多媒体信息等,这些系统的ContentProvider都提供了供其他应用程序访问的Uri,开发者可以通过ContentResolver来调用系统的ContentProvider提供的insert()/update()/delete()/query()方法,从而实现自己的需求。

1、了解系统联系人的结构

(1)android系统对联系人管理提供了很多的Uri,其中用到最多的几个如下:

  ContactsContract.Contacts.CONTENT_URI:管理联系人的Uri

  ContactsContract.CommonDataKinds.Phone.CONTENT_URI:管理联系人电话的Uri

  ContactsContract.CommonDataKinds.Email.CONTENT_URI:管理联系人邮箱的Uri

  ContactsContract.CommonDataKinds.StructuredPostal.CONTENT_URI:管理联系人地址的Uri

  我们可以根据系统提供的这些Uri去操作系统联系人信息,具体的还有很多CONTENT_URI,可以到ContactsContract.class文件中去查看源码。

(2)表结构

  我们之前说过,ContentProvider是以表的形式来存放这些数据的,系统联系人也是这样,一般存放在data/data/com.android.providers.contacts/databases/contacts2.db中,我们可以通过adb shell命令行的方式来看,也可以将这个contacts2.db文件导出,通过sqlite工具来查看,这里为了方便我们导出来看一下。

找到对应的文件,然后选中点击右上角的导出按钮,将文件导出到系统中的某一个地方

将导出的文件用工具打开,我这里使用的是:Navicat Premium

我们经常用的到有:contacts、data、raw_contacts三张表:

contacts表:

  _id :表的ID,主要用于其它表通过contacts 表中的ID可以查到相应的数据。
  display_name: 联系人名称
  photo_id:头像的ID,如果没有设置联系人头像,这个字段就为空
  times_contacted:通话记录的次数
  last_time_contacted: 最后的通话时间 
  lookup :是一个持久化的储存 因为用户可能会改名子 但是它改不了lookup

data表:

  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

技术分享

raw_contacts表:

   version :版本号,用于监听变化
  deleted :删除标志, 0为默认 1 表示这行数据已经删除
  display_name : 联系人名称
  last_time_contacts : 最后联系的时间

 【说明:由于这些表的字段都特别多,截图不全,可以自己试着导出一份看看】

2、代码实现

(1)首先要在AndroidManifest.xml文件中配置对系统联系人的读写权限:

<!-- 添加操作联系人的权限 -->
    <uses-permission android:name="android.permission.READ_CONTACTS" />
    <uses-permission android:name="android.permission.WRITE_CONTACTS" />

(2)布局文件

  首先是列表展示页面:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <TextView
        android:layout_width="fill_parent"
        android:layout_height="50dp"
        android:gravity="center_vertical"
        android:text="我的联系人"
        android:textSize="25dp" />

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        android:background="@android:color/darker_gray" >

        <TextView
            android:id="@+id/id"
            android:layout_width="0dp"
            android:layout_height="30dp"
            android:layout_weight="1"
            android:text="ID"
            android:gravity="center" />

        <TextView
            android:id="@+id/name"
            android:layout_width="0dp"
            android:layout_height="30dp"
            android:layout_weight="1"
            android:text="姓名"
            android:gravity="center" />

        <TextView
            android:id="@+id/phone"
            android:layout_width="0dp"
            android:layout_height="30dp"
            android:layout_weight="1"
            android:text="手机号码"
            android:gravity="center" />
        
    </LinearLayout>

    <ListView
        android:id="@+id/listview"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:divider="#FF0000"
        android:dividerHeight="1dp"
        android:focusable="true"
        android:minHeight="40dp"
        android:footerDividersEnabled="false" >
    </ListView>

</LinearLayout>
