1. 联系人管理

1. 清单文件添加权限

在AndroidManifest.xml中添加权限

<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.WRITE_CONTACTS" />

2. 创建Activity

1. 创建xml文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center">
    <Button
        android:id="@+id/get_contact"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="查询联系人"/>
    <Button
        android:id="@+id/update_contact"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="更新联系人"/>
    <Button
        android:id="@+id/insert_contact"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="插入联系人"/>
    <Button
        android:id="@+id/del_contact"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="删除联系人"/>
</LinearLayout>

2. 创建Activity

创建Activity文件

package com.example.myapplication.prodiver

import android.content.ContentUris
import android.content.ContentValues
import android.content.pm.PackageManager
import android.net.Uri
import android.os.Bundle
import android.provider.ContactsContract
import android.util.Log
import androidx.appcompat.app.AppCompatActivity
import androidx.core.app.ActivityCompat
import com.example.myapplication.R
import com.example.myapplication.utils.ToastUtil
import kotlinx.android.synthetic.main.activity_content_provider.*

class TestContentProviderActivity: AppCompatActivity() {
   
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        // 绑定xml文件
        setContentView(R.layout.activity_content_provider)
    }
    
}

清单文件中添加注册

<application>
	<activity android:name=".prodiver.TestContentProviderActivity">
</application>

添加按钮点击事件

class TestContentProviderActivity: AppCompatActivity() {
   
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        // 绑定xml文件
        setContentView(R.layout.activity_content_provider)
        initView()
    }
    
    private fun initView(){
        get_contact.setOnClickListener {
            getContacts()
        }

        update_contact.setOnClickListener {
            updateContacts()
        }

        insert_contact.setOnClickListener {
            addContacts()
        }

        del_contact.setOnClickListener {
            delContacts()
        }
    }
    
    private fun getContacts(){}
    private fun updateContacts(){}
    private fun addContacts(){}
    private fun delContacts(){}
}

添加权限认证操作

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_content_provider)
    initView()
    var readFlag = ActivityCompat.checkSelfPermission(this, readContacts) != PackageManager.PERMISSION_GRANTED
    var writeFlag = ActivityCompat.checkSelfPermission(this, writeContacts) != PackageManager.PERMISSION_GRANTED
    if(readFlag && writeFlag){

        if(ActivityCompat.shouldShowRequestPermissionRationale(this,readContacts)){
            //引导用户打开读取联系人权限
        }

        ActivityCompat.requestPermissions(this,
                                          arrayOf(readContacts,writeContacts),
                                          100
                                         )

    }else{
        //getContacts()
    }
}

添加权限申请回调

override fun onRequestPermissionsResult(
    requestCode: Int,
    permissions: Array<out String>,
    grantResults: IntArray
) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults)
    // 这个需要与上边的 ActivityCompat.requestPermissions 最后一个参数一致
    if(requestCode == 100){
        if(grantResults.contains(PackageManager.PERMISSION_GRANTED)){
            if(permissions.contains(readContacts) && permissions.contains(writeContacts)){
                ToastUtil.makeTextShowLong(this,"获取读写通讯录权限成功")
            }else{

                if(permissions.contains(readContacts)){
                    ToastUtil.makeTextShowLong(this,"获取读取通讯录权限成功")
                }else{
                    ToastUtil.makeTextShowLong(this,"获取读取通讯录权限失败")
                }

                if(permissions.contains(writeContacts)){
                    ToastUtil.makeTextShowLong(this,"获取写入通讯录权限成功")
                }else{
                    ToastUtil.makeTextShowLong(this,"获取写入通讯录权限失败")
                }
            }
        }else{
            ToastUtil.makeTextShowLong(this,"用户拒绝授权")
        }

    }
}

3. 查询联系人

表名	说明
content://com.android.contacts/data/phones	读取联系人的表的名字

字段	说明
display_name	用户名
data1	手机号

代码

private fun getContacts(){
    ToastUtil.makeTextShowLong(this,"获取联系人")
    var contentResolver = contentResolver
    val uri =Uri.parse("content://com.android.contacts/data/phones")
    var query = contentResolver.query(uri, null, null, null, null)!!
    while(query.moveToNext()){
        // 这里需要传入下标
        var name = query.getString(
            // 这里的参数是string类型的，如果嫌变量名太长可以直接写字符串
            query.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME) ?: 0
        )
        var phone = query.getString(
            query.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER) ?: 0
        )
        ToastUtil.makeTextShowLong(this,"$name,$phone")
        Log.e("$this","$name,$phone")
    }
    query.close()
}

运行结果

姓名:china unicom
号码:10010
======================
姓名:zhang san
号码:10086

4. 插入联系人

插入联系人需要有写入权限

<uses-permission android:name="android.permission.WRITE_CONTACTS"/>

表名	说明
content://com.android.contacts/data/data	插入联系人的表的名字
content://com.android.contacts/data/raw_contacts	插入联系人的原始表的名字

代码

private fun addContacts() {
    val values = ContentValues()
    /*
         * 首先向RawContacts.CONTENT_URI执行一个空值插入，目的是获得系统返回的rawContactId
         * 这时后面插入data表的数据，才能使插入的联系人在通讯录里面可见
         */
    val rawContactUri: Uri = contentResolver!!.insert(RawContacts.CONTENT_URI, values)!!
    val rawContactId = ContentUris.parseId(rawContactUri)

    //往data表里写入姓名数据
    values.clear()
    values.put(ContactsContract.Data.RAW_CONTACT_ID, rawContactId)
    values.put(ContactsContract.Data.MIMETYPE, StructuredName.CONTENT_ITEM_TYPE) //内容类型
    values.put(StructuredName.GIVEN_NAME, "李四")
    contentResolver.insert(ContactsContract.Data.CONTENT_URI, values)

    //往data表里写入电话数据
    values.clear()
    values.put(ContactsContract.Data.RAW_CONTACT_ID, rawContactId)
    values.put(ContactsContract.Data.MIMETYPE, Phone.CONTENT_ITEM_TYPE)
    values.put(Phone.NUMBER, "13921009789")
    values.put(Phone.TYPE, Phone.TYPE_MOBILE)
    contentResolver.insert(ContactsContract.Data.CONTENT_URI, values)

    //往data表里写入Email的数据
    values.clear()
    values.put(ContactsContract.Data.RAW_CONTACT_ID, rawContactId)
    values.put(ContactsContract.Data.MIMETYPE, Email.CONTENT_ITEM_TYPE)
    values.put(Email.DATA, "lisi@qq.com")
    values.put(Email.TYPE, Email.TYPE_WORK)
    contentResolver
    .insert(ContactsContract.Data.CONTENT_URI, values)
}

5. 更新联系人

首先需要获取联系人的contact_id

private fun getContentIdPyPhone(phone: Long): String?{
    val uri =Uri.parse("content://com.android.contacts/data/phones/filter/$phone")
    val cursor = contentResolver.query(
        uri,
        arrayOf(ContactsContract.Data.CONTACT_ID),
        null,
        null,
        null
    )!!
    if (cursor.moveToFirst()) {
        return cursor.getString(0)
    }
    return ""
}

更新联系人信息

private fun updateContacts(){
    ToastUtil.makeTextShowLong(this,"编辑联系人")
    var idPyPhone = getContentIdPyPhone(17663702529L)
    if(idPyPhone == null){
        ToastUtil.makeTextShowShort(this,"联系人不存在")
    }
    val values = ContentValues()
    values.put(ContactsContract.Data.MIMETYPE,
               ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE
              ) //内容类型
    values.put(ContactsContract.CommonDataKinds.StructuredName.GIVEN_NAME, "lisi")
    contentResolver.update(
        Uri.parse("content://com.android.contacts/data"),
        values,
        "${ContactsContract.Data.CONTACT_ID}=?",
        arrayOf(idPyPhone)
    )
}

6. 删除联系人

根据姓名删除联系人

contentResolver.delete(RawContacts.CONTENT_URI,CommonDataKinds.Phone.DISPLAY_NAME+"=?", arrayOf("test"));

根据手机号删除联系人

val contact_id = getContactIdByPhone(18854285999L)

contentResolver.delete(RawContacts.CONTENT_URI,
                       CommonDataKinds.Phone.CONTACT_ID+"=?", 		
                       arrayOf(contact_id));

2. 读取短信

短信相关的其它操作uri

content://sms/ 所有短信

content://sms/inbox 收件箱

content://sms/sent 已发送

content://sms/draft 草稿

content://sms/outbox 发件箱

content://sms/failed 发送失败

content://sms/queued 待发送列表

字段	说明
address	发件人地址，即手机号，如+8613811810000
person	发件人地址，即手机号，如+8613811810000
date	日期，long型，如1256539465022，可以对日期显示格式进行设置
protocol	协议0 ：SMS_RPOTO短信，1:MMS_PROTO彩信
