Android 获取手机通讯录联系人信息-Toy模板网

这篇具有很好参考价值的文章主要介绍了Android 获取手机通讯录联系人信息。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

近日在项目开发过程中发现，华为手机HarmonyOS 3.0系统，设置>隐私里面可以查看各个应用访问隐私权限的次数，发现应用程序访问手机通讯录的次数异常的高，针对访问通讯录频次高的问题做了研究和优化

问题分析：

分析代码发现只要通过ContentProvider 访问通讯录一次，统计次数就响应增加一次

ContentResolver resolver = context.getContentResolver();
Cursor cursor = resolver.query(ContactsContract.Data.CONTENT_URI, null, null, null, null);

代码中获取联系人头像、邮箱、号码、公司信息等都调用了query 方法，因此查询一个联系人的信息访问了多次通讯录，因此对获取联系人的方法做了改进，改进如下：

一、权限声明

AndroidManifest.xml文件中声明权限如下：

    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />    获取联系人权限
    <uses-permission android:name="android.permission.READ_CONTACTS" />      文件读写权限

二、新建联系人信息类

import java.util.ArrayList;
import java.util.List;

三、获取联系人信息

调用方法前先检查读取联系人权限 android.Manifest.permission.READ_CONTACTS，

如果要保存联系人头像到SD卡目录下还需检查文件读写权限 android.Manifest.permission.WRITE_EXTERNAL_STORAGE

import android.content.ContentResolver;
import android.content.Context;
import android.database.Cursor;
import android.provider.ContactsContract;
import android.util.Log;

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.Map;

/**

public class ContactsLoadUtil {
    public static final String TAG = "ContactsLoadUtil";

    /**

            Log.d(TAG, "mk photo dir: " + mkdirs);
        }

以上就是获取联系人信息的详细代码，如果大家还需要获取其他信息的话，可以查看Android SDK 源码，根据源码里面的注释去获取更多的信息。

以上代码实现仅供大家参考，希望对大家有所帮助文章来源地址https://www.toymoban.com/news/detail-530586.html
