获取手机通讯录的简单实现

直接上代码：

在AndroidManifest.xml 中添加权限

xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.palmv.getcontacts">
    
    android:name="android.permission.READ_CONTACTS"/>
    
    android:name="android.permission.CALL_PHONE"/>

新增一个实体类：ContactEntity

package com.palmv.getcontacts;

import android.graphics.Bitmap;

/**
 * @author：chendd
 * @date：2016/7/14
 * @description：
 */
public class ContactEntity {
    /** 联系人名称 **/
    private String name;
    /** 联系人号码 **/
    private String number;
    /** 联系人头像 **/
    private Bitmap photo;

    @Override
    public String toString() {
        return "ContactEntity{" +
                "name='" + name + '\'' +
                ", number='" + number + '\'' +
                ", photo=" + photo +
                '}';
    }

    public ContactEntity(String name, String number, Bitmap photo) {
        this.name = name;
        this.number = number;
        this.photo = photo;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getNumber() {
        return number;
    }

    public void setNumber(String number) {
        this.number = number;
    }

    public Bitmap getPhoto() {
        return photo;
    }

    public void setPhoto(Bitmap photo) {
        this.photo = photo;
    }
}

在activity中直接调用获取通讯录

package com.palmv.getcontacts;

import android.content.ContentResolver;
import android.content.ContentUris;
import android.database.Cursor;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.net.Uri;
import android.os.Bundle;
import android.provider.ContactsContract;
import android.support.v7.app.AppCompatActivity;
import android.text.TextUtils;

import java.io.InputStream;
import java.util.ArrayList;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        getPhoneContacts();

    }
    /** 联系人名称 **/
    private ArrayList mContacts = new ArrayList();

    private static final String[] PHONES_PROJECTION = new String[] {
            ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME,
            ContactsContract.CommonDataKinds.Phone.NUMBER,
            ContactsContract.CommonDataKinds.Phone.PHOTO_ID,
            ContactsContract.CommonDataKinds.Phone.CONTACT_ID };

    /** 联系人显示名称 **/
    private static final int PHONES_DISPLAY_NAME_INDEX = 0;

    /** 电话号码 **/
    private static final int PHONES_NUMBER_INDEX = 1;

    /** 头像ID **/
    private static final int PHONES_PHOTO_ID_INDEX = 2;

    /** 联系人的ID **/
    private static final int PHONES_CONTACT_ID_INDEX = 3;

    private void getPhoneContacts() {
        ContentResolver resolver = getContentResolver();
        try {
            // 获取手机联系人
            Cursor phoneCursor = resolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
                    PHONES_PROJECTION, null, null, null);
            if (phoneCursor != null) {
                while (phoneCursor.moveToNext()) {

                    // 得到手机号码
                    String phoneNumber = phoneCursor
                            .getString(PHONES_NUMBER_INDEX);
                    // 当手机号码为空的或者为空字段 跳过当前循环
                    if (TextUtils.isEmpty(phoneNumber))
                        continue;
                    System.out.println("======================");
                    System.out.println("---手机号码："+phoneNumber);


                    // 得到联系人名称
                    String contactName = phoneCursor
                            .getString(PHONES_DISPLAY_NAME_INDEX);
                    System.out.println("---联系人："+contactName);

                    // 得到联系人ID
                    Long contactid = phoneCursor
                            .getLong(PHONES_CONTACT_ID_INDEX);
                    System.out.println("---联系人id："+contactid);

                    // 得到联系人头像ID
                    Long photoid = phoneCursor.getLong(PHONES_PHOTO_ID_INDEX);
                    System.out.println("---联系人头像："+photoid);

                    // 得到联系人头像Bitamp
                    Bitmap contactPhoto = null;

                    // photoid 大于0 表示联系人有头像 如果没有给此人设置头像则给他一个默认的
                    if (photoid > 0) {
                        Uri uri = ContentUris.withAppendedId(
                                ContactsContract.Contacts.CONTENT_URI,
                                contactid);
                        InputStream input = ContactsContract.Contacts
                                .openContactPhotoInputStream(resolver, uri);
                        contactPhoto = BitmapFactory.decodeStream(input);
                        System.err.println("---联系人有头像："+photoid);
                    } else {
                        contactPhoto = BitmapFactory.decodeResource(
                                getResources(), R.mipmap.ic_launcher);
                    }
                    ContactEntity mContact = new ContactEntity(contactName,
                            phoneNumber, contactPhoto);
                    mContacts.add(mContact);
                }
                phoneCursor.close();
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

运行结果下图：
