可以先看看思维导图：

然后我们直接上代码：

界面的xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout    xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"    android:layout_height="match_parent"    tools:context="com.example.g160628_26_contentresolver_addressbook.MainActivity">    <Button        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="获取通讯录"        android:onClick="getContacts"/></LinearLayout>

Java类：MainActivity.java

package com.example.g160628_26_contentresolver_addressbook;import android.content.ContentResolver;import android.database.Cursor;import android.net.Uri;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.util.Log;import android.view.View;public class MainActivity extends AppCompatActivity {    private ContentResolver cr;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        //获取内容访问者        cr = getContentResolver();    }    public void getContacts(View view){        //获取通讯录的数据        Uri uri=Uri.parse("content://com.android.contacts/raw_contacts");            Cursor cursor=cr.query(uri,null,null,null,null);        while (cursor.moveToNext()){            //拿到ID            int _id=cursor.getInt(cursor.getColumnIndex("_id"));            //拿到名字            String display_name=cursor.getString(cursor.getColumnIndex("display_name"));            //打印            Log.i("test",_id+"  "+display_name);            Uri uriData=Uri.parse("content://com.android.contacts/raw_contacts/"+_id+"/data");            Cursor cursorData=cr.query(uriData,null,null,null,null);            while (cursorData.moveToNext()){                //拿到类型                String mimetype=cursorData.getString(cursorData.getColumnIndex("mimetype"));                //拿到电话号码                String data1=cursorData.getString(cursorData.getColumnIndex("data1"));                //打印                Log.i("test","     "+data1);            }        }    }}

当然还得有权限所以要配置

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="com.example.g160628_26_contentresolver_addressbook">    <!--获取手机的联系人-->    <uses-permission android:name="android.permission.READ_CONTACTS"></uses-permission>    <application android:allowBackup="true" android:icon="@mipmap/ic_launcher"        android:label="@string/app_name" android:roundIcon="@mipmap/ic_launcher_round"        android:supportsRtl="true" android:theme="@style/AppTheme">        <activity android:name=".MainActivity">            <intent-filter>                <action android:name="android.intent.action.MAIN" />                <category android:name="android.intent.category.LAUNCHER" />            </intent-filter>        </activity>    </application></manifest>

当然这里也会有些手机行不通不过这应该是手机中权限的问题吧一般的都可以
