在之前项目中有用到关于获取手机联系人的部分，闲置就想和大家分享一下，话不多说，上代码:

java部分:

package com.example.content;
    
    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){
            Uri uri=Uri.parse("content://com.android.contacts/raw_contacts");
            Cursor cursor=cr.query(uri,null,null,null,null);
            while(cursor.moveToNext()){
                int _id=cursor.getInt(cursor.getColumnIndex("_id"));
                String display_name=cursor.getString(cursor.getColumnIndex("display_name"));
                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()){
                    String mimetype=cursorData.getString(cursorData.getColumnIndex("mimetype"));
                    String data1=cursorData.getString(cursorData.getColumnIndex("data1"));
                    if("vnd.android.cursor.item/phone_v2".equals(mimetype)){
                        Log.i("test","     "+mimetype+" "+data1);
                    }
                }
            }
        }
    }

xml部分：

<?xml version="1.0" encoding="utf-8"?>
    <LinearLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
        android:layout_height="match_parent" tools:context="com.example.content.MainActivity">
    
        <Button
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="获取手机联系人"
            android:onClick="getContacts"
            />
    
    </LinearLayout>

在需要获取系统的东西的时候一定不要忘记给权限啊

AndroidManifest.xml部分：

<?xml version="1.0" encoding="utf-8"?>
    <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.content">
    
        
        <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>
