    Layout

    <?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"
        android:orientation="vertical"
        tools:context="com.example.hzx.myservice.MainActivity">
    
        <Button
            android:id="@+id/start_service"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Start Service"/>
    
        <Button
            android:id="@+id/stop_service"

            android:text="Unbind Service"/>
    
        <Button

            android:text="Start IntetnService"/>
    </LinearLayout>
    
    
    

    新建一个类集成IntentServic

    package com.example.hzx.myservice;
    
    import android.app.IntentService;
    import android.content.Intent;
    import android.support.annotation.Nullable;
    import android.util.Log;
    
    /**
     * Created by hzx on 2018/11/5.
     */
    
    public class MyIntentService extends IntentService {
    
        private static final String TAG = "123";
    
        public MyIntentService(){
            super("MyIntentService");
            Log.d(TAG,"==>MyIntentService");
        }
        @Override
        protected void onHandleIntent(@Nullable Intent intent) {
            Log.d(TAG,"==>Thread id is "+Thread.currentThread().getId());
    
        }
        public void onDestroy(){
            super.onDestroy();
            Log.d(TAG,"==>onDestroy");
        }
    
    }
    
    

    Activity

    package com.example.hzx.myservice;
    
    import android.app.Notification;
    import android.app.PendingIntent;
    import android.content.ComponentName;
    import android.content.Intent;
    import android.content.ServiceConnection;
    import android.graphics.BitmapFactory;
    import android.os.IBinder;
    import android.support.v4.app.NotificationCompat;
    import android.support.v7.app.AppCompatActivity;
    import android.os.Bundle;
    import android.util.Log;
    import android.view.View;
    import android.widget.Button;
    
    public class MainActivity extends AppCompatActivity implements View.OnClickListener{
    
        private final String TAG = "123";
        private MyService.DownloadBinder downloadBinder;
    
        private ServiceConnection connetction = new ServiceConnection() {
            @Override
            public void onServiceConnected(ComponentName componentName, IBinder iBinder) {
                downloadBinder = (MyService.DownloadBinder)iBinder;
                downloadBinder.startDownload();
                downloadBinder.getProgress();
            }
    
            @Override
            public void onServiceDisconnected(ComponentName componentName) {
    
            }
        };
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
    
    
            Button startService = (Button)findViewById(R.id.start_service);
            Button stopService = (Button)findViewById(R.id.stop_service);
    
            startService.setOnClickListener(MainActivity.this);
            stopService.setOnClickListener(MainActivity.this);
    
            Button bingService = (Button)findViewById(R.id.bind_service);
            Button unbindService = (Button)findViewById(R.id.unbind_service);
    
            bingService.setOnClickListener(MainActivity.this);
            unbindService.setOnClickListener(MainActivity.this);
    
    
            Button startIntentService = (Button)findViewById(R.id.start_intent_service);
            startIntentService.setOnClickListener(MainActivity.this);
    
        }
    
        public void onClick(View v){
            switch (v.getId()){
                case R.id.start_service:
                    Log.d(TAG,"activity start_service");
                    Intent startIntent = new Intent(this,MyService.class);
                    startService(startIntent);
                    break;
                case R.id.stop_service:
                    Log.d(TAG,"activity stop_sercie");
                    Intent stopIntent = new Intent(this,MyService.class);
                    stopService(stopIntent);
                    break;
                case R.id.bind_service:
                    Log.d(TAG,"activity bind_service");
                    Intent bindIntent = new Intent(this,MyService.class);
                    bindService(bindIntent,connetction,BIND_AUTO_CREATE);
                    break;
                case R.id.unbind_service:
                    Log.d(TAG,"activity unbind_service");
                    unbindService(connetction);
                    break;
                case R.id.start_intent_service:
                    Log.d(TAG,"activity Thread id is "+Thread.currentThread().getId());
                    Intent intentService = new Intent(this,MyIntentService.class);
                    startService(intentService);
                    break;
                    default:
                        break;
            }
        }
    }
    
    
    

    注意:
    1、 需要在AndroidManifest.xml文件注册
    <service android:name=".MyService" />
    <service android:name=".MyIntentService"/>

    效果
