Android java后台运行活动

我正在创建通知，并在通知中添加“addAction”。 我想在单击“addAction”时，删除通知并运行另一个代码。 我怎么能做到

 Intent intent = new Intent(context, Activity.class);
                    PendingIntent pi = PendingIntent.getActivity(context, 0, intent,PendingIntent.FLAG_UPDATE_CURRENT);
.........
 .addAction(R.drawable.eye, "View", pi)

我想在后台运行Activity.class，我的意思是此活动未打开，但此活动中的代码正在运行。

我如何做到这一点？

如果你想在后台运行代码，你必须创建一个服务

 Intent intent = new Intent(context, Activity.class);
                    PendingIntent pi = PendingIntent.getActivity(context, 0, intent,PendingIntent.FLAG_UPDATE_CURRENT);
.........
 .addAction(R.drawable.eye, "View", pi)

前

服务代码

package com.javatechig.serviceexample;

import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.util.Log;

public class HelloService extends Service {

    private static final String TAG = "HelloService";

    private boolean isRunning  = false;

    @Override
    public void onCreate() {
        Log.i(TAG, "Service onCreate");

        isRunning = true;
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {

        Log.i(TAG, "Service onStartCommand");

        //Creating new thread for my service
        //Always write your long running tasks in a separate thread, to avoid ANR
        new Thread(new Runnable() {
            @Override
            public void run() {


                //Your logic that service will perform will be placed here
                //In this example we are just looping and waits for 1000 milliseconds in each loop.
                for (int i = 0; i < 5; i++) {
                    try {
                        Thread.sleep(1000);
                    } catch (Exception e) {
                    }

                    if(isRunning){
                        Log.i(TAG, "Service running");
                    }
                }

                //Stop service once it finishes its task
                stopSelf();
            }
        }).start();

        return Service.START_STICKY;
    }


    @Override
    public IBinder onBind(Intent arg0) {
        Log.i(TAG, "Service onBind");
        return null;
    }

    @Override
    public void onDestroy() {

        isRunning = false;

        Log.i(TAG, "Service onDestroy");
    }
}

你不可能是认真的…要在后台运行某些东西，你应该做一个服务，而不是一个活动。

Intent intent = new Intent(this, HelloService.class);
startService(intent);
