Android Service ，在退出程序之后 ，仍然留在后台作为服务项做一些事情，比如说监听用户输入之类的。。。。

这里用来做后台的消息推送，像游戏中的广告可以这么做。

 

Android工程里面有两个Activity、一个Service重写。

MainActivity 是进入游戏的界面。

SecondActivity 是打开通知，点击推送的消息打开的Activity 。

push_service 是重写的Service 。

 

MainActivity

package com.example.androidnotification;

import android.os.Bundle;
import android.R.integer;
import android.app.Activity;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class MainActivity extends Activity {

    private Button button1;
    private Button button2;

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

        //获取到通知管理器
        NotificationManager mNotificationManager=(NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);

        //定义内容
        int notificationIcon=R.drawable.icon;
        CharSequence notificationTitle="测试通知栏--title";
        long when = System.currentTimeMillis();

        Notification notification=new Notification(notificationIcon, notificationTitle, when);

        notification.defaults=Notification.DEFAULT_ALL;

        Intent intent=new Intent(MainActivity.this,SecondActivity.class);
        PendingIntent pendingIntent=PendingIntent.getActivity(MainActivity.this, 0, intent, 0);
        notification.setLatestEventInfo(this,"测试展开title", "测试展开内容",pendingIntent);

        if(notification!=null)
        {
            Log.e("notifacation", "notifacation is ok");
            mNotificationManager.notify(1000, notification);
        }

        button1=(Button)findViewById(R.id.button1);
        button1.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {
                // TODO Auto-generated method stub
                Intent pushIntent=new Intent("com.example.androidnotification.push_service");
                startService(pushIntent);

            }
        });

        button2=(Button)findViewById(R.id.button2);
        button2.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                MainActivity.this.finish();
            }
        });

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

}

打开程序的时候发送了一个通知。。。

主要就是获取到通知管理器然后新建一个通知，然后发送这个通知！。。。

 

 

SecondActivity 

package com.example.androidnotification;

import android.app.Activity;
import android.os.Bundle;

public class SecondActivity extends Activity {

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

 

第二个Activity只是为了存在而存在，没有啥不懂。。

 

push_service

重写了Service ，注册一个Service 。。

package com.example.androidnotification;

import android.app.Activity;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.app.Service;
import android.content.Context;
import android.content.Intent;
import android.os.Handler;
import android.os.IBinder;
import android.util.Log;

public class push_service extends Service {

    @Override
    public IBinder onBind(Intent arg0) {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public void onCreate()
    {
        super.onCreate();
        Log.i("push_service", "push_service onCreate");
    }

    @SuppressWarnings("deprecation")
    @Override
    public void onStart(Intent intent,int startId)
    {
        super.onStart(intent, startId);
        Log.i("push_service", "push_service start");

        new Thread(new Runnable() {

            @Override
            public void run() {
                // TODO Auto-generated method stub
                try {
                    for (int i = 0; i <100; i++) {
                        Thread.sleep(3000);
                        Log.i("push_service", "push_service foreach");



                        //获取到通知管理器
                        NotificationManager mNotificationManager=(NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);

                        //定义内容
                        int notificationIcon=R.drawable.icon;
                        CharSequence notificationTitle="测试通知栏--title";
                        long when = System.currentTimeMillis();

                        Notification notification=new Notification(notificationIcon, notificationTitle, when);

                        notification.defaults=Notification.DEFAULT_ALL;

                        Intent intent=new Intent(getApplicationContext(),SecondActivity.class);
                        PendingIntent pendingIntent=PendingIntent.getActivity(getApplicationContext(), 0, intent, 0);
                        notification.setLatestEventInfo(getApplicationContext(),"测试展开title", "测试展开内容",pendingIntent);

                        if(notification!=null)
                        {
                            Log.e("notifacation", "notifacation is ok");
                            mNotificationManager.notify(1000+i, notification);
                        }


                    }

                } catch (InterruptedException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }

            }
        }).start();
    }

    @Override
    public void onDestroy()
    {
        super.onDestroy();
        Log.i("push_service", "push_service destroy");
    }

}

 

嗯，把发送通知的代码复制到这里循环几百次。。用来测试退出程序后服务是不是还在跑着。
