Android 本地推送消息到通知栏 NotificationManager 注册Android Service

               

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。
