Notification顶部状态栏和下拉任务栏通知

界面很简单，功能也实现的很简单，

一个简单的DEMO，

欢迎转载，请加地址http://blog.csdn.net/jing110fei/article/details/39055809

1主页面

2点击开启发送后

      

设置每隔10秒发送1次直到用户点击通知栏或点击停止发送

点击通知栏，会跳转

首先的一点是，为了能使所有Actvity都能方便的调用同一对象或者方法，我自定义了Application

public class AllApplication extends Application{public ScheduledExecutorService scheduledThreadPool;@Overridepublic void onCreate() {// TODO Auto-generated method stubsuper.onCreate();scheduledThreadPool=null;}}

为了使这个Application生效，需要在AndroidManifest.xml中替换原来的

<application        android:name=".AllApplication"        android:icon="@drawable/ic_launcher"        android:label="@string/app_name"        android:theme="@style/AppTheme" ></application>

不多说，直接上代码，注释就在代码里

首先是两个简单的布局文件

activity_notification_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:orientation="vertical" ><Button     android:id="@+id/Button1"    android:layout_width="fill_parent"    android:layout_height="wrap_content"    android:text="开启发送通知栏"/><Button     android:id="@+id/Button2"    android:layout_width="fill_parent"    android:layout_height="wrap_content"    android:text="停止发送通知栏"/>   </LinearLayout>

activity2.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:orientation="vertical" ><TextView     android:id="@+id/text1"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:background="@drawable/setbar_bg"    /></LinearLayout>

主文件NotificationMainActivity.java

public class NotificationMainActivity extends Activity implements OnClickListener {private static Button button1,button2;private AllApplication application;public NotificationManager mNotificationManager;//定义count为通知内容用以测试public int count=0;    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_notification_main);       // 获取全局上下文对象        application=(AllApplication) getApplication();        button1=(Button)findViewById(R.id.Button1);        button1.setOnClickListener(this);        findViewById(R.id.Button2).setOnClickListener(this);                   }public void onClick(View v) {// TODO Auto-generated method stubswitch (v.getId()) {case R.id.Button1:count=0; /**创建一个可安排在给定延迟后运行命令或者定期地执行的线程池。 效果类似于Timer定时器         * ScheduledThreadPool是一个固定大小的线程池，与FixedThreadPool类似，执行的任务是定时执行。          *  */application.scheduledThreadPool = Executors.newScheduledThreadPool(1);//5秒后执行，以后每10秒执行一次application.scheduledThreadPool.scheduleWithFixedDelay(new CustomTask(), 5, 10,TimeUnit.SECONDS);break;case R.id.Button2:application.scheduledThreadPool.shutdown();application.scheduledThreadPool=null;//取消通知栏显示mNotificationManager.cancel(100);break;}}class CustomTask implements Runnable {public void run() {// TODO Auto-generated method stubBundle date=new Bundle();date.putInt("count", count++);Message message = Message.obtain(sHandler, 1);message.setData(date);message.sendToTarget();}}private Handler sHandler = new Handler() {@Overridepublic void handleMessage(Message msg) {// TODO Auto-generated method stubsuper.handleMessage(msg);switch (msg.what) {case 1:int counts=msg.getData().getInt("count");mNotificationManager= (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);//手机最上方提示栏的内容Notification notification = new Notification(R.drawable.ic_launcher,"count值发生变化当前为"+count, System.currentTimeMillis());/** * 设置添加声音 * 或者使用以下几种方式  * notification.sound = Uri.parse("file:///sdcard/notification/ringer.mp3");  * notification.sound = Uri.withAppendedPath(Audio.Media.INTERNAL_CONTENT_URI, "6");  * 如果想要让声音持续重复直到用户对通知做出反应，则可以在notification的flags字段增加"FLAG_INSISTENT"  * 如果notification的defaults字段包括了"DEFAULT_SOUND"属性，则这个属性将覆盖sound字段中定义的声音  * 还可以添加震动 notification.defaults |= Notification.DEFAULT_VIBRATE;  * 或者可以定义自己的振动模式：  * long[] vibrate = {0,100,200,300}; //0毫秒后开始振动，振动100毫秒后停止，再过200毫秒后再次振动300毫秒  * notification.vibrate = vibrate;  * */notification.defaults |= Notification.DEFAULT_SOUND;/** * notification.flags |= FLAG_AUTO_CANCEL; //在通知栏上点击此通知后自动清除此通知  * notification.flags |= FLAG_INSISTENT; //重复发出声音，直到用户响应此通知  */notification.flags = Notification.FLAG_AUTO_CANCEL;//通知栏的titleCharSequence contentTitle = "测试";//通知栏的内容CharSequence contentText="count值发生变化快去看看吧";//当点击通知栏时给其设置一个跳转的页面Intent notificationIntent = new Intent();notificationIntent.setClass(getApplicationContext(),Activity2.class);//在这里传值给点击跳转的IntentnotificationIntent.putExtra("count", counts);PendingIntent contentIntent = PendingIntent.getActivity(getApplicationContext(), 0, notificationIntent,PendingIntent.FLAG_UPDATE_CURRENT);//将上面的设置加入通知栏notification.setLatestEventInfo(getApplicationContext(),contentTitle, contentText, contentIntent);// 用mNotificationManager的notify方法通知用户生成标题栏消息通知//这里的ID100，用来定义状态栏通知以及下拉任务栏通知，并且用来在需要的时候，将这两样取消mNotificationManager.notify(100, notification);break;default:break;}}};@Overrideprotected void onDestroy() {// TODO Auto-generated method stubsuper.onDestroy();}}

点击跳转后的文件Activity2.java

public class Activity2 extends Activity{private AllApplication application;@Overrideprotected void onCreate(Bundle savedInstanceState) {// TODO Auto-generated method stubsuper.onCreate(savedInstanceState); application=(AllApplication) getApplication();application.scheduledThreadPool.shutdown(); application.scheduledThreadPool=null; setContentView(R.layout.activity2); Bundle bundle=getIntent().getExtras(); int count=bundle.getInt("count"); TextView textView=(TextView)findViewById(R.id.text1); textView.setText("当前count值为"+count);}}

好了，全部代码都在这里了。。。有不足的地方欢迎大家指正
