我们在用手机的时候,如果来了短信,而我们没有点击查看的话,是不是在手机的最上边的状态栏里有一个短信的小图标提示啊?你是不是也想实现这种功能呢?今天的Notification就是解决这个问题的。
我们也知道Android系统也是在不断升级的,有关Notification的用法也就有很多种,有的方法已经被android抛弃了,现在我实现了三种不同的方法,并适应不同的android版本。现在我就把代码公布出来,我喜欢把解释写在代码中,在这里我就不多说了,先看效果图:


package net.loonggg.notification;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.os.Bundle;import android.view.View;import android.widget.RemoteViews;public class MainActivity extends Activity {private static final int NOTIFICATION_FLAG = 1;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);}public void notificationMethod(View view) {// 在Android进行通知处理,首先需要重系统哪里获得通知管理器NotificationManager,它是一个系统Service。NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);switch (view.getId()) {// 默认通知case R.id.btn1:// 创建一个PendingIntent,和Intent类似,不同的是由于不是马上调用,需要在下拉状态条出发的activity,所以采用的是PendingIntent,即点击Notification跳转启动到哪个ActivityPendingIntent pendingIntent = PendingIntent.getActivity(this, 0,new Intent(this, MainActivity.class), 0);// 下面需兼容Android 2.x版本是的处理方式// Notification notify1 = new Notification(R.drawable.message,// "TickerText:" + "您有新短消息,请注意查收!", System.currentTimeMillis());Notification notify1 = new Notification();notify1.icon = R.drawable.message;notify1.tickerText = "TickerText:您有新短消息,请注意查收!";notify1.when = System.currentTimeMillis();notify1.setLatestEventInfo(this, "Notification Title","This is the notification message", pendingIntent);notify1.number = 1;notify1.flags |= Notification.FLAG_AUTO_CANCEL; // FLAG_AUTO_CANCEL表明当通知被用户点击时,通知将被清除。// 通过通知管理器来发起通知。如果id不同,则每click,在statu那里增加一个提示manager.notify(NOTIFICATION_FLAG, notify1);break;// 默认通知 API11及之后可用case R.id.btn2:PendingIntent pendingIntent2 = PendingIntent.getActivity(this, 0,new Intent(this, MainActivity.class), 0);// 通过Notification.Builder来创建通知,注意API Level// API11之后才支持Notification notify2 = new Notification.Builder(this).setSmallIcon(R.drawable.message) // 设置状态栏中的小图片,尺寸一般建议在24×24,这个图片同样也是在下拉状态栏中所显示,如果在那里需要更换更大的图片,可以使用setLargeIcon(Bitmap// icon).setTicker("TickerText:" + "您有新短消息,请注意查收!")// 设置在status// bar上显示的提示文字.setContentTitle("Notification Title")// 设置在下拉status// bar后Activity,本例子中的NotififyMessage的TextView中显示的标题.setContentText("This is the notification message")// TextView中显示的详细内容.setContentIntent(pendingIntent2) // 关联PendingIntent.setNumber(1) // 在TextView的右方显示的数字,可放大图片看,在最右侧。这个number同时也起到一个序列号的左右,如果多个触发多个通知(同一ID),可以指定显示哪一个。.getNotification(); // 需要注意build()是在API level// 16及之后增加的,在API11中可以使用getNotificatin()来代替notify2.flags |= Notification.FLAG_AUTO_CANCEL;manager.notify(NOTIFICATION_FLAG, notify2);break;// 默认通知 API16及之后可用case R.id.btn3:PendingIntent pendingIntent3 = PendingIntent.getActivity(this, 0,new Intent(this, MainActivity.class), 0);// 通过Notification.Builder来创建通知,注意API Level// API16之后才支持Notification notify3 = new Notification.Builder(this).setSmallIcon(R.drawable.message).setTicker("TickerText:" + "您有新短消息,请注意查收!").setContentTitle("Notification Title").setContentText("This is the notification message").setContentIntent(pendingIntent3).setNumber(1).build(); // 需要注意build()是在API// level16及之后增加的,API11可以使用getNotificatin()来替代notify3.flags |= Notification.FLAG_AUTO_CANCEL; // FLAG_AUTO_CANCEL表明当通知被用户点击时,通知将被清除。manager.notify(NOTIFICATION_FLAG, notify3);// 步骤4:通过通知管理器来发起通知。如果id不同,则每click,在status哪里增加一个提示break;// 自定义通知case R.id.btn4:// Notification myNotify = new Notification(R.drawable.message,// "自定义通知:您有新短信息了,请注意查收!", System.currentTimeMillis());Notification myNotify = new Notification();myNotify.icon = R.drawable.message;myNotify.tickerText = "TickerText:您有新短消息,请注意查收!";myNotify.when = System.currentTimeMillis();myNotify.flags = Notification.FLAG_NO_CLEAR;// 不能够自动清除RemoteViews rv = new RemoteViews(getPackageName(),R.layout.my_notification);rv.setTextViewText(R.id.text_content, "hello wrold!");myNotify.contentView = rv;Intent intent = new Intent(Intent.ACTION_MAIN);PendingIntent contentIntent = PendingIntent.getActivity(this, 1,intent, 1);myNotify.contentIntent = contentIntent;manager.notify(NOTIFICATION_FLAG, myNotify);break;case R.id.btn5:// 清除id为NOTIFICATION_FLAG的通知manager.cancel(NOTIFICATION_FLAG);// 清除所有的通知// manager.cancelAll();break;default:break;}}}
