这篇文章主要讲解了Android 8.0实现发送通知的方法，内容清晰明了，对此有兴趣的小伙伴可以学习一下，相信大家阅读完之后会有帮助。

在Android8.0以后，针对Notification 通知api做了修改，新增了通知渠道(NotificationCannel)。下面就把demo的详细代码记录下：

1.Application 为NotificationManager添加通知频道

import android.app.Application;

import com.xinrui.ndkapp.notification.NotificationChannels;

public class NdkApplication extends Application {

@Override

public void onCreate() {

super.onCreate();

NotificationChannels.createAllNotificationChannels(this);

}

}

2.NotificationChannels 类

public class NotificationChannels {

public final static String CRITICAL = "critical";

public final static String IMPORTANCE = "importance";

public final static String DEFAULT = "default";

public final static String LOW = "low";

public final static String MEDIA = "media";

public static void createAllNotificationChannels(Context context) {

NotificationManager nm = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

if(nm == null) {

return;

}

NotificationChannel mediaChannel = new NotificationChannel(

MEDIA,

context.getString(R.string.app_name),

NotificationManager.IMPORTANCE_DEFAULT);

mediaChannel.setSound(null,null);

mediaChannel.setVibrationPattern(null);

nm.createNotificationChannels(Arrays.asList(

new NotificationChannel(

CRITICAL,

context.getString(R.string.app_name),

NotificationManager.IMPORTANCE_HIGH),

new NotificationChannel(

IMPORTANCE,

context.getString(R.string.app_name),

NotificationManager.IMPORTANCE_DEFAULT),

new NotificationChannel(

DEFAULT,

context.getString(R.string.app_name),

NotificationManager.IMPORTANCE_LOW),

new NotificationChannel(

LOW,

context.getString(R.string.app_name),

NotificationManager.IMPORTANCE_MIN),

//custom notification channel

mediaChannel

));

}

}

3.发送通知

public void sendSimpleNotification(Context context, NotificationManager nm) {

//创建点击通知时发送的广播

Intent intent = new Intent(context, NotificationMonitorService.class);

intent.setAction("android.service.notification.NotificationListenerService");

PendingIntent pi = PendingIntent.getService(context,0,intent,0);

//创建删除通知时发送的广播

Intent deleteIntent = new Intent(context,NotificationMonitorService.class);

deleteIntent.setAction(Intent.ACTION_DELETE);

PendingIntent deletePendingIntent = PendingIntent.getService(context,0,deleteIntent,0);

//创建通知

Notification.Builder nb = new Notification.Builder(context, NotificationChannels.DEFAULT)

//设置通知左侧的小图标

.setSmallIcon(R.drawable.ic_notification)

//设置通知标题

.setContentTitle("Simple notification")

//设置通知内容

.setContentText("Demo for simple notification!")

//设置点击通知后自动删除通知

.setAutoCancel(true)

//设置显示通知时间

.setShowWhen(true)

//设置通知右侧的大图标

.setLargeIcon(BitmapFactory.decodeResource(context.getResources(),R.drawable.ic_notifiation_big))

//设置点击通知时的响应事件

.setContentIntent(pi)

//设置删除通知时的响应事件

.setDeleteIntent(deletePendingIntent);

//发送通知

nm.notify(Notificaitons.NOTIFICATION_SAMPLE,nb.build());

}
