【学习笔记】Android5.X Notification新功能初识

• 基本的Notification
  
  

  /**
       * 基本的Notification
       */
      private void notificationBasic(){
          Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.baidu.com"));
          //构造pendingIntent
          PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, 0);
          //创建Notification对象
          Notification.Builder builder = new Notification.Builder(this);
          //设置Notification的各种属性
          builder.setSmallIcon(R.mipmap.ic_launcher);
          builder.setContentIntent(pendingIntent);
          builder.setAutoCancel(true);
          builder.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher));
          builder.setContentTitle("Basic Notification");
          builder.setContentText("这是一个基本通知");
          builder.setSubText("副标题");
          //通过NotificationManager来发出Notification
          NotificationManager notificationManager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
          notificationManager.notify(NOTIFICATION_ID_BASIC, builder.build());
      }

  
  

  
  

  效果：
  
  
  
  
• 折叠式的Notification
  
  

  /**
       * 折叠式的Notification
       */
      private void notificationCollapsed(){
          Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.baidu.com"));
          //构造pendingIntent
          PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, 0);
          //创建Notification对象
          Notification.Builder builder = new Notification.Builder(this);
          //设置Notification的各种属性
          builder.setSmallIcon(R.mipmap.ic_launcher);
          builder.setContentIntent(pendingIntent);
          builder.setAutoCancel(true);
          builder.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher));
  
          //通过RemoteViews来创建自定义的Notification视图
          RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.notification);
          contentView.setTextViewText(R.id.textView, "show me whe collapsed");
  
          Notification notification = builder.build();
          notification.contentView = contentView;
  
          //通过RemoteViews来创建自定义的Notification视图
          RemoteViews expandedView = new RemoteViews(getPackageName(), R.layout.notification_expanded);
          notification.bigContentView = expandedView;
  
          NotificationManager nm = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
          nm.notify(NOTIFICATION_ID_COLLAPSE, notification);
      }

  
  

  
  

  
  
  
  
  
• 悬挂式的Notification
  
  

  /**
       * 悬挂式的Notification
       */
      private void notificationHeadSup(){
          Notification.Builder builder = new Notification.Builder(this)
                  .setSmallIcon(R.mipmap.ic_launcher)
                  .setPriority(Notification.PRIORITY_DEFAULT)
                  .setCategory(Notification.CATEGORY_MESSAGE)
                  .setContentTitle("悬挂式通知")
                  .setContentText("这是一个悬挂式通知");
  
          Intent push = new Intent();
          push.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
          push.setClass(this, NotificationActivity.class);
          PendingIntent pi = PendingIntent.getActivity(this, 0, push, PendingIntent.FLAG_CANCEL_CURRENT);
          builder.setContentText("android5.0悬挂式通知")
                  .setFullScreenIntent(pi, true);
  
          NotificationManager nm = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
          nm.notify(NOTIFICATION_ID_HEADSUP, builder.build());
      }

  
  

  
  

  
  
  
• 显示等级的Notification
  
  

  /**
       * 显示等级的Notification
       * Android 5.X将Notification分成了三个等级
       * VISIBILITY_PRIVATE 表示只有当没有锁屏的时候会显示
       * VISIBILITY_PUBLIC 表示在任何情况下都会显示
       * VISIBILITY_SECRET 表明在pin、password等安全锁和没有锁屏的情况下才能够显示
       */
      private void notificationVisibility(){
          Notification.Builder builder = new Notification.Builder(this)
                  .setContentTitle("Notification for Visibility Test")
                  .setColor(getResources().getColor(R.color.colorAccent));
          switch (rgVisibility.getCheckedRadioButtonId()){
              case R.id.rdo_private:
                  builder.setVisibility(Notification.VISIBILITY_PRIVATE);
                  builder.setContentText("Private");
                  builder.setSmallIcon(R.mipmap.ic_private);
                  break;
              case R.id.rdo_public:
                  builder.setVisibility(Notification.VISIBILITY_PUBLIC);
                  builder.setContentText("Public");
                  builder.setSmallIcon(R.mipmap.ic_public);
                  break;
              case R.id.rdo_secret:
                  builder.setVisibility(Notification.VISIBILITY_SECRET);
                  builder.setContentText("Secret");
                  builder.setSmallIcon(R.mipmap.ic_secret);
                  break;
          }
          NotificationManager nm = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
          nm.notify(NOTIFICATION_ID_VISIBILITY, builder.build());
      }
