    NotificationCompat.Builder mBuilder =
            new NotificationCompat.Builder(this)
                    .setSmallIcon(R.mipmap.ic_launcher)
                    .setContentTitle("My notification")
                    .setContentText("Hello World!");

    // 2. 创建点击回调动作
    Intent resultIntent = new Intent(this, ResultActivity.class);
    // Because clicking the notification opens a new ("special") activity, there's
    // no need to create an artificial back stack.
    PendingIntent resultPendingIntent =
            PendingIntent.getActivity(
                    this,
                    0,
                    resultIntent,
                    PendingIntent.FLAG_UPDATE_CURRENT
            );
    mBuilder.setContentIntent(resultPendingIntent);

    // Builds the notification and issues it.
    mNotifyMgr.notify(101, mBuilder.build());

    // Sets the Activity to start in a new, empty task
    resultIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK |
            Intent.FLAG_ACTIVITY_CLEAR_TASK);
    // Creates the PendingIntent
    notifyIntent = PendingIntent.getActivity(
            this,
            0,
            resultIntent,
            PendingIntent.FLAG_UPDATE_CURRENT
    );

移除Notification

  1. 调用后自动清除
    abnf
    1
    builder.setAutoCancel(true);
  2. 指定的 notification ID调用了cancel()
  3. 指定的 notification ID调用了cancelAll()

接下来的几个样式就不说了，简单，先贴图再看代码

BigView之Text

  • 调用bigTextNotification

BigView之Picture

  • 调用bigPictureNotification

BigView之Inbox

  • 调用bigInboxNotification

BigView之Custom

  • 调用customNotification
    • 大图
    • 小图
