android - 果冻 bean 通知操作已禁用

Question

我正在构建一个应用程序，它在调用 BroadcastReceiver 时显示带有两个选项“Dim”和“Full”的通知。每个按钮都会广播一个 Action 。

到目前为止，一切皆有可能，对吗？

问题是通知上显示的按钮不响应点击但整个通知响应(如果我单击图标或文本而不是按钮)。

我有这个功能来构建通知:

private Notification buildReleaseNotification(NotificationManager nManager, Context context) {

    Notification.Builder builder = new Builder(context);
    builder.addAction(R.drawable.rate_star_big_half_holo_dark, "Dim", buildPendingIntent(context, DIM));
    builder.addAction(R.drawable.rate_star_big_on_holo_dark, "Full", buildPendingIntent(context, FULL));

    builder.setContentTitle("Car notification");
    builder.setContentText("Freed");
    builder.setSmallIcon(R.drawable.ic_launcher);
    builder.setOngoing(true);

    Notification notification = builder.build();
    return notification;
}

接收广播时调用:

    public void onReceive(Context context, Intent intent) {

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

    Notification noty = null;
    noty = buildReleaseNotification(context);
    startService(context, RELEASE);

    if (noty != null) {
        nManager.notify(ChangeLockService.GLOBAL_TAG, ID, noty);
    }

}

------ 编辑

刚刚注意到以下函数返回 null...那么，我如何构建一个待处理的 Intent 来执行广播？

private PendingIntent buildPendingIntent(Context context, String action) {

        Intent i = new Intent(action);
        PendingIntent pi = PendingIntent.getBroadcast(context, ID, i, Intent.FLAG_RECEIVER_REPLACE_PENDING);
        return pi;
    }

Answer 1

创建 Intent 时通过

PendingIntent pi = PendingIntent.getBroadcast(context, ID, i, Intent.FLAG_RECEIVER_REPLACE_PENDING);

导致它返回 null。根据文档，我了解到标志 Intent.FLAG_RECEIVER_REPLACE_PENDING 将替换该按钮已经存在的任何未决 Intent 。如果我不发送标志，那么一切正常:

PendingIntent pi = PendingIntent.getBroadcast(context, ID, i, 0);
