PendingIntent不会发送意图演员 [英] PendingIntent does not send Intent extras

问题描述

我的 MainActicity 启动 RefreshService 与意图这有一个布尔额外名为 isNextWeek 。

我的 RefreshService 使通知这将启动我的 MainActivity

这看起来是这样的：

  Log.d（刷新，RefreshService有：isNextWeek：+将String.valueOf（isNextWeek））;

    意图notificationIntent =新的意图（这一点，MainActivity.class）;
    notificationIntent.putExtra（MainActivity.IS_NEXT_WEEK，isNextWeek）;

    Log.d（刷新，RefreshService放在意图：isNextWeek：+将String.valueOf（notificationIntent.getBooleanExtra（MainActivity.IS_NEXT_WEEK，FALSE）））;
    pendingIntent = PendingIntent.getActivity（此，0，notificationIntent，0）;

    建设者=新NotificationCompat.Builder(this).setContentTitle("Title").setContentText("ContentText").setSmallIcon(R.drawable.ic_notification).setContentIntent(pendingIntent);
    通知= builder.build（）;
    //隐藏其选中后通知
    notification.flags | = Notification.FLAG_AUTO_CANCEL;
    notificationManager.notify（NOTIFICATION_REFRESH，通知）;
 

正如你可以看到 notificationIntent 应具备的布尔额外 IS_NEXT_WEEK 与 isNextWeek 的值被放在 PendingIntent 。

当我点击此通知我总是假作为价值 isNextWeek

这是我得到的价值的方式 MainActivity ：

isNextWeek = getIntent（）getBooleanExtra（IS_NEXT_WEEK，假）。

日志：

  08-04 00：19：32.500 13367-13367 / de.MayerhoferSimon.Vertretungsplan D /刷新：MainActivity发送：isNextWeek：真
08-04 00：19：32.510 13367-13573 / de.MayerhoferSimon.Vertretungsplan D /刷新：RefreshService有：isNextWeek：真
08-04 00：19：32.510 13367-13573 / de.MayerhoferSimon.Vertretungsplan D /刷新：RefreshService放在意图：isNextWeek：真
08-04 00：19：41.990 13367-13367 / de.MayerhoferSimon.Vertretungsplan D /刷新：MainActivity.onCreate有：isNextWeek：假的
 

当我直接启动 MainActivity 与意图与ìsNextValue`是这样的：

 意向书我=新的意图（这一点，MainActivity.class）;
    i.putExtra（IS_NEXT_WEEK，isNextWeek）;
    完（）;
    startActivity（ⅰ）;
 

一切工作正常，我也得到真在 isNextWeek 是真。

做什么我做了错误总是有一个假值？

报价：的

  

我的怀疑是，因为唯一改变的意图是   临时演员，在 PendingIntent.getActivity（...）工厂方法是   简单地重新使用旧的意图作为优化。

     

在RefreshService，请尝试：

  PendingIntent pendingIntent = PendingIntent.getActivity（此，0，notificationIntent，PendingIntent.FLAG_CANCEL_CURRENT）;

解决方案

我认为你需要更新意图当你收到一个新的通过覆盖 onNewIntent（意向），在活动。以下添加到您的活动：

  @覆盖
公共无效onNewIntent（意向newIntent）{
    this.setIntent（newIntent）;

    //现在getIntent（）返回更新意向
    isNextWeek = getIntent（）getBooleanExtra（IS_NEXT_WEEK，假）。
}
 

编辑：

这是只需要如果你的活动已经开始收到的意图时。如果你的活动开始（而不仅仅是恢复）的意图，那么问题是在其他地方，我的建议可能不会解决这个问题。

My MainActicity starts RefreshService with a Intent which has a boolean extra called isNextWeek.

My RefreshService makes a Notification which starts my MainActivity when the user clicks on it.

this looks like this:

    Log.d("Refresh", "RefreshService got: isNextWeek: " + String.valueOf(isNextWeek));

    Intent notificationIntent = new Intent(this, MainActivity.class);
    notificationIntent.putExtra(MainActivity.IS_NEXT_WEEK, isNextWeek);

    Log.d("Refresh", "RefreshService put in Intent: isNextWeek: " + String.valueOf(notificationIntent.getBooleanExtra(MainActivity.IS_NEXT_WEEK,false)));
    pendingIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);

    builder = new NotificationCompat.Builder(this).setContentTitle("Title").setContentText("ContentText").setSmallIcon(R.drawable.ic_notification).setContentIntent(pendingIntent);
    notification = builder.build();
    // Hide the notification after its selected
    notification.flags |= Notification.FLAG_AUTO_CANCEL;
    notificationManager.notify(NOTIFICATION_REFRESH, notification);

As you can see the notificationIntent should have the booleanextra IS_NEXT_WEEK with the value of isNextWeek which is put in the PendingIntent.

When I click now this Notification I always get false as value of isNextWeek

This is the way I get the value in the MainActivity:

    isNextWeek = getIntent().getBooleanExtra(IS_NEXT_WEEK, false);

Log:

08-04 00:19:32.500  13367-13367/de.MayerhoferSimon.Vertretungsplan D/Refresh: MainActivity sent: isNextWeek: true
08-04 00:19:32.510  13367-13573/de.MayerhoferSimon.Vertretungsplan D/Refresh: RefreshService got: isNextWeek: true
08-04 00:19:32.510  13367-13573/de.MayerhoferSimon.Vertretungsplan D/Refresh: RefreshService put in Intent: isNextWeek: true
08-04 00:19:41.990  13367-13367/de.MayerhoferSimon.Vertretungsplan D/Refresh: MainActivity.onCreate got: isNextWeek: false

When I directly start the MainActivity with an Intent with the ìsNextValue` like this:

    Intent i = new Intent(this, MainActivity.class);
    i.putExtra(IS_NEXT_WEEK, isNextWeek);
    finish();
    startActivity(i);

everything works fine and I get true when isNextWeek is true.

What do I make wrong that there is always a false value?

UPDATE

Quote:

My suspicion is that, since the only thing changing in the Intent is the extras, the PendingIntent.getActivity(...) factory method is simply re-using the old intent as an optimization.

In RefreshService, try:

PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, notificationIntent, PendingIntent.FLAG_CANCEL_CURRENT);

See:

http://developer.android.com/reference/android/app/PendingIntent.html#FLAG_CANCEL_CURRENT

解决方案

I think you need to update the Intent when you receive a new one by overriding onNewIntent(Intent) in your Activity. Add the following to your Activity:

@Override
public void onNewIntent(Intent newIntent) {
    this.setIntent(newIntent);

    // Now getIntent() returns the updated Intent
    isNextWeek = getIntent().getBooleanExtra(IS_NEXT_WEEK, false);        
}

Edit:

This is needed only if your Activity has already been started when the intent is received. If your activity is started (and not just resumed) by the intent, then the problem is elsewhere and my suggestion may not fix it.
