没有调用Android OnNewIntent

Question

我看到了几种方法,我尝试了一切,但无法使它工作.我不知道为什么它如此复杂,在文档中它看起来如此简单!我想通过通知触发OnNewIntent(用户在通知栏中单击它).

目前我已将Activity设置为singleTop

<activity
    android:name="-.-.-.MainMenuActivity"
    android:launchMode="singleTop"
    android:screenOrientation="portrait" >
</activity>

这是我创建通知的代码:

public void showNotification(String text, String componentId){
    NotificationCompat.Builder mBuilder =
            new NotificationCompat.Builder(this)
            .setSmallIcon(R.drawable.logo)
            .setContentTitle("Title")   
            .setAutoCancel(true)
            .setContentText(text);

    // Creates an explicit intent for an Activity in your app
    Intent resultIntent = new Intent(this, MainMenuActivity.class);
    if(!componentId.equalsIgnoreCase("")){                         
        resultIntent.putExtra("componentId", componentId);
    }   
    resultIntent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_CLEAR_TOP);

    PendingIntent resultPendingIntent = PendingIntent.getActivity(this, 0, resultIntent, 0);
    mBuilder.setFullScreenIntent(resultPendingIntent, false);
    mBuilder.setContentIntent(resultPendingIntent);
    NotificationManager mNotificationManager =
        (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    // mId allows you to update the notification later on.
    mNotificationManager.notify(0, mBuilder.build());
}

这是我的MainMenuActivity中的OnNewIntent方法:

@Override
protected void onNewIntent(Intent intent) {
    // TODO Auto-generated method stub
    super.onNewIntent(intent);
    setIntent(intent);

    ...
}

我从未接到过OnNewIntent电话.我不知道我做错了什么.我在整个应用程序中只使用了2个活动,并且MainMenuActivity位于LoginActivity之后,因此MainMenuActivity应始终位于堆栈顶部(我有更多的片段,我在MainMenuActivity中替换它们).

任何帮助,将不胜感激!感谢你们.

好的,在发布我的问题之后很快就开始了.我认为代码中的关键区别在于我将标志"PendingIntent.FLAG_UPDATE_CURRENT"传递给PendingIntent对象的创建/检索.这篇文章帮我弄明白了.

Notification.Builder mBuilder =
                new Notification.Builder(context)
                .setSmallIcon(R.drawable.notifyicon)
                .setContentTitle(title)
                .setContentText(extras.getString("message"))
                .setAutoCancel(true)
                .setOnlyAlertOnce(false)
                .setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
                .setVibrate(new long[] {0,500,250,500});

        if(badgeCount > 1)
            mBuilder.setNumber(badgeCount);
        // Creates an explicit intent for an Activity in your app
        Intent resultIntent = new Intent(context, SiteViewActivity.class);
        resultIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
        resultIntent.putExtra(NOTIFY_INTENT_TYPE_KEY, alertType);

        PendingIntent resultPendingIntent = PendingIntent.getActivity(context, alertType, resultIntent, PendingIntent.FLAG_UPDATE_CURRENT);
        mBuilder.setContentIntent(resultPendingIntent);
        NotificationManager notifyMgr = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
        notifyMgr.notify(alertType, mBuilder.build());

首先,您应该android:launchMode="singleTop"在清单文件中添加您的活动定义,如下所示

<activity
    android:name="MainActivity"
    android:launchMode="singleTop"
</activity>

然后,像哈桑马苏德说,你应该添加Intent.ACTION_MAIN和Intent.CATEGORY_LAUNCHER你的动作像如下

Intent intent = new Intent(this, MainActivity.class);
intent.setAction(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_LAUNCHER);

就这样.通过这种方式,如果应用程序处于打开状态,当您单击通知时,onNewIntent(..)方法将触发,但无论发生什么,如果应用程序关闭,当您单击通知时,通知意图将转到onCreate(.. )当前活动的方法.
