Question

我在下面的代码配置生成通知：

Intent intent = new Intent(this, HomeActivity.class);
          intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK|Intent.FLAG_ACTIVITY_CLEAR_TOP);


        intent.putExtra("IsNotification",true);

        int mNotificationId= Pref.getValue(this, Constants.NOTIFICATION_ID,1);
        PendingIntent pendingIntent = PendingIntent.getActivity(this,mNotificationId /* Request code */, intent,
                PendingIntent.FLAG_UPDATE_CURRENT);

        Bitmap mBitmap= BitmapFactory.decodeResource(getResources(),R.mipmap.ic_launcher);

        Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.mipmap.ic_launcher).setLargeIcon(mBitmap)
                .setContentTitle("App Notification").setColor(getResources().getColor(R.color.orange))
                .setContentText(message)
                .setAutoCancel(true)
                .setSound(defaultSoundUri)
                .setContentIntent(pendingIntent);

        NotificationManager notificationManager =
                (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

        notificationManager.notify(mNotificationId /* ID of notification */, notificationBuilder.build());

        mNotificationId++;

        Pref.setValue(this,Constants.NOTIFICATION_ID,mNotificationId);

现在在Manifest中我有

<activity
            android:name=".HomeActivity"
            android:label="@string/title_activity_home"
            android:screenOrientation="portrait"
            android:windowSoftInputMode="adjustPan"
            android:launchMode="singleTop"
            />

现在我在OnCreate和onNewIntent，我正在检查它的捆绑包是否有一些通知值

如下所示代码来自OnCreate或onNewIntent的提交片段取决于活动实例：

private void initNotification(){

        if(mNotitficationFragment==null){

            mNotitficationFragment= NotitficationFragment.newInstance();
        }

        if(!mNotitficationFragment.isAdded()){

            mFragManager.beginTransaction().replace(R.id.frame_home_container,mNotitficationFragment).commit();

        }



    }

所以现在我的问题是NotificationFragment的onCreateView称它为`getActivity（）为null。

注意

对于片段，我使用support-v4:23.1.1作为片段。

尝试在onActivityCreated或onAttach之后或之后进行相关处理。对于onAttach已弃用的警告，请查看此answer。

从Notification中获取Home Activity时，在getment中将getActivity视为null
