从状态栏中的扩展通知中获取文本？

Question

是否可以在扩展通知中获取文本statusbar？这意味着文字设置了我Notification.BitTextStyle.bigText(),例如来自Gmail的电子邮件通知.

我想使用Notification.extras来获取它,但似乎没有常量,Notification.EXTRA_BIG_TEXT例如,允许它工作.

是否有另一种获取此文本的方法？当我使用时

String bigTitle = mExtras.getString(Notification.EXTRA_TITLE_BIG;

它回来了null,任何想法为什么？我用它来获取电子邮件的主题(Testing the new Gmail notification shortcuts- >见下面的链接).

以下是扩展Gmail通知的示例:(我想获得以下文字 - >

您现在可以获得回复和存档的快捷按钮...

Gmail通知的图片 (无法发布信誉低于10的图片,抱歉)

作为替代方案,我也尝试了以下方法:

RemoteViews rv = mNotification.contentView;
LayoutInflater inflater =   (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
ViewGroup localView = (ViewGroup) inflater.inflate(rv.getLayoutId(), null);
rv.reapply(getApplicationContext(), localView);
everything = new StringBuilder(150);

      for(int i=0; i<((ViewGroup)localView).getChildCount(); ++i) {
            View nextChild = ((ViewGroup)localView).getChildAt(i);
            try{
                TextView tv = (TextView) localView.findViewById(nextChild.getId());
                everything.append(tv.getText().toString());
            }catch(Exception e){
                continue;
            }
      }
Log.i("abc", everything.toString());

但这对我来说也不起作用,似乎从来没有从任何观点中得到任何文本.

更新:

当我使用以下代码从通知中获取文本时...:

body = mExtras.getString(Notification.EXTRA_TEXT);

...只要不是Gmail /电子邮件通知,一切正常:

收到Gmail通知后,我收到以下错误消息:

如果我然后通过将其更改为此来尝试解决该问题...

body = mExtras.getString(Notification.EXTRA_TEXT).toString();

......我得到了 NullPointerException

如果有人能帮助我,我真的很感激

谢谢,REG1

好的,有了这个新信息,我会尝试这样的事情:

SpannableString bigText = (SpannableString) mExtras.get(Notification.EXTRA_TEXT);
if(bigText != null){
    body = bigText.toString();
}

编辑:在查看源代码后,我会尝试这样做:

CharSequence bigText = (CharSequence) mExtras.getCharSequence(Notification.EXTRA_TEXT);
if(bigText != null){
    body = bigText.toString();
}
