因此，我正在編寫一個android應用程序，在單擊通知後啓動一個活動。我在我的logcat得到這個：由二元XML文件引起的佈局膨脹錯誤

我已經走遍StackOverflow的答案，因爲它似乎其他人也有類似的問題 - 我試圖重建和清潔項目，並重新啓動ADT以及創建一個新文件。我想知道這裏有沒有人有指導。
這是我的佈局文件：

另外這裏是SMSViewActivity代碼：

});
return v;
}
public void backToList() {

startActivity(i);
}
}
奇怪之處是，該異常被命名ActionBarOverlayLayout控件這是不是在我的佈局。如果有人知道這會有很大的幫助！ （週一到期的項目！） 克勞迪婭
u能在com.example.chowpalv21.SmsViewActivity.onCreateView（SmsViewActivity.java:121）粘貼在這裏的代碼 – Nazgul
'SmsViewActivity.java：80'這是80號線 – vjdhama
所有粘貼！謝謝！ – CoderClouds
