錯誤膨脹類的片段，inflateexception

-7

我有錯誤的東西，它的書面形式像android視圖膨脹異常錯誤在膨脹類的片段，它指向MainActivity.java類，我試圖找到但仍然沒有運氣，因爲沒有錯誤在android studio中，但在虛擬設備中運行時顯示錯誤。錯誤膨脹類的片段，inflateexception

我有錯誤的東西書面就像在Android設備上查看充氣異常錯誤膨脹類片段並將其指向MainActivity.java類，我試圖找到，但仍然沒有運氣，因爲在android studio中沒有錯誤，但在虛擬設備中運行時顯示錯誤。

show logcat please –

首先，你不是在'FragmentA'的'onCreateView（）'中返回佈局。但是，我們需要看到完整的堆棧跟蹤，以確定當前的問題。 –

試試這種方式。您的控制結合爲片段oncreatview方法內部的

@Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 

     View view = inflater.inflate(R.layout.change_pass_frag, container); 

     regmail=(EditText)view.findViewById(R.id.regemail); 
     oldpass=(EditText)view.findViewById(R.id.oldpass); 


     return view; 
    }

我得到它，我必須膨脹fragment_a 視圖視圖= inflater.inflate（R.layout.fragment_a，容器，FALSE）;
