導航抽屜錯誤

Question

我的應用程序出現問題。 程序說：

"error: no suitable method found for replace(int,android.app.Fragment) 
method FragmentTransaction.replace(int,android.support.v4.app.Fragment,String) is not applicable 
(actual and formal argument lists differ in length) 
method FragmentTransaction.replace(int,android.support.v4.app.Fragment) is not applicable 
(actual argument android.app.Fragment cannot be converted to android.support.v4.app.Fragment by method invocation conversion)" 

我不知道我能用它做什麼。

Answer 1

看起來你已經在類中導入了錯誤類型的片段。你需要導入android.support.v4.app.Fragment而不是android.app.Fragment
