导航抽屉错误

Question

我的应用有问题。 计划说：

"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些什么。

Answer 1

看起来你在类中导入了错误类型的Fragment。您需要导入android.support.v4.app.Fragment而不是android.app.Fragment
