如何在导航抽屉项目中使用片段从片段中调用片段

Question

我有一个带有多个片段的Navigation Drawer项目。在一种情况下，我需要从另一个片段中调用一个片段。但是我收到下面的错误。

  

E / Android运行时：致命异常：主要       流程：pe.soltec.yupay17，PID：4404       java.lang.RuntimeException：pe.soltec.yupay17.MainActivity@acf9ed30必须实现OnFragmentInteractionListener           在pe.soltec.yupay17.PinkFragment.onAttach（PinkFragment.java:83）           在android.support.v4.app.FragmentManagerImpl.moveToState（FragmentManager.java:1404）           在android.support.v4.app.FragmentTransition.addToFirstInLastOut（FragmentTransition.java:1195）          在android.support.v4.app.FragmentTransition.calculateFragments（FragmentTransition.java:1078）          在android.support.v4.app.FragmentTransition.startTransitions（FragmentTransition.java:117）          在android.support.v4.app.FragmentManagerImpl.executeOpsTogether（FragmentManager.java:2408）          在android.support.v4.app.FragmentManagerImpl.removeRedundantOperationsAndExecute（FragmentManager.java:2366）          在android.support.v4.app.FragmentManagerImpl.execPendingActions（FragmentManager.java:2273）           在android.support.v4.app.FragmentManagerImpl $ 1.run（FragmentManager.java:733）           在android.os.Handler.handleCallback（Handler.java:733）           在android.os.Handler.dispatchMessage（Handler.java:95）           在android.os.Looper.loop（Looper.java:136）           在android.app.ActivityThread.main（ActivityThread.java:5017）           在java.lang.reflect.Method.invokeNative（本机方法）           在java.lang.reflect.Method.invoke（Method.java:515）           在com.android.internal.os.ZygoteInit $ MethodAndArgsCaller.run（ZygoteInit.java:779）           在com.android.internal.os.ZygoteInit.main（ZygoteInit.java:595）           在dalvik.system.NativeStart.main（本机方法）

我试图像在主要活动中调用片段一样来调用它。

getSupportFragmentManager().beginTransaction().replace(R.id.content_main,miFragment).commit();

我想在content_main中显示新片段。
