使用替換時FragmentManager崩潰

我有一個活動和幾個片段。我必須在FrameLayout中替換片段。但是，當我使用這個功能我的應用程序崩潰。這裏是功能使用替換時FragmentManager崩潰

Android.Support.V4.App.Fragment fragment = null; 
     switch (position) { 
     case 0: 
      fragment = new ScheduleFragment(); 
      break; 
     case 1: 
      fragment = new MainFragment(); 
      break; 
     } 
     if (fragment != null) { 

      Android.Support.V4.App.FragmentManager fragmentManager = SupportFragmentManager; 
      var transaction = fragmentManager.BeginTransaction(); 
      transaction.Replace(Resource.Id.content_frame, fragment); 
      transaction.Commit(); 

      mDrawerList.SetItemChecked (position, true); 
      SetTitle (mScreenTitles [position]); 
      mDrawerLayout.CloseDrawer (mDrawerList); 
     } else { 
      Log.Error (this.Class.Name, "Error, fragment not created"); 
     }

的代碼，這裏是一個錯誤：

佈局。

<?xml version="1.0" encoding="utf-8"?> 
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/drawer_layout" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:background="@drawable/gradientshape"> 
    <LinearLayout 
     android:orientation="vertical" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent">

      android:layout_height="wrap_content" 
      android:id="@+id/info"

     <TextView

</android.support.v4.widget.DrawerLayout>

另外我加載片段的片段佈局在viewPager中。這是它：

<ListView 
    android:minWidth="25px" 
    android:minHeight="25px" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:id="@+id/LessonsView" 
    android:layout_marginLeft="5dp" 
    android:padding="15dp" 
    android:divider="@null" 
    android:dividerHeight="0dp" 
    android:layout_marginTop="5dp" 
    android:layout_marginRight="5dp" 
    android:layout_marginBottom="5dp" />

請問您能否包含佈局xml代碼？ – matthewrdev

@MattR，添加viewPager適配器，viewPager片段，列表視圖中項目的主佈局和佈局，這是viewpager的片段 – AsTex

我不能肯定在此基礎上snipit，但如果你試圖訪問一個Android資源ID如前面提到的人，你需要在Xamarin使用Android.Resource.Id。

如果這不是你想要的，我會問你是否在你想要的容器中有一個FrameLayout，其ID爲content_frame。

我設計了我的佈局，幷包含一個FrameLayout，這是我使用SupportFragmentManager切入和切出的。

Android.Support.V4.App.Fragment fragment = null; 
    switch (position) { 
    case 0: 
     fragment = new ScheduleFragment(); 
     break; 
    case 1: 
     fragment = new MainFragment(); 
     break; 
    } 
    if (fragment != null) { 

     Android.Support.V4.App.FragmentManager fragmentManager = SupportFragmentManager; 
     var transaction = fragmentManager.BeginTransaction(); 
     // ---- change this line ---- // 
     transaction.Replace(R.id.content_frame, fragment); 
     transaction.Commit(); 

     mDrawerList.SetItemChecked (position, true); 
     SetTitle (mScreenTitles [position]); 
     mDrawerLayout.CloseDrawer (mDrawerList); 
    } else { 
     Log.Error (this.Class.Name, "Error, fragment not created"); 
    }

您的意思是Resource.Id.content_frame？我使用Xamarin.Android。 Resource.id == R.id – AsTex

向下投票，因爲它不清楚該修復程序是什麼。你能補充一些進一步的解釋嗎？ – matthewrdev
