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：

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
