在自定义DialogFragment中没有找到ID为片段的视图

我知道这里有很多类似的问题，但是我没有找到任何修复我的问题的人，所以我们走了。在自定义DialogFragment中没有找到ID为片段的视图

在一个活动我有这样的代码：

TMTutorial tutorial = new TMTutorial(); 
tutorial.show(getSupportFragmentManager(), "blalba");

TMTutorial看起来是这样的：

import android.os.Bundle; 
import android.support.v4.app.DialogFragment; 
import android.support.v4.app.Fragment; 
import android.support.v4.app.FragmentManager; 
import android.support.v4.app.FragmentPagerAdapter; 
import android.support.v4.view.ViewPager; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 

import tm.mello.se.R; 
import tm.mello.se.TMWelcomeFragment; 

public class TMTutorial extends DialogFragment{ 
View mRootView; 
LayoutInflater mInflater; 

public TMTutorial() { 

} 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) 
{ 
    mRootView = inflater.inflate(R.layout.tutorial_layout, container); 
    mInflater = inflater; 

    setupViewPager(); 

    return mRootView; 
} 

private void setupViewPager() 
{ 
    ViewPager viewPager = (ViewPager) mRootView.findViewById(R.id.tutorial_pager); 

    viewPager.setAdapter(new Test(getFragmentManager())); 

    //viewPager.setAdapter(new Test(getFragmentManager())); 
} 


public class Test extends FragmentPagerAdapter 
{ 

    public Test(FragmentManager fm) 
    { 
     super(fm); 
    } 

    @Override 
    public Fragment getItem(int i) 
    { 
     return new TMWelcomeFragment(); 
    } 

    @Override 
    public int getCount() 
    { 
     return 3; 
    } 
} 
}

tutorial_layout.xml这样的：

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent"> 

<android.support.v4.view.ViewPager 
       android:layout_width="match_parent" 
       android:layout_height="match_parent" 
       android:id="@+id/tutorial_pager"/> 

</FrameLayout>

而且我得到这个堆栈跟踪：

FATAL EXCEPTION: main 
java.lang.IllegalArgumentException: No view found for id 0x7f05009d (xx.xxxx.xx:id/tutorial_pager) for fragment TMWelcomeFragment{42050698 #1 id=0x7f05009d android:switcher:2131034269:0}

任何人都知道问题是什么？：现在TMTutorial

Fragment fragment = TMTutorial.newInstance(); 
fragment.show(getSupportFragmentManager(), "blabla");

在活动试试这个

static TMTutorial newInstance() { 
    TMTutorial tutorial = new TMTutorial(); 
    return tutorial; 
}

没有，这将是片段和TMTutorial之间不兼容的类型，它没有工作 – Tobbbe

有链接片段的生命周期：http://developer.android.com/images/fragment_lifecycle.png后onCreateView完成onActivityCreated方法将被触发。在onActivityCreated中，您可以像下面这样获取viewPager： getView（）。findViewByIdR.id.tutorial_pager）; 而且你也不需要换一个新的视图。你可以返回容器。

没有工作，仍然同样的错误。 – Tobbbe

它的工作原理是如果我使用我的mRootView变量而不是getView（）方法。然而，对话框是空的：/只是一个没有任何东西的黑色方块...... – Tobbbe

您需要使用的

viewPager.setAdapter(new Test(getChildFragmentManager()))

代替

getSupportFragmentManager()
