Android 包含tabhost和viewpager的片段不'；不要重叠列表片段

我不知道如何解决这个错误我被困了3天帮我解决。我没有得到任何可以记录和显示的错误，这已经变得不可能了

MyListFragment.java this extends ListFragment and onListItemClick() I need to migrate to another two Fragments which should be displayed over this ListFragment.

public void onListItemClick（列表视图l、视图v、整数位置、长id）{
Log.d（“单击列表”、“单击是”）；
//字符串clickedDetail=（字符串）l.getItemAtPosition（位置）；
/*
*第二个片段尚未加载。
*按FragmentTransaction加载MyDetailFragment，并传递
*数据通过束从当前片段传输到第二个片段。
*/
MyDetailFragment MyDetailFragment=新的MyDetailFragment（）；
Bundle=新Bundle（）；
//bundle.putString（“关键字详细信息”，单击详细信息）；
myDetailFragment.setArguments（bundle）；
Log.d（“ListCLicked1”、“单击是”）；
碎片事务碎片事务=
getChildFragmentManager（）.beginTransaction（）；
Log.d（“ListCLicked2”，“Yes Clicked”）；
fragmentTransaction.add（R.id.tablistfragment，new MyDetailFragment（））；
Log.d（“ListCLicked3”，“Yes Clicked”）；
fragmentTransaction.commit（）；
}
MyDetailFragment.java是一个膨胀为detailfragment.xml的片段，包含两个要重叠在MyListFragment上的片段。MyListFragment包含加载程序，它记录我的电话簿联系人，并在单击任何列表项时从中形成一个列表，我需要获取包含联系人详细信息的片段。帮助！！！！！！！！！

MyDetailFragment.java is Fragment that an inflate to detailfragment.xml containg two fragments to be overlapped over the MyListFragment.

MyDetailActivity extends FragmentActivity initialising the Tabhost and Viewpager.This activity doesn't get called when I execute even gives no error.I execute ContactHistory which inflates tablayout.xml , where I specify tools:context=".MyDetailACtivity"

                startActivity(emailIntent);



        }


}

ContactHistory.java ContactHistory just gives an inflate call to the tablayout and finds the ids for the tabhost and viewpagers.



import android.os.Bundle;
import android.os.StrictMode;
import android.support.v4.app.Fragment;
import android.support.v4.view.ViewPager;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TabHost;

public class ContactHistory extends Fragment {

    View view;
    public TabsPagerAdapter mAdapter;
    public ViewPager mViewPager;
    public TabHost mTabHost;

    public View onCreateView(LayoutInflater inflator,ViewGroup container,Bundle saveInstanceState)
    {
        Log.d("ContactHistory","History Oppurutnity");
        view=inflator.inflate(R.layout.tablayout,container,false);
        Log.d("onCreateView","Here I m OKKKKKKKKKKKKKKKKKKKKKKKKKK");
        if (android.os.Build.VERSION.SDK_INT > 9) {
            StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
            StrictMode.setThreadPolicy(policy);
        }

        mViewPager = (ViewPager)view.findViewById(R.id.viewpager);
        mTabHost = (TabHost) view.findViewById(android.R.id.tabhost);
        Log.d("I m not ohk","I go from here");
        return view;
    }

}

tablayout.xml this layout I used in another project works very fine without any problem even it gets displayed but here I need to overlap it over the Listfragment.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"

        </LinearLayout>

detailfragment.xml contains the two fragments the ContactDetails fragment works very fine but the fragment ContactHistory with tabhost and ViewPager doesn't get displayed and I also don't get any error
