MyListFragment.java this extends ListFragment and onListItemClick() I need to migrate to another two Fragments which should be displayed over this ListFragment.
我不知道如何解决这个错误我被困了3天帮助我。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。
public void onListItemClick(ListView l, View v, int position, long id) {
Log.d("ListCLicked","Yes Clicked");
//String clickedDetail = (String)l.getItemAtPosition(position);
/*
* The second fragment not yet loaded.
* Load MyDetailFragment by FragmentTransaction, and pass
* data from current fragment to second fragment via bundle.
*/
MyDetailFragment myDetailFragment = new MyDetailFragment();
Bundle bundle = new Bundle();
//bundle.putString("KEY_DETAIL", clickedDetail);
myDetailFragment.setArguments(bundle);
Log.d("ListCLicked1","Yes Clicked");
FragmentTransaction fragmentTransaction =
getChildFragmentManager().beginTransaction();
Log.d("ListCLicked2","Yes Clicked");
fragmentTransaction.add(R.id.tablistfragment, new MyDetailFragment());
Log.d("ListCLicked3","Yes Clicked");
fragmentTransaction.commit();
}
MyDetailFragment.java is Fragment that an inflate to detailfragment.xml containg two fragments to be overlapped over the MyListFragment. MyListFragment is containg loaders and which log my phonebook contacts and form a list out of them on click of any List Item I need to get the fragment containing the details about the contact.Help Help Help Help help Help!!!!!!!!!

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"

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

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"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >
<TabHost
android:id="@android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<TabWidget
android:id="@android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="0"
android:orientation="horizontal" />
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="0dp"
android:layout_height="0dp"

<android.support.v4.view.ViewPager
android:id="@+id/viewpager"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="top" />
</LinearLayout>
</TabHost>
</RelativeLayout>
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
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

</RelativeLayout>
我没有收到任何错误，但是当我尝试显示它显示的联系人片段时，我的片段反对片段没有显示出来。
答案 0 :(得分：0)
据我所知，可能是因为嵌套片段。
嵌套片段并不是解决问题的好方法。 您最好使用自定义视图：扩展Linear / RelativeLayout，并将您的内容放入其中。
更改
public class MyDetailFragment extends Fragment {
到
public class MyDetailView extends LinearLayout {
如果需要还有其他一些调整
然后您不需要使用片段管理器，您可以通过xml或编程方式添加MyDetailView。
希望有所帮助
