Transitions and fragments

Question

For my app's UI, I use Transitions and Fragments. In the onCreateView function of my first Fragment, I launch a Transition to change the display from a first Scene to a second Scene. Afterwards, when I click on a Button, I start another Transition to show some kind of "splashscreen" represented by a third Scene and, in it's onTransactionEnd, I try to change the Fragment with myView.postDelayed(new myRunnableForChangingFragment(),1000).

In debug mode, I see my Runnable is correctly launched, but the new Fragment doesn't replace the first one... Nevertheless, something did happen : I have to click two times on the back button to return to my first Fragment. In fact, it seems the Fragment is activated but not visible...

Any idea about how I could fix that?

As asked in the first comment, here's the code I use to change the Fragment:

    fragment=new mySecondFragment();
    transaction=getActivity().getFragmentManager().beginTransaction();
    transaction.replace(R.id.Conteneur, fragment,"Fragment tag");
    transaction.addToBackStack(null);
    transaction.commit();

I can add that this code launched from outside the onTransitionEnd works perfectly.

The xml file for the "container" :

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:id="@+id/Conteneur"
   android:orientation="vertical"
   android:layout_width="fill_parent"
   android:layout_height="fill_parent">     
</LinearLayout>

The xml file for the first and the second scene (the only difference ; buttons are set invisible in code in the first one) :

<TextView
    android:id="@+id/TitreJeux"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:layout_marginBottom="@dimen/MargeVerticaleBoutonsInterfaceJeux"
    android:lines="1"
    android:text="@string/app_name"
    android:textColor="#FFFF00"
    android:textSize="35sp"
    android:textStyle="bold"
    android:typeface="serif"/>

<vd63.jeux.JeuAnimationRapide.BoutonInterface
    android:id="@+id/BoutonOptions"
    android:layout_width="wrap_content"
    android:layout_height="0dp"
    android:layout_gravity="center"
    android:layout_marginTop="@dimen/MargeVerticaleBoutonsInterfaceJeux"
    android:layout_weight="1"
    android:background="@drawable/bouton_jouer"
    android:text="@string/BoutonOptions"
    android:textColor="@color/CouleurTexteBoutons"
    android:textSize="25sp"
    android:typeface="serif"/>

The xml fle for the "splash" scene :

<?xml version="1.0" encoding="utf-8"?> <LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
          xmlns:tools="http://schemas.android.com/tools"
          android:id="@+id/EcranChargement"
          android:orientation="vertical"
          android:gravity="center"
          android:background="@drawable/fond_interface"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          tools:context=".JeuAnimationRapide">

<ImageView
    android:id="@+id/VD63"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/vd63"/>

<ImageView
    android:id="@+id/Chargement"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/chargement"/>

I transition from scene one (button invisible,simple Slide) to scene 2 then back to scene 1 (Slide again) then to the "splash" scene (with a Fade transition).

When you switch from fragment one to fragment two use below code It works for me I hope it will help you.

Fragment fragment = SearchActivity.newInstance(context);
String tag = fragment.toString();
getFragmentManager().beginTransaction()
.addToBackStack(tag)       
.replace(R.id.fragment, new SearchActivity())
.commit();

Use addToBackStack when you want to come back to this fragment again on backpress otherwise you don't need to add addTobackstack
