通过将片段添加到现有ListView来丢失数据

Question

I am trying to populate my ListView with a Footer. For that reason I created a Fragment. But I have problems passing data to the fragment. On a different place it worked just fine, the way I have done it.

    listView1 = (ListView) findViewById(R.id.listView1);     

    MenueAdapter adapter = new MenueAdapter(MainActivity.this,
            R.layout.mainview_menue_item_row, data_Storage_news, 
            getWindowManager().getDefaultDisplay().getWidth());    


    Intent intent_onTv = new Intent(context,
            OnTvFragment.class);

    intent_onTv.putExtra("data_Storage_tv", data_Storage_tv);

    OnTvFragment frag = new OnTvFragment();
    frag.setArguments(intent_onTv.getExtras());
    FragmentTransaction ft = getSupportFragmentManager().beginTransaction();        
    ft.commit();    

    LayoutInflater inflater = getLayoutInflater();      
    View footer = inflater.inflate(R.layout.ontv_fragment, null);       

    getSupportFragmentManager().executePendingTransactions();

    listView1.addFooterView(footer);       
    listView1.setAdapter(adapter);

The Fragment contains a ViewFlipper and works perfectly fine in another activity.

Anyone a clue what I'm doing wrong or can tell me a proper way how it's done?

Adding a Fragment as Footer to a ListView - My solution:

ListView.LayoutParams lp = new ListView.LayoutParams(ListView.LayoutParams.WRAP_CONTENT, ListView.LayoutParams.WRAP_CONTENT);        

    View footer = new View(listView1.getContext()); 

    footer = ((LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.on_tv_fragment_empty, null);        
    footer.setLayoutParams(lp);     

    OnTvFragment frag = new OnTvFragment();
    FragmentTransaction ft = getSupportFragmentManager().beginTransaction();        
    ft.replace(R.id.ll, frag).commit();       
    getSupportFragmentManager().executePendingTransactions();

    listView1.addFooterView(footer);
    listView1.setAdapter(adapter);

Make sure, that footer is inflating an empty FrameLayout like:

    <?xml version="1.0" encoding="utf-8"?>
    <FrameLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"     
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"   
    android:background="@layout/gradient_box"
    android:id="@+id/ll"
    />        

to avoid the following bug: How to make fragment transaction when clicked on a listitem?

My result looks like this:

Hope this helps anybody :)
