Binary XML 

<fragment class="com.myexample.template.VoiceTemplate" 
    android:id="@+id/voiceListFragment"
    android:layout_width="0dp"
    android:layout_height="match_parent"
    android:layout_weight="1" 
/>

Line number 19 contains inside onCreateView of TextVoiceFragment.class which is Fragment #2 in this case

 return inflater.inflate(R.layout.text_voice_fragment, container, false);

Line number 82 contains in code inside onActivityCreated of VoiceTemplate.class which extents ListFragment & a ListFragment #2

// 
getListView().setOnItemClickListener( new OnItemClickListener(){

    @Override
    public void onItemClick(AdapterView<?> adapterView, View view,
            int position, long arg3) {
        // TODO Auto-generated method stub
    }

 });

i have tried replacing Fragment #2 with FragmentActivity as follows

enter image description here

but in that case i am getting following error

 java.lang.ClassCastException: com.myexample.template.TextVoiceFragment

here TextVoiceFragment is Tab second

Solution

  • I'm not sure that this is creating your problem, but in the future you might have others because nested fragments are not supported.

    You can read this answer of a Android Framework Engineer about that: Android: Can you nest Fragments?
