como atualizar o layout (todos os layouts em diferentes guias) nas guias do Android Tabs com fragmento
como atualizar o layout em uma aba no Android Tabs com fragmento, tenho mais de duas abas com layout diferente
Tenho a primeira guia com layout xml, como mostrado abaixo (fragment_main.xml):

No layout acima, incluí o header_layout.xml, que está tendo o TextView comum para o meu layout, ou seja, para fragment_main.xml e fragment_keyboard.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:id="@+id/headerTextView"
style="@style/TitleText"
android:text="" />
</RelativeLayout>
Preciso atualizar o TextView depois de analisar os valores de um arquivo json, meu problema é que, quando altero a guia, o header_layout.xml não é atualizado, então, como atualizar isso? então com
/**
* Returns a new instance of this fragment for the given section
* number.
*/
public static PlaceholderFragment newInstance(int sectionNumber) {
PlaceholderFragment fragment = new PlaceholderFragment();
Bundle args = new Bundle();
args.putInt(ARG_SECTION_NUMBER, sectionNumber);
fragment.setArguments(args);
return fragment;
}
@Override
public void onViewCreated(View v, Bundle savedInstanceState) {
super.onViewCreated(v, savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_main, container, false);
TextView textView = (TextView) rootView.findViewById(R.id.section_label);
textView.setText(getString(R.string.section_format, getArguments().getInt(ARG_SECTION_NUMBER)));
//Switch to different layout accordingly
switch (getArguments().getInt(ARG_SECTION_NUMBER))
{
case 1: {
rootView = inflater.inflate(R.layout.fragment_main, container, false);
break;
}
case 2: {
rootView = inflater.inflate(R.layout.fragment_receipt, container, false);
break;
}
case 3: {
rootView = inflater.inflate(R.layout.fragment_totals, container, false);
break;
}
case 4: {
rootView = inflater.inflate(R.layout.fragment_keyboard, container, false);
break;
}
case 5: {
rootView = inflater.inflate(R.layout.fragment_keylock, container, false);
break;
}
}
return rootView;
}
}
No método parseJsonResponse (), defino o valor para os objetos no layout
String UIFooter = ResponseHeaderObject.getString("FOOTER");
//Set Header Display
headerTextView =(TextView) findViewById(R.id.headerTextView);
headerTextView.setText(UIHeader);
