Is it possible to change the image resource of the image view in the fragment on button click? for example i have there a method onclicklistener for button benefit_babies... i want to set the image resource into the int array benefitBaby on click of the button.

imageview.setImageResource(id) where id is in your int array. See the documentation for ImageView for details. It is the same as you have in your code just in the onClick() handler.
setImageResource
void setImageResource (int resId)
Sets a drawable as the content of this ImageView.
This does Bitmap reading and decoding on the UI thread, which can cause a latency hiccup. If that's a concern, consider using setImageDrawable(android.graphics.drawable.Drawable) or setImageBitmap(android.graphics.Bitmap) and BitmapFactory instead.
Hi everyone thanks for the help. I solved it by using view page adapter. Every onclick button I will change the adapter. Thank you!!

how?
i do make a single main_layout and set a FrameLayout in order to put fragments with different layouts.so i have a screen with different layouts.

I've downloaded the Navigation Drawer example from the developers guide, I try to implement a GridView into an Activity of one of the options of the Drawer, but in execution time the GridView doesn't appears, the IDE doesn't show me any errors and in an example apart I can do it de GridView successfuly, How do I correct this problem?
My code is here:
In the MainActivity I use the same like the example with
Fragment fragment;
FragmentManager fragmentManager;
fragment = new inicioFragment(R.layout.inicio);
fragmentManager = getFragmentManager();
fragmentManager.beginTransaction().replace(R.id.content_frame, fragment).commit();

GridView gv = (GridView)findViewById(R.id.gridView1);
gv.setAdapter(new ImageAdapter(this.getApplicationContext()));
gv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v, int position, long id){
String g=Integer.toString(position);

imageView.setLayoutParams(new GridView.LayoutParams(85, 85));
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
imageView.setPadding(13, 13, 13, 13);
} else {

Thanks for your collaboration!!
Try to change InicioActivity into a fragment.
And check this question. I think you are facing the same problem.
The following worked for me. In Android Studio:
1) Create a new Navigation Drawer Activity from the list of activity templates.
2) Note that several layout files will be created for you, including a content_main.xml. Replace the XML in the content_main.xml file with your <GridView> XML.
3) Create the relevant XML files or Java classes for the GridView, eg. the ImageAdapter class and an XML file for the GridView item layout.

If I leave
//lv.setAdapter(listAdapter);
commented, it loads, but as soon as I uncomment it, it crashes with the following error:
12-06 11:28:05.240: E/AndroidRuntime(1362): java.lang.ClassCastException: android.widget.TextView cannot be cast to android.widget.ListView
with reference to this precise line.
You make cast checkBox to ListView !
It should be like that.
ListView lv = (ListView) getActivity().findViewById(R.id.list);
I gusse here is the error in your code:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_papers, container, false);
ListView lv = (ListView) getActivity().findViewById(R.id.check1);
//Here your casting checkBox to Listview Pleas Check it out
listAdapter = new PaperAdapter(getActivity(),papers);
//lv.setAdapter(listAdapter);
return v;
}
just replace it like
ListView lv = (ListView) v.findViewById(R.id.ListviewName);
I've come across several examples of the page curl animation as well as viewflippers . Is it possible to navigate between children of a viewflipper via a page curl animation . The animations i have applied to viewflippers till now were very basic such as a slide-in/slide-out and I was wondering if the same could be done/has already be implemented using a page-curl animation.
There is an open source android project here: http://code.google.com/p/android-page-curl/.
I found another one here: https://github.com/harism/android_page_curl/.
But there is no native implementation if that is what you are asking.
You need to import one module library for this, from HERE
After that use following code:-
item_page.xml
