Viewpager doesn't update/loads xml items

I solved the question with onclicklistsner issue with viewpager but now I noticed, that it depends on all Elements in XML Layout files.

I implemented a ViewPager with that Tutorial: tutsplus

Now I have the Problem, that all the Objects I defined in XML are instantiated correct (not null in Debuggin mode after findViewById etc) but I can't reffer to them. To understand it better here my PagerAdapter:

class MyPagerAdapter extends PagerAdapter {



    public int getCount() {

        return 3;

    }



    public Object instantiateItem(View collection, int position) {



        LayoutInflater inflater = (LayoutInflater) collection.getContext()

                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);



        int resId = 0;

        switch (position) {

        case 0:

            resId = R.layout.settings_view;



            break;

        case 1:

            resId = R.layout.push_view;

            break;

        case 2:

            resId = R.layout.listen_view;

            break;



        }

        View view = inflater.inflate(resId, null);



        ((ViewPager) collection).addView(view, 0);



        return view;





    }



    @Override

    public void destroyItem(View arg0, int arg1, Object arg2) {

        ((ViewPager) arg0).removeView((View) arg2);



    }



    @Override

    public boolean isViewFromObject(View arg0, Object arg1) {

        return arg0 == ((View) arg1);



    }



    @Override

    public Parcelable saveState() {

        return null;

    }

    public int getItemPosition(Object object) {

        return POSITION_NONE;

    }





}

and here my implementation of the adapter and a bit of sample code:

ViewPager myPager = (ViewPager)findViewById(R.id.pager);

        adapter = new MyPagerAdapter();

       myPager.setAdapter(adapter);

       myPager.setCurrentItem(0);

Spinner spinner = (Spinner)listenView.findViewById(R.id.Dashboard_chooser); Button push = (Button)pushview.findViewById(R.id.pushbutton);

ArrayAdapter spinnerArrayAdapter = new ArrayAdapter(getApplicationContext(),android.R.layout.simple_spinner_item, si);





            spinner.setAdapter(spinnerArrayAdapter);







push.setOnClickListener(new OnClickListener() {





            public void onClick(View v) {



//do something

});

neither the Button nor the Spinner are doing anything. They are both instantiated correct, but I cannot click the buton nor gets the Spinner filled with the Array of SpinnerItems.

In Debu Mode I looked up, that both of them get instantiated, the SpinnerItemArray (si) gets it's values and so on.

By the way, all the things worked before I implemented the ViewPager,and the buttons are also working when setting an android:onClick in XML and then defining the method in code but that won't work for the Spinner , so I think it must be something wrong with either the instantiateItem Method or something similar.

Does anyone here knows the Problem? Would be too cool if somebody could help. Yours Flo
