Viewpager doesn't update/loads xml items

Question

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
