}
the weird thing about this code is; while running the button changes the text value correctly in the first pager, and the seckond one but when it comes the third one while it changes the value it resets the first pagers shown value but the getText() method inherits the correct value but the text is frozen and it cant be changed any more, after that the other page's values cant be changed either, but the getText() method still works fine and gets the correct value.
any idea will speed up my debuging process thanx anyway...
Solution
adding this snipped solved the problem, it is a must to define borders to the pager
@Override
protected void onCreate(Bundle savedInstanceState) {
...
int size = sliderAdapter.slide_headings.length;
AktifHareket.setOffscreenPageLimit(size);
