Android viewpager animation

I have come across the same issue. the following is my conclusion:

When the page is actually changed onPageSelected will be called. But it's called before the animation.

When the animation stopped , onPageScrollStateChanged will be called with state SCROLL_STATE_IDLE.

So you have to combine this two function calls to get your function called.

Good Luck.

private class PageChangeListener implements OnPageChangeListener { @Override public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) { } @Override public void onPageSelected(int position) { isPageChanged = true; } @Override public void onPageScrollStateChanged(int state) { switch (state) { case ViewPager.SCROLL_STATE_IDLE: if (isPageChanged) { updateCurrentPage();//this will be called when animation ends isPageChanged = false; } break; case ViewPager.SCROLL_STATE_DRAGGING: break; case ViewPager.SCROLL_STATE_SETTLING: break; } } } 

You can use a OnPageChangeListener..

viewPager.setOnPageChangeListener(new OnPageChangeListener() { @Override public void onPageSelected(int arg0) { // The code you want to run when scrolling is complete } @Override public void onPageScrolled(int arg0, float arg1, int arg2) {} @Override public void onPageScrollStateChanged(int arg0) {} }); 

When a new page is selected, onPageSelected() gets called.
