The background is not shown at all!

Hi,

as I see, there are already a couple of questions, how to make your library work with the popular ViewPagerIndicator library.

Can you please just delete a ParallaxViewPager#addOnPageChangeListener(OnPageChangeListener listener) method, to make it possible to call the native method from ViewPager#addOnPageChangeListener(OnPageChangeListener listener)?
So it becomes possible to use not only 2 listeners.
Actually secondOnPageChangeListener field is unnecessary now, it can be removed too.

thanks in advance & best regards

Love the component you've made!

However, I'm encountering a couple of problems, which I haven't been able to save yet.
If I leave out the background of the XML, the app crashes because of an inflation exception. Even if it is specified in the activity. Might be nice to fix this one at a certain time.

The other thing:
The background is not drawn before there was a swipe/motion event. Have you ever experienced this? I think it happened after I made the FragmentStatePagerAdapter so that it could add Fragments dynamically.

Any of this sounds familiar? I'm still looking to see if I can find anything in the code, if so, I will let you know as well.

This would make the library compatible with other libraries that set their own PageChangeListener. This is required to make this work with the popular ViewPagerIndicator library.

See: http://stackoverflow.com/questions/25366899/viewpagerindicator-does-not-allow-setbackgroundresource-on-viewpager

app:viewpager_hideToolbarAndTitle="false"

Then scroll down just a little bit (halfway)

Then swipe left/right

Suddenly the actionbar has background color and tabstrip also.

Also sometimes when sticky the whole header gets pulled up beyond the status bar, sometimes opposite it gets pulled to almost middle of the screen.

More an report for the author to look for bugs. Tested on Samsung S6 Edge, Android 5.1

Hi. It seems that every time the soft keyboard pops up, the method onSizeChanged is called and the background resource drawn again, which means that the image will sqeeze vertically. It would be nice if the pager included a "allowBackgroundResize(boolean allow)" method, so we could disable it if, for example, the keyboard pops up.

Maybe some states need to be saved? As a habit, I check "Don't keep activities" at system settings when debugging. After I switch to other app and switch back, which means the activity is destroyed, The background image disappears.

I carefully check the background, and find that the image is still there actually, but it's placed at the right side of screen; I can only see the image at the right edge of screen at first page of viewPager.

Any idea to fix it?

this is my code:
<com.andraskindler.parallaxviewpager.ParallaxViewPager
android:id="@+id/pager"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:background="@drawable/background"
android:layout_weight="1"
android:visibility="gone"/>
and the page width: return(0.8f);
the problem is when u go to the next page 0.2 background of the page is white

Please put a small sample for the library.

@Override
public View onCreateView(LayoutInflater inflater,
                         @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_home, container, false);

    parallaxHorizontalViewPager = ((ParallaxViewPager) view.findViewById(R.id.parallaxviewpager));

    parallaxHorizontalViewPager.setAdapter(new PageHorizontalHomeAdapter(getFragmentManager()));

    parallaxHorizontalViewPager.setScaleType(ParallaxViewPager.FIT_WIDTH);
    parallaxHorizontalViewPager.setBackgroundResource(R.drawable.image);
    return view;
}


@Override
public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
    parallaxHorizontalViewPager.setCurrentItem(1, false);
}

setCurrentItem makes black background. It's like it can calculate the width or something

While using ParallaxViewPager with CirclePageIndicator of https://github.com/JakeWharton/Android-ViewPagerIndicator, the parallax background is not shown. So what needs to be done to use ParallaxViewPager with CirclePageIndictor . And lastly, great library. Thanks

Can we customize the parallax to a video background? like a 5 sec video on a continuous loop.

If the ViewPager is on the first page, screen rotation works just fine. But if on any of the other pages and I rotate my phone, the background image disappears, resulting, in my case, in a white background.

I have tried in vain to reset the background resource on onConfigurationChange().

I am using a resource with the dimensions 1500x1000 as background, set with setBackgroundResource()
