castorflex/verticalviewpager

Copy pasted version of the support ViewPager, but vertical!

verticalviewpager's Issues

Gradle: Could not find element /manifest/application.

There is an issue in the manifest merger that requires the library to have an application node in its manifest.
Solution is to add tag to the mainfest.

With added a ListView to VerticalViewPager , I found event conflict.

I'll wait for your answer.

Allow the changing of ViewPager speed when scrolling

When using a vertical ViewPager the pages are a lot longer and take longer to drag to the next page rendering it very difficult for the user to change pages by dragging unless they fling.

Would be nice to be able to change the distance in which the ViewPager moves per pixels dragged, then working with a vertical ViewPager would be a lot more pleasurable experience when dragging between pages (it will be doable without a fling).

VerticalViewPager scroll doesnt work when listview is used inside one of the fragment.

Hi,
VerticalViewPager scroll doesn't work when a list-view is used inside it. I guess the list-view vertical scroll motion is conflicting with the vertical scroll of the the pager...Can you look at it.
thanks

pageAdapter.notifyDataSetChanged() could not let the VerticalViewPager refresh its layout

1. I add some elements to VerticalViewPager.
2. clear the elements and add some new elements
3. use pageAdapter.notifyDataSetChanged(). but it doesn't work.
   why?

key event bug

please patch the code

    public boolean executeKeyEvent(KeyEvent event) {
        boolean handled = false;
        if (event.getAction() == KeyEvent.ACTION_DOWN) {
            switch (event.getKeyCode()) {
            --case KeyEvent.KEYCODE_DPAD_LEFT:
            ++case KeyEvent.KEYCODE_DPAD_UP:
                    --handled = arrowScroll(FOCUS_LEFT);
                    ++handled = arrowScroll(FOCUS_UP);
                    break;
            --case KeyEvent.KEYCODE_DPAD_RIGHT:
            ++case KeyEvent.KEYCODE_DPAD_DOWN:
                    --handled = arrowScroll(FOCUS_RIGHT);
                    ++handled = arrowScroll(FOCUS_DOWN);
                    break;
                    ......
            }
        }
        return handled;
    }

Incorrect scrolling behavior when fake dragging.

fakeDragBy(float) does not work as expected.

setOnPageChangeListener doesn't work

I've been trying to figure out why setOnPageChangeListener doesn't work with the VerticalViewPager. I do the next:

pagerView.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
      @Override public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
       ...
      }

      @Override public void onPageSelected(int position) {
       ...
      }

      @Override public void onPageScrollStateChanged(int state) {
        i...
      }
    });

Methods are never called.

Using setCurrentItem() brings no visual effect

As in title, besides that everything works perfect. On (FragmentPagerAdapter) myAdapter.getItem() I'm returning custom class which returns simple View in onCreateView().

Plus when I enable debug mode (DEBUG == true) I get:

VerticalViewPager with ViewPager

Hello,

I'm using the VerticalViewPager, and one of the Fragment is a ViewPager. Something like this:
View1 - View11 - View12 - View13
View2
View3
View4
View5
It seems to work fine, but when I scroll all the way down, then come back, the views View1 and View11 are gone. But if I scroll all the way to View13, the come back, I can see them again...

I know this is out of the scope of this class, but was just wondering if you had any hint...

thanks!

Using AspectRatioImageView and longer images in verticalViewPager

Hi,
This issue is different from the last one. I am using AspectRatioImageView in VerticalViewPager and my images are now longer that one page of view pager. This makes the viewpager to overlap some images on each other. Is there anyway to tell the viewpager the real height of each page instead device height?
Thanks

Weird Scroll Glitch with Clickable views

When testing on device (Samsung S6, API 21), there is a weird behavior .. if you are on any fragment after the first one, clicking on anything that has 'clickable' attribute to it, would cause the view to slightly scroll above or down to a small amount and then it goes back in right place .. if you click again, it may not show but if you scroll up/down a bit and retry it, it shows that weird behavior again .. I guess the issue is in calculating yOffset in PageScrolled ((int)scrollY) inside PerformDrag() .. Also, I tried everything related to 'focousable', 'focousableInTouchMode', 'DecendantFocousability' but that never worked .. again this is only on device and reproducible using the default sample provided..

Please help .. I invested so much time converting this to Xamarin only to find the issue on device :(

Adding View Pager indicator

Hi,first of all thanks for such a great library. I am using this VerticalViewPager in one of my app. I used this "https://github.com/JakeWharton/Android-ViewPagerIndicator" library to show view pager indicator.

Below is my Activity code:

    mViewPager = (VerticalViewPager) findViewById(R.id.view_pager);
    mViewPagerIndicator = (CirclePageIndicator) findViewById(R.id.view_pager_indicator);
    mViewPagerIndicator.setViewPager(mVerticalViewPager); //need to pass the object of support v4         ViewPager

The third line in the above code gives error. This is because setViewPager() method takes object of android.support.v4.View.ViewPager as argument and I am sending object of VerticalViewPager as argument.

How can I show view pager indicator in your VerticalViewPager? Please help me out.

set height of every page of ViewPager

Hi,
I am using your code in landscape mode and I have ImageView in it. the image is big and user needs to scroll vertically. but VerticalViewPager goes to next page when scrolling down.
Is there any way to solve this issue?
Thanks
