android-parallaxheaderviewpager's Issues

Scroll from PagerSlidingTabStrip

Hello Guys
The scroll is not working when i try to do it from the PagerSlidingTabStrip view.. How can i fix that?
Thanks in advance

How can i use this with gridview.

Inside SampleListFragment you are adding a blank header what if we want to use a GridView or scrollView rather than ListView and in adjustScroll we can setSelectionFromTop in listView or setScroll in ScrollView but what about GridView ( setSelection is not working perfectly )?
How can we achieve that without setting a blank header.

SwipeRefreshLayout is invisible

SwipeRefreshLayout is invisible, the swipe is work, onRefresh event is called, but the progress bar is invisible

Can not even run the app

Lots of errors when i try to build it.I think you must provide at least runnable code here

Dynamic HeaderImage

Hi , this demo working perfectly but i want to set dynamic images in header , i am getting URL from server so after downloading image from Server i need to set it in header .Please let me know how it will work .

Listitems of variable size?

Will this work properly if the row elements in the listview are of different sizes?
The way getScrollY (on the basis of which Header is animated) is implemented, it looks as though scrolling will be smooth only if all elements are of equal size. Kindly correct me if I am wrong.

public int getScrollY(AbsListView view) {
    View c = view.getChildAt(0);
    if (c == null) {
        return 0;
    }

    int firstVisiblePosition = view.getFirstVisiblePosition();
    int top = c.getTop();

    int headerHeight = 0;
    if (firstVisiblePosition >= 1) {
        headerHeight = mHeaderHeight;
    }

    return -top + firstVisiblePosition * c.getHeight() + headerHeight;
}

Fixed Size Header.

Hello,

In your sample app you have kept the header size fixed.

As per my app's requirement i cannot keep it fixed.
I tried by changing the Header-FrameLayout and FakeHeader-FrameLayout to WrapContent. But it does not work. The Header gets fixed and does not scroll with the ListView.

Can you please help me??

Please provide a demo

How to use this for fragments containing layouts other than ListViews?

The ViewPager in my app contains layouts with ListViews, ExpandableListViews, ScrollView, RelativeLayout and LinearLayout(with a MapFragment in this).
Everything works fine for Tabs containing ListViews and ExpandableListViews! But.. not for the other layouts? How to proceed now?

Please Help me I'm trying to build an app for our college Festival.

Thanks!

How to use with RecycleView or with ScrollView?

Can you post an example with ScrollView or with the new RecycleView class? Thanks

Help to use StickyListHeader

Hello, is it possible to use the library StickyListHeader (https://github.com/emilsjolander/StickyListHeaders) in your library?

I managed to use it correctly, but the headers do not stay below the ViewPager

Do you have a solution?

Sorry for my bad English I'm a french developer :)

when the listview is empty or cannot fill viewpager, the header automatically scrolls down.

as title. finally resolved by adding transparent layout to listview.

Not able to run code

Get Google PlayStand like ViewPager with a promotional ViewPager on the top layout

Can you please look at this question posted on SO:

Is there any easy way to achieve this

AppCompat v21 support?

Is there any way to get it working with the new appcompat support library? They introduced many changes on it and I don't find how to solve the problem of getActionBarIconView() always returning null.

Android.R.id.home returns null

I am using the same logic but getActionBarIcon() returns null. Actually android.R.id.home as a imageview is returning null.

@TargetApi(Build.VERSION_CODES.HONEYCOMB)
private ImageView getActionBarIconView() {

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
        return (ImageView) findViewById(android.R.id.home);

    }

    return (ImageView) findViewById(android.support.v7.appcompat.R.id.home);
}

Help me please!!!!

Replace List View with Linear Layout?

I want to use different layout in different tabs. How to do that?

Inactivity crash

After leaving the app in the background for a long while, you will get a crash when changing tab and and the header wont scroll...

add some animation

if the content of viewpager is little,can add some moving animation with header

Scroll reset problem

maybe it is by design but the lists scroll position resets when changing tab

How to Keep Track of Scroll Position and Header Size Across Tabs (Enhancement) :)

I was having some problems implementing this because of it losing scroll position and not maintaining header size across tabs when I tried to get the scroll position working.

This is my solution:

A way you can hack it to make it remember scroll position as well as keep track of the header state across all tabs.

Not the best solution but might give someone some ideas:

SampleListFragment:

}

I added a hashmap that keeps track of the scrolling position for each listview. Views settings are automatically added to the hashmap and then their settings are loaded back when needed.

I also wrote a function in the activity that basically keeps track of the scroll height. Obviously the header height is changing in 1 listview and when we switch tabs we want to be able to ask the activity the height of the original header. We then do a check to see if it was the minimum header size or the full header size then we simply do some tweaking to align things a bit.

There are probably better ways to do it... this is just an idea that allows you to keep track of scroll positions across listviews and maintain headers.

:)

If anyone comes up with anything better or this helps in anyway do let me know.

Image is not displayed initially

Hi,

I edited the layout a bit for my project's purpose as below:

    <com.flavienlaurent.notboringactionbar.KenBurnsView
        android:id="@+id/header_picture"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:src="@drawable/picture0" />

// I replace the imageview with a custom view

        <ImageView
            android:id="@+id/header_logo"
            android:layout_width="@dimen/header_logo_size"
            android:layout_height="@dimen/header_logo_size"
            android:layout_centerInParent="true"
            android:layout_alignParentTop="true"
            android:paddingTop="15dp"
            />

        <ImageView
            android:id="@+id/header_logo_hide"
            android:layout_width="0dp"
            android:layout_height="0dp"
            android:layout_centerHorizontal="true" />

        <TextView
            android:id="@+id/header_name"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_below="@+id/header_logo"
            android:layout_centerHorizontal="true
            android:paddingTop="20dp"
            android:textSize="20dp"
            android:textStyle="bold" />
  </RelativeLayout>

</FrameLayout>

and I use this layout in a fragment, so the code was changed a bit to work in fragment

• The view was inflated in onCreateView and onActivityCreated.
• Instead of interpolating header_logo to the action bar icon, I want header_logo to interpolating to the header_logo_hide. The code changed:
  interpolate(mHeaderLogo, mHeaderLogoHide, sSmoothInterpolator.getInterpolation(ratio));

Issue: when open the fragment, the header_logo is not displayed unless I make a initial action like scroll or touch or click.

Please help to advise me.

can replace Translation animation to setpadding

i can't click pagerSlidingTabStrip's children. because os 2.3 can't support layout change after animated moving. so finally write this
if (pre Honeycome) {
mHeader.setPadding(0, Math.max(-scrollY, mMinHeaderTranslation), 0, 0);
} else {
ViewHelper.setTranslationY(mHeader, Math.max(-scrollY, mMinHeaderTranslation));
}

How to use RecyclerView instead of ListView?

Hello,

I am using this library for my App. But i have Recycler view with in the tabs and your example is for ListView.
