IllegalStateException on adding parallax header #12

A full stack trace would be better. This error suggest me that the app is trying to add a view that already has a parent. Also I think |

I tried replacing "this" with a inner class implementation, but am still getting the error. Here is the complete stack trace 03-06 16:00:11.081 16363-16363/com.designs.zoomonkey.writetrack E/AndroidRuntime﹕ FATAL EXCEPTION: main

Can you show me the XML for R.layout.fragment_chart_detail? |
|
I also tried passing null as the parent when inflating it, but still no use. |
|
Are you familiar with android debugging? If so add a breakpoint on
|
|
I checked and it's null.. It's null when it is inflated as well. |
|
Well it doesn't make any sense then :\ could you please comment: And try again with just the super call? |
|
I figured it out... I was calling setParallaxHeader twice. Once in onCreate and another time when my loader is finished with the data load. I removed the first call and it started working.. haha.. I got a question. What should one do if he wants to change the header view once you set it once? Like this example: I setParallaxHeader once. And then I have to change the header to another on some user interaction. Obviously creating a new adapter and calling setParallaxHeader is not working. Any workaround? |
|
I am using Loaders to load data to the recycler view and because of that, when the underlying data changes, the loader is called again which calls the setParallaxHeader method. This is getting me same error... If tried putting a check in the setParallaxHeader method like And even like this But neither of them gives me a consistent solution. |
|
Could you try this setParallaxHeader method? |
|
I tried and it's not working. It's not going into the if condition that you put in. i.e holder is null. I think the problem is that mHeader is already a child of the previous CustomRelativeWrapper, but somehow the reference to that is lost. Cause when I debugged, I could see even when mHeader was null, the header we pass in has a parent. public void setParallaxHeader(View header, final RecyclerView view) {
mRecyclerView = view;
if (header.getParent()!=null) {
RecyclerView.ViewHolder holder = view.findViewHolderForPosition(0);
if (holder != null) {
((CustomRelativeWrapper) holder.itemView).removeAllViews();
mHeader = new CustomRelativeWrapper(header.getContext(), mShouldClipView);
mHeader.addView(header, new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
((CustomRelativeWrapper) holder.itemView).addView(mHeader, new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
return;
}
} else {
mHeader = new CustomRelativeWrapper(header.getContext(), mShouldClipView);
mHeader.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT));
mHeader.addView(header, new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
}
view.setOnScrollListener(new RecyclerView.OnScrollListener() {
@Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
super.onScrolled(recyclerView, dx, dy);
if (mHeader != null) {
mTotalYScrolled += dy;
translateHeader(mTotalYScrolled);
}
}
});
}Here it is going into the loop, and it works the first time it gets called(but the UI becomes weird). From the next time I'm getting the error. So when I looked into it what I found out was:
If there was a way to add the header directly to the holder, then it might work. I'm not sure though. What do you think? |
|
This might work but only if the header is currently visible because if not the holder will return null. Could you try and see if it works. If so we can start working from here. |
|
Tell me something. Is the new header you're trying to set the same size of the old one? Because if so I might have a working solution on my hands. |
|
Yeah, Its the same header, in fact, with some updated values.. If I can get a reference to the header, I should be able to update it. |
|
So if it's the same header a simple getHeader returning mHeader don't work? Something like Then you can get your view by simple calling |
|
I just had this idea while driving back from work. getHeader might not work On Mon, Mar 9, 2015, 9:46 PM Pedro Oliveira [email protected]
|
|
If that doesn't work try this adapter: |
|
I tried it with getheader, but not working. I tried the new Adapter, also not working(on first try). Will look into it further tomorrow. I have modified your adapter to use Cursors. I did not touch any of your methods, but added some other. The full code is below. I am not sure if that is causing a problem package com.designs.zoomonkey.writetrack.lib.parallaxrecyclerview;

Hey, great news.. I found a workaround and it is working. First I tried getting the parent of the header I'm passing, removing it, and then pass it to the setParallaxHeader method. But that got me weird results. The header itself was missing. But then, I tried inflating the header every time the loader completes. It is a little expensive, but seems to be working.. P.S - using your old adapter itself. |
|
Hey, I have the same problem you've got, I want to set the parallaxHeader multiple times. I'm using the old adapter, I'm not completely understand your workaround solution, can you paste some code here. Thank you very much. @manujosephv Here is the set header code: private void setHeader(boolean hasLogin) {
Log.d(FRAGMENT_TAG, "set header");
View header;
if (hasLogin) {
// todo: fix the header
header = LayoutInflater.from(getActivity()).inflate(R.layout.header_login, makeOrderList, false);
// todo: init the header's child views
} else {
header = LayoutInflater.from(getActivity()).inflate(R.layout.header_unlogin, makeOrderList, false);
}
adapter.setParallaxHeader(header, makeOrderList);
adapter.notifyDataSetChanged();
}Every time, I inflate a header view, and then set it, but the header won't change. |

Hi,
I was trying to implement parallax scrolling using this awesome library. But I ran into some problems. Am not sure I'm doing this right(first time android programmer). I'm getting this on adding parallaxheader.
I'll just give you a brief idea of what I did. I have a chart which is the header.
So I extended your ParallaxRecyclerAdapter with a custom constructor, overrode some methods, and named it StatsAdapter
And overrode setParallaxHeader like this
And in the Fragment from which I'm loading the recyclerview, I did this
Any idea why I'm getting this error?
