Adding folding cell dynamically (with PHP script)

Hi,
First thanks for this awesome component. But my question is if it's possible to add to a LinearLayout some folding cell with some various content depending on my result of my request PHP script (i have already made it with some ImageView, getting data from database is not a problem).
Thanks for your consideration and sorry for my bad english i'm french.

Foldingcell not working on Fragment

I tried to use the Folding-cell on my Fragment , but it won t work ...
Here`s my xml :
<com.ramotion.foldingcell.FoldingCell
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/folding_cell"
android:layout_width="0dp"
android:layout_height="wrap_content"
tools:layout_editor_absoluteY="75dp"
tools:layout_editor_absoluteX="8dp">

</com.ramotion.foldingcell.FoldingCell>

Here is my Fragment Java Class :

@OverRide
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {

View view = inflater.inflate(R.layout.fragment_orders_layout,container,false);

final FoldingCell fc = (FoldingCell) view.findViewById(R.id.folding_cell);
fc.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        fc.toggle(false);
    }
});

return view;

}

I`d be glad to use help..
Tnx..

Prospective error with recycleview

I used this lib without problem for a normal listview. Now I need to use recycleview. Animation work weel, but the size of border of fold raming the same. Instead border of view should increase of some dp to give a 3d sensation to the user.

Bad folding animation

I imported and run your example of folding-cell-listview-example. Unfortunately it seems that there is a strange folding animation. When the animation of unfolding starts there is always a bug with the first fold (or the last if folding). It looks like the animation starts from the top of the screen and not from the point it's in. Any way of fixing it?

Here is a sample ( second list option was clicked btw ):

Unfold the last two lines, the last line is not complete and cannot be folded

In rapid succession unfold the last two lines, in the last line is not fully expanded when the penultimate line, the last line is not complete and cannot be folded

Weird folding animation

I'm currently using the folding cell examples + one with a layout of my own, no behavior problems but in all the projects, including the example you provide, while expanding or collapsing the cell edges tent to cover a good portion of the screen in a completely unnatural way. I'm using normal Listviews and android 6.0 on a Nexus 5.
I attached a link to a screenshot to make the problem clear, in my opinion, while folding, the cell should never overlap with other listview elements, this 3D effect almost give the sensation that the user is being hit. I'd like to know if there is something that could be done to solve this issue

After fold/unfold a few time list misaligned

Screen:
http://i.imgur.com/Tyk4EV5.png

There is unnecesary extra space. Need to recreate list to get it aligned properly again. Then it works, i can fold/unfold list without an issue. But after some time, I'm getting invalid alignment again.

I am unable to reproduce it with your sample project. Any ideas what could case that? The only difference is I used ConstraintLayout for folded/unfolded layouts, does it matter? And second difference, your sample has latest sources added as module, my app uses jar (maybe outdated?)

Any ideas? I'm stuck actually, are there any commits not included in released version? (maybe I should recompile latest codes from github?).

how can I get cell's state, fold or unFold?

java.lang.IllegalArgumentException: width and height must be > 0 in RecyclerView

I am using folding cell in RecyclerView.

My FoldingCell click view setup in RecyclerAdapter like below:

mViewHolder.itemView.setOnClickListener(new View.OnClickListener() {
@OverRide
public void onClick(View v) {
((FoldingCell) v).toggle(false);
// register in adapter that state for selected cell is toggled
contentAdapter.registerToggle(mViewHolder.getAdapterPosition());
}

I get following error whenever scroll up or scroll down & that Item is not visible in RecyclerView.

Dynamic Height For Content_view

I am trying to add dynamic content in Content_View, So it can varies ex. For some there will be only 3 lines and another has 5 or you can say 6 7 lines so i want Folding cell to dynamically adjust to the height of content. Is it possible??

folding cell in CardView with elevation and radius corner

Hi, I have a RecyclerView in my activity. I used folding-cell library to expand each CardView. but because my CardView has elevation and cardCornerRadius it gets ugly. because when it wants to unfold list_item_feed_expand first it doesn't have radius corner and shadow and when animation get completed it gets shadow and corner. it is the same for folding. it first removes radius corner and shadow and then it fold it
can you tell me how to correct this? is there anyway to solve it?

Calling toggle(true) o unfold(true) makes the cell disappear

I'm having trouble with the folding cell on a recycler view. After trying to deal for hours with animation problems, and for testing purposes, I set to true the skip animation booleans to at least try to mitigate the issues I'm having (most of them already reported on other issues). Doing that I found that when I call toggle(true) or unfold(true) on a cell it disappear, but fold(true) does not.

Folding Cell title question

Hi!
Thanks for this lib!

How can I "unfold" my cell without hiding title? Ie: it now works this way:
title shown, content hidden -> click -> title hidden, content shown.

How can I reach this behaviour?
title shown, content hidden -> click -> title shown, content shown.

Thanks!

In RecyclerView bug

When you expand the item in the list, the fast slider list will cause item error to be resumed.I does not see callbacks that are executed after folding animation.

Update content view height

I want to update content view height after performing some operations (adding some text or images). But height still stays fixed.

But calling foldingCell.contentView.requestLayout() does not do anything.

Where is the trick?

Please, help me.

Why this library's minSdkVersion was set to 17?

I tried it on a phone device whose sdkversion is 14,and I didn't found any problems.

Glitched animation when unfolded for first time

Hi, I'm trying to solve an issue with Folding Cell element. When I unfold it for the first time, next items jump to their final position for a fraction of second and only then is their position animated according to the folding anim. It seems as if the whole layout does not have infomation about the final size of unfolded item so it needs one unfolding to compute it first. If I collapse the same item and then unfold it second time, it all works perfectly. Any idea what can I do about it ?

folding-cell:backSideColor not working

Item strange scroll

Hello there!

I have a problem when I unfold my items. If the items are in the lower half of the screen there is no problem, but if the items are in the upper half of the screen, the item "auto scroll" to keep the position.

Check this gif:

https://i.imgur.com/NzbVI1A.gifv

i get this error : java.lang.IllegalStateException: Additional flips count is too small

Process: sinadalvand.a30nama.co.a30nama, PID: 4943 java.lang.IllegalStateException: Additional flips count is too small at com.ramotion.foldingcell.FoldingCell.calculateHeightsForAnimationParts(FoldingCell.java:292) at com.ramotion.foldingcell.FoldingCell.unfold(FoldingCell.java:134) at com.ramotion.foldingcell.FoldingCell.toggle(FoldingCell.java:224) at sinadalvand.a30nama.co.a30nama.Recycle.PostPageRecycleAdapter$DownloadHolder$3.onItemClick(PostPageRecycleAdapter.java:134)

i use this list view in Recycle view when i touch card i receive this error .

what is this meaning?

The first flip is very big.

Thanks for great work
I run the demo on my galaxy s6 edge with Android 6
the first flip is very big. it takes the whole screen. it is not like the gif displayed in repository where flip size should match displayed layout size.
the only parameter to configure is "cell:additionalFlipsCount" which control additional flips. my issue with first flip size

Pass info throw a listener

I'm trying to pass a info contained on the item (like price) to a new activity when press the Request button, so i need get first the info using something like "items.get(i).getBoxID()" the problem is when i do
for(int i = 0; i< items.size(); i++) {
final ArrayList idboxes = new ArrayList<>();
final int finalI = i;
items.get(i).setRequestBtnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                Toast.makeText(getApplicationContext(), "CUSTOM HANDLER FOR FIRST BUTTON", Toast.LENGTH_SHORT).show();
                System.out.println(items.get(i).getBoxID());
            }
        });

}

on the println there is a error with the i variable the code need to be final but that doesn't do what i need
any idea?

How to unfold the selected cell and fold others

Is there a way/method to unfold only the selected cell and fold the others ?

folding does not work, if i use switch or toggle switch

Dear sir,
I use your example of folding list view. If i put a switch on title view then it does not unfold at all. You are using textview as button in your code. Sir but i need to use switch or toggle. help me please.
thank you,
Khemraj
