In Code (Java)

// Flips the view with or without animation
mYourFlipView.flipTheView();
mYourFlipView.flipTheView(false);

// Sets and Gets the Flip Animation Duration in milliseconds (Default is 400 ms)
mYourFlipView.setFlipDuration(1000);
int dur = mYourFlipView.getFlipDuration();

// Sets and gets the flip enable status (Default is true)
mYourFlipView.setFlipEnabled(false);
boolean flipStatus = mYourFlipView.isFlipEnabled();

// Sets and gets the flip on touch status (Default is true)
mYourFlipView.setFlipOntouch(false);
boolean flipTouchStatus = mYourFlipView.isFlipOnTouch();

// Get current flip state in enum (FlipState.FRONT_SIDE or FlipState.BACK_SIDE)
EasyFlipView.FlipState flipSide = mYourFlipView.getCurrentFlipState();

// Get whether front/back side of flip is visible or not.
boolean frontVal = mYourFlipView.isFrontSide();
boolean backVal = mYourFlipView.isBackSide();

// Get/Set the FlipType to FlipType.Horizontal
boolean isHorizontal = mYourFlipView.isHorizontalType();
mYourFlipView.setToHorizontalType();

// Get/Set the FlipType to FlipType.Vertical
boolean isVertical = mYourFlipView.isVerticalType();
mYourFlipView.setToVerticalType();

// Get/Set if the auto flip back is enabled
boolean isAutoFlipBackEnabled = mYourFlipView.isAutoFlipBack();
mYourFlipView.setAutoFlipBack(true);

// Get/Set the time in milliseconds (ms) after the view is auto flip back to original front side
int autoflipBackTimeInMilliseconds = mYourFlipView.getAutoFlipBackTime();
mYourFlipView.setAutoFlipBackTime(2000);

// Sets the animation direction from left (horizontal) and back (vertical)
easyFlipView.setFlipTypeFromLeft();

// Sets the animation direction from right (horizontal) and front (vertical)
easyFlipView.setFlipTypeFromRight();

// Sets the animation direction from front (vertical) and right (horizontal)
easyFlipView.setFlipTypeFromFront();

// Sets the animation direction from back (vertical) and left (horizontal)
easyFlipView.setFlipTypeFromBack();

// Returns the flip type from direction. For horizontal, it will be either right or left and for vertical, it will be front or back.
easyFlipView.getFlipTypeFrom();

Flip Animation Listener

EasyFlipView easyFlipView = (EasyFlipView) findViewById(R.id.easyFlipView);
easyFlipView.setOnFlipListener(new EasyFlipView.OnFlipAnimationListener() {
            @Override
            public void onViewFlipCompleted(EasyFlipView flipView, EasyFlipView.FlipState newCurrentSide) 
            {
                
                // ...
                // Your code goes here
                // ...
                
            }
        });

❌ Known Issues

The EasyFlipView doesn't flip when used in RecyclerView. This is because the EasyFlipView uses the onTouch() method to intercept the touch events and flip the view accordingly. One easier solution is to disable the flipOnTouch attribute in XML by this.

app:flipOnTouch="false"

Now, your RecyclerView will scroll but the EasyFlipView will not flip or animate on touch etc. You will have to manually flip the view by calling the method mYourFlipView.flipTheView() inside the adapter or ViewHolder class of the RecyclerView. For example,

public class MyRecyclerViewAdapter extends RecyclerView.Adapter<MyRecyclerViewAdapter.ViewHolder> {

    private List<Object> mData;
    private LayoutInflater mInflater;
    private ItemClickListener mClickListener;

    // data is passed into the constructor
    MyRecyclerViewAdapter(Context context, List<Object> data) {
        this.mInflater = LayoutInflater.from(context);
        this.mData = data;
    }

    // inflates the row layout from xml when needed
    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = mInflater.inflate(R.layout.recyclerview_row, parent, false);
        return new ViewHolder(view);
    }

    // binds the data to the TextView in each row
    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        String textData = (String) mData.get(position);
        holder.myTextView.setText(textData);
    }

    // total number of rows
    @Override
    public int getItemCount() {
        return mData.size();
    }


    // stores and recycles views as they are scrolled off screen
    public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
        TextView myTextView;
	EasyFlipView myEasyFlipView;

        ViewHolder(View itemView) {
            super(itemView);
            myTextView = itemView.findViewById(R.id.tvAnimalName);
	    myEasyFlipView = itemView.findViewById(R.id.myEasyFlipView);
            itemView.setOnClickListener(this);
        }

        @Override
        public void onClick(View view) {
	    myEasyFlipView.flipTheView();
            if (mClickListener != null) {
	    	mClickListener.onItemClick(view, getAdapterPosition());
	    }
        }
    }

    // convenience method for getting data at click position
    String getItem(int id) {
        return mData.get(id);
    }

    // allows clicks events to be caught
    void setClickListener(ItemClickListener itemClickListener) {
        this.mClickListener = itemClickListener;
    }

    // parent activity will implement this method to respond to click events
    public interface ItemClickListener {
        void onItemClick(View view, int position);
    }
}

The EasyFlipView has a strange behaviour when the back and front layouts are a CardView. To workaround it, wrap your CardView in a FrameLayout or other ViewGroup.

Any idea why this is happening/what I'm doing wrong?

change flip mode in recyclerview

when I use flipview inside recyclerview some bugs happen
when scrolling, reused view that I need to change from back to front (or opposite), I tried to use flipTheView method withAnimate=false - but the result is seeing the back for second and then the front
I tried to use setFlipDuration(0) before, but the result of that is the animation stays with duration 0 for every next flipTheView call withAnimation=true

Creating the view programmatically

Hello, your code assume that the EasyFlipView is inflated from an xml layout. Building it programmatically will generate an NPE I.E here:

    public void setFlipDuration(int flipDuration) {
        this.flipDuration = flipDuration;
        ((Animator)this.mSetRightOut.getChildAnimations().get(0)).setDuration((long)flipDuration);
        ((Animator)this.mSetRightOut.getChildAnimations().get(1)).setStartDelay((long)(flipDuration / 2));
        ((Animator)this.mSetLeftIn.getChildAnimations().get(1)).setDuration((long)flipDuration);
        ((Animator)this.mSetLeftIn.getChildAnimations().get(2)).setStartDelay((long)(flipDuration / 2));
    }

because mSetRightOut will always be null as it is built in the "OnFinishInflate", which is not callable from outside and called only if the view is inflated from an XML layout

I would suggest to simply add a method (public) called setup() that is fired as well in OnFinishInflate but could allow people to build the view programmatically and setup later as needed.

Thanks!

Setting flipType to horizontal in XML doesn’t have effect

Same code as in the Readme

Unable to scroll EasyFlipView

Scrolling issue while trying to scroll the items of recycler view. Unable to scroll while clicking EasyFlipView ITEM_VIEW. And if we tried to scroll with other views rather than EasyFlipViewview is scrolling only in that case.

Question: Reverse the flipping direction?

Hi,

Thanks for making your library available! It's very much appreciated and is working great.

I appreciate it really is an "easy" library too :)

The one question I have is: is it possible to reverse the flipping direction? It would be nice to reverse flip when going from the back to the front.

Thanks!

Animation completion handler

Are you expecting to provide a way for users to set an animation completion handler? We can already get the duration of the animation, so we could just use a timer, but if the API is already doing something when the animation completes, it would be good to ensure that the user's completion tasks would be done after the API's.

FlipTheView just one time

hi, how can i use flipTheView to flip just one time ?

FlipView in ScrollView

if I use several flipViews in ScrollView, the ScrollView doesn't work.

Performed steps suggested for recyclerview but didnt helped

Clipping

Hey, the front/back views are clipped at the top and bottom at the EasyFlipView bounds while flipping (horizontal).
Is there way to fix this? I tried

android:clipChildren="false"
android:clipToPadding="false"

on the FlipView to no avail.

Can you control the angle of rotation?

With this library, it is possible to control the angle so that it is not 360 degrees of rotation, but only 180 degrees? or 90 degrees?

In Lib Module

Could not resolve com.wajahatkarim3.EasyFlipView:EasyFlipView:2.1.2

can't call method setClickListener in main activity

when use in recycleView
how can i call this method in main activity
// allows clicks events to be caught
void setClickListener(ItemClickListener itemClickListener) {
this.mClickListener = itemClickListener;
}

bug

android 4.4 运行时有旋转痕迹出现

backside unclickable

I want to add click things(not flip ,such as jump to ...) in backside . It does not work!
(我想在背面的view 添加点击事件 ， 但是不能生效)

setToHorizontalType and setToVerticalType not exist

Version 2.1.0
Can’t find such documented methods in the code.

View clipping

There's some noticeable clipping near the corners even in the preview gif itself:

I was wondering if there's a workaround to let the view overflow it's bounds, i.e., draw over other elements if needed to make the whole animation visible.

after using flipview my recylerview scroll is not working

Or how to manage both things

Thanks

[FEATURE REQUEST] Make it possible to have both cards share height of the higher one

First of all - Thank you for providing us with such a great and simple library! I love it and I'm generally delighted with how it works, but there's a problem that I see no simple way of fixing.

Currently, I see no other way for cards to have them share the height of the higher one other than hardcode height of both child fragments. I think that allowing the control of whether I want the other side visibility to be changed to INVISIBLE not GONE would help many people that want to display dynamic content in their FlipView.

Flip right to left

how to flip right to left, reverse of current flip

Regarding usage in android App

Can we use this flipview library in our android app which we will be putting in android playstore ?

Migrate to Maven Central

JFrog just announced that they'll be shutting down JCenter:
https://jfrog.com/blog/into-the-sunset-bintray-jcenter-gocenter-and-chartcenter/

Key dates are:

• February 28th: No more submissions will be accepted to Bintray, JCenter
• May 1st: Bintray, JCenter services will no longer be available

Hence this library should also be migrated to another maven repository like Maven central.

Build fails due to EasyFlipView dependency issue

My builds started failing today for some reason and I am getting this message

Could not determine artifacts for com.wajahatkarim3.EasyFlipView:EasyFlipView:2.1.2: Skipped due to earlier error

Any ideas about how to fix that?

Dynamic flip type leads to mirrored images and wrong flip animation

Nice library, thank you very much.
I'm using it with two image views.
Depending on a fling motion, the user is able to turn the image vertically (if swiping up or down) or horizontally (if swiping horizontally).
The type (from front or back, left or right) is changed accordingly.
This motion may be repeated as often as the user likes on the same.

A problem occurs, if a user swipes vertically and then horizontally (or vice versa).
Here's a little POC to show what I mean.

// the flip view flips on touch
findViewById<EasyFlipView>(R.id.flip_view).run {

    setToHorizontalType()

    // first click: everything is fine
    setOnFlipListener { _, _ ->
        setToVerticalType()

        // second click: mirrored image view, correct animation
        setOnFlipListener { _, _ ->
            setToHorizontalType()
            setOnClickListener(null)

            // third click: mirrored image view changes back (is now correct), wrong animation
            // following clicks: wrong animations but correct image views
        }
    }
}

This most probably has got something to do with the animations.
When you 'flip' the image view, it's being mirrored which doesn't matter if you mirror it back along the same axis.
But as soon as you mix vertical and horizontal mirroring, everything breaks.

Manually mirroring the image views via getChildAt(1).scaleY = -1f would probably be possible.
Nevertheless I think it would be best to keep track of these changes within the library.

I've hacked my way around the issue by stacking two flip views over one another and dynamically showing/hiding them.
One is used for vertical and the other one for horizontal flips.
This is dirty and I'm wondering, whether you've ever encountered this problem or use case.

NullPointerExcxeption on gestureDetector.onTouchEvent

Hi, i have just updated EasyFlipView in my application to new version 3.0.3

By click on ImageVew, that is in the EasyFlipView easyFlipView.addView(deckView) i immediatly have a NullPointerException:

Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'boolean androidx.core.view.GestureDetectorCompat.onTouchEvent(android.view.MotionEvent)' on a null object reference
2023-10-22 12:06:57.656 20805-20805 AndroidRuntime          com.app.demo             E  	at com.wajahatkarim3.easyflipview.EasyFlipView.dispatchTouchEvent(EasyFlipView.java:462)

I have cleaned up a job after updating to new EasyFlipView version.

my configuration of view:

EasyFlipView easyFlipView = new EasyFlipView(context);
easyFlipView.setToHorizontalType();
easyFlipView.setFlipTypeFromBack();
easyFlipView.setAutoFlipBackTime(5_000);

ImageView image = new ImageView(context);
...
easyFlipView.addView(image);

ImageView deckView = new ImageView(context);
...
easyFlipView.addView(deckView);

easyFlipView.setOnFlipListener(...);

layout.addView(easyFlipView, lp);

When adding multiple view with scrollview,it cant be scrollable.

How to flip inside listview?

Hello folks and Mr. Karim.

I am trying to do the easyflip manually, because I am using a List View, but with no success...
When I do the touch, the app closes...

is this possible to support API 14?

Scroll is not working

I used edit text in layout when content increased scroll view not working

If Keyboard appears on top of Flip view and then closed, Flip view is not visible after that.

If Keyboard appears on top of Flip view and then closed, Flip view is not visible after that. It reappears if touched on the placeholder

front views can be seen reversed for a short delay at the end of the animation

When I flip my component, at the end of the animation I can see through the back view for a short time. what I see is, for example, the text view of the front view reversed. It doesn't matter if I set a background to the view or not.

EDIT: I tested to put a very long animation time to see what happens.
It works well but at the end of the animation there is a flickering showing the front view flipped then the back view again (like if the back view disappeared for a short time)

Any clues?
Cheers!

App crashes on flipTheView() on some devices

Although the library works fine on most devices, my app crashes when calling the flipTheView() method on some devices like Huawai P20 Pro, Xiaomi A2 Lite.
Does anyone have any idea what this might be and how to fix it?
