I have added 2 features:

1. Modified the "inflate" method for the "undo" layout, now a parent is provided otherwise the layout_* parameters of the "undo" view are ignored (It's impossible to set a fixed height to the undo view directly from the xml)
2. Added a new api setKeepHeight(boolean) to the ContextualUndoAdapter: with this is possible to set the height of the undo view as the height of the content view. The default is "false"

Thanks, Giuseppe

I know you rejected the previous pull request, but check this out. I fixed most of the issues. Very minor problems remained with drag&drop. Try the example app on an emulator and see for yourself. 10% of potential customers is a lot for applications with million or more installs. It would be good to support API >= 8.

• Add support for API >= 8 for the example app with AppCompat library.
• Updated Drag&Drop code to use NineOldAndroids. Fixed most of the problems for API < 14. The only problem left is that the mobileView does not become invisible...
• Fixed a problem which prevented running the app on an Emulator without Google Play Store.
• Fixed issue #254 (looks like recycling was still a problem on >= 14 but much less visible than < 14)

Splits library in lib-core and lib-manipulation. Basically, everything in package com.nhaarman.listviewanimations.itemmanipulation has moved to lib-manipulation.

Libraries can be accessed like this:

compile 'com.nhaarman.listviewanimations:lib-core:3.0.0'
compile 'com.nhaarman.listviewanimations:lib-manipulation:3.0.0'

lib-manipulation requires lib-core to be present. For now, -SNAPSHOT releases are present.

Fixes #190

Fix #66

I don't know what will happen if you use this in a Dialog. I'm going to test this code the next week. And probability I will rebase it.

I post it looking for comments and issues.

This causes issues when a parent view tries to steal a MotionEvent using onInterceptTouchEvent (such as a DrawerLayout opening the side menu).

I've added an implementation for ACTION_CANCEL (looking at the latest romannurik code). This solves issue #65 on your issue tracker.

I hope I did this pull request right, I'm a bit new to the entire Github thing.

I am not really sure how to deal with item click on ContextualUndoAdapter. The example doesn't mention it. There are at least two ways item click is handled:

1. By hooking a View.OnClickListener to a view in the row. This view will no longer respond to swipe though.
2. By hooking AdapterView.OnItemClickListener to the listview. In this case we need to restrict which clicks go to that listener. Consider the case of Undo Layout that looks like If mUndoActionId corresponds to "Tap to Undo" view then clicking the other views (like "Deleted") will still trigger OnItemClick. I propose root view of the undo layout is set with null listener. With it other views except mUndoActionId will not respond to click. But I do not know if other people have different needs / customizations of their own Undo Layout.

This is kind of a big update.

The idea was to add swipemenu support using the full power of ListViewAnimations I based my work in this ios implementation

So i did it in steps :

• use nineoldandroids everywhere and bring back support to < 14
• added removal animation support
• refactored the logic of DynamicListView for draganddrop, swipetodismiss, and other future features to work together
• replace SwipeUndoView with DynamicListItemView : simple view which can support all features
• implemented swipe menus

I hope you are going to like it and that you will be willing to merge it ;) In the future i want to add custom transformation support just like MGSwipeTableCell does. I prepared everything to do so.

Resolve the problem with Timer in SwipeDismiss. As I understood the problem still exist, so is when we do deletion some one, and in time of counting do deletion some other below that, we have problem with the timer, so it is resolve the problem. I guess there exist better solution, but this is also is worked fine.

To reflect the change made here https://code.google.com/p/dashclock/source/browse/main/src/com/google/android/apps/dashclock/ui/SwipeDismissListViewTouchListener.java

certainly seems to make the swipe action a lot more usable.

This implements a ContextualUndoAdapter, used as a Decorator to add a GMail-like Swipe To Dismiss + Contextual Undo behaviour. To see it in action navigate to the ContextualUndoActivity in the example.

There's still lots of duplicated code in the OnTouchListener, but I wanted to keep the pull request small without changing too much existing code. This should be fairly intuitive to use, even without commenting the code. If you prefer to have Javadoc comments on the main functionalities please let me know and I'll try to follow your style.

Hello. This fixes crashes on my phone (out of bound Exception... adapter getItemId gets called after getCount()) Also : I need onItemMoved to be called even when the user drops it in the same position :

My use case : When I start dragging, I make some changes to the list (I model a tree) When the user stops dragging, I need to revert those changes. If the onItemEvent isn't fired when the user drops it in the same position, my data is in an inconsistent state.

Also, the developper can check if original position == new position in onItemMoved

Thanks for this library

I'm not sure if this is actually useful for anyone, but in my app it was useful to be able to have a drag and drop interface where some elements could not be dragged below a certain point. I changed Swappable to return a boolean which says if the swap actually happened. If it doesn't, it prevents the animation from playing. This prevents the animations from freaking out when you drag over something that you can't drag to.

Removed android:allowBackup="true" because it forces the Android Project I'm working on to also use it otherwise it will throw a Manifest Merger conflict.

Hi all,

I use listviewanimations in my app, and sometime app force close when i drag and drop item in listview

I don't understand why althought at line 588 in DragAndDropHandler.java really check not null before

for uses where u need to remove more than one object at a time prior to notifying data set changes

i have a gridview with AbsListView.MultiChoiceModeListener implemented so a user can check multiple objects and click delete - with a loop and remove() once at a time, many notify were called, messing up view hierarchy a bit/glitchy

I use the library for tree data structure. Before I start dragging item in tree-view, I must collapse selected view if it has some children. Then I have to expand it again after dropping.

Example:

listView.setOnItemLongClickListener(
        new AdapterView.OnItemLongClickListener() {
            @Override
            public boolean onItemLongClick(final AdapterView<?> parent, final View view,
                                           final int position, final long id) {
                myAdapter.setCollapsed(position);
                new Handler().postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        listView.startDragging(position);
                    }
                }, 50);
                return true;
            }
        }
);

listView.setOnItemMovedListener(new OnItemMovedListener() {
    @Override
    public void onItemMoved(int to, int from) {
        myAdapter.setExpanded(from);
    }

});

listView.setOnItemMovingCanceledListener(new OnItemMovingCanceledListener() {
    @Override
    public void onItemMovingCanceled(int originalPosition) {
        myAdapter.setExpanded(originalPosition);
    }
});
