What is it?

ListViewAnimations is a free code library for Android that allows you to add animations to ListView easily, as can be seen in the example:

Library usage example

You can download and check usage tutorials, as well as more information this link .

How does it work? - Installation

The library consists of separate modules:

  • lib-core : The library core also contains appearence animations (< in> fade-in ).
  • lib-manipulation : contains manipulations of ListView items, such as "Swipe-to-Hide" and "Drag-and-Drop" (famous < in> Drag-and-Drop )
  • lib-core-slh : An extension of lib-core to support StickyListHeaders .

Example use StickyListHeaders

Nowyouhavethreeoptions:

Addthefollowinginyourbuild.gradle:

repositories{mavenCentral()}dependencies{compile'com.nhaarman.listviewanimations:lib-core:3.1.0@aar'compile'com.nhaarman.listviewanimations:lib-manipulation:3.1.0@aar'compile'com.nhaarman.listviewanimations:lib-core-slh:3.1.0@aar'}

Oryoucandownloadsomefiles:

The .jar files should be added to your libs folder or added as external jars in the build path of your project.

Or you can also add the following to your pom.xml :

<dependency>
    <groupId>com.nhaarman.listviewanimations</groupId>
    <artifactId>lib-core</artifactId>
    <version>3.1.0</version>
</dependency>
<dependency>
    <groupId>com.nhaarman.listviewanimations</groupId>
    <artifactId>lib-manipulation</artifactId>
    <version>3.1.0</version>
</dependency>
<dependency>
    <groupId>com.nhaarman.listviewanimations</groupId>
    <artifactId>lib-core-slh</artifactId>
    <version>3.1.0</version>
</dependency>

How does it work? - Get to work!

Now that you've installed everything, let's go to the animations in a ListView .

1. Appearance animations (fade-in)

This animation serves as a fade-in (animation on the opacity of an object or media, increasing as a function of time).

MyAdaptermyAdapter=newMyAdapter();AlphaInAnimationAdapteranimationAdapter=newAlphaInAnimationAdapter(myAdapter);animationAdapter.setAbsListView(mListView);mListView.setAdapter(animationAdapter);

YoucancreateyourownAnimationAdapter,oruseoneofthepredefinedones,whichare:

  • AlphaAnimationAdapter
  • ScaleInAnimationAdapter
  • SwingBottomInAnimationAdapter
  • SwingLeftInAnimationAdapter
  • SwingRightInAnimationAdapter

Intheexample,AlphaInAnimationAdapterwasused.

2.DynamicListView

FirstincludethisinyourXMLlayout:

<com.nhaarman.listviewanimations.itemmanipulation.DynamicListViewandroid:id="@+id/dynamiclistview"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

3. Drag and Drop

In order to do this, call by enableDragAndDrop() in your DynamicListView and seven which items will be eligible to be caught, this you can use TouchViewDraggableManager :

mDynamicListView.enableDragAndDrop();
mDynamicListView.setDraggableManager(new TouchViewDraggableManager());

You can also start drag using startDraggin(int) , for example in a OnItemLongClickListener :

mDynamicListView.enableDragAndDrop();
mDynamicListView.setOnItemLongClickListener(
    new OnItemLongClickListener() {
        @Override
        public boolean onItemLongClick(final AdapterView<?> parent, final View view,
                                       final int position, final long id) {
            mDynamicListView.startDragging(position);
            return true;
        }
    }
);
  

Note: This feature is only possible on devices that run ICS (API 14) or higher.

For other purposes, you can take a look on this page in English .

I did not find anything about ListViewAnimation in the official documentation, you're probably quoting the ListViewAnimations , which is a lib that helps you in animations related to ListViews and GridViews . As for usage, you have a example application in the repository, integration is reasonably well exemplified.
