What is Listviewanimations and how to use it?

Question

I wanted to understand what the ListViewAnimations is (a component, a Framework?) and how it works.

Answer 1

What is?

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

---

Example of library usage

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

How does it work? - Installation

The library consists of separate modules:

• lib-core: the library core, also contains appearence animations (fade-in).
• lib-manipulation: contains the manipulations of the ListView, as the "Drag-to-Hide" (Swype-to-Dimiss) and the "Drag-and-Drop" (famous, Drag-and-Drop)
• lib-core-slh: an extension of lib-core to support the StickyListHeaders.

Example of the use of StickyListHeaders

Now you have three options:

Add the following to your build.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'
}

Or you can download some files:

• lib-core
• lib-manipulation
• lib-core-slh
• NineOldAndroids.jar

The . jar files should be added to your folder libs or add them as jars external 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 one ListView.

1. Appearance animations (fade-in)

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

MyAdapter myAdapter = new MyAdapter();
AlphaInAnimationAdapter animationAdapter = new AlphaInAnimationAdapter(myAdapter);
animationAdapter.setAbsListView(mListView);
mListView.setAdapter(animationAdapter);

You can create your own AnimationAdapter, or use one of the default ones, which are:

• AlphaAnimationAdapter
• ScaleInAnimationAdapter
• SwingBottomInAnimationAdapter
• SwingLeftInAnimationAdapter
• SwingRightInAnimationAdapter

In the example, the AlphaInAnimationAdapter.

2. Dynamiclistview

The DynamicListView is a class that features effects like Drag-and-Drop, Swype-to-Dismiss and animations to remove, move and insert items. It was made to match the above descriptions conveniently.

First include this in your XML layout:

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

3. Drag and Drop

To do it, call for enableDragAndDrop() in his DynamicListView and seven which items will be eligible to be picked up (drag), for this you can use the TouchViewDraggableManager:

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

You can also start the 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 functionality is only possible on devices running ICS (API 14) or higher.}

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

Answer 2

I found nothing on ListViewAnimation in the official documentation, you are probably quoting the Listviewanimations, which is a lib that helps you in animations related to ListViews and GridViews. As for the use, has an application of example in the repository, the integration is reasonably well exemplified.
