SwipeStack

SwipeStack

A simple, customizable and easy to use swipeable view stack for Android.

QuickStart

Include the Gradle dependency

dependencies {
    compile 'link.fls:swipestack:0.3.0'
}

Use it in your layout file

1. Use the link.fls.swipestack.SwipeStack view in your XML layout file
2. Set the parent view's clipChildren attribute to false

Example:

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:clipChildren="false">

    <link.fls.swipestack.SwipeStack
        android:id="@+id/swipeStack"
        android:layout_width="320dp"
        android:layout_height="240dp"
        android:padding="32dp"/>

</FrameLayout>

Create an adapter

Create an adapter which holds the data and creates the views for the stack.

Example:

…

Assign the adapter to the SwipeStack

Last, but not least, assign the adapter to the SwipeStack.

Example:

SwipeStack swipeStack = (SwipeStack) findViewById(R.id.swipeStack);
swipeStack.setAdapter(new SwipeStackAdapter(mData));

That's it!

Callbacks

Currently SwipeStack implements the following callbacks:

• the SwipeStackListener notifies you when a view was swiped to the left / right or when the stack becomes empty.
• the SwipeProgressListener notifies you about the progress when the user starts / stops dragging a view around.
