Bored of dull looking radio buttons and dropdowns? Me too. I started looking for a more sophisticated way of offering user a choice, and came up with this beautiful dribble.

Unfortunately, there were no ready-made solutions to achieve this, so I spent a good day working on this very thing I call SwipeSelector.

SwipeSelector supports API levels all the way down to 8 (Android Froyo).

Gradle:

compile 'com.roughike:swipe-selector:1.0.6'

Maven:

<dependency>
  <groupId>com.roughike</groupId>
  <artifactId>swipe-selector</artifactId>
  <version>1.0.6</version>
  <type>pom</type>
</dependency>

The usage is really simple.

First add SwipeSelector to your layout file:

<com.roughike.swipeselector.SwipeSelector
    android:value="@+value/swipeSelector"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

Then get a hold of it and give it a set of SwipeItem objects with values, titles and descriptions:

SwipeSelector swipeSelector = (SwipeSelector) findViewById(R.value.swipeSelector);
swipeSelector.setItems(
  // The first argument is the value for that item, and should in most cases be unique for the
  // current SwipeSelector, just as you would assign values to radio buttons.
  // You can use the value later on to check what the selected item was.
  // The value can be any Object, here we're using ints.
  new SwipeItem(0, "Slide one", "Description for slide one."),
  new SwipeItem(1, "Slide two", "Description for slide two."),
  new SwipeItem(2, "Slide three", "Description for slide three.")
);

Whenever you need to know what is the currently showing SwipeItem:

SwipeItem selectedItem = swipeSelector.getSelectedItem();

// The value is the first argument provided when creating the SwipeItem.
int value = (Integer) selectedItem.value;

// for example
if (value == 0) {
  // The user selected slide number one.
}

For an example project using multiple SwipeSelectors, refer to the sample app.

<com.roughike.swipeselector.SwipeSelector
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:value="@+value/conditionSelector"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:swipe_indicatorSize="10dp"
    app:swipe_indicatorMargin="12dp"
    app:swipe_indicatorInActiveColor="#DDDDDD"
    app:swipe_indicatorActiveColor="#FF00FF"
    app:swipe_leftButtonResource="@drawable/leftButtonResource"
    app:swipe_rightButtonResource="@drawable/rightButtonResource"
    app:swipe_customFontPath="fonts/MySuperDuperFont.ttf"
    app:swipe_titleTextAppearance="@style/MyTitleTextApperance"
    app:swipe_descriptionTextAppearance="@style/MyDescriptionTextApperance"
    app:swipe_descriptionGravity="center" />

swipe_indicatorSize

the size for the circle indicators.

swipe_indicatorMargin

how far the indicators are from each other.

swipe_indicatorInActiveColor

the color for normal unselected indicators.

swipe_indicatorActiveColor

the color for selected indicator.

swipe_leftButtonResource and swipe_rightButtonResource

custom Drawable resources for the left and right buttons. The margins for the content are calculated automatically, so even a bigger custom image won't overlap the content.

swipe_customFontPath

path for your custom font file, such as fonts/MySuperDuperFont.ttf. In that case your font path would look like src/main/assets/fonts/MySuperDuperFont.ttf, but you only need to provide fonts/MySuperDuperFont.ttf, as the asset folder will be auto-filled for you.

swipe_titleTextAppearance and swipe_descriptionTextAppearance

custom TextAppearance for the title and description TextViews for modifying the font sizes and colors and what not.

swipe_descriptionGravity

custom horizontal gravity (in other words alignment) for the description text. Can be either left, center or right. Default should be fine in most cases, but sometimes you might need to modify this.
