Sample app	Sample usage

A custom made SeekBarheavily inspired bythis great widget from Instagram.

Add a dependency to yourbuild.gradle:

dependencies {    implementation'com.bernaferrari.emojislider:emojislider:0.3.2'}

It is fully stable, but there might be some changes to the API, like improved naming, or some small changes on functions. You can use it fine already.

Download the sample app to experience it.

• Customize with xml using custom handy attributes.
• Customize in your activity, fragment or dialog.
• Creating new widget programmatically.

Place theEmojiSlider in your layout.

<com.bernaferrari.emojislider.EmojiSliderandroid:id="@+id/slider"android:layout_width="match_parent"android:layout_height="wrap_content"/>

Important: if you want to have the emoji floating above the slider when it is pressed/dragged, you need to supply a view, preferably on the foreground, to be drawn and tell the slider who the view is.Example:

<?xml version="1.0" encoding="utf-8"?><FrameLayoutxmlns:android="http://schemas.android.com/apk/res/android"xmlns:app="http://schemas.android.com/apk/res-auto"android:layout_width="wrap_content"android:layout_height="wrap_content"><com.bernaferrari.emojislider.EmojiSliderandroid:id="@+id/slider"android:layout_width="match_parent"android:layout_height="match_parent"android:padding="72dp"/><Viewandroid:id="@+id/slider_particle_system"android:layout_width="match_parent"android:layout_height="match_parent"/></FrameLayout>

   findViewById<EmojiSlider>(R.layout.slider).sliderParticleSystem= slider_particle_system

To track the current position of the slider, set thepositionListener, as shown below:

val slider = findViewById<EmojiSlider>(R.id.slider)slider.positionListener = { p -> Log.d("MainActivity", "current position is: $p" )}

You can also track the beginning and completion of the movement of the slider, using the following properties:startTrackingListener andstopTrackingListener. Examples below:

slider.startTrackingListener = { /* action on slider touched */ }slider.stopTrackingListener = { /* action on slider released */ }

Here is a random example in Kotlin:

// Kotlinval slider= findViewById<EmojiSlider>(R.id.slider)slider.sliderParticleSystem= slider_particle_systemslider.position=0.25fslider.averagePosition=0.75fslider.allowReselection=trueslider.colorStart=Color.REDslider.colorEnd=Color.YELLOWslider.setResultDrawable(profilePictureBitmap)

Here is a random example in Java:

// JavafinalEmojiSliderslider =findViewById(R.id.slider);slider.setStartTrackingListener(newFunction0<Unit>() {@OverridepublicUnitinvoke() {Log.d("D","setBeginTrackingListener");returnUnit.INSTANCE;    }});slider.setStopTrackingListener(newFunction0<Unit>() {@OverridepublicUnitinvoke() {Log.d("D","setEndTrackingListener");returnUnit.INSTANCE;    }});// Or Java 8 lambdaslider.setPositionListener(pos -> {Log.d("D","setPositionListener");returnUnit.INSTANCE;});

Check the sample app for more. The sample app even shows how to use Glide to load a Bitmap into a round drawable.

All customizable attributes for EmojiSlider:

Of course, some attributes might have better names than others and documentation might not be perfect. If you find anything wrong or weird,let me know.
