Stepper Touch for Android based on a Material Up showcase designed by Oleg Frolov

In the latest version of the support library (25.3.0) a new class SpringAnimation was made available. I wanted to test this out and not long after that I found Stepper Touch, a concept made in FramerJS, on Material Up. I took this oppertunity to play with SpringAnimations.

Try it yourself:

• Step 1. Add the JitPack repository to your build file

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

• Step 2. Add the dependency (only for androidx projects)

dependencies {
    implementation 'com.github.DanielMartinus:Stepper-Touch:1.0.1'
}

If you haven't migrated your project to AndroidX use:

dependencies {
    implementation 'com.github.DanielMartinus:Stepper-Touch:0.6'
}

<nl.dionsegijn.steppertouch.StepperTouch
        android:id="@+id/stepperTouch"
        android:layout_width="100dp"
        android:layout_height="40dp" />

val stepperTouch = findViewById<StepperTouch>(R.id.stepperTouch)
stepperTouch.minValue = 0
stepperTouch.minValue = 10
stepperTouch.sideTapEnabled = true
stepperTouch.addStepCallback(object : OnStepCallback {
	override fun onStep(value: Int, positive: Boolean) {
    		Toast.makeText(applicationContext, value.toString(), Toast.LENGTH_SHORT).show()
	}
})

StepperTouch stepperTouch = findViewById(R.id.stepperTouch);
stepperTouch.setMinValue(0);
stepperTouch.setMaxValue(3);
stepperTouch.setSideTapEnabled(true);
stepperTouch.addStepCallback(new OnStepCallback() {
    @Override
    public void onStep(int value, boolean positive) {
        Toast.makeText(getApplicationContext(), value + "", Toast.LENGTH_SHORT).show();
    }
});

You're able to further customize or set initial values with styled attributes:

1. Add res-auto to your xml layout if you haven't yet

xmlns:app="https://schemas.android.com/apk/res-auto"

2. After that the following attributes will become available:

app:stepperBackgroundColor=""
app:stepperButtonColor=""
app:stepperActionsColor=""
app:stepperActionsDisabledColor=""
app:stepperTextColor=""
app:stepperTextSize=""
app:app:stepperAllowNegative=""
app:app:stepperAllowPositive=""
