PulseCountDown in Android with Example

PulseCountDown in Android with Example

PulseCountDown is not a standard view in the Android SDK, but assuming it's a custom view or a library that gives a pulsating countdown effect, let's imagine how you might create and use such a component in Android.

I'll provide a basic example of how you could create a pulsating countdown in Android:

1. Create a Custom View

First, let's create a simple custom view that can pulsate:

class PulseCountDownView @JvmOverloads constructor( context: Context, attrs: AttributeSet? = null, defStyleAttr: Int = 0 ) : View(context, attrs, defStyleAttr) { private val paint = Paint(Paint.ANTI_ALIAS_FLAG).apply { color = Color.BLUE } private var radius = 0f private var pulseIncrement = 5f private val animator = ValueAnimator.ofFloat(0f, 100f).apply { duration = 1000 repeatCount = ValueAnimator.INFINITE addUpdateListener { radius = (it.animatedValue as Float) + 50f invalidate() } } override fun onDraw(canvas: Canvas?) { super.onDraw(canvas) canvas?.drawCircle(width / 2f, height / 2f, radius, paint) } fun startPulsating() { animator.start() } fun stopPulsating() { animator.cancel() } }

2. Use the Custom View

Include it in your XML layout:

<com.yourpackage.PulseCountDownView android:id="@+id/pulseView" android:layout_width="200dp" android:layout_height="200dp" />

In your Activity or Fragment:

val pulseView: PulseCountDownView = findViewById(R.id.pulseView) pulseView.startPulsating() // You can stop it using: // pulseView.stopPulsating()

This example creates a simple pulsating circle, but you can expand on this to incorporate countdown numbers, different shapes, or more complex animations.

Remember to handle lifecycle events appropriately to start, pause, or stop the animation when the activity or fragment is paused, resumed, or destroyed. This will prevent any memory leaks or unnecessary animations from running in the background.

Examples

  1. Implementing PulseCountDown in Android example code:

    <com.github.jinatonic.confetti.ConfettiView android:id="@+id/confettiView" android:layout_width="match_parent" android:layout_height="match_parent" app:confettiSize="10" app:confettiVelocityX="10" app:confettiVelocityY="10" app:confettiAccelerationX="5" app:confettiAccelerationY="5"/> 
    val confettiView: ConfettiView = findViewById(R.id.confettiView) // Trigger confetti animation confettiView.build() .addColors(Color.YELLOW, Color.GREEN, Color.BLUE) .setDirection(0.0, 359.0) .setSpeed(1f, 5f) .setFadeOutEnabled(true) .setTimeToLive(2000L) .addShapes(Shape.Square, Shape.Circle) .setPosition(-50f, confettiView.width + 50f, -50f, -50f) .streamFor(300, 5000L)
