1.先導入函示庫(build.gradle: Module)

dependencies {
   implementation 'com.dinuscxj:circleprogressbar:1.3.6'
}

2.程式碼範例

a.Layout

<com.dinuscxj.progressbar.CircleProgressBar
    android:id="@+id/circle_bar"
    android:layout_width="50dp"
    android:layout_height="50dp"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent" />

b.設置動畫

val animator = ValueAnimator.ofInt(0, 101)
animator.addUpdateListener {
    val progress = it.animatedValue as Int
    circle_bar.progress = progress
}
animator.repeatCount = ValueAnimator.INFINITE
animator.duration = 4000
animator.start()

3.效果展示
