これ、おもしろい!!

ちょっと画像をお借りして、

やってみましたが、、、

@Composable
fun Humans() {
  var currentRotation by remember { mutableFloatStateOf(0f) }
  val rotation = remember { Animatable(currentRotation) }

  LaunchedEffect(Unit) {
    rotation.animateTo(
      targetValue = currentRotation + 360f,
      animationSpec = infiniteRepeatable(
        animation = tween(3000, easing = LinearEasing),
        repeatMode = RepeatMode.Restart
      )
    ) {
      currentRotation = rotation.value
    }
  }
  Image(
    modifier = Modifier
      .fillMaxSize()
      .rotate(rotation.value)
      .aspectRatio(1.0f),
    painter = painterResource(R.drawable.humans),
    contentDescription = null
  )
}

ダメでした。。。

なんで、おじさんが走ってくれないのでしょうかー。

なんとなくまだ古くさい感じはありますが。

val context = LocalContext.current

fun Context.getActivityOrNull(): Activity? {
    var context = this
    while (context is ContextWrapper) {
        if (context is Activity) return context
        context = context.baseContext
    }    
    return null
}

fun Context.findActivity(): Activity {
    var context = this
    while (context is ContextWrapper) {
        if (context is Activity) return context
        context = context.baseContext
    }
    throw IllegalStateException("Permissions should be called in the context of an Activity")
}
