LottieDrawable set bounds not working

[zhangruize]

For some special reasons, I need to use LottieDrawable like View.getOverlay().add(lottieDrawable). But I found the animation content cannot be positioned in center though I set correct bounds via lottieDrawable.setBounds(...) after lottie composition loaded.

Is there any way to center LottieDrawable in View.getOverlay() ?

I've found a not quite good solution. I override draw method of LottieDrawable, and translate the canvas as I want. Is there any better idea?

I'm not using the latest version of Lottie. If the latest have support this perfectly, it's ok, if not, maybe LottieDrawable should support something like translate the canvas of animation content.

@zhangruize Can you attach a sample project?

I think translating for your specific use case is fine. Most of the time, ImageView scaleType is what you would use to achieve this.

I'm also trying to setBounds on LottieDrawable, but it's not working.
When I scale LottieDrawable with setScale(), it setBounds to (0,0,width,height)
but I want to set animation on the bottom-right corner of the drawable. And This work is not UI
related, So I can't set scaleType on LottieAnimationView. Please tell me how can scale drawable to stay at the bottom-right corner.

I'm facing same issue with View.getOverlay().add(lottieDrawable).
Calling LottieDrawable.setBounds(x, y, width, height) does not affect. The animation always appears left top corner of View Overlay.

my workaround, same approach as @zhangruize

class PositionedLottieDrawable : LottieDrawable() {
    var x: Float = 0f
    var y: Float = 0f
    override fun draw(canvas: Canvas) {
        canvas.save()
        canvas.translate(x, y)
        super.draw(canvas)
        canvas.restore()
    }
}

@Krishna-Vyas @irgaly What version of Lottie? 3.6.0 should respect the bounds you set

[irgaly]

I'm using 3.4.0.

I tried Lottie 3.6.1, but the animation appeared at (0, 0).
Here is my code, and I tested it in Android 9.

private val drawable = LottieDrawable()
...
// I watched with debugger, they are x = 792, y = 161 here. 
drawable.setBounds(x, y, drawable.composition.bounds.right + x, drawable.composition.bounds.bottom + y)
targetView.overlay.add(drawable)
drawable.playAnimation()
