Android - animate() 在不同屏幕尺寸下的问题

Question

Im having this problem with the animate() in different screen sizes. I was testing everything in my s9+ and when i tested the same on a Moto g3 the layouts that i animated with animate().translationY were a disaster. So i googled a little bit and of course i was doing the things in a wrong way. I found here that i have to use this piece of code:

Float distance = TypedValue.applyDimension(
                TypedValue.COMPLEX_UNIT_DIP, 770,
                getResources().getDisplayMetrics()
        );

(770) is my value.

And then cardViewBottom.animate().translationY(distance).setDuration(1);

But i am not having a good result. In my s9+ 770 is the correct value, and in my moto g3 (smaller device) is 560 the value. I don't know what to do.

Answer 1

Try this:

val metrics = DisplayMetrics()
windowManager?.defaultDisplay?.metrics(metrics)
val width = metrics.density

val distance = TypedValue.applyDimension(
                TypedValue.COMPLEX_UNIT_DIP, width,
                resources.displayMetrics)

Not sure what TypedValue.applyDimension's params are If you need pixels then metrics.widthPixels
