Adapt Android screens to phones with various aspect ratios

Because there are too many screen aspect ratio styles for android phones, when designing UI, many times, there will be differences in display due to different aspect ratios and resolutions.

I solved it like this

Before the activity's onCreate method, call:

 

 fun screenFit(context: Context) {
        val metrics: DisplayMetrics = context.resources.displayMetrics
        val td = metrics.heightPixels / 760f
        val dpi = (160 * td).toInt()
        metrics.density = td
        metrics.scaledDensity = td
        metrics.densityDpi = dpi
    }

so it fits
