view.getDrawingCache() is deprecated in Android API 28

Question

In android API 28 view.getDrawingCache() has been deprecated. Is there any newer solution to generate a Bitmap of a particular view in android.

Answer 1

I have found a way to use PixelCopy API for retrieving the view as a Bitmap. Used Kotlin

fun getBitmapFromView(view: View, activity: Activity, callback: (Bitmap) -> Unit) {
    activity.window?.let { window ->
        val bitmap = Bitmap.createBitmap(view.width, view.height, Bitmap.Config.ARGB_8888)
        val locationOfViewInWindow = IntArray(2)
        view.getLocationInWindow(locationOfViewInWindow)
        try {
            PixelCopy.request(window, Rect(locationOfViewInWindow[0], locationOfViewInWindow[1], locationOfViewInWindow[0] + view.width, locationOfViewInWindow[1] + view.height), bitmap, { copyResult ->
                if (copyResult == PixelCopy.SUCCESS) {
                    callback(bitmap)
                }
                // possible to handle other result codes ...
            }, Handler())
        } catch (e: IllegalArgumentException) {
            // PixelCopy may throw IllegalArgumentException, make sure to handle it
            e.printStackTrace()
        }
    }
}
