view.getDrawingCache() is deprecated in Android API 28

Two ways to get bitmap of view

1. Using Canvas
2. Using Pixel Api

Canvas Java

public Bitmap getBitmapFromView(View view){    Bitmap bitmap = Bitmap.createBitmap(view.getWidth(), view.getHeight(), Bitmap.Config.ARGB_8888);    Canvas canvas = new Canvas(bitmap);    view.draw(canvas);    return bitmap;}public Bitmap getBitmapFromView(View view,int defaultColor){    Bitmap bitmap = Bitmap.createBitmap(view.getWidth(), view.getHeight(), Bitmap.Config.ARGB_8888);    Canvas canvas = new Canvas(bitmap);    canvas.drawColor(defaultColor);    view.draw(canvas);    return bitmap;}

Canvas Kotlin

open fun getBitmapFromView(view: View): Bitmap? {    var bitmap =        Bitmap.createBitmap(view.width, view.height, Bitmap.Config.ARGB_8888)    var canvas = Canvas(bitmap)    view.draw(canvas)    return bitmap}open fun getBitmapFromView(view: View, defaultColor: Int): Bitmap? {    var bitmap =        Bitmap.createBitmap(view.width, view.height, Bitmap.Config.ARGB_8888)    var canvas = Canvas(bitmap)    canvas.drawColor(defaultColor)    view.draw(canvas)    return bitmap}

Example

//@param rootView is View object which you want to get bitmapBitmap bitmap = getBitmapFromView(rootView);Bitmap bitmapColored = getBitmapFromView(rootView,Color.WHITE);

PixelCopy Api

https://stackoverflow.com/a/52985554/9909365

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()        }    }}

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()        }    }}

As of the official documentation getDrawingCache() you should use the PixelCopy api.
