获得view保存成bitmap图片格式

   private Bitmap getBitmapFromView(View view) {        Bitmap bitmap = null;        try {            int width = view.getWidth();            int height = view.getHeight();            if (width != 0 && height != 0) {                bitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);                Canvas canvas = new Canvas(bitmap);                view.layout(0, 0, width, height);                view.draw(canvas);            }        } catch (Exception e) {            bitmap = null;            e.getStackTrace();        }        return bitmap;    }
