Android中将View转为Bitmap

/**
     * 截取View的屏幕
     *
     * @return Bitmap
     */
    public static Bitmap getBitmapByScorw(View viewLayout) {
        Bitmap bmp = Bitmap.createBitmap(viewLayout.getWidth(), viewLayout.getHeight(), Bitmap.Config.ARGB_8888);
        Canvas canvas = new Canvas(bmp);
        canvas.drawColor(Color.WHITE);
        viewLayout.draw(canvas);
        return bmp;
    }

分两种情况
1.需要转为Bitmap的View在屏幕中能完全展示,则正常传递最外层View；
2.需要转为Bitmap的View在屏幕中超出一屏展示,通常为ScrollView包括的布局方式,则需要传递ScrollView的子View来生成图片;
