### Android获取原始图片Bitmap的宽高大小尺寸，Kotlin ###

###  ###

val options = BitmapFactory.Options()
                        options.inJustDecodeBounds = true
    
                        val decodeBmp = BitmapFactory.decodeResource(resources, R.mipmap.p1, options)
                        //此时，decode出来的decodeBmp宽高并不是原始图的宽高。
                        //options里面的宽高才是原始图片的宽高
                        val bmpWidth = options.outWidth
                        val bmpHeight = options.outHeight
                        Log.d(TAG, "原始图片宽高 ${bmpWidth} ${bmpHeight}")

下面的代码是告诉Android，只解析宽高尺寸，不decode原始图片文件：

val options = BitmapFactory.Options()
                        options.inJustDecodeBounds = true

然后从options里面读原始图片的宽高尺寸。
