现在图片列表单张图片宽高默认为200，有的设备，例如平板上显示的时候会很模糊，
是否可以根据设备尺寸动态设置呢？
我给出的方案为：
`val wm = mContext.getSystemService(Context.WINDOW_SERVICE) as WindowManager
if(width == 0){
width = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB_MR2) {
val size = Point()
wm.defaultDisplay.getSize(size)
size.x /4
} else {
wm.defaultDisplay.width / 4
}
}`

这里的 4 表示单行显示的图片个数

Start by locating the Android image-list item sizing entry point and review how the default width and height of 200 are applied. Check the proposed screen-width calculation across API 27–32 and tablet-sized devices, using the demo to verify the result. Done means image dimensions adapt to the screen and the configured four items per row without becoming blurry.
