android - getSize() 在 API 级别 30 中已弃用

Question

我使用 getSize() 方法来获取屏幕尺寸:

override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
    val fragmentActivity = requireActivity()
    ...
    val wm = fragmentActivity.getSystemService(Context.WINDOW_SERVICE) as WindowManager 
    val display = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
        fragmentActivity.display
    } else {
        wm.defaultDisplay 
    }
    val size = Point()
    display?.getSize(size)
    
    // get screen sizes
    val width = size.x
    val height = size.y
    ...
}

但是在 API 级别 30 中，声明方法 getSize() 已弃用。
可以使用什么代替 getSize() 来获取屏幕尺寸？
感谢您的任何评论/回答!
解决方案 :

val wm = fragmentActivity.getSystemService(Context.WINDOW_SERVICE) as WindowManager
val width: Int
val height: Int
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
    val windowMetrics = wm.currentWindowMetrics
    val windowInsets: WindowInsets = windowMetrics.windowInsets

    val insets = windowInsets.getInsetsIgnoringVisibility(
          WindowInsets.Type.navigationBars() or WindowInsets.Type.displayCutout())
    val insetsWidth = insets.right + insets.left
    val insetsHeight = insets.top + insets.bottom

    val b = windowMetrics.bounds
    width = b.width() - insetsWidth
    height = b.height() - insetsHeight
} else {
    val size = Point()
    val display = wm.defaultDisplay // deprecated in API 30
    display?.getSize(size) // deprecated in API 30
    width = size.x
    height = size.y
}

如果像我一样，您只想获取窗口大小，这里有一个兼容版本:

fun WindowManager.currentWindowMetricsPointCompat(): Point {
    return if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.R) {
        val windowInsets = currentWindowMetrics.windowInsets
        var insets: Insets = windowInsets.getInsets(WindowInsets.Type.navigationBars())
        windowInsets.displayCutout?.run {
            insets = Insets.max(insets, Insets.of(safeInsetLeft, safeInsetTop, safeInsetRight, safeInsetBottom))
        }
        val insetsWidth = insets.right + insets.left
        val insetsHeight = insets.top + insets.bottom
        Point(currentWindowMetrics.bounds.width() - insetsWidth, currentWindowMetrics.bounds.height() - insetsHeight)
    }else{
        Point().apply {
            defaultDisplay.getSize(this)
        }
    }
}

它将负责删除导航栏的插图并显示剪切区域以在两种情况下获得相同的结果
