Android9.0 PopupWindow 适配刘海屏，水滴屏等

现象：弹出PopupWindow选项框后，刘海屏或水滴屏不能到顶。

改进后代码：

     popupWindow = PopupWindow(view, ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT, true).apply {
            setBackgroundDrawable(ColorDrawable(Color.TRANSPARENT))
            contentView.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_STABLE or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
            if (Build.VERSION.SDK_INT == Build.VERSION_CODES.M || Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
                isClippingEnabled = false
            }
            animationStyle = R.style.FadeInAnimation
        }

如果是9.0及以上就不允许裁剪。

styles.xml文件：

    <style name="FadeInAnimation">
        <item name="android:activityOpenEnterAnimation">@anim/fade_in</item>
        <item name="android:activityOpenExitAnimation">@anim/fade_out</item>
        <item name="android:activityCloseEnterAnimation">@anim/fade_in</item>
        <item name="android:activityCloseExitAnimation">@anim/fade_out</item>
        <item name="android:fragmentOpenEnterAnimation">@anim/fade_in</item>
        <item name="android:fragmentOpenExitAnimation">@anim/fade_out</item>
        <item name="android:fragmentCloseEnterAnimation">@anim/fade_in</item>
        <item name="android:fragmentCloseExitAnimation">@anim/fade_out</item>
    </style>

fade_in.xml:

<?xml version="1.0" encoding="utf-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
       android:duration="250"
       android:fromAlpha="0.5"
       android:interpolator="@android:interpolator/accelerate_decelerate"
       android:toAlpha="1"/>

fade_out.xml:

<?xml version="1.0" encoding="utf-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
       android:duration="250"
       android:fromAlpha="1"
       android:interpolator="@android:interpolator/accelerate_decelerate"
       android:toAlpha="0.5"/>

如果出现内容尺寸异常，则设置其宽高。

 isClippingEnabled = false
 val lp = ViewGroup.LayoutParams(width, height)
 view.setLayoutParams(lp)

view为布局

activity适配刘海屏

     if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
            val lp = window.attributes
            lp.layoutInDisplayCutoutMode = WindowManager.LayoutParams.LAYOUT_IN_DISPLAY_CUTOUT_MODE_SHORT_EDGES
            window.attributes = lp
        }
