Android 11 PopupWindow 內(nèi)容區(qū)域會(huì)被 導(dǎo)航欄 遮擋，可以利用 FLAG_LAYOUT_IN_SCREEN 的 Flag 進(jìn)行校正，如下：

private fun setLayoutInScreenEnabled(popup: PopupWindow) {
  // 修復(fù)安卓11導(dǎo)航欄遮擋問題
  if (Build.VERSION.SDK_INT > BUILD_VERSION_CODE_Q) {
    val wm = context.getSystemService(Context.WINDOW_SERVICE) as? WindowManager
    var viewContent = popup.contentView
    while (viewContent != null && viewContent.layoutParams !is WindowManager.LayoutParams) {
      viewContent = viewContent.parent as? View
    }
    if (viewContent?.layoutParams is WindowManager.LayoutParams) {
      val params = viewContent.layoutParams as WindowManager.LayoutParams
      params.flags = params.flags or WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN
      wm?.updateViewLayout(viewContent, params)
    }
  }
}
