LinearLayout 可见性不 'GONE' 并且在 android 4.4.4 上也不显示
LinearLayout visibility not 'GONE' and also doesn't show on android 4.4.4
我使用 LinearLayout 作为 "skrim" 来覆盖按下浮动操作按钮后的布局，我将其设置为 alpha 设置为 .55 的颜色，并且它覆盖整个父级。在我的布局中，我将 LinearLayout 设置为 "gone" 然后在我的 kotlin 中，当 FAB 被感动了。
出于某种原因，LinearLayout 根本不会在 apk19 4.4.4 上显示，但它始终存在，这意味着您无法按迷你工厂的和。您可以按主 FAB，但别无他法。我有一个 setOnClickListener 用于 LinearLayout，所以我知道它被按下了，而不是迷你 FAB 的
这是“线性布局”：
<LinearLayout
android:id="@+id/main_profile_overlay"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:alpha="0.55"
android:foreground="@color/profile"
android:orientation="vertical"
android:visibility="gone" />
这里是 Kotlin 实用地改变 LinearLayout:
view.main_profile_overlay.visibility = View.GONE
和
view.main_profile_overlay.visibility = View.VISIBLE
为什么使用 GONE 布局不会消失，为什么不显示颜色和 alpha？
