如何在浮动操作按钮上方放置透明布局
how to put a transparent layout above floating action button
我正在开发一个应用程序，我想在整个屏幕上放置一个透明视图，我在这方面取得了一定的成功，但我的屏幕也包含浮动操作按钮
我无法将透明布局放在浮动操作按钮上方
这是我的xml

我曾尝试通过提升来解决此问题，但未能实现
任何人都可以建议我将布局放在浮动操作按钮上方的方法
在 FAB 之后定义透明布局。像这样 -
<android.support.design.widget.FloatingActionButton
android:id="@+id/like_img"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="80dp"
android:background="@color/white"
android:elevation="10dp"
android:src="@drawable/like"
app:fabSize="normal"
app:layout_anchor="@id/app_bar"
app:layout_anchorGravity="bottom|center_vertical" />
<android.support.design.widget.FloatingActionButton
android:id="@+id/fav_img"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:elevation="10dp"
android:src="@drawable/add_to_stylebook"
app:fabSize="normal"
app:layout_anchor="@id/app_bar"
app:layout_anchorGravity="bottom|center" />
<android.support.design.widget.FloatingActionButton
android:id="@+id/share_img"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="70dp"
android:elevation="10dp"
android:src="@drawable/share"
app:fabSize="normal"
app:layout_anchor="@id/app_bar"
app:layout_anchorGravity="bottom|right" />
<View
android:id="@+id/tranparent_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/grey_very_light_semi_transparent"
android:elevation="15dp"
android:fitsSystemWindows="true"
android:visibility="gone" />
Android 布局是按 Z 顺序排列的，即，一个接一个定义的布局将在视觉上位于它之上。在包含 FAB 的容器之后添加您的透明视图，这样您的透明视图将位于 FAB 之上并有效地绘制在它上面。
在透明视图中添加此行：
android:translationZ="8dp"
我正在开发一个应用程序，我想在整个屏幕上放置一个透明视图，我在这方面取得了一定的成功，但我的屏幕也包含浮动操作按钮
我无法将透明布局放在浮动操作按钮上方
这是我的xml

我曾尝试通过提升来解决此问题，但未能实现
任何人都可以建议我将布局放在浮动操作按钮上方的方法
在 FAB 之后定义透明布局。像这样 -
<android.support.design.widget.FloatingActionButton
android:id="@+id/like_img"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="80dp"
android:background="@color/white"
android:elevation="10dp"
android:src="@drawable/like"
app:fabSize="normal"
app:layout_anchor="@id/app_bar"
app:layout_anchorGravity="bottom|center_vertical" />
<android.support.design.widget.FloatingActionButton
android:id="@+id/fav_img"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:elevation="10dp"
android:src="@drawable/add_to_stylebook"
app:fabSize="normal"
app:layout_anchor="@id/app_bar"
app:layout_anchorGravity="bottom|center" />
<android.support.design.widget.FloatingActionButton
android:id="@+id/share_img"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="70dp"
android:elevation="10dp"
android:src="@drawable/share"
app:fabSize="normal"
app:layout_anchor="@id/app_bar"
app:layout_anchorGravity="bottom|right" />
<View
android:id="@+id/tranparent_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/grey_very_light_semi_transparent"
android:elevation="15dp"
android:fitsSystemWindows="true"
android:visibility="gone" />
Android 布局是按 Z 顺序排列的，即，一个接一个定义的布局将在视觉上位于它之上。在包含 FAB 的容器之后添加您的透明视图，这样您的透明视图将位于 FAB 之上并有效地绘制在它上面。
在透明视图中添加此行：
android:translationZ="8dp"
