android - 我试图弄清楚如何在导航抽屉中单击FAB菜单时添加暗淡的背景

我在导航抽屉中有FAB菜单。我使用的是android.support.design.widget.FloatingActionButton按钮，此按钮的onclick显示了四个弧形的FAB。我在导航抽屉中有一个容器，该容器会不断替换抽屉中的片段（抽屉的正常行为）。当用户单击FAB菜单按钮时，如何禁用背景。不过，我对如何完成此操作有些困惑。

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:gravity="center"
    android:layout_width="match_parent"
    android:layout_height="match_parent">


 <FrameLayout
        android:layout_below="@id/toolbar"
        android:id="@+id/frame_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/white"
        >
        <RelativeLayout
            android:id="@+id/obstructor"
            android:visibility="invisible"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:alpha="1000"
            android:background="@android:color/black">
</RelativeLayout>

        <android.support.design.widget.FloatingActionButton
        android:id="@+id/home"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_alignBottom="@id/frame_container"
        android:layout_gravity="bottom|right"
        android:layout_marginRight="10dp"
        android:layout_marginBottom="6dp"
        app:fabSize="normal"
        android:src="@drawable/ic_action_navigation_close_inverted"
        app:backgroundTint="@android:color/holo_red_dark"
        app:rippleColor="#F06292">
</android.support.design.widget.FloatingActionButton>
    </FrameLayout>
   </RelativeLayout>

最佳答案

您不能通过设置标志来设置它，该标志需要为FAB按钮的背面添加虚拟布局并在单击FAB时使其可单击

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:gravity="center"
    android:layout_width="match_parent"
    android:layout_height="match_parent">


 <FrameLayout
        android:layout_below="@id/toolbar"
        android:id="@+id/frame_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/white"
        >
        <RelativeLayout
            android:id="@+id/obstructor"
            android:visibility="invisible"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:alpha="1000"
            android:background="@android:color/black">
</RelativeLayout>
 <LinearLayout
    android:id="@+id/llRoot"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

    android:clickable="false"
    android:orientation="vertical" />
        <android.support.design.widget.FloatingActionButton
        android:id="@+id/home"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_alignBottom="@id/frame_container"
        android:layout_gravity="bottom|right"
        android:layout_marginRight="10dp"
        android:layout_marginBottom="6dp"
        app:fabSize="normal"
        android:src="@drawable/ic_action_navigation_close_inverted"
        app:backgroundTint="@android:color/holo_red_dark"
        app:rippleColor="#F06292">
</android.support.design.widget.FloatingActionButton>
    </FrameLayout>
