防止状态栏显示在具有 Notch 的设备中的 NavigationView 上

Question

I have an issue with my NavigationView , when it's expanded the statusBar is shown in semitransparent color over it and i would hide it completely by still keeping notch support.

It looks like this now:

I've tried to add

android:fitsSystemWindows="false" in my Activity but nothing chanded.

My styles.xml looks like this:

    <style name="AppTheme" parent="Theme.MaterialComponents.Light.NoActionBar.Bridge">
        <item name="android:windowNoTitle">true</item>
        <item name="android:windowActionBar">false</item>
        <item name="android:windowFullscreen">true</item>
        <item name="android:windowContentOverlay">@null</item>
        <item name="colorAccent">@color/colorAccent</item>
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorAccent</item>
        <item name="primaryTextColor">#F4F4F6</item>
        <item name="colorControlNormal">@color/colorAccent</item>
        <item name="secondaryTextColor">#96000000</item>
        <item name="recyclerViewTitleColor">#96000000</item>
        <item name="navColor">#2948ff</item>
        <item name="colorTurni">@color/blueLight</item>
        <item name="varianti">@color/green</item>
        <item name="blueDark">@color/blueDark</item>
        <item name="backgroundCardColor">#FFFF</item>
        <item name="bottomSheetDialogTheme">@style/ThemeOverlay.App.BottomSheetDialog</item>
        <item name="android:windowLayoutInDisplayCutoutMode">
            shortEdges
        </item>
        <item name="android:windowTranslucentStatus">true</item>
    </style>
</resources>

What i would reach is this:

Activity.xml

<androidx.drawerlayout.widget.DrawerLayout android:id="@+id/drawer_layout"
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"

    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#FAFAFA"
    android:orientation="vertical"
    tools:context="it.gabtamagnini.visualposmobile.PtermActivity">


    <androidx.coordinatorlayout.widget.CoordinatorLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

    ...

    </androidx.coordinatorlayout.widget.CoordinatorLayout>

    <com.google.android.material.navigation.NavigationView
        android:id="@+id/nav_menu"
        android:layout_width="185dp"
        android:layout_height="match_parent"
        android:fitsSystemWindows="false"
        android:background="@color/white"
        android:layout_gravity="start"
        app:headerLayout="@layout/layout_header">

        <androidx.recyclerview.widget.RecyclerView
            android:id="@+id/recyclerViewMenu"
            android:layout_width="match_parent"
            android:layout_marginTop="120dp"
            android:layout_height="match_parent"
            tools:listitem="@layout/layout_menu"
            android:clipToPadding="false"
            android:paddingBottom="15dp"
            android:paddingEnd="5dp"
            android:paddingStart="5dp" />

    </com.google.android.material.navigation.NavigationView>

</androidx.drawerlayout.widget.DrawerLayout>

Answer 1

Cause:

This shadow is related to the drawable used for the inset foreground which is customized to R.styleable.ScrimInsetsFrameLayout_insetForeground style by default on the NavigationView ; this answer explains more about the ScrimInsetsFrameLayout class.

Solution:

Getting rid of this drawable from the NavigationView either programmatically or in layout:

Programmatically: setting setScrimInsetForeground to null.

navView.setScrimInsetForeground(null)

In layout: using app:insetForeground="@null" :

<com.google.android.material.navigation.NavigationView
    android:id="@+id/nav_menu"
    ....
    app:insetForeground="@null"/>
