我的活动包含以下元素:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    tools:showIn="@layout/activity_game"
    android:keepScreenOn="true">

    <SurfaceView
        android:id="@+id/scan_surface"
        android:layout_width="match_parent"
        android:layout_height="300px"
        android:layout_alignParentStart="true"
        android:layout_alignParentTop="true">

    </SurfaceView>

    <TextView
        android:id="@+id/qr_code_result"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="TextView" />

    <WebView
        android:id="@+id/webview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_alignParentStart="true"
        android:layout_alignParentTop="true"
        android:visibility="visible" />
</RelativeLayout>

在我的onResume中,我执行以下操作:

        super.onResume();

        View decorView = getWindow().getDecorView();
        decorView.setSystemUiVisibility(
                View.SYSTEM_UI_FLAG_IMMERSIVE
                // Set the content to appear under the system bars so that the
                // content doesn't resize when the system bars hide and show.
                | View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                // Hide the nav bar and status bar
                | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                | View.SYSTEM_UI_FLAG_FULLSCREEN);

但是,如果用户从屏幕的顶部边缘滑动以显示状态栏和通知,则即使在Web视图中点击状态栏也不会消失。我究竟做错了什么?已在Android 7和8上观察到(并非唯一)。

主题设置为android:theme="@style/AppTheme.NoActionBar"compileSdkVersion为26。
