当配置文件活动显示时，导航抽屉工具栏不显示

Question

我的问题是我的导航抽屉工具栏隐藏在配置文件活动的装饰后面。我浏览了这样的问题，我得到的唯一可能的解决方案是将约束布局更改为线性布局，但如果没有约束，我不知道倒置的弯曲矩形将如何保持。请帮忙！ 配置文件活动.xml `

您可以尝试将整个布局包装在 CoordinatorLayout 中，并使用 AppBarLayout 创建工具栏，如下所示，并在活动文件中的 onCreate 上访问它，如下所示 -

工具栏工具栏 = findViewById(R.id.toolbar); setSupportActionBar(工具栏);

<androidx.coordinatorlayout.widget.CoordinatorLayout

    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#E1E1E1"
    android:backgroundTint="#E1E1E1"
    tools:context=".ProfileActivity">

    <com.google.android.material.appbar.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <androidx.appcompat.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"

        </androidx.appcompat.widget.Toolbar>

    </com.google.android.material.appbar.AppBarLayout>

    <androidx.core.widget.NestedScrollView
