Fragment 的工具栏上方出现奇怪的空白 space。如何解决？

Question

我正在编写一个 Android 应用程序，它是基于片段的，片段被插入到根空 activity 中。对于每个片段，我都配置了单独的工具栏。当我打开第一个 screen-fragment 时，它工作正常。本画面xml、工具栏代码及截图

                android:id="@+id/toolbar_main"

                android:scrollbars="vertical"

    </LinearLayout>

    <android.support.design.widget.FloatingActionButton

<android.support.design.widget.NavigationView
        android:id="@+id/nav_view"

        app:itemTextAppearance="@style/NavDrawerItem"
        app:headerLayout="@layout/nav_header"/>
</android.support.v4.widget.DrawerLayout>

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
    super.onViewCreated(view, savedInstanceState)
    initToolbar(view)
}

private fun initToolbar(view: View) {
    val toolbar = view.findViewById<Toolbar>(R.id.toolbar_main)
    (activity as AppCompatActivity).setSupportActionBar(toolbar)
    val actionbar: ActionBar? = (activity as AppCompatActivity).supportActionBar
    actionbar?.apply {
        setHasOptionsMenu(true)
        setDisplayHomeAsUpEnabled(true)
        setHomeAsUpIndicator(R.drawable.ic_baseline_menu_white_24)
        title = getString(R.string.app_name)
    }
}

然后当我按下 FAB 打开下一个 Fragment 时。此屏幕的屏幕截图和代码：

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
    super.onViewCreated(view, savedInstanceState)
    initToolbar(view)
}

private fun initToolbar(view: View) {
    val toolbar = view.findViewById<Toolbar>(R.id.toolbar_add_contact)
    (activity as AppCompatActivity).setSupportActionBar(toolbar)
    val actionbar: ActionBar? = (activity as AppCompatActivity).supportActionBar
    actionbar?.apply {
        setHasOptionsMenu(true)
        setDisplayHomeAsUpEnabled(true)
    }
}

正如您在第二个屏幕上看到的，工具栏上方有一个奇怪的 space。所以这是我的问题，我不知道如何解决。请说明如何解决它。

P.S add_contact_toolbar

的布局

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

    tools:menu="@menu/menu_add_contact_screen"/>

Answer 1

这可能与 "android:fitsSystemWindows="true" 的使用有关，因为您的布局考虑了状态栏的高度。尝试摆弄该值。
