Question

我使用CoordinatorLayout和CollapsingToolbarLayout，我不知道是什么导致这个错误，这是我的xml文件

toolbar.xml用于工具栏视图

    android:layout_height="wrap_content"
    android:fitsSystemWindows="true">

    <android.support.design.widget.CollapsingToolbarLayout
        android:id="@+id/collapsing_toolbar"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fitsSystemWindows="true"
        app:contentScrim="@color/actionbar"

            app:layout_scrollFlags="scroll|enterAlways" />

    </android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>

Answer 1

从AppBarLayout中删除android：fitsSystemWindows =“true”，你很高兴。启用后，AppBarLayout会假定状态栏不可用，并且必须占用整个房地产。

Answer 2

只需在下面的LinearLayout中插入工具栏布局和框架布局。

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <include layout="@layout/toolbar"/>

    <FrameLayout
        android:id="@+id/fragment_container"
        android:layout_width="fill_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"/>
</LinearLayout>

这可能对你有所帮助。

当我想在CollapsingToolbarLayout中加载ImageView时，我遇到了同样的问题，经过一些研究后我发现了如下解决方案：

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout 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:id="@+id/coordinator_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:windowDrawsSystemBarBackgrounds="true"
tools:context="com.example.k1.DetailActivity">

<android.support.design.widget.AppBarLayout
    android:id="@+id/detail_app_bar"
    android:layout_width="match_parent"
    android:layout_height="@dimen/app_bar_height"
    android:fitsSystemWindows="true"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

    <android.support.design.widget.CollapsingToolbarLayout
        android:id="@+id/collapsing_toolbar_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fitsSystemWindows="true"
        app:collapsedTitleTextAppearance="@android:style/TextAppearance.Material.Small"
        app:contentScrim="?attr/colorPrimary"
        app:expandedTitleTextAppearance="@android:color/transparent"
        app:layout_scrollFlags="scroll|exitUntilCollapsed"
        tools:targetApi="lollipop">


        <ImageView
            android:id="@+id/detail_sliding_view_pager"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_gravity="fill|center"
            android:fitsSystemWindows="true"
            app:layout_collapseMode="parallax" />

        <android.support.v7.widget.Toolbar
            android:id="@+id/detail_toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:minHeight="?attr/actionBarSize"
            app:contentScrim="?attr/colorPrimary"
            app:layout_collapseMode="pin"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
            app:statusBarScrim="?attr/colorAccent" />

    </android.support.design.widget.CollapsingToolbarLayout>

</android.support.design.widget.AppBarLayout>

注意：AppBarLayout高度值在维度资源值中设置为android:layout_height="@dimen/app_bar_height"，通过300dp为xxhdpi设置为<dimen name="app_bar_height">300dp</dimen>。 我希望这可以帮助你。

只需删除android：fitsSystemWindows =“true”，因为当它为true时，它将调整AppbarLayout的填充以为状态栏留出空间。
