我的应用程序包含一个带有工具栏,线性布局和Tabllayout的片段。我已启用工具栏的滚动标记。现在,当我尝试在tablayout中的recyclerview中滚动时,工具栏并没有阻碍。当我手动按下TabLayout时,它开始移动并能够隐藏或显示。以下是我正在使用的布局。怎么了

主要布局:

<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/coordinatorLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">



<android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
    android:id="@+id/app">

<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:background="@color/textcolor"
    android:layout_height="?attr/actionBarSize"
    app:layout_scrollFlags="scroll|enterAlways">

    <Button
        android:id="@+id/back"
        android:layout_width="24dp"
        android:layout_height="24dp"
        android:layout_gravity="start"
        android:layout_marginRight="5dp"
        android:layout_marginEnd="5dp"
        android:background="@drawable/backblack" />


</android.support.v7.widget.Toolbar>

<LinearLayout
        android:id="@+id/layloc"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/toolbar"
        android:orientation="horizontal"
        android:weightSum="1"
        android:padding="5dp"
        android:background="@drawable/border"
    android:visibility="gone">


        <TextView
            android:id="@+id/locationname"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:drawableStart="@drawable/location"
            android:drawableLeft="@drawable/location"
            android:drawablePadding="3dp"
            android:layout_weight="1"
            android:layout_gravity="center_horizontal"
            android:textColor="@color/cblack"
            android:text="fetching current location"
            android:textAppearance="@style/Base.TextAppearance.AppCompat.Medium.Inverse"/>

        <TextView
            android:id="@+id/change"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center_horizontal"
            android:text="Change"
            android:drawablePadding="3dp"
            android:textColor="@color/cblack"
            android:textAppearance="@style/Base.TextAppearance.AppCompat.Medium"/>

    </LinearLayout>


<android.support.design.widget.TabLayout
    android:id="@+id/tab_layout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_below="@+id/layloc"
    android:background="@color/textcolor"
    app:tabTextColor="@color/black"
    app:tabPaddingStart="0dp"
    app:tabPaddingEnd="0dp"
    app:tabIndicatorHeight="2dp" />

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



<android.support.v4.view.ViewPager
    android:id="@+id/pager"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"/>


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

片段布局:

<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/textcolor"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
android:id="@+id/mainexplore">


<android.support.v7.widget.RecyclerView
    android:id="@+id/lists"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:divider="@drawable/list_divider"
    android:dividerHeight="1px"
    android:scrollbars="none"
    android:visibility="gone"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"/>

<TextView
    android:id="@+id/emptyElement"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerInParent="true"
    android:text="@string/nofoodfound"
    android:textColor="@color/button"
    android:visibility="gone"/>

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

我尝试使用不同的滚动标志,但是问题是相同的。我在SO中已经看到了示例和一些与此类似的问题,但是它们都没有回答我的查询。工具栏可以隐藏,但需要手动按下。布局有什么问题。此布局中缺少什么。

您需要从appBarLayout中删除按钮视图。检查我的。

<android.support.design.widget.CoordinatorLayout

xmlns:app="http://schemas.android.com/apk/res-auto"

android:layout_height="match_parent"
android:id="@+id/coordinator_layout"

<android.support.design.widget.AppBarLayout
    android:id="@+id/appBar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <android.support.v7.widget.Toolbar
        android:id="@+id/tool_bar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:minHeight="?attr/actionBarSize"
        android:elevation="5dp"
        android:theme="@style/ToolbarTheme"
        app:layout_scrollFlags="scroll|enterAlways"
        app:titleTextAppearance="@style/Toolbar.TitleText"
        />
