Android 如何在listview中平滑滚动时隐藏工具栏以及I'；我也在使用底部导航

我正在开发一个显示新闻的应用程序，我想在列表视图中滚动时隐藏工具栏，我通过coordinatorLayout尝试了它，但由于底部导航无法工作，有人能帮我吗

我的XML代码：

<LinearLayout 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"
android:orientation="vertical"
tools:context="wahwah.ahmed.google.waheed.app.ninews.android.com.ninewsapp.MainActivity">

<android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/AppTheme.AppBarOverlay">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:popupTheme="@style/AppTheme.PopupOverlay" />

    <android.support.design.widget.TabLayout
        android:id="@+id/tabs"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:tabMode="scrollable" />

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


<FrameLayout
    android:id="@+id/content"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1">

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

    <View
        android:id="@+id/gradientShadow"
        android:layout_width="match_parent"
        android:layout_height="7dp"
        android:background="@drawable/dropshadow"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"
        app:layout_collapseMode="pin"/>

</FrameLayout>

<android.support.design.widget.BottomNavigationView
    android:id="@+id/navigation"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom"
    android:background="?android:attr/windowBackground"
    app:menu="@menu/navigation" />

</LinearLayout>

我需要有人帮我修复它。

为了实现此功能，实际上不需要折叠工具栏布局，您只需折叠设置为操作栏的工具栏即可

下面是一个示例代码，它使用一个将折叠的ActionBar工具栏和一个带有ViewPager的TableLayout

首先确保MainActivity使用的样式没有ActionBar，例如：

<style name="AppTheme" parent="@style/Theme.AppCompat.Light.NoActionBar">
    <!-- ....... -->
</style>

自定义选项卡.xml：

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent">
    <TextView
        android:id="@+id/custom_text"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:background="?attr/selectableItemBackground"
        android:gravity="center"
        android:textSize="16dip"
        android:textColor="#ffffff"
        android:singleLine="true"
        />
</LinearLayout>

fragment_blank.xml，使用RecyclerView或任何其他支持嵌套滚动的视图（如

（旁注：您可以调用api-21及更高版本，使其与ListView一起工作）：

build.gradle依赖项：

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:23.0.1'
    compile 'com.android.support:design:23.0.1'
    compile 'com.android.support:cardview-v7:23.0.1'
    compile 'com.android.support:recyclerview-v7:23.0.1'
}

结果:

更新

您可以像这样添加BottomNavigationView

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1">


        <android.support.design.widget.AppBarLayout
            android:id="@+id/appBarLayout"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:elevation="6dp">

            <android.support.v7.widget.Toolbar
                android:id="@+id/toolbar"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_alignParentTop="true"
                android:background="@color/colorPrimary"
                android:minHeight="?attr/actionBarSize"
                android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
                app:elevation="0dp"
                app:layout_scrollFlags="scroll|enterAlways"
                app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />

            <android.support.design.widget.TabLayout
                android:id="@+id/tab_layout"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_below="@+id/toolbar"
                android:background="@color/colorPrimary"
                android:minHeight="?attr/actionBarSize"
                app:elevation="0dp"
                app:tabIndicatorColor="#ff00ff"
                app:tabMode="fixed"
                app:tabSelectedTextColor="#ffffff"
                app:tabTextColor="#d3d3d3" />

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

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

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

    <android.support.design.widget.BottomNavigationView
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />
</LinearLayout>

您可能会从查看和确认中受益，但问题是我也想添加底部导航，因此应用程序应该包含工具栏、tabLayout和导航底部，当我滚动工具栏时，您是否注意到

app:layout\u scrollFlags=“scroll | enteravely”

和

tabMode=“fixed”

。您将向tabLayout添加scrollFlags并删除固定的tabmode。这对我不起作用，您能用所需的更改编辑我的代码吗？好的，我会更改，告诉我您希望滚动时listView保留所有其他内容，而toolbar、tabLayout和bottomNavigationView隐藏？我希望滚动时工具栏隐藏，其他内容保留（表格布局、底部导航、列表视图）
