在目录滚动而不是工具栏上隐藏TabLayout [英] Hide TabLayout on Scroll of Content instead of ToolBar

问题描述

我想在滚动内容时隐藏TabLayout。目前，我搜索了网络，但发现了一些隐藏工具栏的示例，但是我想隐藏TabLayout。所以请帮帮我。我尝试了下面的代码。

I want to hide TabLayout on scrolling my content. Currently I searched the net but I found samples which hide the Toolbar, but I want to hide TabLayout. So please help me. I tried below code.

<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/main_content"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

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

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

        <android.support.design.widget.TabLayout
            android:id="@+id/id_tabs"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize" 
            style="@style/MyCustomTabLayout"/>

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

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

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

以下是示例应用程序：
https://play.google.com/store/apps/details?id=com.contextlogic.wish
https://play.google.com/store/apps/details?id=co。 vine.android

Here is the example applications: https://play.google.com/store/apps/details?id=com.contextlogic.wish https://play.google.com/store/apps/details?id=co.vine.android

推荐答案

尝试这种方法。主要思想是将工具栏移到CoordinatorLayout之外，并将此视图结构与其他容器布局一起包装。

Try this approach. The main idea is to move Toolbar outside the CoordinatorLayout and wrap this view structure with other container layout.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

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

        <android.support.v7.widget.Toolbar
            android:id="@+id/id_toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            app:layout_collapseMode="pin"
            app:layout_scrollFlags="scroll|exitUntilCollapsed" />
    </android.support.design.widget.AppBarLayout>

    <android.support.design.widget.CoordinatorLayout
        android:id="@+id/main_content"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@id/id_toolbar_container">

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

            <android.support.design.widget.CollapsingToolbarLayout
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                app:layout_scrollFlags="scroll|enterAlways">

                <android.support.design.widget.TabLayout
                    android:id="@+id/id_tabs"
                    android:layout_width="match_parent"
                    android:layout_height="?attr/actionBarSize" />
            </android.support.design.widget.CollapsingToolbarLayout>

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

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

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