包含选项卡和视图页的可折叠工具栏不能被包含列表视图的视图页程序片段折叠



我的布局包含一个可折叠的工具栏、一个选项卡和一个视图寻呼机...我将列表视图包装在嵌套滚动视图中,但这无法折叠我的工具栏,我尝试将其替换为 RecyclerView 仍然无法折叠布局无法折叠。我尝试垂直放置许多 20 个按钮,这能够折叠工具栏我已经在github上尝试了几个例子,在stackoverflow上尝试了几个解决方案,但都被证明是徒劳的如果我能够得到解决方案,将不胜感激

所有的帮助将不胜感激...谢谢

你不需要NestedScrollView

只需删除它,一切就会正常。

UPD_0:

同时尝试将ViewPagers高度设置为 match_parent

android:layout_height="match_parent"

UPD_1:

还尝试将app:layout_scrollFlags="scroll|enterAlways"添加到TabLayoutImageView中,这些CollapsingToolbarLayout

还要确保使用最新版本的designsuport-v7recycler-view库。

这是一个可行的解决方案

activity_main.xml

    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
    <android.support.design.widget.CollapsingToolbarLayout
        android:id="@+id/collapsing_toolbar"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_scrollFlags="scroll|exitUntilCollapsed">
             <ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="centerCrop"
app:layout_collapseMode="parallax"
app:layout_collapseParallaxMultiplier="0.9"
app:layout_scrollFlags="scroll|enterAlways"
android:src="@drawable/babe" />
        <android.support.design.widget.TabLayout
            android:id="@+id/tab_layout"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:layout_gravity="bottom"
            android:background="#ffffff"
            app:tabTextColor="#03A9F4"
            app:tabSelectedTextColor="#0288D1"
            app:tabContentStart="72dp" />

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="@null"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
            app:layout_collapseMode="parallax" />

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

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

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

然后对于片段,按照@mohax的建议删除下一个滚动视图

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.RecyclerView
  xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/recyclerView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity"/>
