我是Android开发的新手。我正在使用回收站视图来显示列表。我假设它具有滚动的默认行为,但它没有发生。任何人都可以给我一些建议。以下是我正在使用的布局。
<?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:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:background="@android:color/transparent"
tools:context="com.team.sidhesh.MainActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/background"
android:theme="@style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:popupTheme="@style/AppTheme.PopupOverlay" />
<ImageView
android:id="@+id/sliderTempImageView"
android:layout_width="match_parent"
android:layout_height="@dimen/slider_image_height"
android:src="@drawable/homescreen_logo"
android:scaleType="fitCenter"
android:background="@android:color/transparent"/>
<android.support.v7.widget.RecyclerView
android:id="@+id/recycler_view"
android:background="@android:color/transparent"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="vertical"
android:paddingBottom="10dp"/>
</android.support.design.widget.AppBarLayout>
</android.support.design.widget.CoordinatorLayout>

试试这个:
<?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:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:background="@android:color/transparent"
tools:context="com.team.sidhesh.MainActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/background"
android:theme="@style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:popupTheme="@style/AppTheme.PopupOverlay" />
<ImageView
android:id="@+id/sliderTempImageView"
android:layout_width="match_parent"
android:layout_height="@dimen/slider_image_height"
android:src="@drawable/homescreen_logo"
android:scaleType="fitCenter"
android:background="@android:color/transparent"/>
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="470dp"
android:layout_weight="1"
android:background="@android:color/darker_gray"
app:layout_behavior="@string/appbar_scrolling_view_behavior">
<android.support.v7.widget.RecyclerView
android:id="@+id/recycler_view"
android:background="@android:color/transparent"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="vertical"
android:paddingBottom="10dp"/>
</android.support.v4.widget.NestedScrollView>
</android.support.design.widget.AppBarLayout>
</android.support.design.widget.CoordinatorLayout>
还要确保在gradle文件中添加依赖项
compile 'com.android.support:recyclerview-v7:22.2.0'

为什么在RecyclerView
中使用AppBarLayout
?它不应该在CoordinatorLayout
以外AppBarLayout
之下吗?
要达到您的期望,请点击此链接:https://developer.android.com/reference/android/support/design/widget/AppBarLayout.html
显示/说:<!-- Your scrolling content -->
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior">
<!-- Your scrolling content -->
</android.support.v4.widget.NestedScrollView>
因此,您需要将RecyclerView
放在AppBarLayout
之外,然后添加:app:layout_behavior =&#34; @ string / appbar_scrolling_view_behavior&#34;到RecyclerView
。我已将AppBarLayout
layout_height
设置为wrap_content
。
<?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:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@android:color/transparent"
android:fitsSystemWindows="true"
tools:context="com.team.sidhesh.MainActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@drawable/background"
android:theme="@style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:popupTheme="@style/AppTheme.PopupOverlay" />
<ImageView
android:id="@+id/sliderTempImageView"
android:layout_width="match_parent"
android:layout_height="@dimen/slider_image_height"
android:background="@android:color/transparent"
android:scaleType="fitCenter"
android:src="@drawable/homescreen_logo" />
</android.support.design.widget.AppBarLayout>
<android.support.v7.widget.RecyclerView
android:id="@+id/recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@android:color/transparent"
android:paddingBottom="10dp"
android:scrollbars="vertical"
app:layout_behavior="@string/appbar_scrolling_view_behavior" />
</android.support.design.widget.CoordinatorLayout>
那ImageView
到底是什么?使用Slider?那么也许你需要将它与CollapsingToolbarLayout
一起放在一起!

您应该做的是将recyclerView包装到Scrollview或HorizontalscrollView
