如何将RecyclerView放在CollapsingToolbarLayout下面,并在Android中折叠时对工具栏做出响应? [英] How to put RecyclerView below CollapsingToolbarLayout and responsive to toolbar when collapsed in Android?
问题描述
我正在开发一个Android应用程序.在我使用的应用程序中,CollapsingtoolbarLayout与RecyclerView一起使用.两者都在工作.但是我在放置它们时遇到了问题.我想要的是我希望RecyclerView位于折叠式Toobar的正下方,并且我希望RecyclerView在折叠时与工具栏一起向上移动.但是我的代码无法正常工作.
I am developing an Android App. In my app I am using, CollapsingtoolbarLayout together with RecyclerView. Both are working. But I am having a problem with positioning them. What I want is I want RecyclerView directly below Collapsing Toobar and I want RecyclerView go up together with toolbar when it is collapsed. But my code is not working as I expected.
这就是现在发生的事情.
This is what happening now.
如您所见,回收站视图的固定位置被工具栏覆盖.它对折叠的工具栏没有响应.
As you can see recycler view is having fixed position covered with toolbar. It is not responsive to collapsed toolbar.
这是我的XML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"
tools:context=".MainActivity">
<android.support.v7.widget.RecyclerView
android:id="@+id/dc_rv_destination"
android:scrollbars="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
<android.support.design.widget.AppBarLayout

android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.design.widget.CollapsingToolbarLayout
android:id="@+id/htab_collapse_toolbar"
android:layout_width="match_parent"
android:layout_height="@dimen/main_activity_parallax_initial_height"
android:fitsSystemWindows="true"

<RelativeLayout
android:layout_width="match_parent"

android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/apple"
android:fitsSystemWindows="true"

app:layout_collapseMode="parallax" />
<TextView
android:layout_centerInParent="true"
android:text="HELLO"
android:textSize="20dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</RelativeLayout>
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="@dimen/main_activity_toolbar_height"
android:gravity="top"
android:minHeight="?attr/actionBarSize"
app:layout_collapseMode="pin"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
app:titleMarginTop="13dp" />
<!-- <android.support.design.widget.TabLayout
android:id="@+id/htab_tabs"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:layout_gravity="bottom"
app:tabIndicatorColor="@android:color/white" />-->
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
</android.support.design.widget.CoordinatorLayout>
在活动中,除了初始化RecyclerView并为其设置数据外,我没有进行任何配置.
In activity, I did not configured anything excepting initializing RecyclerView and setting data to it.
这是我在活动中设置RecyclerView的方式
This is how I set RecyclerView in activity
private void setDestinationRecyclerView()
{
RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(getBaseContext());
rcDestinations.setLayoutManager(mLayoutManager);
rcDestinations.setItemAnimator(new DefaultItemAnimator());
regionsList = new ArrayList<Region>();
destinationsAdapter = new DestinationsAdapter(regionsList,getBaseContext());
rcDestinations.setAdapter(destinationsAdapter);
//add items and notify data changed
}
那么,当折叠时,如何使RecyclerView响应CollapsingToolbarLayout?
So, how can I make RecyclerView responsive to CollapsingToolbarLayout when it is collapsed?
推荐答案
我不知道您是否已修复它.但是你不见了
I don't know if you have already fixed it. However you are missing
app:layout_behavior="@string/appbar_scrolling_view_behavior"
在您的RecyclerView中.
in your RecyclerView.
尝试这样:
<android.support.v7.widget.RecyclerView
android:id="@+id/dc_rv_destination"
android:scrollbars="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_behavior="@string/appbar_scrolling_view_behavior"/>
