AppBarLayout + TabLayout + CollapsingToolbarLayout + SwipeToRefresh [英] AppBarLayout + TabLayout + CollapsingToolbarLayout + SwipeToRefresh
问题描述
我遇到了很多与问题相关的问题,但没有人发现我想要的行为.
I met a lot of issues related with my problem but nobody I found wanted the behaviour I'm looking for.
我想要一个带有选项卡和应用程序栏的视图寻呼机,当所包含的片段可滚动并滚动(向底部)时,我希望应用程序栏消失,但当向顶部滚动时,这些选项卡会重新出现.其中一些片段包含SwipeToRefresh布局(有时会引起问题). 我尝试了很多配置,这些配置总是会出问题.
I want a view pager with tabs and app bar, when the contained fragments are scrollable and are scrolled (toward bottom), I want the app bar to disapear but leave the tabs, when scrolled toward top, to re-apear. some of these fragments contain a SwipeToRefresh Layout (sometimes it causes problems). I tried a lot of configurations that always leave something wrong.
现在我没有崩溃的效果(它总是隐藏的)
for now I don't have the collapsing effect (it's always hidden)

和我的片段之一(滚动的一个):
and one of my fragment (the scrolling one) :
<?xml version="1.0" encoding="utf-8"?>

android:layout_width="match_parent"

android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="vertical" />
</RelativeLayout>
</android.support.v4.widget.SwipeRefreshLayout>
</FrameLayout>
我不知道我到底做了什么,但是从我开始写这个问题开始,refreshLayout阻止了我的List上升(而是刷新).
I don't know exactly what I've done but from the time I started write this question the refreshLayout prevent my List from going up (it refreshes instead)..
谢谢

感谢邹国伟爵士,它现在可以与以下xml一起使用:
thanks to Sir Ellie Zou, it now works with this xml :
<?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"

android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context=".MainPagerActivity">
<android.support.design.widget.AppBarLayout
android:id="@+id/app_bar_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:layout_collapseMode="pin"

android:layout_width="match_parent"
android:layout_height="wrap_content"

</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager

android:layout_width="match_parent"
android:layout_height="match_parent"

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

android:layout_gravity="bottom|end"
android:layout_margin="@dimen/fab_margin"
android:src="@android:drawable/ic_menu_edit" />
</android.support.design.widget.CoordinatorLayout>
和片段布局:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:wheel="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.m360learning.app.fragment.MainPagerNewsFeed">
<com.pnikosis.materialishprogress.ProgressWheel
android:id="@+id/progress_wheel"
android:layout_width="80dp"
android:layout_height="80dp"
android:layout_gravity="center"
wheel:matProg_barColor="#5588FF"
wheel:matProg_progressIndeterminate="true" />
<android.support.v4.widget.SwipeRefreshLayout
android:id="@+id/swipeRefreshLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:id="@+id/recycler"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="vertical" />
</android.support.v4.widget.SwipeRefreshLayout>
</FrameLayout>
推荐答案
如果您不希望有视差效果,则无需使用CollapsingToolbarLayout
.
If you don't want parallax effect, you don't need to use CollapsingToolbarLayout
.
最重要的配置:
在工具栏中,设置app:layout_scrollFlags="scroll|enterAlways"
.
在ViewPager中,设置app:layout_behavior="@string/appbar_scrolling_view_behavior"
.
In ViewPager, set app:layout_behavior="@string/appbar_scrolling_view_behavior"
.
布局应如下所示:
<android.support.design.widget.CoordinatorLayout>
<android.support.design.widget.AppBarLayout>
<android.support.v7.widget.Toolbar/>
<android.support.design.widget.TabLayout/>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager/>
<android.support.design.widget.FloatingActionButton/>
</android.support.design.widget.CoordinatorLayout>
将ProgressWheel
移出SwipeRefreshLayout
,以解决SwipeRefreshLayout无法刷新的问题.
Move ProgressWheel
out of your SwipeRefreshLayout
to fix your problem that SwipeRefreshLayout can't refresh.
