Demo ScreenShot & Video(Youtube)

• ListView & GridView

• RecyclerView(With all kinds of layoutManagers)

• WebView & ScrollView & Other Views

• Google SwipeRefreshLayout style

• JD.com Style

• Yalantis Phoenix Style

You can also create your own header and footer. It's very simple.

How to

• Step 1. Add the JitPack repository in your build.gradle at the end of repositories:

repositories {
    maven { url "https://jitpack.io" }
}

• Step 2. Add the dependency in the form

dependencies {
	compile 'com.github.Aspsine:SwipeToLoadLayout:1.0.4'
}

• Step 3. Look over Quick Setup for more details. You can find more customized header view and footer view in the demo app.

swipetoloadlayout's Issues

您好 rcyclerView的问题

按照您的quick setup分别写了listView作为swipe_target和RecyclerView作为swipe_target的两个demo。listView正常可以拉出头部和底部。recyclerView无法拉出头部和底部。代码如下
<com.aspsine.swipetoloadlayout.SwipeToLoadLayout>
<com.gao.baseproject.RefreshHeaderView1
android:layout_width="match_parent"
android:layout_height="100dp"/>
<android.support.v7.widget.RecyclerView
android:id="@id/swipe_target"/>
<com.gao.baseproject.LoadMoreView
android:layout_width="match_parent"
android:layout_height="100dp"/>
</com.aspsine.swipetoloadlayout.SwipeToLoadLayout>

   swipeToLoadLayout = (SwipeToLoadLayout) findViewById(R.id.swipeToLoadLayout);
    recyclerView = (RecyclerView) findViewById(R.id.swipe_target);
    RecyclerView.LayoutManager layoutManager = null;
    layoutManager = new LinearLayoutManager(this);
    recyclerView.setLayoutManager(layoutManager);
    recyclerView.setAdapter(mMyAdpter);
    swipeToLoadLayout.setOnRefreshListener(this);
    swipeToLoadLayout.setOnLoadMoreListener(this);

    swipeToLoadLayout.post(new Runnable() {
        @Override
        public void run() {
            swipeToLoadLayout.setRefreshing(true);
        }
    });

请问如何在adapter加载不同item布局，如何传递数据

上拉加载更多

首先肯定你的下拉刷新真心很不错,但是在改动下拉刷新的时候,我在滚动事件中判断滚动到最后一个item时,自动加载更多,可是加上之后footer 中的一切iew都不显示,要是方便你Q我,那天让你改动过下拉动画那个就是我.谢谢,祝好!

在您这个控件下，ListView 如何设置emptyView

SwipeToLoadLayout限制只能小于三个子控件 请问如何设置emptyView ，或者您的解决方案是什么

ExpandableListView与ListView中，使用有问题

有一个使用ExpandableListView的界面，下拉刷新正常，但是滚到底部再往上滚动的时候会拉出header进行刷新，无法滚到界面头部。
同时，还发现在复杂ListView中，也有这个问题。
布局如下：

下拉刷新松开之前向上拽，阻力变小，icon比手更快向上移动了

ListView中设置EmptyView不起作用

如何能够使ListView作为swipeTagset的时候，能够支持EmptyView的显示

我使用SwipeToLoadLayout和RecyclerView来下拉刷新，刷新之后刷新的界面回不去了

我看了之前的有一个跟我类似的问题，但是我是因为在adapter中设置了Item的点击回调，然后下拉之后就回不去了，请问怎么解决

dispatchTouchEvent

// swipeToRefresh -> finger up -> finger down if the status is still swipeToRefresh
// in onInterceptTouchEvent ACTION_DOWN event will stop the scroller
// if the event pass to the child view while ACTION_MOVE(condition is false)
// in onInterceptTouchEvent ACTION_MOVE the ACTION_UP or ACTION_CANCEL will not be
// passed to onInterceptTouchEvent and onTouchEvent. Instead It will be passed to
// child view's onTouchEvent. So we must deal this situation in dispatchTouchEvent

这个是啥意思？能用中文描述下吗？

使用xutils3的injectView注入获取控件，on a null object reference

获取SwipeToLoadLayout的内部及自身控件，比如com.aspsine.swipetoloadlayout.SwipeToLoadLayout，RecyclerView等都会null

拷贝项目

你好
是这样的，我把你项目里的libary 拷贝到我的项目类库中，但是却在layout 文件 引用不到？
感谢！

怎么关闭Log输出？

焦点问题

layout issue

用这个之后页面不能添加其他布局？ 如页面上面固定了一个Linearlayout 下面在添加这个SwipeTOLoadLayout 这种布局的情况下 上面的固定区域会被覆盖看不到了 当然底部固定一个区域也是会被覆盖的

因为issue类别不一样，删除了你在另外一个issue中的留言。专门开一个issue讨论这个问题。

我测试过，没出现你说的问题。可以麻烦您能把布局文件贴出来么？
@hxingever

The content of the adapter has changed but ListView did not receive a notification

使用ViewPager+Fragment，SwipeToLoadLayout还没刷新完成，就快速切换到其它页面，很容易出现以下错误：
java.lang.IllegalStateException: The content of the adapter has changed but ListView did not receive a notification. Make sure the content of your adapter is not modified from a background thread, but only from the UI thread. Make sure your adapter calls notifyDataSetChanged() when its content changes. [in ListView(2131558425, class android.widget.ListView) with Adapter(class android.widget.HeaderViewListAdapter)]

之前有说这样解决：
崩溃问题是更新了数据源之后没有调用notifyDataSetChanged()。比如如下使用方式就可能出现崩溃。

onSuccess(data){
mList.addAll(data);
swipeToLoadLayout.setRefreshing(false);
mAdapter.notifyDataSetChanged();
}
按照上面这样的用法，就会出现如上崩溃。
请修改为：

onSuccess(data){
swipeToLoadLayout.setRefreshing(false);
mList.addAll(data);
mAdapter.notifyDataSetChanged();
}

我是那么做的，但是还是不行。

当列表滑动到顶部或者底部时，列表项的点击不灵敏

当列表滑动到顶部或者底部时，快速点击列表项会发现点击不灵敏，有些点击事件会触发上拉或者下拉，希望优化下，这个库就完美了

ExpandableListView

ExpandableListView can use this to refresh and load more ? thans.

你好 1.0.3 通过gradle 依赖 弄不下来

OnRefresh,OnLoadMore方法多次被调用

你好。在Demo里面，onrefresh(),onloadmore()方法会被多次调用的，产生多个网络请求。请问这是不是一个bug？

always stop at refreshing

一直停留在这个界面,无法自动回缩
大可乐3,Android 4.4.4

fragment嵌套fragment的时候,无法显示控件

你好作者,我在fragment中嵌套了一个fragment,在最里层的fragment中加入了刷新控件,但是始终无法显示,请指教!

It would be great to be able to customise DEFAULT_DRAG_RATIO

It would be very cool for us to have a setDragRatio() method in order to customize the DEFAULT_DRAG_RATIO value.

It would be also great to have a way to customize (DEFAULT_DRAG_RATIO * 4) with another value.

Thanks.

和RecyclerView一起使用碰到的问题

我自定义了刷新和加载的样式，但是不会显示出来，刷新和加载能成功，就是没有显示我自己的样式，我自定义的样式是继承TextView，我的RecyclerView的item中没有TextView，请问是这个原因吗？

the swipe_target view not show complete

when the swipe_target view is a RelativeLayout who contains the two child view(recyclerview and LinearLayout) , then the recyclerview contains many item, the swipe_target only show one screen
the xml code
`
<com.duoniu.benfu.widget.layout.SwipeToLoadLayoutEmptySupport

android:layout_height="wrap_content"
app:swipe_style="classic">

<include
    android:id="@+id/swipe_refresh_header"
    layout="@layout/layout_logo_header"/>


<RelativeLayout

</RelativeLayout>



<include
    android:id="@+id/swipe_load_more_footer"
    layout="@layout/layout_classic_footer"/>

</com.duoniu.benfu.widget.layout.SwipeToLoadLayoutEmptySupport>`

how can i solve it?

SwipeToLoadLayout 布局只能是layout根布局吗？

可不可以

<com.aspsine.swipetoloadlayout.SwipeToLoadLayout />

recyclerView无法拉出头部和底部

按照您的quick setup分别写了listView作为swipe_target和RecyclerView作为swipe_target的两个demo。listView正常可以拉出头部和底部。recyclerView无法拉出头部和底部。都是独立activity。
代码如下

<com.aspsine.swipetoloadlayout.SwipeToLoadLayout>

    <com.gao.baseproject.RefreshHeaderView1
        android:layout_height="100dp"
        android:layout_width="match_parent" />

    <android.support.v7.widget.RecyclerView
        android:id="@id/swipe_target" />

    <com.gao.baseproject.LoadMoreView
        android:layout_height="100dp"
        android:layout_width="match_parent" />
</com.aspsine.swipetoloadlayout.SwipeToLoadLayout>

swipeToLoadLayout = (SwipeToLoadLayout) findViewById(R.id.swipeToLoadLayout);
recyclerView = (RecyclerView) findViewById(R.id.swipe_target);
RecyclerView.LayoutManager layoutManager = null;
layoutManager = new LinearLayoutManager(this);
recyclerView.setLayoutManager(layoutManager);
recyclerView.setAdapter(mMyAdpter);
swipeToLoadLayout.setOnRefreshListener(this);
swipeToLoadLayout.setOnLoadMoreListener(this);

swipeToLoadLayout.post(new Runnable() {
    @Override
    public void run() {
        swipeToLoadLayout.setRefreshing(true);
    }
});

CoordinatorLayout 与SwipToLoadLayout 结合使用问题

上拉加载无法正常运行 ，

好像不能嵌套CoordinatorLayout

<com.aspsine.swipetoloadlayout.SwipeToLoadLayout xmlns:android="http://schemas.android.com/apk/res/android"

                <TextView
                    android:layout_width="wrap_content"

                    android:text="the best app" />
            </LinearLayout>

            <android.support.design.widget.TabLayout

                android:layout_height="40dp"
                android:background="#810e88" />

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

        <android.support.v4.view.ViewPager
            android:id="@+id/vp_body"

下拉刷新头部进度条会不显示

这个库感觉挺不错的，但是有些细节可以改进下：
1.如果最外层嵌套的是LinearLayout，下拉刷新头部进度条会不显示。换成RelativeLayout就正常了；
2.ListView的头部与底部的分割线在有HeaderView和FootView的时候是不显示的；
3.加载完成更多，会弹回去，而不是直接显示数据，体验可以改进；
4.主动刷新会先显示下拉即可刷新，然后再显示正在刷新，如果改成直接正在刷新，体验会更好。

setSwipeStyle()

可不可以分别设置头部与底部的STYLE；

比如头部的样式为STYLE.ABOV，而底部的样式为STYLE.SCALE

或者，同时存在整体STYLE、头部STYLE、底部STYLE。

试着改了一下源码，没有成功，因为设置中间部分的STYLE，这部分不知道该怎么设置它的STYLE。

How to achieve Auto-LoadMore?

希望能支持 上拉到顶部 自动加载更多

刷新状态的改变

SwipeToLoadLayout的刷新过程中是停留在顶部的, 可不可以加一种状态就是在刷新的时候 可以像其他刷新一样在刷新的过程中上划隐藏头部. 还望作者可以帮忙解决, 本来想自己改的但是没有搞定. 希望作者可以联系我 或者直接在这里回复我. [email protected].谢谢

加载更多完成后

目前当加载更多完成后，footer消失，列表回弹footer的高度，到底部，加载的内容不能立即显示，能否实现列表不动，footer消失，加载的内容显示在footer的位置？

关于loadmore的一点细节问题

当上拉加载完成后，能不能让RecyclerView向上滚动一点距离，让loadmore进来的数据露出一部分，这样能很直观看到数据已经加载进来了，而不是现在必须再手动滚动一次才能看到新数据

当布局里scrollview嵌套listview会引起空指针

上拉加载更多，加载完成后能否让加载的数据直接在FooterView的位置显示，不让recycleview向下回弹到底部

“下拉加载完毕时，目前是隐藏进度加载指示器，然后 recycleview 回弹到底部，这样别人就看不到加载成功的内容，能否把显示进度指示器这块内容用来显示加载更多的内容呢，这样效果是否更好呢？”

下拉刷新获得更多数据后，可否让listview自动上移一点，以便显示有更多数据加载了

android:allowBackup="true"

android:allowBackup="true"
会引发安全漏洞

refreshHeader layout issue

很棒的代码。:D
但是我在使用的时候发现 定制下拉刷新的头部布局文件中，控件貌似必须要给出精确的宽度或者默认值，否则就显示不出来…譬如TextView 要么指定宽度，要么设置android:text=”xxx“ 否则下拉的时候就是空白的，但是功能都是正常的。

刷新效果不对

使用的这个类SwipToLoadLayoutGoogleCustomHeader
下拉刷新的时候 ，那个圆圈我建议是怎么出来就怎么回去，刷新完成了之后 会 慢慢缩回去，有时候会直接消失，刷新完成之后直接消失 这个问题请问怎么解决。

我有一个很长的详情页，所以用了ScrollView，然后在底部有个评论列表，我用了你的这个layout，然后发现是空白的，我去掉了ScrollView，保留少量内容，可以看到你的layout可以正常工作，加上ScrollView，你的layout又空白了，我固定了你的layout的高度，看到里面有内容的，所以估计是高度被错误算成了0。

请问像我这样情况有没有办法？

你好，我有个疑问

你好，我有个疑问，我在自定义刷新头部的时候，实现 SwipeRefreshTrigger, SwipeTrigger这两个接口后，复写的那些方法是什么意思，比如onComplete()，是指刷新的时候请求数据完成的时候调用还是指什么？谢谢！

锤子手机下拉刷新失败

锤子手机多次下拉后下拉失效，没有反应。

下拉刷新不弹回

最近遇到一个问题，初次进入首页，先自动刷新，在刷新过程中，瞬间切换到其他Fragment页面，然后返回到开始的页面，发现下拉刷新不弹回，每次都能测试出来。

后面突然还出现一次奔溃：

请教个 CoordinatorLayout 和 AppBarLayout 提早下拉刷新的问题

先看布局

<android.support.v4.widget.DrawerLayout
    android:id="@+id/drawer_layout"
    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:openDrawer="start">

    <android.support.design.widget.CoordinatorLayout
        android:id="@+id/main_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fitsSystemWindows="true"
        tools:context=".android.core.activities.MainActivity">

        <include layout="@layout/include_app_bar_layout"/>

        <FrameLayout
            android:id="@+id/content_frame"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            app:layout_behavior="@string/appbar_scrolling_view_behavior">

        </FrameLayout>

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

</android.support.v4.widget.DrawerLayout>

上面 <include layout="@layout/include_app_bar_layout"/> 就是下面的 AppBarLayout。
中间的 FrameLayout 是主内容，是给Fragment的，Fragment的布局就是你的SwipeToLoadLayout

AppBarLayout

<android.support.design.widget.AppBarLayout
    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="wrap_content"
    android:animateLayoutChanges="true"
    android:theme="@style/AppTheme.AppBarOverlay">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="@dimen/toolbar_height"
        android:layout_gravity="center"
        android:layout_marginEnd="@dimen/toolbar_margin"
        android:layout_marginLeft="@dimen/toolbar_margin"
        android:layout_marginRight="@dimen/toolbar_margin"
        android:layout_marginStart="@dimen/toolbar_margin"
        android:paddingTop="@dimen/toolbar_padding_top_basic"
        app:layout_scrollFlags="scroll|enterAlways"
        app:popupTheme="@style/AppTheme.PopupOverlay">

        <include layout="@layout/include_toolbar_basic_light"/>
        <include layout="@layout/include_toolbar_basic_dark"/>

    </android.support.v7.widget.Toolbar>

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

SwipeToLoadLayout

<com.aspsine.swipetoloadlayout.SwipeToLoadLayout
    android:id="@+id/refresh_layout"
    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">

    <!--
    Don't add anything nor change the view id, SwipeToLoadLayout hard coded
    the view id, and only accept max 3 child views.
    -->

    <cn.com.cityweekend.android.utils.views.RefreshHeaderView
        android:id="@+id/swipe_refresh_header"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        app:indicator_color="@color/colorPrimary"/>

    <android.support.v7.widget.RecyclerView
        android:id="@+id/swipe_target"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scrollbars="vertical"/>

    <cn.com.cityweekend.android.utils.views.LoadMoreFooterView
        android:id="@+id/swipe_load_more_footer"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        app:indicator_color="@color/colorPrimary"/>

</com.aspsine.swipetoloadlayout.SwipeToLoadLayout>

再看截图
这是初始状态

上面蓝色区域整个都是 AppBarLayout，里面就是自己加了几个image和button。
蓝色区域下面就是你的SwipeToLoadLayout。

初始状态下下拉当然是没有问题的，如下图

当屏幕往上滚动的时候，AppBarLayout 整个会一起滚上去，然后往下滚动的时候，AppBarLayout 会马上出现，等 AppBarLayout 全部出现后，然后列表（RecyclerView）才开始滚动，这是 CoordinatorLayout 和 AppBarLayout 组合的效果。
问题就在于，如果滚动状态停在 AppBarLayout 出现一半的时间，松手，然后在往下滚动的时候，会出现下拉刷新，如下图

这样 AppBarLayout 就显示不全了，必须要先往上滚动一下，不松手，再往下滚动，就是正常的效果。

这就是我所谓的“提早下拉刷新的问题”，我稍后录个频帮助理解。
