Android:CollapsingToolbarLayout 和 SwipeRefreshLayout 卡住了

如何在折叠工具栏布局完全展开和滚动视图(recyclerview)开启时仅允许滑动刷新操作顶? Google+ 或收件箱应用程序中的类似行为。

更新:此问题已在最新版本的支持库(23.1.1+)中得到解决。如果您使用的是旧版本的支持库,请升级或继续阅读。
如果您使用的是旧版本的支持库,请将偏移量更改侦听器添加到您的 AppBarLayout 以启用或禁用您的滑动以相应地刷新布局。此处提供其他代码:
https://gist.github.com/blackcj/001a90c7775765ad5212
相关变更:
public class MainActivity extends AppCompatActivity implements AppBarLayout.OnOffsetChangedListener {
...
private AppBarLayout appBarLayout;
private SwipeRefreshLayout mSwipeRefreshLayout;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
...
mSwipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.contentView);
appBarLayout = (AppBarLayout) findViewById(R.id.appBarLayout);
}
@Override
public void onOffsetChanged(AppBarLayout appBarLayout, int i) {
//The Refresh must be only active when the offset is zero :
mSwipeRefreshLayout.setEnabled(i == 0);
}
@Override
protected void onResume() {
super.onResume();
appBarLayout.addOnOffsetChangedListener(this);
}
@Override
protected void onPause() {
super.onPause();
appBarLayout.removeOnOffsetChangedListener(this);
}
}
如果我没理解错的话,你是想在工具栏展开后才开始刷新,对吧?所以首先需要打开CollapsingToolbarLayout,然后开始刷新。我通过以下代码管理它:
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/coordinator_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<android.support.design.widget.AppBarLayout
android:id="@+id/app_bar_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fitsSystemWindows="true"
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="wrap_content"
android:fitsSystemWindows="true"
app:layout_scrollFlags="scroll|enterAlways|enterAlwaysCollapsed">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<!--PUT HERE WHAT EVER YOU WANT TO COLLAPSE, A TOOLBAR, ETC...-->
</LinearLayout>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v4.widget.SwipeRefreshLayout
android:id="@+id/swipe_refresh_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior">
<android.support.v7.widget.RecyclerView
android:id="@+id/recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clipToPadding="false"
android:fadeScrollbars="false"
android:scrollbars="vertical"
app:layout_behavior="@string/appbar_scrolling_view_behavior" />
</android.support.v4.widget.SwipeRefreshLayout>
</android.support.design.widget.CoordinatorLayout>
然后,在你的fragment/activity中实现AppBarLayout.OnOffsetChangedListener(现在工具栏完全展开时启用刷新):
@Override
public void onOffsetChanged(AppBarLayout appBarLayout, int verticalOffset) {
if (collapsingToolbarLayout.getHeight() + verticalOffset < 2 * ViewCompat.getMinimumHeight(collapsingToolbarLayout)) {
swipeRefreshLayout.setEnabled(false);
} else {
swipeRefreshLayout.setEnabled(true);
}
}
重写 onPause() 和 onResume(),如@blackcj 的回答:
@Override
public void onResume() {
super.onResume();
appBarLayout.addOnOffsetChangedListener(this);
}
@Override
public void onPause() {
super.onPause();
appBarLayout.removeOnOffsetChangedListener(this);
}
然后将 LinearLayoutManager 设置为您的 recyclerView:
LinearLayoutManager layoutManager = new LinearLayoutManager(getActivity());
layoutManager.setOrientation(LinearLayoutManager.VERTICAL);
recyclerView.setLayoutManager(layoutManager);
对我来说这很有用,首先 appBarlayout 得到扩展,然后 swipeRefreshLayout 触发刷新。
最后,
我发现 SwipeRefreshLayout 工作 没有来自支持库版本 23.1.1.
的任何 "hacks"
只需在您的布局中使用:
<android.support.v4.widget.SwipeRefreshLayout
android:id="@+id/swipe_refresh_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior">
<android.support.v7.widget.RecyclerView
android:id="@+id/recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="vertical" />
</android.support.v4.widget.SwipeRefreshLayout>
在代码中:
SwipeRefreshLayout swipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.swipe_refresh_layout);
swipeRefreshLayout.setColorSchemeResources(R.color.green, R.color.red, R.color.yellow);
swipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
@Override
public void onRefresh() {
//Your refresh code here
}
});
别忘了使用:
swipeRefreshLayout.setRefreshing(false);
使用您的代码逻辑后 ;)
非常适合 AppCompatActivity
但如果您使用 Fragment
那么下面的代码片段将对您有所帮助。
只需将 NestedScrollView
放在 fragment
的 xml 中
<android.support.v4.widget.NestedScrollView 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:layout_gravity="fill_vertical"
android:clipToPadding="false"
android:isScrollContainer="false"
app:layout_behavior="@string/appbar_scrolling_view_behavior">
<!-- A RecyclerView with some commonly used attributes -->
<android.support.v4.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/album_timeline_swipe_refresh_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:id="@+id/album_timeline_recyclerview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clickable="true" />
</android.support.v4.widget.SwipeRefreshLayout>
</android.support.v4.widget.NestedScrollView>
我必须让 RecyclerView 成为 SwipeRefreshLayout 的主要子元素,以便使用支持库 23.2.0 解决问题。无法修复它在 SwipeRefreshLayout
中具有 include 布局
<android.support.v4.widget.SwipeRefreshLayout
android:id="@+id/my_swipeRefreshLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!--<include layout="@layout/my_RecyclerView_layout"/> issue for me here -->
<android.support.v7.widget.RecyclerView
android:id="@+id/my_recyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent">
</android.support.v7.widget.RecyclerView>
</android.support.v4.widget.SwipeRefreshLayout>
它对我来说与 offsetChangedListener 一起工作,只是性能更好一点的 kotlin onOffsetChanged() 实现
val toEnable = verticalOffset == 0
if (!swipeRefresh.isEnabled.xor(toEnable)) return
swipeRefresh.isEnabled = toEnable
