I use CollapsingToolbarLayout, RecyclerView and SwipeRefreshLayout together:
Xml:
If I understand you correctly, you want to start refreshing only after toolbar is expanded, right? So first CollapsingToolbarLayout needs to be opened and then start refreshing. I managed it by the following code:
<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>
And then, in your fragment/activity make it implement AppBarLayout.OnOffsetChangedListener (Now the refreshing is enabled when toolbar is fully expanded):
@Override
public void onOffsetChanged(AppBarLayout appBarLayout, int verticalOffset) {
if (collapsingToolbarLayout.getHeight() + verticalOffset < 2 * ViewCompat.getMinimumHeight(collapsingToolbarLayout)) {
swipeRefreshLayout.setEnabled(false);
} else {
swipeRefreshLayout.setEnabled(true);
}
}
Override onPause() & onResume() as in @blackcj answer:
@Override
public void onResume() {
super.onResume();
appBarLayout.addOnOffsetChangedListener(this);
}
@Override
public void onPause() {
super.onPause();
appBarLayout.removeOnOffsetChangedListener(this);
}
Then set LinearLayoutManager to your recyclerView:
LinearLayoutManager layoutManager = new LinearLayoutManager(getActivity());
layoutManager.setOrientation(LinearLayoutManager.VERTICAL);
recyclerView.setLayoutManager(layoutManager);
For me this worked as a charm, first appBarlayout gets expanded and only then swipeRefreshLayout triggers refreshing.
Update: This issue has been resolved in the latest version of the support library (23.1.1+). If you are using an older version of the support library either upgrade or continue reading.
If you're using an older version of the support library, add an offset change listener to your AppBarLayout to enable or disable your swipe to refresh layout accordingly. Additional code available here:
https://gist.github.com/blackcj/001a90c7775765ad5212
Relevant changes:
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);
}
}
I had to make the RecyclerView the main child of the SwipeRefreshLayout in order to remove the issue using Support Library 23.2.0. Could not fixed it having an include layout inside of the SwipeRefreshLayout
<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>
The Above Answer is Perfect for AppCompatActivity
but If you are used Fragment
then following snippet will help you.
Just put NestedScrollView
in xml of fragment
<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>
Finally,
I found that SwipeRefreshLayout works without any "hacks" from Support Library version 23.1.1.
Simply use in your layout:
<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>
and in code:
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
}
});
And don't forget to use:
swipeRefreshLayout.setRefreshing(false);
after using your code logic ;)
