Android - Swipe to Refresh
Start
  How to add Swipe-to-Refresh To your app

Make sure the following dependency is added to your app's build.gradle file under dependencies:

compile 'com.android.support:support-core-ui:24.2.0'

Then add the SwipeRefreshLayout in your layout:

<android.support.v4.widget.SwipeRefreshLayout
        android:id="@+id/swipe_refresh_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

     <!-- place your view here -->       

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

Finally implement the SwipeRefreshLayout.OnRefreshListener listener.

mSwipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.swipe_refresh_layout);
mSwipeRefreshLayout.setOnRefreshListener(new OnRefreshListener() {
    @Override
    public void onRefresh() {
         // your code
    }
});
  Swipe To Refresh with RecyclerView

To add a Swipe To Refresh layout with a RecyclerView add the following to your Activity/Fragment layout file:

<android.support.v4.widget.SwipeRefreshLayout
    android:id="@+id/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="wrap_content"
        android:orientation="vertical"
        android:scrollbars="vertical" />

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

In your Activity/Fragment add the following to initialize the SwipeToRefreshLayout:


   SwipeRefreshLayout mSwipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.refresh_layout);
    mSwipeRefreshLayout.setColorSchemeResources(R.color.green_bg,
            android.R.color.holo_green_light,
            android.R.color.holo_orange_light,
            android.R.color.holo_red_light);

    mSwipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
        @Override
        public void onRefresh() {
            // Execute code when refresh layout swiped
        }
    });

Syntax

  1. setColorSchemeResources sets the colors of the SwipeToRefreshLayout indicator
  2. setOnRefreshListener sets what to do when layout is swiped
  3. app:layout_behavior="@string/appbar_scrolling_view_behavior" if you have a Toolbar with your layout, add this with the scrollFlags in Toolbar and the Toolbar will slide up while scrolling down and slide in again while scrolling up.
