Android Lollipop - Pull to refresh

Question

I am trying to implement pull-to-refresh in Android. I know there is SwipeRefreshLayout but with all the newly designed Google apps like Drive (see attached) for Lollipop, I have noticed there is a new refresh icon that comes in the view when pulled. I tried looking it online but in vain. Has Android released this as a part of the Material Design? Any ideas about how to implement it?

EDIT: Some people have pointed out how this is a duplicate of How to implement a Pull-to-refresh. It is not the same question. You'll see it if you read the question properly.

Answer 1

This is SwipeRefreshLayout . Version 21 of the support library includes it replacing the old style.

Answer 2

1. Download the latest Lollipop SDK and Extras/Android support library
2. Set Project's Build Target to Android 5.0 (otherwise support package can have errors with resources)
3. Update your libs/android-support-v4.jar to 21st version
4. Use android.support.v4.widget.SwipeRefreshLayout plus android.support.v4.widget.SwipeRefreshLayout.OnRefreshListener

Detailed guide could be found here: http://antonioleiva.com/swiperefreshlayout/

Plus for ListView I recommend to read about canChildScrollUp() in the comments ;)

Answer 3

I like this guide the best and its really easy to understand: https://www.bignerdranch.com/blog/implementing-swipe-to-refresh/

1. Add the following to gradle:

   compile 'com.android.support:support-v4:22.2.0'

2. Add the swipe to refresh to your layout - put in listview or recyclerview in the middle of the swiperefreshlayout:

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

3. Add in your code for the mainactivity:

   public class MainActivity extends Activity {
   
   ListView mListView;
   SwipeRefreshLayout mSwipeRefreshLayout;
   Adapter mAdapter;
   
   @Override
   public void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
     setContentView(R.layout.acivity_main);
     SwipeRefreshLayout mSwipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.activity_main_swipe_refresh_layout);
     mListView = findViewById(R.id.activity_main_list_view);
     mListView.setAdapter(new ArrayAdapter<String>(){
     String[] fakeTweets = getResources().getStringArray(R.array.fake_tweets);
     mAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, fakeTweets)
     listView.setAdapter(mAdapter);
   });
   }
   

   }

4. Don't forget to call mSwipeRefreshLayout.setRefreshing(false); once your refreshing ends.
