Android: CollapsingToolbarLayout and SwipeRefreshLayout get stuck

Question

I use CollapsingToolbarLayout, RecyclerView and SwipeRefreshLayout together:

Code:

    swipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.swipe_container);
    swipeRefreshLayout.setOnRefreshListener(this);

How to allow swipe refresh action only when collapsing toolbar layout is fully expanded and scrollview (recyclerview) on top? The similar behavior like in Google+ or Inbox application.

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);
    }
}
