Toolbar not showing with swipe to refresh

Question

I'm trying to implement collapsing tollbar with swipe to refresh and recyclerview. When I'm trying to scroll (when recyclerview has only one item) toolbar collapse, but when I'm trying to scroll down to show toolbar, it's impossible because swipe down causes swipe to refresh. When recyclerview has more item it works perfectly.

Answer 1

Update: This bug has been fixed in the version 23.1.1 of support library

You can set onOffsetChanged listener for your AppBarLayout and prevent to swipe refreshing until AppBarLayout layout offset 0.

This is good example : https://gist.github.com/blackcj/001a90c7775765ad5212

Answer 2

I managed it by adding the following implementation of OnOffsetChangedListener in fragment:

@Override
public void onOffsetChanged(AppBarLayout appBarLayout, int verticalOffset) {
    if (collapsingToolbarLayout.getHeight() + verticalOffset < 2 * ViewCompat.getMinimumHeight(collapsingToolbarLayout)) {
        swipeRefreshLayout.setEnabled(false);
    } else {
        swipeRefreshLayout.setEnabled(true);
    }
}

@Override
public void onResume() {
    super.onResume();
    appBarLayout.addOnOffsetChangedListener(this);
}

@Override
public void onPause() {
    super.onPause();
    appBarLayout.removeOnOffsetChangedListener(this);
}
