When switch fragment with SwipeRefreshLayout during refreshing, fragment freezes but actually still work

Question

UPDATE: I thought it worked correctly. But after some test trouble still exists *sniff*

Then I made a simpler version to see what exactly happen and

For the time being, you can avoid the issue by:

public class FixedRefreshLayout extends SwipeRefreshLayout {

    private static final String TAG = "RefreshTag";
    private boolean selfCancelled = false;

    public FixedRefreshLayout(Context context) {
        super(context);
    }

    public FixedRefreshLayout(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    protected Parcelable onSaveInstanceState()
    {
        if(isRefreshing()) {
            clearAnimation();
            setRefreshing(false);
            selfCancelled = true;
            Log.d(TAG, "For hide refreshing");
        }
        return super.onSaveInstanceState();
    }

    @Override
    public void setRefreshing(boolean refreshing) {
        super.setRefreshing(refreshing);
        selfCancelled = false;
    }

    @Override
    public void onWindowFocusChanged(boolean hasWindowFocus) {
        super.onWindowFocusChanged(hasWindowFocus);
        if(hasWindowFocus && selfCancelled) {
            setRefreshing(true);
            Log.d(TAG, "Force show refreshing");
        }
    }
}

This has the added advantage of resuming the animation incase you decide to not switch the fragment (coming from some menu). It also ties in with the internal animation to make sure that the refreshing animation does not return if the network refresh has already completed.
