[Android] PullToRefreshViewAndroid child ListView not scrollable

[Ehesp]

I have a basic example of a ListView, which has a parent PullToRefreshViewAndroid:

        return (
            <PullToRefreshViewAndroid
                refreshing={isRefreshing}
                onRefresh={this.onRefresh}
            >
                <ListView
                    dataSource={races}
                    renderRow={(row) => <Text>{row}</Text>}
                />
            </PullToRefreshViewAndroid>
        );

The outcome of this is that pull to refresh works, but the ListView is not scrollable. The only way to fix this is by applying style={{flex:1}} to PullToRefreshViewAndroid... Is this a bug or intentional? I'd expect PullToRefreshViewAndroid to take the full height of it's child by default?

If it's a bug, I can potentially submit a PR for this.

Could you send a PR mentioning in the docs that flex:1 is required?
