Can I filter null object before asRxObservable() ?

[xanderwang]

I use storIO.get().listOfObjects().withGetResolver().asRxObservable() to observable database change. But the result is not I want, because my GetResolver will return null object , when i show the chane result , i skip the null object . Can I filter null object before asRxObservable() ?

the version is compile 'com.pushtorefresh.storio:sqlite:1.8.0' compile 'com.pushtorefresh.storio:content-resolver:1.9.0'

What is recorder?

sorry,I did not describe clearly.There is no record in my database, it is empty

StorIO should notify you with empty result then. storIO.get()…asRxObservable() emits initial result.

In case of empty db:

• storIO.get().listOfObjects() will emit empty List
• storIO.get().cursor() will emit empty Cursor
• storIO.get().object() will emit null

i find my error, i use storIO.get().listOfObjects() and my GetResolver will return null object, when i show GetResolver return data , i skip the null object , so i see no data in my app. Can i filter null object before asRxObservable()
