Initial spinner selection

[Simon Craigie]

Hello,

I want to display a hint in my spinner when no selection has been made.  

I am trying to do this by creating a custom ArrayList to use as the spinner source as follows:

public class SpinnerList extends ArrayList<String> {

        @Override

        public int size() {

            int listSize = super.size();

            return listSize <= 0 ? 0 : listSize - 1;

        }

}

list = new SpinnerList();

list.add("foo");

list.add("bar");

list.add.....

list.add.....

list.add.....

list.add.....

list.add(""); // <- when selected, this will display the hint from my spinner textview.

This implementation is working fine with robobinding as index 0 to (n-1) are displayed in the spinner list, however I cannot set the index to the last element nor any other element in my list except position 0 without throwing an error.  

can anybody help with a solution to change the initial item selection?

Thanks!

Hi Simon,

I don't fully understand your problem. Could you send a minimal sample project to weich...@gmail.com or through some other way like github. I will have a look tomorrow and give you a feedback.

Cheers,

Hi Simon,

I re-read your issue. Are you using PresentationModels with aspectj? if so, the bug you mentioned might be to do with the bug #172, which was introduced in the version 0.8.6 and fixed in the version 0.8.7, which has just released.

Hi Simon,

Thanks for the sample project. I tried and found this thread. I think this is a bug that Google has introduced, but i will have a look to see if RoboBinding can have a workaround this. Thanks for a good spot.

Best Regards,

Ok, with further reading. I think it is a bug in RoboBinding.

Hi Simon,

I have fixed the problem. You can have a try with the latest robobinding 0.8.8-SNAPSHOT. For the ItemPresentationModel, i removed AbstractItemPresentationModel in 0.8.7 to prevent confusion. Please have a look the following code sample:

public class ListItemPresentationModel extends AbstractPresentationModel implements ItemPresentationModel<String> {

    private String item;

    public ListItemPresentationModel(){}

    public String getValue(){

        return item;

    }

    @Override

    public void updateData(int index, String item) {

    this.item = item;

    }

}

Best regards,

Cheng Wei
