radiogroup + radio buttons

[Johnny TwoShoes]

Hi,

I have a radio group with radio buttons (3). I bind to a class, but, if on creation , if I leave out the radio buttons (since, I don't want a default value, rather the user must select one) , radiobinding doesn't work correctly ( I can't remember the side affects). the xml for the radio button is:

android:text="Yes"

bind:checked="{checked1}"

android:text="No"

bind:checked="{checked2}"

android:text="NA"

bind:checked="{checked3}"

and in the viewmodel:

    private Boolean checked1;

    private Boolean checked2;

    private Boolean checked3;

    private String sel;

Depending on whether  sel = Yes/No/NA, one of the three checkboxes is selected; on initialization. If I leave sel blank, it seems to corrupt the binding???

Any ideas most appreciated.

kind regards

Hi Johnny,

You are right. At the moment, preinitializingViews flag control whether to preinitialize views, but it is on PresentationModel level. So please use android standard way instead in this case.

This will be supported once https://github.com/RoboBinding/RoboBinding/issues/164 and https://github.com/RoboBinding/RoboBinding/issues/238 are implemented. 

You can rise an issue to RoboBinding if you wish to. Once the two are implemented, you will have something like below:

@PresentationModel

class PresentationModel {

  @SubPresentationModel(preInitializingViews=false)

  public RadioGroupPM getRadioGroupPM() {

    return radioGroupPM;

  }

}

@PresentationModel

class RadioGroupPM {

  public boolean get/setRadio1(...){}

  ...

  public boolean get/setRadioN(...){}

} 

Cheers,

Hi Johnny,

Correct. Robobinding does not support parts of VM without Pre-initializing at the moment. Seems we discussed this somewhere before. Unless whole VM without Pre-initializing, views will be initialized with values from VMS. The choice at the moment is to implement those special parts in standard Android way.

Cheers, Cheng
