Nativescript - raddataform datepicker in Android

Question

我正在使用raddataform中的datepicker（使用javaScript的nativescript） - 当我选择2018年12月31日时，日期点数以以下格式显示日期-MON，31.12如何将其更改为更可读的格式？最好是mm/dd/yyyy这仅在Android中发生 - 在iOS中，它更可读。有什么建议吗？

<df:EntityProperty name="prdate" index="3" displayName="Date *" hintText="Enter Date *">
    <df:EntityProperty.editor>
        <df:PropertyEditor type="DatePicker">
            <df:PropertyEditor.propertyEditorStyle>
                <df:PropertyEditorStyle
                        labelHidden="true" labelWidth="0"
                        ios:labelFontName="Times New Roman" android:labelFontName="sans-serif-light"/>
            </df:PropertyEditor.propertyEditorStyle>
        </df:PropertyEditor>
    </df:EntityProperty.editor>
    <df:EntityProperty.validators>
        <df:NonEmptyValidator errorMessage="Please enter a date"/>
    </df:EntityProperty.validators>
</df:EntityProperty>

datePicker中更改格式仍然是一个开放的功能请求，但是在同一问题中已经显示了一个解决方法。
