I was using Nested Recycler View to show that forms. I need to show questions and their options in a RecyclerView. For that I have used a recycler View to show questions and then I have used a recyclerView inside adapter of the main adapter. So that I can show its options like radios, checkboxs or TextView? Here I have used MultiView Recycler View
Here is the JSON Response
{
"fields": [
{
"id": 29,
"field_type": "checkbox-group",
"label": "Checkbox group",
"subtype": null,
"required": false,
"values": [
{
"id": 39,
"form_field": 29,
"label": "Option 1",
"value": "option-1"
},
{
"id": 40,
"form_field": 29,
"label": "Option 2",
"value": "option-2"
},
{
"id": 41,
"form_field": 29,
"label": "Option 3",
"value": "option-3"
}
,
{
"id": 42,
"form_field": 29,
"label": "Option 4",
"value": "option-4"
}
]
},
{
"id": 30,
"field_type": "radio-group",
"label": "Radio group",
"subtype": null,
"required": false,
"values": [

"value": "option-2"
},
{
"id": 42,
"form_field": 30,
"label": "Option 3",
"value": "option-3"

},
{

And Also the Model classes are here
public class ModelData {
String title;
String id;
List<ModelValues> categoryItemList;
public ModelData(String title, String id, List<ModelValues> categoryItemList) {
this.title = title;
this.id = id;
this.categoryItemList = categoryItemList;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public List<ModelValues> getCategoryItemList() {
return categoryItemList;
}
public void setCategoryItemList(List<ModelValues> categoryItemList) {
this.categoryItemList = categoryItemList;
}
}
All are working well but I'm unable to get selected data from each View's on Click of submit button.
