New Nested Category Screen

[wolfsolver]

I made some check and develop a mockup for multilevel category entry..

Comment on Usability are welcome

Here a simple idea.

@guanlisheng did you have any suggestions?

First switch off use method like previous one, set on use _self to handle parent as children (so parent can have total)
Second switch show selection view vs report view

@guanlisheng I need your support to convert from sample project into AMMEX. Take a look to my latest deploy on https://github.com/wolfsolver/exampleNestedCategory

I try to adapt sample code into AMMEX structure. Previus category management use this this kind of declaration

public class CategoryListFragment
    extends BaseExpandableListFragment
    implements LoaderManager.LoaderCallbacks<Cursor> 

and the following hierarchy: BaseExpandableListFragment --> ExpandableListFragment --> Fragment

I need to switch from ExpandableList to new layout based on two piece of layout:

• data_activity.xml (need to be renamed with NestedCategoryFragment ==> This has the adapter binded
• item_activity.xml (need to be renamed with NestedCategoryItemFragment ==> where layout is define with convertView = LayoutInflater.from(DataActivityComplex.this).inflate(R.layout.data_item, null);

This suggest to have this new class inside project:

• NestedCategoryListFragmentNew extends BaseMultiLevelListFragment implements LoaderManager.LoaderCallbacks<Cursor>
• BaseMultiLevelListFragment extends BaseListFragment

and put all logic for generic multilevel into BaseMultiLevelListFragment and all specifc logic into NestedCategoryListFragmentNew

It's correct? do you have any suggestion?

My Todo list:

• force always use of new model
• delete unused code where used by getUseNestedCategory() remove also if
• substitute reference of QueryCategorySubCategory with new QueryNestedCategory
• remove unnecessary field subcategory in some method (or replace with null)
• remove unnecessary files
• remove switch from preference
• remove unrelevant subcategory field from all query
