Time：08-01

I mixed things up. The initial error I had was this MainActivity.java:130: error: incompatible types: List<com.kuroniczstudio.splashscreen.CategoryItem> cannot be converted to List<com.kuroniczstudio.splashscreen.model.CategoryItem> allCategoryList.add(new AllCategory(1,"VIP Hour", homeCatListItem1)); While try to fix it that was when things started getting confusing. So I am still having this error

CodePudding user response：

The error itself is telling you where you are messing up. You have 2 CategoryItem classes in your project with the following hierarchies:

  1. com.kuroniczstudio.splashscreen.CategoryItem
  2. com.kuroniczstudio.splashscreen.model.CategoryItem

You're trying to use both these which is creating this conflict. Make sure you are using only one class.

CodePudding user response：

In your application you have TWO classes called CategoryItem. One has the full name:

com.kuroniczstudio.splashscreen.CategoryItem

The other has the full name:

com.kuroniczstudio.splashscreen.model.CategoryItem

They are different classes, and you cannot convert from one class to the other one.

We cannot tell from the code that you have shown us why this is happening. For a start, you haven't show us both versions of CategoryItem. And you have left out all of the package statements. (So we can't tell which version of CategoryItem the AllCategory constructor expects ...)

But the compilation error message clearly proves that it is happening.

You probably shouldn't have two CategoryItem classes at all ...
