From documentation https://developer.android.com/reference/android/widget/Adapter.html#getView(int,android.view.View android.view.ViewGroup)

Get a View that displays the data at the specified position in the data set. You can either create a View manually or inflate it from an XML layout file. When the View is inflated, the parent View (GridView, ListView...) will apply default layout parameters unless you use inflate(int, android.view.ViewGroup, boolean) to specify a root view and to prevent attachment to the root.

parent - The parent that this view will eventually be attached to

ViewGroup helps to hold multiple Views together.

E.g. You can consider ViewGroup as your Layout and TextView as the View.

That means your ViewGroup contains View as a TextView.
