问题 I am making a shopping list app, and I have two Fragments , a ProductListFragment and a ShoppingListFragment . I have ActionBar buttons to add elements to the List on ProductListFragment .

问题 For some reason after being shown an empty view for no matching items, my list view won't reappear after removing all text from the search view. Within my adapter class, AFAIK .clear() in mData.clear(); needs to change to something else but I don't know what to. ItemListAdapter class public class ItemListAdapter extends BaseAdapter implements Filterable { private List<Victoria> mData; private List<Victoria> mFilteredData; private LayoutInflater mInflater; private ItemFilter mFilter; public

问题 I am working on my final project in android-programming course (so I'm still pretty new). I'm building my own media player. I implemented a Drawer that contains the different media types (video, audio, stream etc.) and what I want is to have each clicked item load a fragment that will tackle the task. The first one I'm working on is the audio fragment. It is th esecond on the list but i think it'll e easier than the video. Anyway. when I click on "audio" (picture link) I get a null pointer
