Saya masih mencoba untuk fokus pada recyclerview. Saya memiliki daftar larik, yang saya gunakan untuk menginisialisasi tampilan pendaur ulang.
Bagaimana saya bisa menambahkan item baru ke recycler view post mengatur adaptor dan layoutmanager?
private void initData() {
mItems = new ArrayList<String>();
for (int i = 0; i < ITEMS_COUNT; i++) {
mItems.add("Item " + (i + 1));
}
}
private void initRecyclerView() {
mRecentRecyclerView = (RecyclerView) findViewById(R.id.recentrecyclerView);
mRecentRecyclerView.setHasFixedSize(true);
mRecentLayoutManager = new LinearLayoutManager(this);
mRecentRecyclerView.setLayoutManager(mRecentLayoutManager);
mAdapter = new RecyclerView.Adapter<CustomViewHolder>() {
@Override
public CustomViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.notice_snippet
, viewGroup, false);
return new CustomViewHolder(view);
}
@Override
public void onBindViewHolder(CustomViewHolder viewHolder, int i) {
viewHolder.noticeSubject.setText(mItems.get(i));
}
@Override
public int getItemCount() {
return mItems.size();
}
};
mRecentRecyclerView.setAdapter(mAdapter);
private class CustomViewHolder extends RecyclerView.ViewHolder {
private TextView noticeSubject;
public CustomViewHolder(View itemView) {
super(itemView);
noticeSubject = (TextView) itemView.findViewById(R.id.notice_subject);
}
}
Jadi pada dasarnya setelah I initdata()
dan initRecyclerView()
, bagaimana cara menambahkan item baru ke RecyclerView ??
