All of the existing code examples utilize ListView and arrayAdapters for presenting the data and getting a reference to the document via QueryRow.
I would like to do something like what is being used in the GrocerySync example:
QueryRow row = (QueryRow) adapterView.getItemAtPosition(position);
final Document clickedDocument = row.getDocument();
String itemText = (String) clickedDocument.getCurrentRevision().getProperty("text");
I have also reviewed the QueryRow documentation and there appears to be a function GetDocument:
public String getDocumentId()
but I am a loss on how to access this method and get the resulting docID so I can update my rows recyclerView with data from the database. Here is the code fragment I am working in:
public class MainListFragment extends Fragment {
protected MyApplication app;
private RecyclerView mRecyclerView;
private Database getDatabase() {
app = (MyApplication) getActivity().getApplication();
return app.getDatabase();
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_list_main, container, false);
mRecyclerView = (RecyclerView) v.findViewById(R.id.my_recycler_view);
mRecyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));
mRecyclerView.setAdapter(new MyAdapter());
return v;
}
public class MyHolder extends ViewHolder {
TextView tv;
public MyHolder(View itemView) {
super(itemView);
tv = (TextView) itemView.findViewById(R.id.email_task_title);
}
}
private class MyAdapter extends RecyclerView.Adapter<MyHolder> {
private static final int EMPTY_VIEW = 10;
private class myRefreshTask extends AsyncTask<Void, Void, Void> {
@Override
protected Void doInBackground(Void... params) {
return null;
}
@Override
protected void onPostExecute(Void aVoid) {
notifyDataSetChanged();
super.onPostExecute(aVoid);
}
}
@Override
public MyHolder onCreateViewHolder(ViewGroup parent, int pos) {
View view;
view = LayoutInflater.from(parent.getContext())
.inflate(R.layout.email_list_item, parent, false);
return new MyHolder(view);
}
@Override
public void onBindViewHolder(MyHolder holder, int pos) {
Document row = getDatabase().getDocument(String.valueOf(getId()));
String id = row.getId();
new myRefreshTask().execute();
if (getItemCount() == 0) {
holder.tv.setText("No tasks scheduled.");
}
holder.tv.setText(id);
}
@Override
public int getItemViewType(int position) {
if (getDatabase().getDocumentCount() == 0) {
return EMPTY_VIEW;
}
return super.getItemViewType(position);
}
@Override
public long getItemId(int position) {
return super.getItemId(position);
}
@Override
public int getItemCount() {
return getDatabase().getDocumentCount();
}
@Override
public void registerAdapterDataObserver(RecyclerView.AdapterDataObserver observer) {
super.registerAdapterDataObserver(observer);
notifyDataSetChanged();
}
@Override
public void unregisterAdapterDataObserver(RecyclerView.AdapterDataObserver observer) {
super.unregisterAdapterDataObserver(observer);
}
}
}
This is exactly what I was looking for. I didn’t think anybody would have any code examples illustrating how to do this.
