Вот мой полный код.FireBase UI Android FirebaseRecyclerAdapter error
public class RemovedSpotsActivity extends AppCompatActivity {
private FirebaseRecyclerAdapter mAdapter;
List<RemovedSpotItems> removedSpots;
@Override
protected void onCreate(Bundle s) {
super.onCreate(s);
setContentView(R.layout.removed_spots_list);
removedSpots=new ArrayList<>();
Firebase.setAndroidContext(this);
final Firebase ref = new Firebase(getResources().getString(R.string.firebase_url));
RecyclerView recycler = (RecyclerView) findViewById(R.id.recycler_view);
recycler.setHasFixedSize(true);
recycler.setLayoutManager(new LinearLayoutManager(this));
String key=ref.child("markers").getKey();
Log.v("KEY_ENTERED",key);
ref.child("markers").addChildEventListener(new ChildEventListener() {
@Override
public void onChildAdded(DataSnapshot dataSnapshot, String s) {
Map<String, Object> newPost = (Map<String, Object>) dataSnapshot.getValue();
System.out.println("Description: " + newPost.get("description"));
System.out.println("Status: " + newPost.get("status"));
RemovedSpotItems items = new RemovedSpotItems();
items.setDescription((String) newPost.get("description"));
items.setStatus((String) newPost.get("status"));
removedSpots.add(items);
}
public void onChildChanged(DataSnapshot dataSnapshot, String s) { }
public void onChildRemoved(DataSnapshot dataSnapshot) { }
public void onChildMoved(DataSnapshot dataSnapshot, String s) { }
public void onCancelled(FirebaseError firebaseError) { }
});
mAdapter = new FirebaseRecyclerAdapter<RemovedSpotItems, ReomvedSpotViewHolder>(RemovedSpotItems.class, R.layout.removed_spots_row, ReomvedSpotViewHolder.class,ref) {
@Override
protected void populateViewHolder(ReomvedSpotViewHolder viewHolder, RemovedSpotItems model, int position) {
super.populateViewHolder(viewHolder, model, position);
final int i = 0;
Log.v("TAG","populating");
RemovedSpotItems model1=removedSpots.get(i);
viewHolder.description.setText(model1.getDescription());
viewHolder.email.setText(model1.getStatus());
}
};
recycler.setAdapter(mAdapter);
}
Я попробовал свой уровень лучше, но не смог определить ошибку я думаю, что нет никаких проблем в получении данных, как это правильно извлекаются, как мы можем видеть в журнале есть некоторая проблема с FirebaseRecyclerAdapter.
RemovedSpotItems.java
public class RemovedSpotItems {
public String description;
public String cleanedBy;
public String owner;
public String status;
public String getDescription()
{
return description;
}
public void setDescription(String description)
{
this.description=description;
}
public String getCleanedBy()
{
return cleanedBy;
}
public void setCleanedBy(String cleanedBy)
{
this.cleanedBy=cleanedBy;
}
public String getStatus()
{
return status;
}
public void setStatus(String status)
{
this.status=status;
}
public String getOwner() { return owner;}
public void setOwner(String owner)
{
this.owner=owner;
}
}

Не видя образца вашего JSON (как текст, скриншоты JSON довольно бесполезны), невозможно сказать, что вызывает это. Нам также нужно увидеть 'RemovedSpotItems', так как это то, к чему вы пытаетесь сопоставить JSON. См. Http://stackoverflow.com/help/mcve, как сделать это проще всего для нас, чтобы помочь вам. –
