Im trying to get list of strings from a child and store it in a list of string , but idk what is wrong it is not getting any data from firebase at all
Here is the Data Fomat in Firebase Real Time Data Base
{
"art": [
{
"MrIncredibleArt": "stringexample4"
},
{
"GhostFace": "stringexample5"
},
...
],
"nsfw": [
{
"AnyLoser1": "stringtrollface1"
},
{
"AnyLoser2": "stringexample2"
},
...
]
}
Here is the method which get the data from firbase and store it in a list of string
private List<String> initAsciiArts_Meme() {
DatabaseReference databaseRef = FirebaseDatabase.getInstance().getReference().child("art");
List<String> dataList = new ArrayList<>();
databaseRef.addListenerForSingleValueEvent(new ValueEventListener() {
@Override
public void onDataChange(@NotNull DataSnapshot dataSnapshot) {
for (DataSnapshot memeSnapshot : dataSnapshot.getChildren()) {
for (DataSnapshot kvpSnapshot : memeSnapshot.getChildren()) {
String key = kvpSnapshot.getKey();
String value = kvpSnapshot.getValue(String.class);
Log.i("Firebase_Info", key + ": '" + value + "'");
dataList.add(value);
}
}
}
@Override
public void onCancelled(@NotNull DatabaseError databaseError) {
// Handle any errors that may occur
Log.e("Firebase", "Failed to retrieve art data: " + databaseError.getMessage());
Toast.makeText(requireContext(), "Failed to retrieve art data: " + databaseError.getMessage(), Toast.LENGTH_SHORT).show();
}
});
return dataList;
}
Here is the OnCreate
public class MemeFragment extends Fragment {
List<String> asciiArts = new ArrayList<>();
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.meme_fragment, container, false);
asciiArts = initAsciiArts_Meme();
try {
adapter= new MemeAdapter_Meme(asciiArts, requireContext(), this);
recyclerView.setHasFixedSize(true);
recyclerView.setAdapter(adapter);
} catch (Exception e) {
e.printStackTrace();
// Handle the exception here
}
return view;
}
