JSONArray arr = new JSONArray(result);
String[] stocks = new String[arr.length()];

for(int i=0;i<arr.length();i++){

   JSONObject obj = arr.getJSONObject(i);
   mDatabase= FirebaseDatabase.getInstance().getReference().child("books");
   atabaseReference newBid=mDatabase.push();
   newBid.child("usr_id").setValue(obj.getString("user_id"));
   newBid.child("usr_fullNme").setValue(obj.getString("first_name")+" "+obj.getString("last_name"));
   newBid.child("usr_mobile").setValue(obj.getString("user_mobile"));
   newBid.child("usr_avatr").setValue(obj.getString("src"));

You can use a Hashmap and do the following:

Map<String, Object> userValues = new HashMap<>();
  userValues.put("usr_id", obj.getString("user_id"));
  userValues.put("usr_fullNme",obj.getString("first_name")+" "+obj.getString("last_name"));
  userValues.put("usr_mobile", obj.getString("user_mobile"));
  userValues.put("usr_avatr",  obj.getString("src"));

Then use setValue():


mDatabase= FirebaseDatabase.getInstance().getReference().child("books");
String newBid = mDatabase.push().getKey();
mDatabase.child(newBid).setValue(userValues, new DatabaseReference.CompletionListener() {
        @Override
        public void onComplete(DatabaseError databaseError, DatabaseReference databaseReference) {
           System.out.println(databaseError);
        }
    });

From the docs:

public void setValue (Object value, DatabaseReference.CompletionListener listener)

Set the data at this location to the given value. Passing null to setValue() will delete the data at the specified location. The native types accepted by this method for the value correspond to the JSON types:

  • Boolean
  • Long
  • Double
  • String
  • Map
  • List
