No setter / field to warn Firebase Database Get data Set Listview

Question

No setter / field to warn Firebase Database Get data Set Listview

I'm just trying to populate data from a Firebase database into my list. Do the logs show that the data is being extracted, but the adapter will not set the values in the text in one list item in the list? All he says is "No setter / field for INSERT VALUE ." This makes me think that I did not have the correct settings, but cars were created in Android Studio. I don’t know what is missing here. Any help is appreciated.

NODE OBJECT

package com.megliosolutions.ipd.Objects;

import android.graphics.Bitmap;

/**
 * Created by Meglio on 6/13/16.
 */
public class NodeObject {


public String mStaticAddress;
public String mLat;
public String mLong;

public NodeObject(){
    //needed for firebase
}

public NodeObject(String address, String lat, String Long){
    this.mStaticAddress = address;
    this.mLat = lat;
    this.mLong = Long;
}

public String getmStaticAddress() {
    return mStaticAddress;
}

public void setmStaticAddress(String mStaticAddress) {
    this.mStaticAddress = mStaticAddress;
}

public String getmLat() {
    return mLat;
}

public void setmLat(String mLat) {
    this.mLat = mLat;
}

public String getmLong() {
    return mLong;
}

public void setmLong(String mLong) {
    this.mLong = mLong;
}
}

STATIC LISTADAPTER

/**
 * Created by Meglio on 6/14/16.
 */
public class StaticListAdapter extends ArrayAdapter<NodeObject> {
public static String TAG = StaticListAdapter.class.getSimpleName();
public Context mContext;
public List<NodeObject> mNodes;

public class ViewHolder {
    TextView mStaticAddress;
    TextView mLAT;
    TextView mLONG;

}

@Override
public int getCount() {
    return mNodes.size();
}

public StaticListAdapter(Context context, List<NodeObject> objects) {
    super(context, R.layout.activity_main, objects);
    this.mContext = context;
    this.mNodes = objects;
}

public View getView(int position, View convertView, ViewGroup parent) {
    ViewHolder holder = new ViewHolder();
    NodeObject node = mNodes.get(position);
    if (convertView == null) {
        convertView = LayoutInflater.from(this.mContext).inflate(R.layout.node_item, null);
        holder.mLONG = (TextView) convertView.findViewById(R.id.node_item_LONG);
        holder.mStaticAddress = (TextView) convertView.findViewById(R.id.node_item_IP);
        holder.mLAT = (TextView) convertView.findViewById(R.id.node_item_LAT);
        convertView.setTag(holder);
    } else {
        holder = (ViewHolder) convertView.getTag();
    }
    holder.mStaticAddress.setText(node.getStaticAddress());
    holder.mLONG.setText(node.getLongitude());
    holder.mLAT.setText(node.getLatitude());

    return convertView;
}
}

MAINACTIVITY

public class MainActivity extends AppCompatActivity {

public static String TAG = MainActivity.class.getSimpleName();

            });

@Override

    MenuInflater inflater = getMenuInflater();

    mAuth.signOut();
    Intent intent = new Intent(MainActivity.this, Login.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    Toast.makeText(getApplicationContext(), "Logging Out.", Toast.LENGTH_SHORT).show();
    startActivity(intent);

}

    //AlertDialog
    final AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(this);

    dialogBuilder.setTitle("Dude, assign something...");

    LayoutInflater inflater = this.getLayoutInflater();

    View dialogView = inflater.inflate(R.layout.main_add_node_dialog, null);

    dialogBuilder.setView(dialogView);

    final EditText editText = (EditText)
            dialogView.findViewById(R.id.static_et);
    dialogBuilder.setPositiveButton("Assign", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            static_ip = editText.getText().toString();
            String ip = static_ip;
            node = new NodeObject(ip, lat, mLong);
            mDatabase.child("nodes").child(currentUser).push().setValue(node);
            Toast.makeText(getApplicationContext(), "Static IP: " + static_ip + " assigned!"
                    , Toast.LENGTH_SHORT).show();
        }
    }).
            setNegativeButton("Or Not...", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    Toast.makeText(getApplicationContext(), "Fine, nvm then..."
                            , Toast.LENGTH_SHORT).show();
                }
            });

    dialogBuilder.create().show();
}




}

Debugging shows that I can get all the client side. Magazines also show this.

Firebase, Java:

public class NodeObject {
    public String staticAddress;
    public String lat;
    public String lon;

    public NodeObject(){
        //needed for firebase
    }

    public NodeObject(String address, String lat, String lon){
        this.staticAddress = address;
        this.lat = lat;
        this.lon = lon;
    }
}

JSON.

As a note, be aware that your naming is usually contrary to the convention. As a rule, prefixed variables mare private member variables that are accessible and mutated by public methods (like yours). A.
