I am develop an app that can control a reading light, this reading light can be controlled via a built in control app or my app. The issue is I can not sync the toggle button state between the two. I have tried isChecked(), setText(), setTextOn/setTextOff, none works. Thanks

Here is my MainActivity:

import android.app.FragmentManager;
import android.app.FragmentTransaction;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;
import android.view.View;
import android.view.WindowManager;
import android.widget.Button;
import android.widget.TextView;

import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;


public class MainActivity extends AppCompatActivity implements PacioWebSocketListener.MessageListener 

 private static final boolean True = true;
 private static final boolean False = false;
 private final String TAG = "===MainActivity===";

 private PacioWebSocketListener pacioWebSocketListener = new PacioWebSocketListener();


 private JSONObject obj;
 private JSONObject argsObj;
 private JSONArray paramsArray;

 private String appName;
 private String commandName;
 private String eventName;


 private int READING_LIGHT_CHANGE;

 private Button sbCtrlButton;

 private FragmentManager fragmentManager = getFragmentManager();

 private SeatbackControlFragment seatbackControlFragment = new SeatbackControlFragment();


 @Override
 public void onMessageReceived(String mMessage) 

 try
 obj = new JSONObject(mMessage);
 argsObj = new JSONObject(obj.getString("args"));

 if(argsObj.has("params"))
 paramsArray = new JSONArray(argsObj.getString("params"));
 eventName = argsObj.getString("name");
 

 appName = obj.getString("app");
 commandName = obj.getString("command");

 if (appName.equals("events")) 
 if (commandName.equals("handleEvents")) 

 if(eventName.equals("PSS_READING_LIGHT_CHANGE"))
 READING_LIGHT_CHANGE = paramsArray.getInt(0);
 if(PSS_READING_LIGHT_CHANGE == 1)
 seatbackControlFragment.readingLight.setChecked(True);
 else 
 seatbackControlFragment.readingLight.setChecked(False);
 
 
 
 

 catch (JSONException e)
 e.printStackTrace();
 
 

 @Override
 protected void onCreate(Bundle savedInstanceState) 
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);
 getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
 pacioWebSocketListener.setPacioWebSocketListener(this);

 sbCtrlButton = findViewById(R.id.button);
 FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
 fragmentTransaction.add(android.R.id.content,seatbackControlFragment);
 fragmentTransaction.commit();

 sbCtrlButton.setOnClickListener(new View.OnClickListener() 
 @Override
 public void onClick(View v) 
 FragmentTransaction fragmentTransaction = getFragmentManager().beginTransaction();
 fragmentTransaction.replace(android.R.id.content, seatbackControlFragment);
 fragmentTransaction.addToBackStack(null);
 fragmentTransaction.commit();
 
 );
 

And this is my fragment:

import android.app.Activity;
import android.content.Context;
import android.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.CompoundButton;
import android.widget.ToggleButton;


public class SeatbackControlFragment extends Fragment

 public ToggleButton readingLight;
 private View view;
 private PacioWebSocketListener pacioWebSocketListener = new PacioWebSocketListener();

 @Override
 public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) 
 view = inflater.inflate(R.layout.fragment_seatback_control, container, false);
 readingLight = view.findViewById(R.id.reading_light);

 readingLight.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() 
 @Override
 public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) 
 if(isChecked)
 pacioWebSocketListener.ws.send(""app":"seatServices", "command":"readingLight", "args":"event":"on"");
 else 
 pacioWebSocketListener.ws.send(""app":"seatServices", "command":"readingLight", "args":"event":"off"");
 
 
 );

 return view;
