Good afternoon to the community. I need your help to solve a novice problem like me, but that has me stuck.

In general, what I want is to send an entire data from a second class extended in BroacastReceiver to the main class Mainactivity.

The program I am using is the following program

Sorry for my frankness. I really do not ask you to solve the problem without doing anything but if they could be a bit simple in your expression I would appreciate it. I'm a novice in this programming, but this stage is only part of the project.

Waiting for an answer I thank you for your time.

If we edit the answer to the question Help with getter on android you did. We would only have to implement the method onReceive in onCreate and then activate / deactivate the button according to the state:

//..
private MusicIntentReceiver myReceiver;

@Override protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    final Button button = (Buttton)findViewById(R.id.id_boton);

    myReceiver = new MusicIntentReceiver(){

        @Override
        public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals(Intent.ACTION_HEADSET_PLUG)) {
            int state = intent.getIntExtra("state", -1);
            switch (state) {
            case 0:
            // desactivamos el buton
               button.setEnabled(false);
                break;
            case 1:
            // activamos
               button.setEnabled(true);
                break;
            default:
                Log.d(TAG, "I have no idea what the headset state is");
            }
        }
   };
}

@Override public void onResume() {
    IntentFilter filter = new IntentFilter(Intent.ACTION_HEADSET_PLUG);
    registerReceiver(myReceiver, filter);
    super.onResume();
}
