每次启用 SwitchCompat 按钮时如何运行操作？

有一个开关按钮 SwitchCompat，当它被启用时，应该会来一个本地通知。问题是如果你设置了时间，然后打开拨动开关，那么通知就会来，但是如果你让拨动开关打开并设置一个新的通知时间，直到你关闭并打开它才会来再次在拨动开关上。如何解决？据我了解，该程序只检查一次拨动开关是否打开？

活动代码片段：

public class AlarmActivity extends AppCompatActivity implements TimePickerDialog.OnTimeSetListener {

    private EditText mondayText;
    private SwitchCompat mondaySwitch;
    SharedPreferences sPref;
    String timeText = "";
    final String SAVED_TEXT = "saved_text";
    boolean switch_On_Off;
    public static final String PREFS_NAME = "Switch_On_Off_check";
    final Calendar c = Calendar.getInstance();

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

        mondayText = findViewById(R.id.monday_time);
        mondaySwitch = findViewById(R.id.switch_monday);

        // load SharedPref save text in mondayText and save switch On else Off
        loadText();
        loadSwitchCheck();

        mondaySwitch.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {

                startAlarm(c);
                saveSwitchCheck();

            }
        });


        mondayText.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                DialogFragment timePicker = new TimePickerFragment();
                timePicker.show(getSupportFragmentManager(), "time picker");
            }
        });


    }

    @Override
    public void onTimeSet(TimePicker view, int hourOfDay, int minute) {

        c.set(Calendar.HOUR_OF_DAY, hourOfDay);
        c.set(Calendar.MINUTE, minute);
        c.set(Calendar.SECOND, 0);
        updateTimeText(c);
    }

    private void updateTimeText(Calendar c) {

        // clean EditText time
        timeText = "";
        timeText += DateFormat.getTimeInstance(DateFormat.SHORT).format(c.getTime());
        mondayText.setText(timeText);
        saveText();

    }

    public void startAlarm(Calendar c) {

        AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
        Intent intent = new Intent(this, AlertReceiver.class);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 1, intent, 0);

        if (c.before(Calendar.getInstance())) {
            c.add(Calendar.DATE, 1);
        }
        alarmManager.setExact(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), pendingIntent);

    }

所以，我做了一个检查来打开/关闭开关（或者我想我做了），但现在通知总是来，布尔 OnOff 变量被完全忽略

更正的代码：

public class AlarmActivity extends AppCompatActivity implements TimePickerDialog.OnTimeSetListener {

    private EditText mondayText;
    public SwitchCompat mondaySwitch;
    SharedPreferences sPref;
    String timeText = "";
    final String SAVED_TEXT = "saved_text";
    boolean switch_On_Off;
    boolean OnOff;
    public static final String PREFS_NAME = "Switch_On_Off_check";
    final Calendar c = Calendar.getInstance();


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

        mondayText = findViewById(R.id.monday_time);
        mondaySwitch = findViewById(R.id.switch_monday);

        // load SharedPref save text in mondayText and save switch On else Off
        loadText();
        loadSwitchCheck();

        mondaySwitch.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {

                if (mondaySwitch.isChecked()) {

                    OnOff = true;
                    Toast.makeText(getApplicationContext(), "Включено", Toast.LENGTH_SHORT).show();

                } else {
                    OnOff = false;
                    Toast.makeText(getApplicationContext(), "Выключено", Toast.LENGTH_SHORT).show();
                }

                saveSwitchCheck();

            }
        });

        mondayText.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                DialogFragment timePicker = new TimePickerFragment();
                timePicker.show(getSupportFragmentManager(), "time picker");
            }
        });

    }

    @Override
    public void onTimeSet(TimePicker view, int hourOfDay, int minute) {

        c.set(Calendar.HOUR_OF_DAY, hourOfDay);
        c.set(Calendar.MINUTE, minute);
        c.set(Calendar.SECOND, 0);
        updateTimeText(c);

        if (OnOff = true) {
            startAlarm(c);
        } else {
            Toast.makeText(getApplicationContext(), "Включите", Toast.LENGTH_SHORT).show();
        }
    }

    private void updateTimeText(Calendar c) {

        timeText = "";
        timeText += DateFormat.getTimeInstance(DateFormat.SHORT).format(c.getTime());
        mondayText.setText(timeText);
        saveText();

    }

    public void startAlarm(Calendar c) {


        AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
        Intent intent = new Intent(this, AlertReceiver.class);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 1, intent, 0);

        if (c.before(Calendar.getInstance())) {
            c.add(Calendar.DATE, 1);
        }
        alarmManager.setExact(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), pendingIntent);

    }
