title: Saving state of checkbox and alarm
body: <p>I'm new to android and I need to make an app that starts an alarm when a check box is checked and keeps the state of the check box saved. I tried to use an int to save values of checkbox and start alarm but it doesn't work.</p>
  
  <pre><code>public int getValueC(String key) {
      SharedPreferences sharedPref = getPreferences(Context.MODE_PRIVATE);
      int value = sharedPref.getInt(key, 0);
      return value;
  }
  public void saveValueC(String key, int value) {
      SharedPreferences sharedPref = getPreferences(Context.MODE_PRIVATE);
      SharedPreferences.Editor editor = sharedPref.edit();
      editor.putInt(key, value);
      editor.apply();
  }
  @Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_a_d_q);
      Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
      setSupportActionBar(toolbar);
  
      final CheckBox checkBox1 = (CheckBox) findViewById(R.id.mc);
      final String keyC = "somekeyC";
      c = getValueC(keyC); 
  
      checkBox1.setOnClickListener(new View.OnClickListener() {
          @Override
          public void onClick(View view) {
  
              c++;
              saveValueC(keyC,c);
  
              if (c%2==0){
                  Toast ToastMessage = Toast.makeText(getApplicationContext(), "off", Toast.LENGTH_LONG);
                  //View toastView = ToastMessage.getView();
                  //toastView.setBackgroundColor(Color.YELLOW);
                  ToastMessage.show();
                  alarmManagers.cancel(pendingIntent);
              }
              else{
                  Toast ToastMessage = Toast.makeText(getApplicationContext(), "on", Toast.LENGTH_LONG);
                  //View toastView = ToastMessage.getView();
                  //toastView.setBackgroundColor(Color.YELLOW);
                  ToastMessage.show();
                  alarmManagers.setRepeating(AlarmManager.RTC,  calendar.getTimeInMillis(),2*60*1000,pendingIntents);
  
                  checkBox1.isChecked();
              }});
     if (c%2==0){
  
          Toast ToastMessage = Toast.makeText(getApplicationContext(), "Even number", Toast.LENGTH_LONG);
          //View toastView = ToastMessage.getView();
          //toastView.setBackgroundColor(Color.YELLOW);
          ToastMessage.show();
  
      }
      else{
  
          checkBox1.isChecked();
      }
  </code></pre>
  
  <p>I did not include the alarm manager and intent code because the alarm works fine. I just need to save value to check box and when it's checked; it should turn on the alarm and save the state of check box. When it's unchecked ; it should turn off the alarm and save the start of check box.</p>
  
  <p>I've spent hours trying to figure it out. If you know the issue, plz let me know. Thank you</p>
