title: Change Android Switch State
body: <p>I currently am developing an app that has a menu, and one of the options on the menu is "Settings" where the user can basically decide to turn off sounds and other things like that. I currently have two switches in the Settings activity. Here is the java code for the Settings activity so far:</p>
  
  <pre><code>import android.support.v7.app.ActionBarActivity;
  
  
  public class Options extends ActionBarActivity {
  private  Switch ding;
  private Switch countdown;
  public  boolean isDingChecked;
  public  boolean isCountdownChecked;
  public static final String PREFS = "examplePrefs";
  
  @Override
  protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_options);
  ding = (Switch) findViewById(R.id.switch1);
  ding.setOnCheckedChangeListener(new OnCheckedChangeListener() {
      public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
  
          SharedPreferences examplePrefs = getSharedPreferences(PREFS,0);
          Editor editor = examplePrefs.edit();
          editor.putBoolean("userMessage", isChecked);
          editor.commit();
  
          //System.out.println(examplePrefs.getBoolean("userMessage", isChecked));
          isDingChecked = examplePrefs.getBoolean("userMessage", isChecked);
          System.out.println(isDingChecked + " is ding checked");
          ding.setChecked(isDingChecked);
      }
  });
  
  countdown = (Switch) findViewById(R.id.switch2);
  countdown.setOnCheckedChangeListener(new OnCheckedChangeListener() {
      public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
          // do something, the isChecked will be
          // true if the switch is in the On position
          isCountdownChecked = isChecked;
  
      }
  });     
   }
   }
  </code></pre>
  
  <p>I am able to use the boolean values in my other activity, so the SharedPreference works fine. However, when I go back to my menu activity and go back to this options activity, the state of the switches goes back to its default values of being true, regardless of what the user states. Is there anyway I can fix this? </p>
  
  <pre><code>ding.setChecked(isDingChecked)
  </code></pre>
  
  <p>Isn't really doing anything I guess. I know I posted a question similar to this in the past, it's just that one hasn't had much activity and I've been working on this issue for quite some time. Thanks!</p>
