Body
<p>I have a PreferenceActivity in which there is a <code>CheckboxPreference</code>. I would like clicking on CheckboxPreference enable or disable Mobile Data, so I wrote this code. </p> <pre><code>//Outside of Methods void turnData(boolean ON) throws Exception { final ConnectivityManager conman = (ConnectivityManager) getApplicationContext().getSystemService(Context.CONNECTIVITY_SERVICE); final Class conmanClass = Class.forName(conman.getClass().getName()); final java.lang.reflect.Field iConnectivityManagerField = conmanClass.getDeclaredField("mService"); iConnectivityManagerField.setAccessible(true); final Object iConnectivityManager = iConnectivityManagerField.get(conman); final Class iConnectivityManagerClass = Class.forName(iConnectivityManager.getClass().getName()); final Method setMobileDataEnabledMethod = iConnectivityManagerClass.getDeclaredMethod("setMobileDataEnabled", Boolean.TYPE); setMobileDataEnabledMethod.setAccessible(true); setMobileDataEnabledMethod.invoke(iConnectivityManager, ON); } //In the onCreate final boolean o = false; boolean mobileDataEnabled = false; ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE); try { Class cmClass = Class.forName(cm.getClass().getName()); Method method = cmClass.getDeclaredMethod("getMobileDataEnabled"); method.setAccessible(true); mobileDataEnabled = (Boolean)method.invoke(cm); } catch (Exception e) { } if(mobileDataEnabled) { ((CheckBoxPreference)Data).setChecked(true); //The Mobile Data are enabled Data.setSummary("Mobile Data enabled"); dati = true; } else { //The Mobile Data are disabled ((CheckBoxPreference)Data).setChecked(false); try { turnData(mobileDataEnabled); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } Data.setSummary("Mobile Data disabled"); dati = false; } Data.setOnPreferenceClickListener( new OnPreferenceClickListener() { public boolean onPreferenceClick(Preference preference) { if (dati==true) { Data.setSummary("Mobile Data enabled"); dati = false; } else if (dati==false){ try { //The problem is here //What should I put in the parentheses? turnData(o); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } Data.setSummary("Mobile Data disabled"); dati = true; } return false; } }); </code></pre> <p>The problem, as noted in the comments in the code, is what to put in the parentheses when calling the method. I apologize if the question may seem trivial **but please bear with me. I'm beginner.</p>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
