android preferences - CheckBoxPreference group that act like Radio -


I had to launch more than one checkbox on the same screen which would act like a radio list, I saw some implementation of it, But finally I wrote some of my own. Maybe it will help someone.

1) Create a group class, such as: 

  public class Checkbox field group {Private list & lt; Checkbox presentation & gt; MGroup; Public Checkbox PrefricaSGroup (Primary Manager Manager, String [] key) {mGroup = New Arrestist & lt; Checkbox projection & gt; (Keys.length); For (int i = 0; i & lt; keys; lamps; i ++) {last checkbox presentation cbx = (checkbox presentation) manager.findPreference (key [i]); Cbx.setOnPreferenceClickListener (New OnPreferenceClickListener () {public boolean onPreferenceClick (Priority Priority) {onCheckBoxClick (cbx); Back to True;}}); MGroup.add (cbx); }} Private zero on checkbox, checkbox (new checked) {checkbox checked checked = zero; (Checkbox presentation item: mgut) {if (item! = New check & item checked ()) {old che = item; break; }} If old check! =) Old Chekhed. Set check (wrong); }}   
 2) Provide with an array of strings (string [] key) so that he can search for preferences.  
 3) Use it like this:    Increases the public frozen square settings preferences interface {Private Static Checkbox Proprietary Group Mellert Group; Override public null on @reate (bundle saved instainstate) {super.naught (savedinstenstate); AddPreferencesFromResource (R.xml.preferences_screen_notifications); PreferenceManager.setDefaultValues ​​(getActivity (). GetApplicationContext (), R.xml.preferences, false); PreferenceManager pm = getPreferenceManager (); MAlertGroup = New checkbox presentation group (pm, getResources (). GetStringArray (R.RA.PREF_Watchbox)); }}   
 Where  pref_checkboxes  is my string array checkbox key:  
  & lt; String-array name = "pref_checkboxes" & gt; & Lt; Items & gt; Pref_cbx1 & lt; / Item & gt; & Lt; Items & gt; Pref_cbx2 & lt; / Item & gt; & Lt; Items & gt; Pref_cbx3 & lt; / Item & gt; & Lt; Items & gt; Pref_cbx4 & lt; / Item & gt; & Lt; / String array & gt;

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
