java - "Redraw" LinearLayout view to change option -


i'm trying change attribute custom linearlayout class, set option class with:

mybuilder option = new mybuilder.builder() .image(...) .setcardradius(...) .build());

than call in mainactivity

myobject obj = (myobject) findviewbyid(r.id.myobject);  obj.init(context, option);

but if call multiple times obj.init(...) different option builder has old value setted view cannot change attribute correctly.

so question is: can reset builder o linearlayout before initializate new object?

this linearlayout.java:

public class myobject extends linearlayout{     cardview card;     imageview image;     float cardradiusattr;     view rootview;     attributeset attributeset;      public void init(final context context, final mybuilder option){         if(option != null)         {          /*         attribute xml          */             typedarray ta = context.obtainstyledattributes(attributeset, r.styleable.card, 0, 0);             try {                 cardradiusattr = ta.getdimension(r.styleable.card_c_cardradius, option.getcardradius());              } {                 ta.recycle();             }          /*         set xml object.          */             card = (cardview) findviewbyid(r.id.card);             image = (imageview) findviewbyid(r.id.image);              card.setradius(cardradiusattr);              /**              * check if option set              */             if (option.isimage() != null) {                //set image              }         }else{             log.e("initialization", "option view not initialize!");         }     }       public myobject(context context, attributeset attrs) {         super(context, attrs);         /*         inflater custom layout view.          */         layoutinflater inflater = (layoutinflater) context                 .getsystemservice(context.layout_inflater_service);         rootview = inflater.inflate(r.layout.card, this, true);         attributeset = attrs;     }       @override     protected void onfinishinflate() {         super.onfinishinflate();     }  }

this mybuilder.java

public class mybuilder {     private int mimage;     private float mcardradius = 4f;      private mybuilder(builder builder)     {         mimage = builder.mimage;         mcardradius = builder.mcardradius;     }      public static class builder{         private int mimage;         private float mcardradius = 4f;          public builder setcardradius(float radius)         {             if(radius <= 0)             {                 log.e("cardradius", "impossible set card radius lower 0! please check it");             }             else {                 mcardradius = radius;             }             return this;         }          public builder image(int image) {              if(image == 0)             {                 log.e("image", "impossible set image 0! please check it");             }             else {                 mimage = image;             }             return this;         }          public mybuilder build() {             return new mybuilder(this);         }      }      public int getimage() {         return mimage;     }      public float getcardradius() {         return mcardradius;     } }

i found issue.

in init method of myobject have clean view after previous use.

in particular case, first, pass 1 set of options. based on them, view adjusting visibility of controls (making button1, button2, etc. visible). when pass another set of options - have erase changes have been made before. (i.e. hide button1, button2, etc. , let view adjust visibility of controls once again)

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -

i'm working on app using core data , nsfetchedresultcontroller many reasons switch use realm. saw there "realm version" of nsfetchedresultcontroller on github wouldn't compatible current code using core data. the view controller displaying list of people same school, address book. list sublist of people studied in same city. so thinking make 1 unique request database retrieve list of people , filter locally list within 1 dictionary per school [string: anyobject] string section name within tableview , anyobject array of people. first solution, make nsfetchedresultcontroller each school predicate filtering location. delete actions etc.. handled delegates -> not compatible realm create dictionaries , update them each actions... -> works realm it's annoying code. any better solution? edit: i need clarify request: i'd write class inherit uitableviewcontroller. this class has list of people sorted in alphabetical order the tableview has ...
