Pin several images at touch points - Android -

-

am trying place pins wherever user touches on imageview. assume map (like google maps) & user touches point, point a, , pin drawn @ point. then, user touches point b, pin (not same previous pin relocated!) needs drawn @ point b , on. right now, able draw pin @ point user touches on screen :

@override public void ondraw(canvas canvas) { ....     bitmap marker = bitmapfactory.decoderesource(getresources(),             r.drawable.icon_locationmarker);     canvas.drawbitmap(marker, mlasttouchx, mlasttouchy, null); ....      canvas.restore(); }

however, don't want relocate 1 pin across screen wherever user touches (which above code doing). want put several pins @ points wherever user touches. new android. please help.

eluvatar right, needs create list store mark. here's sample of code. remember, add list when motionevent either action_up or action_down only. otherwise, there full of point.

public arraylist<coordinate> pointslist;  @override public void ondraw(canvas canvas) { ....     bitmap marker = bitmapfactory.decoderesource(getresources(),             r.drawable.icon_locationmarker);     for(coordinate coor : pointslist){         canvas.drawbitmap(marker, coor.x, coor.y, null);     }  ....      canvas.restore(); }  public view.ontouchlistener mlistener = new view.ontouchlistener() {      @override     public boolean ontouch(view v, motionevent event) {          if (event.getaction() == android.view.motionevent.action_up) {             pointslist.add(new coordinate(event.getx(), event.gety()));         }          return false;     } };  class coordinate{     float x;     float y;     public coordinate(float x, float y){         this.x = x;         this.y = y;     } }

edit: change int x,y float x,y

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
