android - Losing ACTION_DOWN parameters when InterceptTouchEvent -

-

i have parent view should follow finger on touch , child view inside clickable. used onintercepttouchevent decide if have consume touch event on parent or child comparing touch distance before action_up.

obviously used "retrun false" on action_down in onintercepttouchevent (because propagate event before calculations) unfortunately ontouch loses action_down.

the question how can initialize parameters (as initial position of parent view) ontouch (not onintercepttouchevent)?

footnote: reason have write ontouch inline other codes have implemented onintercepttouchevent inside object definition.

a part of object definition:

boolean mmisbeingdragged;  float mlastx; float mstartx; int mtouchslop=viewconfiguration.get(getcontext()).getscaledtouchslop();  @override public boolean onintercepttouchevent(motionevent event) {      switch (event.getaction()) {         case motionevent.action_down:             mlastx = event.getx();             mstartx = mlastx;            break;          case motionevent.action_move:             float x = event.getx();             float y = event.gety();             float xdelta = math.abs(x - mlastx);              float xdeltatotal = x - mstartx;             if (math.abs(xdeltatotal) > mtouchslop) {                 mmisbeingdragged = true;                 mstartx = x;                 return true;             }             break;          case motionevent.action_cancel:          case motionevent.action_up:             mmisbeingdragged = false;             break;     }      return false; }

and ontouch defined outside of object (inline program)

    myview.setontouchlistener(new ontouchlistener()      {         float curx=0;         float oldx;         float startx;         float delta=0;         float togo;         boolean misbeingdragged=false;         int mtouchslop=viewconfiguration.get(getactivity()).getscaledtouchslop();          @override          public boolean ontouch(final view v, motionevent event)          {             switch (event.getaction()) {             case motionevent.action_down:             //here prblem! how initialize startx?              case motionevent.action_move:                  curx = event.getrawx();                 delta=curx-startx;                 togo=oldx+delta;                  if (math.abs(delta) > mtouchslop) {                     misbeingdragged=true;                     followfingerfunction(v,togo)                     return true;                 }                 break;                  case motionevent.action_up:                     if (!misbeingdragged){v.performclick();}                 break;         }             return true;     }     });

just expose mstartx activity. ( know not perfect seems ok). 

class parentview extends viewgroup (or other viewgroup) {     int startx;     public int getstartx(){         return startx;     } }

// after call getstartx() activity.

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.
