how I can get the height of a screen in android? -


i'am trying develop app item goes down , when touch screen rises, have 2 smarthphones , 1 larger other , want greater speed @ item dropped in small. class (no extends activity)

public class vistajuego extends view{ grafico item; public vistajuego(context context, attributeset attrs) {     super(context, attrs);  item = new grafico(this, drawablefaba); } @override protected void onsizechanged(int w, int h, int oldw, int oldh) {     super.onsizechanged(w, h, oldw, oldh);      item.setposx(w/2);     item.setposy(h/2);     item.setheightcanvas(h);     item.setwidthcanvas(w);     height=h;     width=w;       if(h<=800){         item.setincreasey(7);//increase speed posy x 7     }else{         item.setincreasey(15);//increase speed posy x 7     } }

and can't use displaymetrics because class not extends activity. idea?? pleaseee

you can still use displaymetrics. simple way pass in context. since view, don't need that- it's done you. use getcontext() activity, can call function on activity need- such getcontext().getresources().getdisplaymetrics();

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
