java - Drawer, Fragment and Activities -


i have questions designing applications navigationdrawer.

i create application navigationdrawer composed of 1 activity , fragments. example have 4 fragments, , every fragment has actions.

which correct way implement that?

  1. adding actions activity?
  2. create other classes , call them mainactivity context/view?
  3. other?

any information these questions appreciated. need example or resource explaining correct way implement this.

anyone can help?

check google io 2014 source code idea of nav drawer implementation

https://github.com/google/iosched

all navigation , fragment transactions should done via main activity or activity holding fragments. kind of fragment - fragment communication should avoided. developer docs shows example of how handle fragment communication via activity using interfaces

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.
