android - Navigate via back-button from child fragment back to parent activity -


i have main activity , 2 fragments. in main activity have navigation drawer navigates through fragments. handle button pressed this:

@override public void onbackpressed() {     if (getfragmentmanager().getbackstackentrycount() > 0) {         getfragmentmanager().popbackstackimmediate();     } else {         super.onbackpressed();     } }

after navigating between 2 fragments, when hit button, last fragment backstack. however, navigating fragment fragment should not possible.

more clarity:

i have 1 activity (with navigation drawer) , 2 fragments. navigation drawer can go both fragments many times want. when hit button, want go main_activity.xml.

when navigate through activities, best way use intents (if understood question):

intent intent = new intent(this, mainactivity.class); startactivity(intent);

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.
