android - NavigationDrawer activity doesn't keep keyboard's state on orientation change -


i created sample project using android studio: create new project -> navigation drawer activity. in testing purposes, content fragmentcontains single edittext widget.

in androidmanifest have line main activity:

android:windowsoftinputmode="stateunchanged|adjustresize"

odd behavior: if launch app in portrait mode, open soft keyboard (by tapping on edittext) , rotate device landscape mode... keyboard disappears reason. if create same project no navigationdrawer (just activity + fragment) keyboard remains visible (as expected stateunchanged property).

did know reason of such behavior? want keep keyboard expanded after switching landscape mode (if opened in portrait). can track keyboard state , via special flag restore visibility when needed programmatically, know. wonder why native tools don't work navigationdrawer.

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.
