the question is: how can linearlayout requestfocus?  

  • note: close layouts, need focus.

i've tried

google : android scrollview focus edittext / elements / layout / onclick focus scroll , not work .

save last opened linearlayout in variable , close after user open new. or show more code.

edit

use scrolltoview(view view, scrollview scrollview), view linearlayout. linearlayout take maximum possible space in scrollview

public static void scrolltoview(view view, scrollview scrollview) {         scrolltoview(view, scrollview, 0);     }       public static void scrolltoview(final view view, final scrollview scrollview, int count) {         if (view != null && view != scrollview) {             count += view.gettop();             scrolltoview((view) view.getparent(), scrollview, count);         } else if (scrollview != null) {             final int finalcount = count;              new handler().postdelayed(new runnable() {                 @override                 public void run() {                     scrollview.smoothscrollto(0, finalcount);                 }             }, 200);         }     }

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.
