android - How can I save the ListView's scroll position -


how can save listview's scroll position when choose 1 item in listview, , want return in same listview .

suppose have 2 fragments – listfragment , someotherfragment. replace listfragment someotherfragment.

    fragmentmanager manager = getfragmentmanager();     fragmenttransaction transaction = manager.begintransaction();      transaction.replace(r.id.content_frame, fragment);     transaction.addtobackstack(null);     transaction.commit();

the best solution know

// save listview state (= includes scroll position) parcelable

parcelable state = listview.onsaveinstancestate();

// restore previous state (including selected item index , scroll position)

listview.onrestoreinstancestate(state);

you can restore last saved position after setting adapter -

// save listview state (= includes scroll position) parceble parcelable state = listview.onsaveinstancestate();  // e.g. set new items listview.setadapter(adapter);  // restore previous state (including selected item index , scroll position) listview.onrestoreinstancestate(state);

you can refer here more details.

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.
