android - action bar icon keep showing back icon -


i'm literally new in developing android apps. project using navigation drawer between fragments. tried custom drawer tutorial http://www.tutecentral.com/android-custom-navigation-drawer/ , got error. in application, in action bar, keeps showing icon instead default icon.

this url before-after image of actionbar : http://oi58.tinypic.com/2ahsbys.jpg

here code i'm confused of (pretty same tutorial, tell me if there's missed)

    getsupportactionbar().setdisplayhomeasupenabled(true);     getsupportactionbar().sethomebuttonenabled(true);      mdrawertoggle = new actionbardrawertoggle(this, mdrawerlayout,             r.drawable.ic_drawer, r.string.navigation_drawer_open,             r.string.navigation_drawer_close) {         public void ondrawerclosed(view view) {             getsupportactionbar().settitle(mtitle);             invalidateoptionsmenu(); // creates call             // onprepareoptionsmenu()         }          public void ondraweropened(view drawerview) {             getsupportactionbar().settitle(mdrawertitle);             invalidateoptionsmenu(); // creates call             // onprepareoptionsmenu()         }     };

if delete setdisplayhomeasupenabled, icon gone can't click somewhere display drawer, have slide it. please refer me if has solved it. many thanks.

*i have changed r.drawable.ic_drawer other drawable icons had no effects.

try setting theme activity in manifest file , inside styles.xml set drawable homeasupindicator theme

<style name="customtheme" parent="@style/widget.appcompat.actionbar">       <item name="homeasupindicator">@drawable/ic_drawer</item>  </style>

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.
