需要幫助導航抽屜

Question

我已經從https://developer.android.com/intl/es/samples/NavigationDrawer/res/drawable-mdpi/ic_drawer.html下載ic_drawer.png並將其粘貼到mipmap-hdpi,mipmap-mdpi,mipmap-xhdpi,。但我得到解決不了符號ic_drawer

actionBarDrawerToggle = new ActionBarDrawerToggle(
       this,     /* host Activity */ 
       drawerLayout,   /* DrawerLayout object */ 
       R.drawable.ic_drawer, /* nav drawer icon to replace 'Up' caret */ 
       R.string.drawer_open, /* "open drawer" description */ 
       R.string.drawer_close /* "close drawer" description */ 
     ); 

如何解決這一問題？由於

你應該把紋理貼圖的參考，而不是繪製

R.mipmap.ic_drawer
