右上角的导航抽屉图标显示汉堡图标的后退箭头图标

Question

我用导航抽屉活动创建了一个新的Android应用程序.当我执行应用程序时,右上角的图标显示后箭头,但它必须是3行的图标.

图标R.drawable.ic_drawer就是这个

在NavigationDrawerFragment类中.

// ActionBarDrawerToggle ties together the the proper interactions
    // between the navigation drawer and the action bar app icon.
    mDrawerToggle = new ActionBarDrawerToggle(
            getActivity(),                    /* host Activity */
            mDrawerLayout,                    /* DrawerLayout object */
            R.drawable.ic_drawer,             /* nav drawer image to replace 'Up' caret */
            R.string.navigation_drawer_open,  /* "open drawer" description for accessibility */
            R.string.navigation_drawer_close  /* "close drawer" description for accessibility */
    ) 

当我执行应用程序时,我正在右侧显示箭头图标.

选择后,Icon也是一样的.

我现在该如何改变它？

希望这会有所帮助，我通过这种方式解决了上述问题。@shkschneider 是对的。为了让你的代码工作导入android.support.v7.app.ActionBarDrawerToggle

mDrawerToggle = new ActionBarDrawerToggle(this,
                mDrawerLayout,
                R.string.drawer_open,
                R.string.drawer_close){

            @Override
            public void onDrawerClosed(View drawerView) {
                getSupportActionBar().setTitle(mTitle);
                invalidateOptionsMenu();
            }

            @Override
            public void onDrawerOpened(View drawerView) {
                getSupportActionBar().setTitle(mDrawerTitle);
                invalidateOptionsMenu();
            }
        };
