v7包中抽屉设置导航图标

android.support.v7.app.ActionBarDrawerToggle

        mDrawerToggle.setDrawerIndicatorEnabled(false); //disable "hamburger to arrow" drawable
        mDrawerToggle.setHomeAsUpIndicator(R.drawable.ic_drawer); //set your own
        // Finally we set the drawer toggle sync State
        mDrawerToggle.syncState();

设置完之后点击图标不能打开抽屉了。没有找到更好的办法
