Android-带菜单图标而不是后退按钮的导航抽屉

Question

I'm starting learning android and when I created my app I chose the Navigation Drawer template and here is the problem:

1) Even though I'm at the homepage the back button is displayed, and it opens the menu

2) I'd like to have a menu icon in every single page and let the hardware back button handle the intent history

So basically I'd like to know how to change back button icon to menu icon.

code: (onCreateOptionsMenu)

ActionBar actionBar = getActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setHomeButtonEnabled(true);

I can show/hide the back button but I can't figure out where it's calling the icon itself

Sorry if it's a silly question but I didn't find good answers to this (on ly this link: https://developer.android.com/training/implementing-navigation/nav-drawer.html )

Here you will find a method where i do some customization over my actionBar try to use some of it :) , also you will need to make your own custom action bar xml file

    private void setCustomActionBar() {

    ActionBar mActionBar = this.getSupportActionBar();
    mActionBar.setDisplayShowHomeEnabled(false);
    mActionBar.setDisplayShowTitleEnabled(false);

    LayoutInflater mInflater = LayoutInflater.from(this);
    View mCustomView = mInflater.inflate(R.layout.custom_main_actionbar, null);

    mActionBar.setCustomView(mCustomView);
    mActionBar.setDisplayShowCustomEnabled(true);

    actionBarTitle = (TextView) mCustomView.findViewById(R.id.action_bar_title_tv);
    actionBarHomeBtn = (ImageView) mCustomView.findViewById(R.id.action_bar_app_icon);
    actionBarSyncBtn = (ImageView) mCustomView.findViewById(R.id.action_bar_sync_btn);
    actionBarSearchBtn = (ImageView) mCustomView.findViewById(R.id.action_bar_search_btn);
    actionBarHomeBtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            if (mDrawerLayout.isDrawerOpen(mDrawerList)) {
                mDrawerLayout.closeDrawer(mDrawerList);
            } else {
                mDrawerLayout.openDrawer(mDrawerList);
            }
        }
    });

    actionBarSyncBtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

        }
    });

    actionBarSearchBtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

        }
    });
}
