ActionBarDrawerToggle animation

Question

I'm using the ActionBarDrawerToggle from the v7 appcompat library in my app and have some troubles with the menu-to-arrow animation. According to the material design guidelines the navigation drawer should overlap the toolbar and the icon animation should not be used when opening the drawer as I understand.

Why is the animation enabled by default when opening/closing the navigation drawer and how can I disable it?

Also, how can I trigger the animation on other occurences? I found this solution but it only works for Android API 11+ and its overwritten by calling setDrawerIndicatorEnabled(false) or by an expanded ActionView in the toolbar.

Answer 1

When you create your ActionBarDrawerToggle, do it like this to disable the animation/arrow and always show a hamburger:

drawerToggle = new ActionBarDrawerToggle(this, drawerLayout,
            getToolbar(), R.string.open, R.string.close) {

        @Override
        public void onDrawerClosed(View view) {
            super.onDrawerClosed(view);
        }

        @Override
        public void onDrawerOpened(View drawerView) {
            super.onDrawerOpened(drawerView);
            super.onDrawerSlide(drawerView, 0); // this disables the arrow @ completed state
        }

        @Override
        public void onDrawerSlide(View drawerView, float slideOffset) {
            super.onDrawerSlide(drawerView, 0); // this disables the animation 
        }
    };

Answer 2

I came across this problem tooday and found simple and (I belive) a proper solution:

Just don't set ActionBarDrawerToggle instance as DrawerListener for your DrawerLayout. This way ActionBarDrawerToggle will not perform animation that depends on drawer slide offset.

If you need a listener for DrawerLayout use DrawerLayout.DrawerListener.

edit: You can also set ActionBarDrawerToggle as a listener, but than you must overide its onDrawerSlide method. e.g. like this:

 mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.string.drawer_open_desc, R.string.drawer_close_desc) {
        @Override
        public void onDrawerSlide(View drawerView, float slideOffset) {
            super.onDrawerSlide(drawerView, 0);
        }
    };

calling super.onDrawerSlide() with 0 value instead of slideOffset, disables the animation
