3 Line Icon Is Not Animating Into A Smaller Image In Navigation Drawer

The small icon(indicator or 3 line) beside the logo, is not changing into a smaller one. --> this image is not animating, When I click the apps' logo the drawer is opened but

Solution 1:

please ensure you put this line into your code where you declared your ActionBarDrawerToggle:

mDrawerLayout.setDrawerListener(mDrawerToggle);

as you can see in this example:

publicclassMyActivityextendsActionBarActivity  {

    privateDrawerLayout mDrawerLayout;
    privateListView mDrawerList;
    privateActionBarDrawerToggle mDrawerToggle;
    privateString[] menuitems;

    @OverrideprotectedvoidonCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.activity_main);
        mDrawerLayout   = (DrawerLayout) findViewById(R.id.drawer_layout);
        mDrawerList     = (ListView) findViewById(R.id.left_drawer);
        menuitems   = getResources().getStringArray(R.array.optionsname);

        MyDrawerAdapter draweradapter = newMyDrawerAdapter(getApplicationContext(), menuitems);
        mDrawerList.setAdapter(draweradapter);

        mDrawerToggle = newActionBarDrawerToggle(this, mDrawerLayout, R.drawable.ic_navigation_drawer, R.string.drawer_open, R.string.drawer_close) {

            publicvoidonDrawerClosed(View view) {
                invalidateOptionsMenu();
            }

            publicvoidonDrawerOpened(View drawerView) {
                invalidateOptionsMenu();
            }

            @OverridepublicvoidonDrawerSlide(View drawerView, float slideOffset) {
                super.onDrawerSlide(drawerView, slideOffset);
                mDrawerLayout.bringToFront();
                mDrawerLayout.bringChildToFront(drawerView);
                mDrawerLayout.requestLayout();
                mDrawerLayout.invalidate();
            }
        };

        mDrawerLayout.setDrawerListener(mDrawerToggle);

        mDrawerList.setOnItemClickListener(newDrawerItemClickListener());
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        getSupportActionBar().setDisplayShowTitleEnabled(false);
        getSupportActionBar().setHomeButtonEnabled(true);
        getSupportActionBar().setIcon(newColorDrawable(0x00000000));
        getSupportActionBar().setBackgroundDrawable(newColorDrawable(0xffffffff));
    }
}

if you forget to add the drawerlistener to the drawerlayout it wont animate your drawer icon.

Solution 2:

Although I had this problem with SherlockNavigationDrawer, maybe it help someone: ensure you don't forgot to call super in overriden drawer's methods (onDrawerOpened/Closed).
