Question

I have an application using navigation drawer that provides list of locations. In the drawer, there are several options (like choosing country, city, etc) that user can setu

Answer 1

When you setup the ActionBarDrawerToggle you can "implement" the onDrawerClosed and onDrawerOpened callbacks. See the following example from the Docs:

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

        /** Called when a drawer has settled in a completely closed state. */
        public void onDrawerClosed(View view) {
            super.onDrawerClosed(view);
            // Do whatever you want here
        }

        /** Called when a drawer has settled in a completely open state. */
        public void onDrawerOpened(View drawerView) {
            super.onDrawerOpened(drawerView);
            // Do whatever you want here
        }
    };
// Set the drawer toggle as the DrawerListener
mDrawerLayout.addDrawerListener(mDrawerToggle);

Edit: Now the setDrawerListener is deprecated, use addDrawerListener instead.

Answer 2

setDrawerListener is deprecated use addDrawerListener instead.

drawerLayout.addDrawerListener(new DrawerListener() {
                @Override
                public void onDrawerSlide(View view, float v) {

                }

                @Override
                public void onDrawerOpened(View view) {

                }

                @Override
                public void onDrawerClosed(View view) {

                }

                @Override
                public void onDrawerStateChanged(int i) {

                }
            });

reVerse answer is right in case you are using ActionBar as well. in case you just use the DrawerLayout directly, you can add a DrawerListener to it:

View drawerView = findViewById(R.id.drawer_layout);
if (drawerView != null && drawerView instanceof DrawerLayout) {
    mDrawer = (DrawerLayout)drawerView;
    mDrawer.setDrawerListener(new DrawerListener() {
            @Override
            public void onDrawerSlide(View view, float v) {

            }

            @Override
            public void onDrawerOpened(View view) {

            }

            @Override
            public void onDrawerClosed(View view) {
                // your refresh code can be called from here
            }

            @Override
            public void onDrawerStateChanged(int i) {

            }
        });
}

As per kit's comment, addDrawerListener() should be used now that setDrawerListener() has been deprecated.
