mDrawerList.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v,
                int position, long id) {
switch (position) {
   case 1:
         Intent intent= new Intent(CurrentActivity.this,AnotherActivity.class);

Im using

public boolean onNavigationItemSelected(MenuItem item) {
        // Handle navigation view item clicks here.
        int id = item.getItemId();

        if (id == R.id.nav_cinema) {
                Intent cinemaIntent = new Intent(this, CinemaActivity.class);
                startActivity(cinemaIntent);
        } else if (id == R.id.nav_tv) {

        } else if (id == R.id.nav_tvseason) {

        } else if (id == R.id.nav_share) {

        } else if (id == R.id.nav_send) {

        }

    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
    drawer.closeDrawer(GravityCompat.START);
    return true;
}

and it's work for me :) (It's the default android nav drawer menu)

    if (id == R.id.activity_about) {
        Intent activity_about = new Intent(this, AboutActivity.class);
        startActivity(activity_about);
    } else if (id == R.id.nav_gallery) {

    } else if (id == R.id.nav_slideshow) {

    } else if (id == R.id.nav_manage) {

    } else if (id == R.id.nav_share) {

    } else if (id == R.id.nav_send) {

    }

    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
    drawer.closeDrawer(GravityCompat.START);
    return true;
}

}

as new implementation you can use the fresh Design Support Library that introduced the NavigationView class and DrawerLayout pattern. Check the release notes for more info.

if (id == R.id.activity_about) {
    Intent activity_about = new Intent(this, AboutActivity.class);
    startActivity(activity_about);
