کلیک در navigation drawer کار نمی کند.

سلام به دوستان

من در پروژم یک navigation drawer دارم که کلیک روی آیتم های آن کار نمی کند. دوستان کمک کنید. 

mainactivity:

   dataList = new ArrayList<DrawerItem>();
        mTitle = mDrawerTitle = getTitle();
        mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        mDrawerList = (ListView) findViewById(R.id.Right_drawer);
        mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.END);

        dataList.add(new DrawerItem("کل"));
        dataList.add(new DrawerItem("معین"));
        dataList.add(new DrawerItem("معین شناور"));
        dataList.add(new DrawerItem("تفصیلی"));
        dataList.add(new DrawerItem("تفصیلی شناور"));
        dataList.add(new DrawerItem("جزء"));
        dataList.add(new DrawerItem("جزء شناور"));
        dataList.add(new DrawerItem("ریز"));
        dataList.add(new DrawerItem("ریز شناور"));

        draweradapter = new CustomDrawerAdapter(this, R.layout.custom_drawer_item,dataList);
        mDrawerList.setClickable(true);
        mDrawerList.setAdapter(draweradapter);
        mDrawerToggle = new ActionBarDrawerToggle(this,mDrawerLayout,R.drawable.slideshow,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);
                //Toast.makeText(getApplicationContext(), "Clicked", Toast.LENGTH_LONG).show();
                mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
                getActionBar().setTitle(mTitle);

            }

            /** Called when a drawer has settled in a completely open state. */
            public void onDrawerOpened(View drawerView) {
                super.onDrawerOpened(drawerView);
               // Toast.makeText(getApplicationContext(), "Clicked", Toast.LENGTH_LONG).show();
                getActionBar().setTitle(mDrawerTitle);

            }
