        setContentView(R.layout.activity_attendance);

        mTitle=(String)getTitle();
        mDrawerLayout=(DrawerLayout)findViewById(R.id.drawer_layout);
        mDrawerList=(ListView)findViewById(R.id.drawer_list);
        information=getResources().getStringArray(R.array.Information);
        mDrawerList.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, information));
        mDrawerList.setOnItemClickListener(new OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> parent, View view,
                    int position, long id) {
                //Updated Attdce.this instead of Attendace.this
                Toast.makeText(Attdce.this, information [position]+ " was selected", Toast.LENGTH_LONG).show();
                    selectItem(position);

任何人都可以建议我..这是什么问题???我没有收到任何错误导航抽屉可以正确显示，但是当我在导航抽屉项上选择时，因此没有其他任何活动处于打开状态.

Can anyone please suggest me.. What is the problem??? I didn't get any error Navigation drawer is shown properly but when I select on navigation Drawer item so no any other activity is open..
