    private String[] information;
    @Override

        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);
            }

        });
        drawerListener=new ActionBarDrawerToggle(this, mDrawerLayout, R.drawable.ic_menu_black_24dp,R.string.drawer_open, R.string.drawer_close)
        {
            @Override

                     startActivity(intent1);
                     break;

                 case 4:

                     startActivity(intent1);
                     break;

                 case 5:
                     intent1 = new Intent(Attdce.this, Help.class);
                     startActivity(intent1);
                     break;

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.
