java - 如何通过单击上一个抽屉项目的特定 fragment 来打开下一个抽屉

Question

在我的应用程序中，我想通过单击 android 中抽屉导航的前一个抽屉中的导航栏项目来打开新抽屉。就像现在我有 mainactivity.java 和 fragment 涉及该 Activity 。现在我想要的是，当我单击 mainactivity.java 抽屉项目的任何项目时，它必须打开另一个项目中具有不同值的抽屉，我正在附加 mainActivity.java 的代码

public class MainActivity extends AppCompatActivity{
    DrawerLayout mDrawerLayout;
    NavigationView mNavigationView;
    FragmentManager mFragmentManager;
    FragmentTransaction mFragmentTransaction;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main_coordinator);

        /**
         *Setup the DrawerLayout and NavigationView
         */

             mDrawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout);
             mNavigationView = (NavigationView) findViewById(R.id.shitstuff) ;

        /**
         * Lets inflate the very first fragment
         * Here , we are inflating the TabFragment as the first Fragment
         */

             mFragmentManager = getSupportFragmentManager();
             mFragmentTransaction = mFragmentManager.beginTransaction();
             mFragmentTransaction.replace(R.id.containerView,new TabFragment()).commit();
        /**
         * Setup click events on the Navigation View Items.
         */

             mNavigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
             @Override
             public boolean onNavigationItemSelected(MenuItem menuItem) {
                mDrawerLayout.closeDrawers();



                 if (menuItem.getItemId() == R.id.nav_item_home) {
                     FragmentTransaction fragmentTransaction = mFragmentManager.beginTransaction();
                     fragmentTransaction.replace(R.id.containerView,new coordinatorPanelFragment()).commit();

                 }


                 if (menuItem.getItemId() == R.id.nav_item_fllclass) {
                    FragmentTransaction xfragmentTransaction = mFragmentManager.beginTransaction();
                    xfragmentTransaction.replace(R.id.containerView,new fillClassFragment()).commit();
                }
///

                 if (menuItem.getItemId() == R.id.nav_item_fillstudent) {
                     FragmentTransaction fragmentTransaction = mFragmentManager.beginTransaction();
                     fragmentTransaction.replace(R.id.containerView,new fillStudentFragment()).commit();

                 }


                 if (menuItem.getItemId() == R.id.nav_item_fillschedule) {
                    FragmentTransaction xfragmentTransaction = mFragmentManager.beginTransaction();
                    xfragmentTransaction.replace(R.id.containerView,new fillscheduleFragment()).commit();
                }


                 if (menuItem.getItemId() == R.id.nav_item_seebunk) {
                    FragmentTransaction xfragmentTransaction = mFragmentManager.beginTransaction();
                    xfragmentTransaction.replace(R.id.containerView,new seeBunkedStudentFragment()).commit();
                }

                 if (menuItem.getItemId() == R.id.nav_item_cus) {
                     FragmentTransaction xfragmentTransaction = mFragmentManager.beginTransaction();
                     xfragmentTransaction.replace(R.id.containerView,new ContactusFragment()).commit();
                 }

                 if (menuItem.getItemId() == R.id.nav_item_help) {
                     FragmentTransaction xfragmentTransaction = mFragmentManager.beginTransaction();
                     xfragmentTransaction.replace(R.id.containerView,new helpCoorFragment()).commit();
                 }





                 return false;
            }

        });

        /**
         * Setup Drawer Toggle of the Toolbar
         */

                android.support.v7.widget.Toolbar toolbar = (android.support.v7.widget.Toolbar) findViewById(R.id.toolbar);
                ActionBarDrawerToggle mDrawerToggle = new ActionBarDrawerToggle(this,mDrawerLayout, toolbar,R.string.app_name,
                R.string.app_name);

                mDrawerLayout.setDrawerListener(mDrawerToggle);

                mDrawerToggle.syncState();

    }

这些是我制作一个包含 6 个项目的抽屉的代码，现在我希望当我单击任何项​​目时，它必须打开该特定 fragment 的特定抽屉，我已经搜索过，但在谷歌上没有找到答案。它与谷歌驱动器的应用程序。

看看这些例子，我希望它们能帮助您解决问题。 http://www.androidhive.info/2013/11/android-sliding-menu-using-navigation-drawer/

这是Android滑动菜单使用抽屉导航的教程。所需的代码是我粘贴在这里:-

private class SlideMenuClickListener implements
            ListView.OnItemClickListener {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position,
                long id) {
            // display view for selected nav drawer item
            displayView(position);
        }
    }

     /**
     * Diplaying fragment view for selected nav drawer list item
     * */
    private void displayView(int position) {
        // update the main content by replacing fragments
        Fragment fragment = null;
        switch (position) {
        case 0:
            fragment = new HomeFragment();
            break;
        case 1:
            fragment = new FindPeopleFragment();
            break;
        case 2:
            fragment = new PhotosFragment();
            break;
        case 3:
            fragment = new CommunityFragment();
            break;
        case 4:
            fragment = new PagesFragment();
            break;
        case 5:
            fragment = new WhatsHotFragment();
            break;

        default:
            break;
        }

        if (fragment != null) {
            FragmentManager fragmentManager = getFragmentManager();
            fragmentManager.beginTransaction()
                    .replace(R.id.frame_container, fragment).commit();

            // update selected item and title, then close the drawer
            mDrawerList.setItemChecked(position, true);
            mDrawerList.setSelection(position);
            setTitle(navMenuTitles[position]);
            mDrawerLayout.closeDrawer(mDrawerList);
        } else {
            // error in creating fragment
            Log.e("MainActivity", "Error in creating fragment");
        }
    }
