如何在单击上一个抽屉项目的特定片段时打开下一个抽屉

Question

在我的应用程序中，我想通过单击 android 中导航抽屉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 并且片段涉及 activity 。现在我想要的是，当我点击 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，我附上我的 mainActivity.java

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();

    }

这些是我用 6 个项目制作一个抽屉的代码，现在我希望当我点击任何项目时它必须打开那个特定片段的特定抽屉，我已经搜索但没有找到 google .它与 google 驱动器的应用程序相同。

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

这是Android使用导航抽屉滑动菜单的教程。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");
        }
    }
