Как использовать намерения в элементах recycliewiew навигационного ящика, чтобы открыть новый фрагмент действия?

Question

Мой activity класс как следующее:

/*ToolBar SetUp*/ 
    app_toolBar = (Toolbar) findViewById(R.id.toolbar_header); 
    setSupportActionBar(app_toolBar); 
    getSupportActionBar().setDisplayShowTitleEnabled(true); 
    getSupportActionBar().setDisplayHomeAsUpEnabled(true); 
    getSupportActionBar().setHomeButtonEnabled(true); 


    String TITLES[] = {"Home", "Search", "HalalRewards", "Contact Us", "User Guide", "F.A.Q", "Settings", "Share"}; 
    int ICONS[] = {R.drawable.ic_action_home, R.drawable.ic_search, R.drawable.ic_rewardsss, R.drawable.ic_contact, R.drawable.ic_uguide, R.drawable.ic_faq, R.drawable.ic_settings, R.drawable.ic_shareee}; 

    String NAME = "ESignature IT Solution"; 
    String EMAIL = "info@esignature.com.np"; 
    int PROFILE = R.drawable.intologo; 

    /*Drawer SetUp*/ 
    mRecyclerView = (RecyclerView) findViewById(R.id.RecyclerView); // Assigning the RecyclerView Object to the xml View 
    mRecyclerView.setHasFixedSize(true);       // Letting the system know that the list objects are of fixed size 


    mAdapter = new DrawerAdapter(TITLES, ICONS, NAME, EMAIL, PROFILE); 
    // Creating the Adapter of MyAdapter class(which we are going to see in a bit) 
    // And passing the titles,icons,header view name, header view email, 
    // and header view profile picture 

    mRecyclerView.setAdapter(mAdapter);        // Setting the adapter to RecyclerView 
    mRecyclerView.setOnClickListener(new DrawerItemClickListener()); 
    mLayoutManager = new LinearLayoutManager(this);     // Creating a layout Manager 

    mRecyclerView.setLayoutManager(mLayoutManager);     // Setting the layout Manager 


    Drawer = (DrawerLayout) findViewById(R.id.DrawerLayout);  // Drawer object Assigned to the view 
    mDrawerToggle = new ActionBarDrawerToggle(this, Drawer, app_toolBar, R.string.openDrawer, R.string.closeDrawer) { 

     @Override 
     public void onDrawerOpened(View drawerView) { 
      super.onDrawerOpened(drawerView); 
      // TO DO Execute code when Drawer view open 
     } 

     @Override 
     public void onDrawerClosed(View drawerView) { 
      super.onDrawerClosed(drawerView); 
      // TO DO Execute code when once Drawer is close 
     } 


    }; 
    Drawer.setDrawerListener(mDrawerToggle); // Drawer Listener set to the Drawer toggle 
    mDrawerToggle.syncState();    // Finally we set the drawer toggle sync State 

} 


@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    getMenuInflater().inflate(R.menu.menu_main, menu); 
    return true; 
} 

@Override 
public boolean onOptionsItemSelected(MenuItem item) { 

    switch (item.getItemId()) { 

     case R.id.action_settings: 
      return true; 

    } 

    return super.onOptionsItemSelected(item); 
} 

// create fragmrnt loader funtion 
// id get from adapter .... 


/* The click listner for ListView in the navigation drawer */ 
private class DrawerItemClickListener implements AdapterView.OnItemClickListener, View.OnClickListener { 
    @Override 
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) { 
     /*selectItem(position);*/ /////////// 
     // display view for selected nav drawer item 
     displayView(position); 

    } 


    @Override 
    public void onClick(View v) { 

    } 
} 

// 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 Fragment(); 
      break;*/ 
     case 1: 
      fragment = new SearchActivity(); 
      break; 
     case 2: 
      fragment = new HalalRewardsActivity(); 
      break; 
     case 3: 
      fragment = new ContactUsFragment(); 
      break; 
     case 4: 
      fragment = new GuideFragment(); 
      break; 
     case 5: 
      fragment = new FaqFragment(); 
      break; 
     case 6: 
      fragment = new SettingsFragment(); 
      break; 
     case 7: 
      fragment = new ShareFragment(); 
      break; 

     default: 
      break; 
    } 

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


     Drawer.closeDrawer(mRecyclerView); 
    } else { 
     // error in creating fragment 
     Log.e("MainActivity", "Error in creating fragment"); 
    } 
} 
} 

Я новый программист. Поэтому достойная похвала будет достойна похвалы. Спасибо заранее.

Дон "т пишут:.

mRecyclerView.setOnClickListener(new DrawerItemClickListener()); 

потому что OnClick не применяется в RecyclerView Вместо этого используйте следующие коды:

 final GestureDetector mGestureDetector = new GestureDetector(MainActivity.this, new GestureDetector.SimpleOnGestureListener() { 

     @Override 
     public boolean onSingleTapUp(MotionEvent e) { 
      return true; 
     } 

    }); 


    mRecyclerView.addOnItemTouchListener(new RecyclerView.OnItemTouchListener() { 
     @Override 
     public boolean onInterceptTouchEvent(RecyclerView recyclerView, MotionEvent motionEvent) { 
      View child = recyclerView.findChildViewUnder(motionEvent.getX(), motionEvent.getY()); 

      if (child != null && mGestureDetector.onTouchEvent(motionEvent)) { 
       Drawer.closeDrawers(); 

       Toast.makeText(MainActivity.this, "The Item Clicked is: " + recyclerView.getChildPosition(child), Toast.LENGTH_SHORT).show(); 

       if (recyclerView.getChildAdapterPosition(child) == 0) { 

       } else if (recyclerView.getChildAdapterPosition(child) == 5) { 

       } else { 
        LoadFragmentView(recyclerView.getChildPosition(child)); 
       } 
      } 

      return false; 
     } 

     @Override 
     public void onTouchEvent(RecyclerView recyclerView, MotionEvent motionEvent) { 

     } 
    });
