Android OnItemClickListener没有触发

我最近完成了一个项目，使用活动和一个工作得很好的导航抽屉。我决定建立一个更强大的项目，我会用碎片代替新的活动。当然，我的代码几乎完全相同，但是当选择导航抽屉中的项目时，我无法触发onClick。任何帮助将是美好的。我很担心drawerNavListView（左侧导航栏抽屉）Android OnItemClickListener没有触发

MainTemplate延伸活动

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

    // drawer creation 
    mDrawer = (DrawerLayout) findViewById(R.id.drawer_layout); 
    drawerListView = (ListView) findViewById(R.id.right_drawer); 
    drawerNavListView = (ListView) findViewById(R.id.left_drawer); 

    drawerItems = new ArrayList<NavDrawerItem>(); 
    navItem = new ArrayList<NavMenuItem>(); 

    navItem.add(new NavMenuItem("1", false, null)); 
    navItem.add(new NavMenuItem("2", true, "0")); 
    navItem.add(new NavMenuItem("3", false, null)); 
    navItem.add(new NavMenuItem("4", false, null)); 
    navItem.add(new NavMenuItem("5", false, null)); 
    navItem.add(new NavMenuItem("6", false, null)); 
    navItem.add(new NavMenuItem("7", false, null)); 

    menuAdapter = new NavMenuAdapter(getApplicationContext(), navItem); 
    drawerNavListView.setAdapter(menuAdapter); 

    // create the blank fragment 
    FragmentManager fm = getFragmentManager(); 
    FragmentTransaction ft = fm.beginTransaction(); 
    MainPageFrag mFrag = new MainPageFrag(); 
    ft.add(R.id.fragment_space, mFrag); 
    ft.commit(); 

    // JSON get class creation for notifications 
    new myNotificationTask().execute(); // call class at bottom 

    ... 

    // listener for clicking of a notification drawer item 
    drawerListView.setOnItemClickListener(new SlideOptionsClickListener()); 

    // listener for selecting a navigation drawer item 
    drawerNavListView.setOnItemClickListener(new SlideNavClickListener()); 

    // getting screen size 
    Display display = getWindowManager().getDefaultDisplay(); 
    screenSize = new Point(); 
    display.getSize(screenSize); 
    // setting pixels per minute for device 
    ppm = (screenSize.x * 4)/(25 * 60); 

    // create handler to call the notification update every 30 seconds 
    final Handler mHandler = new Handler(); 

    ... 
}

...（同一类）

private class SlideNavClickListener implements ListView.OnItemClickListener { 
    // this is where we inflate the fragment to the screen depending on the 
    // selection 
    FragmentManager fm = getFragmentManager(); 
    FragmentTransaction ft = fm.beginTransaction(); 

    @Override 
    public void onItemClick(AdapterView<?> parent, View view, int position, 
      long id) { 
     FragmentTransaction ft = getFragmentManager().beginTransaction(); 

     switch (position) { 
     case 0: 

      ScheduleViewFrag sFrag = new ScheduleViewFrag(); 
      ft.replace(R.id.fragment_space, sFrag); 
      ft.addToBackStack(null); 
      ft.commit(); 
      break; 
     case 1: 
      DelayFrag dFrag = new DelayFrag(); 

      Bundle bundle = new Bundle(); 
      bundle.putString(NOTIF_ID, drawerItems.get(position).getId()); 
      dFrag.setArguments(bundle); 

      ft.replace(R.id.fragment_space, dFrag); 
      ft.addToBackStack(null); 
      ft.commit(); 
      break; 
     default: // add more fragments once implemented here 
       break; 

     } 

     drawerNavListView.setSelection(position); 
     mDrawer.closeDrawer(drawerNavListView); 

    } 
}

你有在ListView的行中的按钮吗？ – Blackbelt

抽屉中的项目是一个线性布局基础，包含图像和文字浏览 – Elliott

假设LinearLayout是您的项目行的根目录，请向其添加android：descendantFocusability =“blocksDescendants”并重试一次 – Blackbelt

原来整个问题是我的XML文件中为主要布局。显然，使用包含主屏幕片段的线性布局在导航抽屉的两个列表视图上激活了onclick监听器。我原本是在两个以下，并由于某种原因，这导致了我的问题。希望这有助于未来的人。
