Question

我有一个OnItemClickListener并不想解雇：

我有一项活动，其中ViewPager设置了adapter和TabLayout，以便制作滑动标签。这是：

public class HierarchieActivity extends AppCompatActivity{
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_hierarchie);

        ViewPager viewPager = (ViewPager) findViewById(R.id.viewpager);
        SampleFragmentPagerAdapter pagerAdapter = new SampleFragmentPagerAdapter(getSupportFragmentManager(), HierarchieActivity.this);
        viewPager.setAdapter(pagerAdapter);

        TabLayout tabLayout = (TabLayout) findViewById(R.id.sliding_tabs);
        tabLayout.setupWithViewPager(viewPager);

        Toolbar toolbar = (Toolbar)findViewById(R.id.my_toolbar);
        setSupportActionBar(toolbar);
    }
}

在适配器（SampleFragmentPagerAdapter）中，我有两个fragments，其中包含包含TextViews和ListViews的LinearLayouts。这是一个片段及其布局：

public class PageFragmentHierarchie extends android.support.v4.app.Fragment {

    public static FileDAO dao = null;
    public static int etageMax = 1;
    public static int etageCourant = 1;
    public ListView listDossier;
    public ListView listDeck;

    public static PageFragmentHierarchie newInstance(int page) {
        Bundle args = new Bundle();
        PageFragmentHierarchie fragment = new PageFragmentHierarchie();
        return fragment;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_page_hierarchie, container, false);

        listDossier = (ListView)view.findViewById(R.id.listDossier);
        listDeck = (ListView)view.findViewById(R.id.listDeck);

        dao = new FileDAO(getContext());
        final SQLiteDatabase mDb = dao.open();

        // Here I'm making the adapter from a database
        Cursor cursorDossier = mDb.rawQuery("SELECT " + KEY + ", " + DOSSIER + " FROM " + TABLE_NAME + " WHERE " + DOSSIER +" IS NOT NULL AND " + ETAGE + "= ?;", new String[]{"1"});
        Cursor cursorDeck = mDb.rawQuery("SELECT " + KEY + ", " + DECK + " FROM " + TABLE_NAME + " WHERE " + DECK+" IS NOT NULL AND " + ETAGE + "= ?;", new String[]{"1"});

        SimpleCursorAdapter adapterDossier = new SimpleCursorAdapter(getContext(), R.layout.layout_dossiers, cursorDossier, new String[]{DOSSIER}, new int[]{R.id.text_dossier});
        SimpleCursorAdapter adapterDeck = new SimpleCursorAdapter(getContext(), R.layout.layout_decks, cursorDeck, new String[]{DECK}, new int[]{R.id.text_deck},0);

        listDossier.setAdapter(adapterDossier);
        listDeck.setAdapter(adapterDeck);

        listDossier.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
                Log.v(null,"CA MARCHE");
                // The problem cant be in the following part, I tried to put it as notes
                /*TextView textView = (TextView)view.findViewById(R.id.text_dossier);
                String text = textView.getText().toString();
                Cursor c = mDb.query(TABLE_NAME, new String[]{ETAGE}, "WHERE " + DOSSIER + "= ?", new String[]{text}, null,null,null);
                etageCourant = c.getInt(0);

                Cursor cursorDossier = mDb.rawQuery("SELECT " + KEY + ", " + DOSSIER + " FROM " + TABLE_NAME + " WHERE " + DOSSIER +" IS NOT NULL AND " + ETAGE + "= ?;", new String[]{String.valueOf(etageCourant)});
                Cursor cursorDeck = mDb.rawQuery("SELECT " + KEY + ", " + DECK + " FROM " + TABLE_NAME + " WHERE " + DECK +" IS NOT NULL AND " + ETAGE + "= ?;", new String[]{String.valueOf(etageCourant)});
                afficherHierarchie(cursorDossier, cursorDeck, listDossier, listDeck);
                getActivity().finish();
                startActivity(getActivity().getIntent());*/
            }
        });

        return view;
    }

    public void afficherHierarchie(Cursor cursorDossier, Cursor cursorDeck, ListView listDossier, ListView listDeck){
        SimpleCursorAdapter adapterDossier = new SimpleCursorAdapter(getContext(), R.layout.layout_dossiers, cursorDossier, new String[]{DOSSIER}, new int[]{R.id.text_dossier},0);
        SimpleCursorAdapter adapterDeck = new SimpleCursorAdapter(getContext(), R.layout.layout_decks, cursorDeck, new String[]{DECK}, new int[]{R.id.text_deck},0);

        listDossier.setAdapter(adapterDossier);
        listDeck.setAdapter(adapterDeck);
    }
}

这是布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/background"
android:id="@+id/FragmentHierarchie">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal">

        <TextView android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Dossiers :" />

        <TextView android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="aléatoire :"
            android:layout_marginLeft="270dp"/>

    </LinearLayout>

    <ListView
        android:layout_width="match_parent"
        android:layout_height="270dp"
        android:id="@+id/listDossier"/>

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Decks :" />

    <ListView
        android:layout_width="match_parent"
        android:layout_height="270dp"
        android:id="@+id/listDeck" />

</LinearLayout>

我的问题是：我尝试在其中一个OnItemClickListener上设置ListView，我在OnCreateView的{{1}}方法中设置了fragment（我认为是通常已经完成但是然后监听器根本不起作用：当我点击列表的项目时没有任何反应（尝试使用Log.v）

如果你花些时间帮助我，我会非常感谢。

OnItemClickListener无法正常工作
