Java Can'；t使用CustomAdapter启用上下文操作模式<；MyClass>；

我正试图使用从

ArrayAdapter

继承的自定义适配器在

ListView

中启用上下文操作模式。而且不能。只是长时间点击没有发生任何事情。既不在UI中，也不在日志中。
当我使用

ArrayAdapter

时，一切正常。我犯了什么错，请解释一下。提前谢谢

这是我的档案

MainActivity.java

public class MainActivity extends AppCompatActivity {

public static final String TAG = "LOG";

ListView listView;
ArrayAdapter<Note> adapter; // It doesn't work.
//ArrayAdapter<String> adapter; // It works.
List<Note> notes;
static final int REQUEST_CODE_NOTE = 1;
Button btnAdd;

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

    setContentView(R.layout.activity_main);

    listView = (ListView)findViewById(android.R.id.list);

    notes = new ArrayList<>();
    notes.add(new Note("First note"), new Note("Second note"));

    adapter = new NoteAdapter(this, notes);
    listView.setAdapter(adapter);

    listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE_MODAL);
    listView.setMultiChoiceModeListener(new AbsListView.MultiChoiceModeListener() {
        @Override
        public void onItemCheckedStateChanged(ActionMode actionMode, int i, long l, boolean b) {

        }

        @Override
        public boolean onCreateActionMode(ActionMode actionMode, Menu menu) {
            Log.d(MainActivity.TAG, "onCreateActionMode");
            MenuInflater inflater = actionMode.getMenuInflater();
            inflater.inflate(R.menu.context_menu, menu);
            Toast.makeText(MainActivity.this, "onCreateActionMode", Toast.LENGTH_SHORT).show();
            return true;
        }

        @Override
        public boolean onPrepareActionMode(ActionMode actionMode, Menu menu) {
            return false;
        }

        @Override
        public boolean onActionItemClicked(ActionMode actionMode, MenuItem menuItem) {
            actionMode.finish();
            return true;
        }

        @Override
        public void onDestroyActionMode(ActionMode actionMode) {

        }
    });

    //registerForContextMenu(listView);

    btnAdd = (Button) findViewById(R.id.add_button);
    btnAdd.setOnClickListener(this);
}
}

将代码减少到可验证的最小完整示例将大大有助于获得答案。你的代码墙太大了。如果我知道错误在哪里，我肯定会减少代码。通过删除代码并保留问题，你通常可以自己发现问题。如果你花点时间举一个简单的例子，你会让更多的人关注你的问题。谢谢你的建议。我明白这一点。我花了今天的时间来确定问题，但没有成功。所以我认为在这种情况下，所有这些代码都与搜索解决方案相关。
