安卓 : onOptionsItemSelected() does not respond

Question

我不确定这是否重复，我尝试过的可能的补救措施无效。 (下面会提到)

我目前正在为我正在做的项目使用 Theme.AppCompat.NoActionBar 并且正在使用 android.support.design.widget.AppBarLayout 和 android.support.design.widget.CollapsingToolbarLayout 与 android.support.v7.widget.Toolbar 串联。

选项菜单旨在与工具栏菜单分开，以便

1. 如果用户需要更多信息，他们可以导航到“关于” Activity
2. 用户可以选择注销以结束他们的 session 。

以下是代码。那些用双星号表示的是我认为是 onCreate()

代码中的重要部分

1) VacancyList.java : onCreate()

public class VacancyList extends AppCompatActivity
{
    private final static ArrayList <String> ELEMENTS= new ArrayList<>(Arrays.asList("restaurantID", "restaurantName", "restaurantType", "ST_ASText(restaurantLoc)", "restaurantLot", "restaurantVacancy", "restaurantOwner", "restaurantContact","restaurantEmail"));
    private final static String TAG_RESULT = "result";

    private Toolbar toolBar;
    private RecyclerView recyclVw;
    private RestInfoAdapter adapter;
    private SwipeRefreshLayout refresh;

    private ArrayList<RestInfo> rInf_LIST;

    //Temporary
    private TextView txtVw;

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

        **toolBar = (Toolbar)findViewById(R.id.toolbar);
        toolBar.inflateMenu(R.menu.toolbar_menu);**

        rInf_LIST = new ArrayList<>();

        //AsyncTask calls
        new ListGetterTask(true).execute();

        //Setup Recycler View with the appropriate adapter and layout.
        recyclVw = (RecyclerView)findViewById(R.id.recyclerView);
        adapter = new RestInfoAdapter(this, rInf_LIST);
        GridLayoutManager glm = new GridLayoutManager(this, 1);

        recyclVw.setLayoutManager(glm);
        recyclVw.setAdapter(adapter);

        refresh = (SwipeRefreshLayout)findViewById(R.id.refresh);
        refresh.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
            @Override
            public void onRefresh() {
                new Handler().post(new Runnable() {
                    @Override
                    public void run() {
                        new ListGetterTask(false).execute();
                        Toast.makeText(VacancyList.this, "ListGetter Executed", Toast.LENGTH_SHORT).show();
                        refresh.setRefreshing(false);
                    }
                });
            }
        });
    }

2) VacancyList.java : onCreateOptionsMenu()

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

3) VacancyList.java : onOptionsItemSelected()

@Override
public boolean onOptionsItemSelected(MenuItem item)
{
    switch (item.getItemId())
    {
        case R.id.aboutPage:
        {
            startActivity(new Intent(VacancyList.this, About.class));
            return true;
        }
        case R.id.logOut:
        {
            String prefName = getString(R.string.prefName), key0 = getString(R.string.key0), key1 = getString(R.string.key1), key2 = getString(R.string.key2);

            SharedPreferences sharedPref = getSharedPreferences(prefName, Context.MODE_PRIVATE);
            SharedPreferences.Editor edtr = sharedPref.edit();

            edtr.putString(key0, "loggedOut");
            edtr.remove(key1);
            edtr.remove(key2);

            edtr.apply();
            startActivity(new Intent(VacancyList.this, MainActivity.class));

            return true;
        }
        default:
            return super.onOptionsItemSelected(item);
    }
}

        android:title="@string/logout"
        app:showAcAction="never"
        android:clickable="false"/>

按下其中一项时的 Logcat 输出。

11-01 04:13:06.317 31673-31673/fyp.inrestaurant W/InputEventReceiver: Attempted to finish an input event but the input event receiver has already been disposed.

11-01 04:13:12.517 31673-31673/fyp.inrestaurant W/InputEventReceiver: Attempted to finish an input event but the input event receiver has already been disposed.

我做了什么

我实际上不太明白答案在说什么，因为答案只表明 onCreateOptionsMenu 会发生什么，而 onOptionsItemSelected() 没有显示任何变化。因此，我唯一尝试过的就是将 android:clickable = false 中的相应项目放入 toolbar_menu.xml 文件中。

编辑 1:适配器和 RestInfo

1) RestInfo.java

Answer 1

已解决

感谢@DeeV，问题出在有工具栏但没有代码告诉应用程序该工具栏被用作操作栏的部分。

因此，添加setSupportActionBar(toolBar);即可解决问题。

更新了 onCreate()

的代码

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

        devOnly = (FloatingActionButton)findViewById(R.id.devOnly);
        devOnly.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                String prefName = getString(R.string.prefName), key0 = getString(R.string.key0), key1 = getString(R.string.key1), key2 = getString(R.string.key2);

                SharedPreferences sharedPref = getSharedPreferences(prefName, Context.MODE_PRIVATE);
                SharedPreferences.Editor edtr = sharedPref.edit();

                edtr.putString(key0, "loggedOut");
                edtr.remove(key1);
                edtr.remove(key2);

                edtr.apply();
                startActivity(new Intent(VacancyList.this, MainActivity.class));
            }
        });

        toolBar = (Toolbar)findViewById(R.id.toolbar);
        toolBar.inflateMenu(R.menu.toolbar_menu);
        setSupportActionBar(toolBar);

        rInf_LIST = new ArrayList<>();

        //AsyncTask calls
        new ListGetterTask(true).execute();

        //Setup Recycler View with the appropriate adapter and layout.
        recyclVw = (RecyclerView)findViewById(R.id.recyclerView);
        adapter = new RestInfoAdapter(this, rInf_LIST);
        GridLayoutManager glm = new GridLayoutManager(this, 1);

        recyclVw.setLayoutManager(glm);
        recyclVw.setAdapter(adapter);

        refresh = (SwipeRefreshLayout)findViewById(R.id.refresh);
        refresh.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
            @Override
            public void onRefresh() {
                new Handler().post(new Runnable() {
                    @Override
                    public void run() {
                        new ListGetterTask(false).execute();
                        Toast.makeText(VacancyList.this, "ListGetter Executed", Toast.LENGTH_SHORT).show();
                        refresh.setRefreshing(false);
                    }
                });
            }
        });
    }
