我做了什么

Question

我不确定这是否重复，我尝试的可行补救措施并不起作用。（将在下面提到）

我目前正在使用Theme.AppCompat.NoActionBar进行我正在进行的项目，并且正在使用android.support.design.widget.AppBarLayout和android.support.design.widget.CollapsingToolbarLayout与android.support.v7.widget.Toolbar一起使用。

选项菜单旨在作为工具栏菜单的一部分，以便

如果用户需要更多信息，用户可以导航至关于活动
用户可以选择退出以结束会话。

以下是代码。那些用双星号表示的是我认为是onCreate()

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);
    }
}

按下任一项目时的Logcat输出。

11-01 04：13：06.317 31673-31673 / fyp.inrestaurant W / InputEventReceiver：   尝试完成输入事件但输入事件接收器已完成   已被处理。

11-01 04：13：12.517 31673-31673 / fyp.inrestaurant   W / InputEventReceiver：尝试完成输入事件但输入   事件接收者已被处理。

我做了什么

我实际上并没有完全理解答案所说的内容，因为答案只表明onCreateOptionsMenu会发生什么，onOptionsItemSelected()没有显示任何变化。所以，我唯一尝试的是将android:clickable = false放入toolbar_menu.xml文件的相应项目中。

Answer 1

解决

感谢@DeeV，问题在于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);将解决问题。

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);
                    }
                });
            }
        });
    }
