프래그먼트 내의 onCreateOptionsMenu

프래그먼트 내의 onCreateOptionsMenu

---

setHasOptionsMenu(true)안에 넣었 onCreateView지만 여전히 onCreateOptionsMenu조각 내부를 호출 할 수 없습니다 .

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
                         Bundle savedInstanceState) {   
   setHasOptionsMenu(true);             
   return inflater.inflate(R.layout.facesheet, container, false);
}

아래는 내 onCreateOptionsMenu코드입니다.

@Override
public boolean onCreateOptionsMenu(com.actionbarsherlock.view.Menu menu) {
    getSupportMenuInflater().inflate(R.menu.layout, menu);
    return (super.onCreateOptionsMenu(menu));
}

내가 얻는 오류 메시지 :

방법 onCreateOptionsMenu(Menu)유형 조각은 무시하거나 슈퍼 방법을 구현해야합니다.

이 시도,

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    inflater.inflate(R.menu.menu_sample, menu);
    super.onCreateOptionsMenu(menu,inflater);
}

그리고이 onCreate줄을 추가하여 옵션이Toolbar

setHasOptionsMenu(true);

귀하의 이미 자동 생성 한 파일 고해상도 / 메뉴 / menu.xml 정의 action_settings을 .

당신에 MainActivity.java 다음과 같은 방법이있다 :

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

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    int id = item.getItemId();
    switch (id) {
        case R.id.action_settings:
            // do stuff, like showing settings fragment
            return true;
    }

    return super.onOptionsItemSelected(item); // important line
}

에서 onCreateView()당신의 조각 호출 방법 :

setHasOptionsMenu(true); 

또한이 두 가지 방법을 추가하십시오 :

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    inflater.inflate(R.menu.fragment_menu, menu);
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    int id = item.getItemId();
    switch (id) {
        case R.id.action_1:
            // do stuff
            return true;

        case R.id.action_2:
            // do more stuff
            return true;
    }

    return false;
}

Finally, add the new file res/menu/fragment_menu.xml defining action_1 and action_2.

This way when your app displays the Fragment, its menu will contain 3 entries:

• action_1 from res/menu/fragment_menu.xml
• action_2 from res/menu/fragment_menu.xml
• action_settings from res/menu/menu.xml

I tried the @Alexander Farber and @Sino Raj answers. Both answers are nice, but I couldn't use the onCreateOptionsMenu inside my fragment, until I discover what was missing:

Add setSupportActionBar(toolbar) in my Activity, like this:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.id.activity_main);

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

I hope this answer can be helpful for someone with the same problem.

Call

setSupportActionBar(toolbar)

inside

onViewCreated(...) 

of Fragment

@Override
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
    Toolbar toolbar = (Toolbar) view.findViewById(R.id.toolbar);
    ((MainActivity)getActivity()).setSupportActionBar(toolbar);
    setHasOptionsMenu(true);
}

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

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    inflater.inflate(R.menu.menu_sample, menu);
    super.onCreateOptionsMenu(menu,inflater);
}
