Android, 옵션 메뉴 생성 방법

Android, 옵션 메뉴 생성 방법

---

여기에서 옵션 메뉴를 만들려고했는데 화면에 메뉴가 나오지 않아서 제가 잘못한 부분을 안내 해주세요 ...

MenuTest.java

public class MenuTest extends Activity {
   @Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater=getMenuInflater();
    inflater.inflate(R.menu.more_tab_menu, menu);
    return super.onCreateOptionsMenu(menu);

}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch(item.getItemId())
    {
    case R.id.feeds:
        break;
    case R.id.friends:
        break;
    case R.id.about:
        break;
    }
    return true;
}
}

그리고 내 XML 파일은 more_tab_menu.xml입니다.

<?xml version="1.0" encoding="utf-8"?>
<menu
xmlns:android="http://schemas.android.com/apk/res/android">
<item
    android:id="@+id/feeds"
    android:title="Feeds"/>
<item
    android:id="@+id/friends"
    android:title="Friends"/>
<item
    android:id="@+id/about"
    android:title="About"/>
</menu>

나를 안내 해주세요.

public class MenuTest extends Activity {

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.more_tab_menu, menu);

        // return true so that the menu pop up is opened
        return true; 
    }
}

에뮬레이터 또는 장치에서 메뉴 버튼 또는 아이콘을 누르는 것을 잊지 마십시오.

참조하십시오 : ==

private int group1Id = 1;

int homeId = Menu.FIRST;
int profileId = Menu.FIRST +1;
int searchId = Menu.FIRST +2;
int dealsId = Menu.FIRST +3;
int helpId = Menu.FIRST +4;
int contactusId = Menu.FIRST +5;

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    menu.add(group1Id, homeId, homeId, "").setIcon(R.drawable.home_menu);
    menu.add(group1Id, profileId, profileId, "").setIcon(R.drawable.profile_menu);
    menu.add(group1Id, searchId, searchId, "").setIcon(R.drawable.search_menu);
    menu.add(group1Id, dealsId, dealsId, "").setIcon(R.drawable.deals_menu);
    menu.add(group1Id, helpId, helpId, "").setIcon(R.drawable.help_menu);
    menu.add(group1Id, contactusId, contactusId, "").setIcon(R.drawable.contactus_menu);

    return super.onCreateOptionsMenu(menu); 
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
    case 1:
        // write your code here
        Toast msg = Toast.makeText(MainHomeScreen.this, "Menu 1", Toast.LENGTH_LONG);
        msg.show();
        return true;

    case 2:
        // write your code here
        return true;

    case 3:
        // write your code here
        return true;

    case 4:
        // write your code here
        return true;

    case 5:
        // write your code here
        return true;

    case 6:
        // write your code here
        return true;

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

onCreateOptionsMenu반환 방법을 변경하십시오 true. 문서 를 인용하려면 :

메뉴를 표시하려면 true를 반환해야합니다. false를 반환하면 표시되지 않습니다.

---

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    new MenuInflater(this).inflate(R.menu.folderview_options, menu);
    return (super.onCreateOptionsMenu(menu));
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {

    if (item.getItemId() == R.id.locationListRefreshLocations) {
        Cursor temp = helper.getEmployee(active_employeeId);
        String[] matches = new String[1];
        if (temp.moveToFirst()) {
            matches[0] = helper.getEmployerID(temp);
        }
        temp.close();               
        startRosterReceiveBackgroundTask(matches);
    } else if (item.getItemId()==R.id.locationListPrefs) {
        startActivity(new Intent(this, PreferencesUnlockScreen.class));
        return true;
    }           
    return super.onOptionsItemSelected(item);
}

대체 return super.onCreateOptionsMenu (menu); 와 TRUE를 반환; onCreateOptionsMenu 메소드 에서 도움이 될 것입니다.

활동에 onCreate 메소드 도 있어야합니다.

        else {
            message = "Why would you select that!?";
        }

        // show message via toast
        Toast toast = Toast.makeText(this, message, Toast.LENGTH_LONG);
        toast.show();

        return true;
    }

The previous answers have covered the traditional menu used in android. Their is another option you can use if you are looking for an alternative

https://github.com/AnshulBansal/Android-Pulley-Menu

Pulley menu is an alternate to the traditional Menu which allows user to select any option for an activity intuitively. The menu is revealed by dragging the screen downwards and in that gesture user can also select any of the options.

Android UI programming is a little bit tricky. To enable the Options menu, in addition to the code you wrote, we also need to call setHasOptionsMenu(true) in your overriden method OnCreate(). Hope this will help you out.

IF your Device is running Android v.4.1.2 or before,
the menu is not displayed in the action-bar.
But it can be accessed through the Menu-(hardware)-Button.

Good Day I was checked And if You choose Empty Activity You Don't have build in Menu functions For Build in You must choose Basic Activity In this way You Activity will run onCreateOptionsMenu

Or if You work in Empty Activity from start Chenge in styles.xml the

you can create options menu like below:

Menu XML code:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">

    <item
        android:id="@+id/Menu_AboutUs"
        android:icon="@drawable/ic_about_us_over_black"
        android:title="About US"/>
    <item
        android:id="@+id/Menu_LogOutMenu"
        android:icon="@drawable/ic_arrow_forward_black"
        android:title="Logout"/>
</menu>

How you can get the menu from MENU XML(Convert menu XML to java):

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

How to get Selected Item from Menu:

@Override
    public boolean onOptionsItemSelected(@NonNull MenuItem item) {
        switch (item.getItemId()){

            case R.id.Menu_AboutUs:
                //About US
                break;

            case R.id.Menu_LogOutMenu:
                //Do Logout
                break;
        }
        return super.onOptionsItemSelected(item);
    }
