dialog_pencil.requestWindowFeature(Window.FEATURE_NO_TITLE);

는 android:windowFrame 와 같은 설정으로 대화상자 테두리를 제거한다

Dialog dialog = new Dialog(this,R.style.noBorderDialog)

를 자바코드 원하는 곳에 놓으면 대화상자를 소환할 수 있다.

Change Menu dynamically[All Fum]

메뉴 내용을 변경하는 코드[올 펌]

public class YourActivity extends Activity {

    private Menu menu;
    private String inBedMenuTitle = "Set to 'In bed'";
    private String outOfBedMenuTitle = "Set to 'Out of bed'";
    private boolean inBed = false;

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        super.onCreateOptionsMenu(menu);

        // Create your menu...

        this.menu = menu;
        return true;
    }

    private void updateMenuTitles() {
        MenuItem bedMenuItem = menu.findItem(R.id.bedSwitch);
        if (inBed) {
            bedMenuItem.setTitle(outOfBedMenuTitle);
        } else {
            bedMenuItem.setTitle(inBedMenuTitle);
        }
    }

}

아래 코드는 실시간과는 거리가 있다. 참고 정도로!

"Set to 'Out of Bed'"
public void setOptionsTitle(String status)
{
    bedStatus = status;

}
@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        super.onCreateOptionsMenu(menu);

        menu.add(bedStatus);


        // Return true so that the menu gets displayed.
        return true;
    }

실행 중 변경하는 또다른 법

menu.Clear ();
   if (TabActual == TabSelec.Anuncio)
   {
       menu.Add(10, 11, 0, "Crear anuncio");
       menu.Add(10, 12, 1, "Modificar anuncio");
       menu.Add(10, 13, 2, "Eliminar anuncio");
       menu.Add(10, 14, 3, "Actualizar");
   }
   if (TabActual == TabSelec.Fotos)
   {
       menu.Add(20, 21, 0, "Subir foto");
       menu.Add(20, 22, 1, "Actualizar");
   }
   if (TabActual == TabSelec.Comentarios)
   {
       menu.Add(30, 31, 0, "Actualizar");
   }

다이나믹하게 실행 후에 메뉴 내용 변경

@Override
public boolean onPrepareOptionsMenu(Menu menu) {
    menu.clear();

    if(isChangedStat) {
        menu.add(0, MENUITEM, 0, "True");
    } else {
        menu.add(0, MENUITEM, 0, "False");
    }
    return super.onPrepareOptionsMenu(menu);
}

카메라와 플레시를 다루는 기본 구조를 만들었다.

같은 자리에서 근 1주일여 이상 머무르는 중이다.

바닥으로 내려가서 점검하며 올라가려는 생각에 만들었다.

이것으로 실마리를 찾아가는 단초가 되었으면한다.
