안드로이드 Menu 객체 만들기

코딩을 하다보면 일반 레이아웃 객체는 쉽게 선언 할 수 있는데 안드로이드 툴바 메뉴객체는 어떻게 선언해야하지? 하면서 모

를 때가 있습니다. 이럴때는 이렇게 하시면 됩니다.

add_menu.xml

<?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/add_all_check"
        android:title="@string/choice_all"
        android:checkable="true"
        android:checked="false"
        android:orderInCategory="101"
        app:showAsAction="ifRoom"
        />

    <item
        android:id="@+id/add_check_num"
        android:title=""
        android:orderInCategory="102"
        app:showAsAction="ifRoom"
        />
</menu>

/**선택 개수 메뉴*/

@Override

    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.add_menu, menu);
    mAddAllCheckMenu = menu.findItem(R.id.add_all_check);
    mAddCheckNumMenu = menu.findItem(R.id.add_check_num);
    mAddCheckNumMenu.setTitle(String.format(getString(R.string.choice_check_num), 0));
    return true;
}

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();
        Intent intent = null;
        if (id == R.id.add_all_check) {
            if (!mAddAllCheckMenu.isChecked()) {
                mAddAllCheckMenu.setChecked(true);
                mAddAllCheckMenu.setTitle(getString(R.string.choice_all));

            } else {
