Android ActionBar MenuItem LowerCase

Question

I want to make MenuItem title in the ActionBar to LowerCase.

my menu.xml

Answer 1

From source code in android.support.v7.internal.view.menu.ListMenuItemView

//Set text appearance in constructor from style
...
mTextAppearance = a.getResourceId(R.styleable.MenuView_android_itemTextAppearance, -1);
...

//Apply text appearance to view item
mTitleView = (TextView) findViewById(R.id.title);
if (mTextAppearance != -1) {
    mTitleView.setTextAppearance(mTextAppearanceContext, mTextAppearance);
}

In project: Create popup theme and apply it on popup creation for some custom popup if it's planned to use this appearance across whole application then put it to main application theme.

...
Context context = new ContextThemeWrapper(getActivity(), R.style.PopupTheme);
MenuPopupHelper optionsMenu = new MenuPopupHelper(context, menuBuilder, anchorView);
