如何将自定义字体应用于资源中的字符串

Question

我有资源<string-array name="channel_names"> 和ID

 <string-array name="channel_id">
    <item>UCWUi0SCvgAGNJyS3Jmfibow</item>
 </string-array>

或者不能将自定义字体用于字符串数组？ 在课堂上：

         @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_home);
      Typeface font = Typeface.createFromAsset(getResources().getAssets(), "fonts/Arvo-BoldItalic.ttf");
                    channelNames = getResources().getStringArray(R.array.channel_names);
                    I do not understand what to use? .setTypeface(channelNames,font);

I use navigation Drawer:
I do not have the xml file for the navigation drawer I draw to code
      @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_home);




        layoutList = (FrameLayout) findViewById(R.id.fragment_container);
        toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        decorView = getWindow().getDecorView();
        fragmentVideo = (FragmentVideo) getFragmentManager()
                .findFragmentById(R.id.video_fragment_container);

        Typeface font = Typeface.createFromAsset(getResources().getAssets(), "fonts/Arvo-BoldItalic.ttf");


        channelNames = getResources().getStringArray(R.array.channel_names);


         .setTypeface(channelNames,font);

        channelId = getResources().getStringArray(R.array.channel_id);
        videoTypes = getResources().getStringArray(R.array.video_types);
