Android：如何用字体很棒的图标（可用图标）替换导航抽屉图标

Question

I am working on an Android project in which I have a navigation drawer which shows a list of GroupSection objects. All the GroupSection objects contain a section icon. The drawer icons are determined by a TypedArray and some android specific syntax to get the resource. I want to replace that with a font-awesome icon. Each groupSection object has a getter groupSection.getSectionIcon(); which returns me the String of icon. I have added the icons in String.xml and have the fontawesome-webfont.ttf in assets directory.

I just cannot figure out how to replace the typed array with font-awesome icon. I tried findViewByID(R.id.awesome_icon).getId() , and some other possibilites. Thank you.

COde :

  public void set(List<RestSection> restSectionList, TypedArray navMenuIcons, Long groupId,
                    int canvasid, int sectionId) {
// Below are default icons
  navMenuIcons = getResources()
                .obtainTypedArray(R.array.nav_drawer_icons);
  for (RestSection restSection : restSectionList) {

// As you can see I am accessing the icons with there resource id. 
            navDrawerItems.add(new DrawerModel(restSection.getMsectionname(),
                    navMenuIcons.getResourceId(0, -1), restSection.getMsectionid()));
        }

Sample of string.xml :

 <string name="pinterest">&#xf0d2;</string>
    <string name="pinterest_square">&#xf0d3;</string>
    <string name="google_plus_square">&#xf0d4;</string>
    <string name="google_plus">&#xf0d5;</string>
    <string name="money">&#xf0d6;</string>
    <string name="caret_down">&#xf0d7;</string>
    <string name="caret_up">&#xf0d8;</string>
    <string name="caret_left">&#xf0d9;</string>
    <string name="caret_right">&#xf0da;</string>
    <string name="columns">&#xf0db;</string>

As in the for-loop I can directly get the icon String with getter, but setting it is where the issue lies. Any help would be nice. Thank you. :-)

Update

I tried the below code where I would manually set, but I get error for that as well :

Unable to find resource: 2131165836

Code :

for (RestSection restSection : restSectionList) {
            if (restSection.getSectionIcon() != null) {
                DrawerModel drawerModel = new DrawerModel();
                drawerModel.setTitle(restSection.getMsectionname());
                drawerModel.setId(restSection.getMsectionid());
                drawerModel.setIcon(R.string.try_icon);

                navDrawerItems.add(drawerModel);
            } else {
                navDrawerItems.add(new DrawerModel(restSection.getMsectionname(),
                        navMenuIcons.getResourceId(0, -1), restSection.getMsectionid()));
            }
        }

Font awesome is text. So if you want use them as icons u need to convert them to drawable.

You can use this TextDrawable example: https://stackoverflow.com/a/8831182/3206226
