在res\layout目录下创建一个 activitylist.xml。内容如下：

这次我们不从AndroidManifest.xml中读取Activity列表，而是使用String Array资源。在res\value\string.xml 中添加下列Array资源：

          Bezier          Brush          Colors          Font    Image   Path   Pen   Shape    Transform                Bezier          Pattern ,Gradients          Colors          FontDemo, FontTypes    DrawMap, JumbleImage, SeeThroughImage   Polys, Paths   Lines, Dashes, LineCap,LineJoin   Oval ,Pear ,Shape2DDemo    Transform  

定义了这些资源后，可以在程序中使用自定义Adapter来显示列表：

class ActivityInfo{      int iconIndex;      String activityName;      String activityInfo;     }         class ActivityInfoAdapter extends ArrayAdapter{          int resource;      public ActivityInfoAdapter(Context context, int resourceId,        List objects) {       super(context, resourceId, objects);       resource=resourceId;      }          @Override      public View getView(int position,View ConvertView,ViewGroup parent){       LinearLayout activityInfoView;       ActivityInfo activityInfo=getItem(position);       String activity_Name=activityInfo.activityName;       String activity_Info=activityInfo.activityInfo;       int iconIndex=activityInfo.iconIndex;       if(ConvertView==null){        activityInfoView=new LinearLayout(getContext());        String inflater=Context.LAYOUT_INFLATER_SERVICE;        LayoutInflater vi;    vi=(LayoutInflater)getContext().getSystemService(inflater);        vi.inflate(resource, activityInfoView,true);       }else{        activityInfoView=(LinearLayout)ConvertView;       }       TextView activity_NameView     =(TextView)activityInfoView.findViewById(R.id.activityName);       TextView activity_InfoView      =(TextView)activityInfoView.findViewById(R.id.activityInfo);       ImageView iconView         =(ImageView)activityInfoView.findViewById(R.id.iconImage);       activity_NameView.setText(activity_Name);       activity_InfoView.setText(activity_Info);       iconView.setImageResource(iconIndex);       return activityInfoView;           }     }         public class AndroidGraphics2DTutorial extends ListActivity {          private ArrayList activityInfos          =new ArrayList();      private ActivityInfoAdapter aa;      private final static String packgeName="com.pstreets.graphics2d";        @Override      public void onCreate(Bundle savedInstanceState) {       super.onCreate(savedInstanceState);       Resources res = getResources();       String[] activity_Names = res.getStringArray(R.array.activity_name);       String[] activity_Infos = res.getStringArray(R.array.activity_info);       for(int i=0;i
类ActivityInfo定义列表每个元素的Data Model，为Activity的Icon资源ID，Activity Name以及Activity Info.
类ActivityInfoAdapter为自定义Adapter，关键的是public View getView(int  position,View ConvertView,ViewGroup  parent)。这个函数返回用来显示没个类别元素的View的示例。例子中为activitylist.xml 对应的Layout。
