private List<Map<String, Object>> list=new ArrayList<Map<String,Object>>();
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.si);
ListView lv=(ListView)findViewById(R.id.lv);
String [] data=getResources().getStringArray(R.array.city);
for (int i = 0; i < data.length; i++) {
Map<String, Object> map=new HashMap<String, Object>();
map.put("photoId", R.drawable.ss);
map.put("data", data[i]);
list.add(map);
}
SimpleAdapter adapter=
new SimpleAdapter(this, list, R.layout.simple,
new String[]{"photoId","data"}, new int[]{R.id.lv,R.id.TextView01});
lv.setAdapter(adapter);
}
}
