adapter=new SimpleAdapter(this,getData(),R.layout.item,new String[]{"image","text"},new int[]{R.id.image1,R.id.text1});
gridView.setAdapter(adapter);
}
private List<Map<String,Object>> getData(){
for(int i=0;i<icon.length;i++){
Map<String,Object>map=new HashMap<String,Object>();
map.put("image1",icon[i]);
map.put("text1",iconName[i]);
