安卓中GridView填充简单的文字和图片，笔记！

mGrid = (GridView) findViewById(R.id.mainGrid);
data_list = new ArrayList<Map<String, Object>>();
data_list=getData();
//创建适配器
String [] from ={"image","text"};
int [] to = {R.id.image,R.id.title};//grid_item布局中的两个控件id

simple_adapter = new SimpleAdapter(this, data_list, R.layout.grid_item, from, to);
mGrid .setAdapter(simple_adapter);

public List<Map<String, Object>> getData(){    
    for(int i=0;i<8;i++){
        Map<String, Object> map = new HashMap<String, Object>();
   map.put("image", new int[]{R.drawable.revoke, R.drawable.returngoods,      R.drawable.transaction_record, R.drawable.pre_authorization, R.drawable.offline, R.drawable.print, R.drawable.manage, R.drawable.balances }[i]);
        map.put("text", new String[]{getString(R.string.menu_revoke), getString(R.string.menu_return), getString(R.string.menu_transaction_record), getString(R.string.menu_preAuth)
                ,getString(R.string.menu_offline), getString(R.string.menu_print), getString(R.string.menu_manage), getString(R.string.menu_query_balance)}[i]);
        data_list.add(map);
    }
    return data_list;
}
