Answer 2

自己琢磨出来了。现在取数据跟飞一样。
JSONArray jsonArray = new JSONArray(result);
for (int i = 0; i < jsonArray.length() - 1; i++) {
JSONObject js = jsonArray.getJSONObject(i);
String json = js.getString("subitem");
JSONObject jsonObject = new JSONObject(json);
name = jsonObject.getString("name");
subitemid = jsonObject.getString("subitemid");
Log.v("zyz", name + "-------");
Log.v("zyz", subitemid + "-------");
Picture picture = new Picture(name, images[i]);
list.add(picture);
}
adapter = new GridViewAdapter(IndexTow.this, list);
gridView.setAdapter(adapter);
adapter.notifyDataSetChanged();
