如何在表格布局中显示这个？我想显示一个像这样的 json 文件：
在我下面的代码中，网络连接正在工作，它解析图像名称和 url 并显示它。我只想知道如何在我的 json 文件中添加一些新属性，例如项目数量。
并访问我的 json 解析代码并以与此图像相同的布局显示。
这是我的 JSON 文件
{ "worldpopulation":
[
{
"rank":1,
"name": "Angelina",
"url": "http://www.bounty4u.com/android/images/angie.jpg"
},
{
"rank":2,
"name": "Ashton ",
"url": "http://www.bounty4u.com/android/images/ashton.jpg"
},
{
"rank":3,
"name": "Jackman",
"url": "http://www.bounty4u.com/android/images/hugh.jpg"
}
]
}
这是我的代码：
public class fifthscreen extends Activity {
HorizontalListView listview;
CategoryListAdapter3 cla;
String DescriptionAPI;
static ArrayList<Long> Category_ID = new ArrayList<Long>();
static ArrayList<String> Category_name = new ArrayList<String>();
static ArrayList<String> Category_image = new ArrayList<String>();
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fifthscreen);
listview = (HorizontalListView) this.findViewById(R.id.listview2);
cla = new CategoryListAdapter3(fifthscreen.this);
DescriptionAPI = Utils.DescriptionAPI;
// clearData();
try {
HttpClient client = new DefaultHttpClient();
HttpConnectionParams.setConnectionTimeout(client.getParams(), 15000);
HttpConnectionParams.setSoTimeout(client.getParams(),
15000);
HttpUriRequest request = new HttpGet(DescriptionAPI);
HttpResponse response = client.execute(request);
InputStream atomInputStream =
response.getEntity().getContent();
BufferedReader in = new BufferedReader(new
InputStreamReader(atomInputStream));
String line;
String str = "";
while ((line = in.readLine()) != null){
str += line;
}
JSONObject json = new JSONObject(str);
JSONArray data =
json.getJSONArray("worldpopulation");
for (int i = 0; i < data.length(); i++) {
JSONObject object = data.getJSONObject(i);
// JSONObject category =
object.getJSONObject("Category");
Category_ID.add(Long.parseLong(object.getString("rank")));
Category_name.add(object.getString("name"));
Category_image.add(object.getString("url"));
Log.d("Category name", Category_name.get(i));
listview.setAdapter(cla);
}
