我是想要把我从json解析得到的字符串数据 添加到listview里每一个item的textview里。现在遇到了点问题，求助大神。这个问题应该很基础的。。 主要问题是我得到的数据shuzhangyalist 在getdata方法里。。。 谢谢各位了
上代码
public class ShuzhangyaGraph extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.graph_of_shuzhangya);
ListView listview = (ListView) findViewById(R.id.listView1);
ListAdapter adapter = new MyAdapter(this);
listview.setAdapter(adapter);
getdata();
}
public void getdata() {
try {
HttpClient httpClient = new DefaultHttpClient();
String urlStr = "http://211.83.105.83/test2/MobileHealth/OrdersListAction.aspx?UserID=123";
HttpPost post = new HttpPost(new URI(urlStr));
JSONObject json = new JSONObject();
json.put("UserID", 123);
json.put("UserName", "name1");
post.setEntity(new StringEntity(json.toString()));
HttpResponse httpResponse = httpClient.execute(post);
if (httpResponse.getStatusLine().getStatusCode() == 200) {
HttpEntity entity = httpResponse.getEntity();
if (entity != null) {
// 获取服务器响应的json字符串
String jsonobj = EntityUtils.toString(entity);
System.out.println("jsonobj:" + jsonobj);
// 解析从服务器返回的json
JSONObject obj = new JSONObject(jsonobj);
JSONArray forumobj = new JSONArray();
forumobj = obj.optJSONArray("datalist");
JSONArray arr = new JSONArray(forumobj.toString());
ArrayList shuzhangyalist = new ArrayList();
for (int i = 0; i < arr.length(); i++) {
JSONObject temp = (JSONObject) arr.get(i);
String shuzhangyadata = temp
.getString("DiastolicPressure");
shuzhangyalist.add(shuzhangyadata);
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
ListView listview = (ListView) findViewById(R.id.listView1);
ListAdapter adapter = new MyAdapter(this);
listview.setAdapter(adapter);
}
private class MyAdapter extends BaseAdapter {
private Context context;
private LayoutInflater inflater;
public ArrayList<String> arr;
public MyAdapter(Context context) {
super();
this.context = context;
inflater = LayoutInflater.from(context);
arr = new ArrayList<String>();
for (int i = 0; i < 7; i++) { // listview初始化3个子项
arr.add("");
}
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return arr.size();
}
@Override
public Object getItem(int arg0) {
// TODO Auto-generated method stub
return arg0;
}
@Override
public long getItemId(int arg0) {
