On* productIdList.add(p.getId()); * 这行它说不能在以不同方法定义的内部类中引用非最终变量 productIdlist。
这是代码:
public ArrayList<String> getProductData() {
ArrayList<String> productIdList = new ArrayList<String>();
new Thread(new Runnable() {
public void run() {
HttpClient httpclient= new DefaultHttpClient();
GeneralConstans GC = new GeneralConstans();
// Products will be stated in memory
HttpPost httpget = new HttpPost(GC.UrlConstants);
HttpResponse response;
String result = null;
try {
HttpContext ctx = new BasicHttpContext();
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(
2);
httpget.setEntity(new UrlEncodedFormEntity(nameValuePairs,
"UTF-8"));
response = httpclient.execute(httpget, ctx);
HttpEntity resEntity = response.getEntity();
if (resEntity != null) {
result = EntityUtils.toString(resEntity);
JSONArray arr = new JSONArray(result);
Gson gson = new Gson();
if (arr.length() > 0) {
for (int j = 0; j < arr.length(); j++) {
Product p = gson.fromJson(arr.getString(j),
Product.class);
productIdList.add(p.getId());
}
}
}
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (SocketException e) {
/*if (checkAbortStatus(e.getMessage()) == true) {
handler.sendEmptyMessage(0);
}*/
} catch (IOException e) {
/*if (checkAbortStatus(e.getMessage()) == true) {
handler.sendEmptyMessage(0);
}*/
e.printStackTrace();
} catch (JSONException e) {
e.printStackTrace();
}
}
private Handler handler = new Handler() {
@Override
public void handleMessage(Message msg) {
super.handleMessage(msg);
}
};
}).start();
return productIdList;
有什么问题我该如何解决?提前致谢。
