我正在做一个项目,我需要调用一个AsyncTask
,但onPostExecute
没有调用该方法。
这是我的课:
public class WebService extends AsyncTask<String, String, String> {
private ArrayList<SimpleObserver> listeners;
private int responseCode;
private String message;
private String response;
private String URL;
public WebService() {
listeners = new ArrayList<SimpleObserver>();
}
public void addListener(SimpleObserver obs) {
listeners.add(obs);
}
public void removeListener(SimpleObserver obs) {
listeners.remove(obs);
}
public void notifyListener(String s) {
for (SimpleObserver listener : listeners)
listener.onChange(s);
}
public String getResponse() {
return response;
}
public String getErrorMessage() {
return message;
}
public int getResponseCode() {
return responseCode;
}
@Override
protected void onPreExecute() {
//notifyListener("A calcular");
}
@Override
protected String doInBackground(String... urls) {
String response = "";
for (String url : urls) {
HttpParams my_httpParams = new BasicHttpParams();
final String proxyHost = android.net.Proxy.getDefaultHost();
final int proxyPort = android.net.Proxy.getDefaultPort();
if(proxyPort != -1)
{
my_httpParams.setParameter(ConnRoutePNames.DEFAULT_PROXY, new HttpHost(proxyHost, proxyPort));
}
DefaultHttpClient client = new DefaultHttpClient(my_httpParams);
HttpGet httpGet = new HttpGet(url);
Log.d("URL serviço HttpGet", url);
try {
HttpResponse execute = client.execute(httpGet);
InputStream content = execute.getEntity().getContent();
BufferedReader buffer = new BufferedReader(
new InputStreamReader(content));
String s = "";
while ((s = buffer.readLine()) != null) {
response += s;
}
Log.d("RESPOSTA do web service", response);
} catch (Exception e) {
e.printStackTrace();
response = e.getMessage();
Log.e("ERRO de respota", e.getMessage());
}
}
return response;
}
@Override
protected void onPostExecute(String result) {
Log.d("onPostExecute Serviço", result);
notifyListener(result);
}
}
我创建了这个方法:
public void executeService(String param) {
try {
Log.d("Entrar", "no serviço");
s.execute(new String [] {URL+param});
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
Log.e("Erro ao aceder ao web service", e.getMessage());
}
}
调用任务。
这些是日志的结果
08-28 17:47:21.936: D/URL serviço HttpGet(2055): http://192.168.56.1:8080/pt.Agile21.Acerola.WebService/rest/acerola?id=g;ana@eu.com
08-28 17:47:22.456: D/RESPOSTA do web service(2055): ana;ana@eu.com;pass;0
08-28 17:47:22.456: D/RESPOSTA do web service(2055): ana;ana@eu.com;pass;0
如您所见,我得到了 doInBackground() 的所有结果。:S
有人可以帮我理解是哪个问题吗?
我现在看到的东西正在寻找日志文件..当我故意完成我的应用程序时,我的 onPostExeute 方法返回..这是不正常的..:有人可以帮助我吗?
