我有个问题。我想在 x 秒后停止 httpconnection，我该怎么做？我认为类似 timertask 的东西会在 x 秒后执行 httpconnection.close() 或类似的东西。这是我使用连接的代码。
public void run() {
boolean hasCoverage = (RadioInfo.getState() == RadioInfo.STATE_ON)
&& (RadioInfo.getSignalLevel() != RadioInfo.LEVEL_NO_COVERAGE);
if (hasCoverage) {
UiApplication.getUiApplication().invokeLater(new Runnable() {
public void run() {
popup = new MyPopup("Cargando Incidentes...");
UiApplication.getUiApplication().pushModalScreen(popup);
}
});
try {
HttpConnection conn = null;
String URL = "anypage.php";
conn = (HttpConnection) Connector.open(URL);
InputStream contentIn = conn.openInputStream();
byte[] data = new byte[400];
int length = 0;
StringBuffer raw = new StringBuffer();
while (-1 != (length = contentIn.read(data))) {
raw.append(new String(data, 0, length));
str = raw.toString();
}
} catch (Exception e) {
e.printStackTrace();
mainScreen.add(new RichTextField(
"Error ThreadIncidentesConnection: " + e.toString()));
}
UiApplication.getUiApplication().invokeLater(new Runnable() {
public void run() {
try {
String datos[] = mainScreen.split(str, "ENDOFPAGE");
// mainScreen.add(new RichTextField(""+datos[0]));
datos[0] = datos[0].substring(2, datos[0].length());
mainScreen.vecRegistro = mainScreen
.split(datos[0], "$");
mainScreen.insertoEnBd();
mainScreen.insertoEnTablaDatosBD(_act);
UiApplication.getUiApplication().popScreen(popup);
} catch (Exception e) {
e.printStackTrace();
mainScreen.add(new RichTextField(
"Error ThreadIncidentes.run: " + e.toString()));
}
}
});
} else {
mainScreen.add(new RichTextField("No hay conexión disponible."));
}
}
