How do I wait for the response is completed in another class?
For example, I have a class called GetData
public class GetData{
private String query;
private String DEFAULT_URL = "http://localhost/book.php";;
String result = new String();
public GetData(String query) {
this.query = query;
this.search();
}
private void search() {
String url = URL.encode(DEFAULT_URL + "?query=" + this.query);
RequestBuilder builder = new RequestBuilder(RequestBuilder.GET,
url);
builder.setCallback(new RequestCallback() {
public void onError(Request request, Throwable
exception) {
}
public void onResponseReceived(Request request,
Response response)
{
if (Response.SC_OK == response.getStatusCode())
{
result = response.getText();
}
}
});
try {
builder.send();
} catch (RequestException e) {
}
}
public String getResult(){
return this.result;
}
}
So, when I call
GetData test = new GetData(query);
System.out.println(test.getResult());
will return nothing. But I'm sure that it will return something.
The problem is System.out.println(test.getResult()); is executed
before the result=response.getText();
How can I fix that?
