1) Sorry, I closed my post involuntarily.
Keeping at point 1), here is the server-side code:
import java.util.Vector;
import com.google.gwt.user.server.rpc.RemoteServiceServlet;
public class ListServiceImpl extends RemoteServiceServlet
implements ListService {
private String[] list = {"thank","you","for","help"};
public String[] listService() {
String[] vector = {"","","",""};
for (int i=0; i < list.length; i++){
vector[i] = list[i];
}
return vector;
}
}
Obviously you have to define also a ListService and a
ListServiceAsync interface on client-side:
import com.google.gwt.core.client.GWT;
import com.google.gwt.user.client.rpc.RemoteService;
import com.google.gwt.user.client.rpc.RemoteServiceRelativePath;
import com.google.gwt.user.client.rpc.ServiceDefTarget;
@RemoteServiceRelativePath("ListService")
public interface ListService extends RemoteService {
public String[] listService();
public static class Util {
public static ListServiceAsync getInstance() {
return GWT.create(ListService.class);
}
}
}
import com.google.gwt.user.client.rpc.AsyncCallback;
public interface ListServiceAsync {
public void listService(AsyncCallback<String[]> callback);
}
I can say that differently from version alpha of Android (and from
many browsers I used), the beta version of Android has an exception on
the abovementioned code:
[WARN] StandardContext[]Exception while dispatching incoming RPC
call
java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
I don't understand why
2) I often neither can click on simple list-boxes with 'static'
content (invoking no services no server-side). See for reference the
following GWT code:
here I have programmed a very simple and ugly UI. I cannot either
click (on Android version beta) on the listbox which is on the top of
the UI.
I remove the problem if only I remove the invocation
mainPanel.setBorderWidth(1): WHY???
import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.core.client.GWT;
import com.google.gwt.user.client.rpc.AsyncCallback;
import com.google.gwt.user.client.rpc.ServiceDefTarget;
import com.google.gwt.user.client.ui.Button;
import com.google.gwt.user.client.ui.Image;
import com.google.gwt.user.client.ui.ListBox;
import com.google.gwt.user.client.ui.RootPanel;
import com.google.gwt.user.client.ui.TextArea;
import com.google.gwt.user.client.ui.VerticalPanel;
public class NewAndroid implements EntryPoint {
public VerticalPanel backPanel = new VerticalPanel();
public VerticalPanel mainPanel = new VerticalPanel();
public ListBox actList = new ListBox();
public TextArea textSendBox = new TextArea();
public TextArea textReceiveBox = new TextArea();
public Button button = new Button ("Send");
public Image img = new Image("");
public void onModuleLoad(){
RootPanel.get().add(mainPanel);
mainPanel.setBorderWidth(1);
mainPanel.setHorizontalAlignment(VerticalPanel.ALIGN_CENTER);
mainPanel.setVerticalAlignment(VerticalPanel.ALIGN_MIDDLE);
mainPanel.setSpacing(15);
actList.setWidth("100%");
mainPanel.add(img);
mainPanel.add(actList);
textReceiveBox.setReadOnly(true);
textReceiveBox.setVisibleLines(5);
textReceiveBox.setWidth("100%");
mainPanel.add(textReceiveBox);
textSendBox.setVisibleLines(2);
textSendBox.setWidth("100%");
mainPanel.add(textSendBox);
mainPanel.add(button);
}
Thank you in advance,
