I have worked all this afternoon on test applications, trying to
understand my problem.
I would like to explain my results, hoping to receive your help and
also to be useful to somebody.
So, using GWT 1.5.1 and an Android (beta version) emulator, I have
noticed that
1) I have problems transferring listboxes with dynamic content to
Android
For instance, in case I fill my listbox by invoking a remote-
procedure-call (RPC) to a service,
I cannot open the listbox properly. Here is the client-side code
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.setHorizontalAlignment(VerticalPanel.ALIGN_CENTER);
mainPanel.setVerticalAlignment(VerticalPanel.ALIGN_MIDDLE);
mainPanel.setSpacing(15);
actList.setWidth("100%");
mainPanel.add(img);
listService();
mainPanel.add(actList);
textReceiveBox.setVisibleLines(5);
textReceiveBox.setWidth("100%");
mainPanel.add(textReceiveBox);
textSendBox.setVisibleLines(2);
textSendBox.setWidth("100%");
mainPanel.add(textSendBox);
mainPanel.add(button);
}
public void listService (){
ListServiceAsync service = (ListServiceAsync)
GWT.create(ListService.class);
service.listService(new ListCallback());
}
public class ListCallback implements AsyncCallback {
public void onFailure(Throwable caught) {
GWT.log("Error ", caught);
caught.printStackTrace();
System.out.println("Unsuccessfull service");
}
public void onSuccess(Object result) {
System.out.println("Successfull service");
String[] list = (String[]) result;
for (int i = 0; i < list.length; i++) {
actList.addItem(list[i]);
}
}
}
}
