Answer 1

使用GaugeField：net.rim.device.api.ui.component.GaugeField， 按照以下示例进行操作：http://docs.blackberry.com/en/developers/deliverables/18125/Gauge_field_1303006_11.jsp

Answer 2

使用BrowserFieldListener并在创建的类中使用以下两个函数：

public void documentCreated(BrowserField browserField, ScriptEngine scriptEngine, Document document) {
    try{
        System.out.println("Document Created");
            UiApplication.getUiApplication().invokeLater(new Runnable() { public void run() {
            Dialog.alert("Loading");
            }});
    } catch (Exception ex) { }
}

public void documentLoaded(BrowserField browserField, Document document) {
    try {
        System.out.println("Document loaded");
        UiApplication.getUiApplication().invokeLater(new Runnable() { public void run() {
            Dialog.alert("Finished Loading");
            }});
    } catch (Exception ex) { }
}
