我正在使用 Gluon Mobile 开发应用程序.最近我用 Presenter 创建了一个新 View ，将它添加到 AppViewManager.class，并且一切都在 Windows 上工作(当我使用“运行”gradle 构建脚本时)。但是当我在我的 Android 手机(Oppo，Android 8.1)上运行一个应用程序时，它会在切换到从另一个 View 触发的新 View 后崩溃:
private void showDomainInfo(TaskDomainModel task) {
System.out.println("CYBER_ESSENTIALS | going to start DOMAIN_VIEW...");
getApp().LastDomainModel = task;
AppViewManager.DOMAIN_VIEW.switchView();
}
应用程序崩溃，logcat 中没有任何有用的信息:

domainDetails.showingProperty().addListener((obs, oldValue, newValue) -> {
if (newValue) {
AppBar appBar = getApp().getAppBar();
appBar.setNavIcon(MaterialDesignIcon.ARROW_BACK.button(e ->
AppViewManager.DASHBOARD_VIEW.switchView()
));
appBar.setTitleText(getApp().LastDomainModel.getDomain());
appBar.getActionItems().add(MaterialDesignIcon.SHARE.button(e ->
System.out.println("Share")));
initVars();
}
});
}
private void initVars() {
domainInfoText.setText("Report for " + getApp().LastDomainModel.getCreated());
String cms = getApp().LastDomainModel.getCms();
if (cms.equalsIgnoreCase("")) cms = "Unrecognized / none";
cmsDetails.setText(cms);
categoryDetails.setText(getApp().LastDomainModel.getCategory());
subdomainsCardPane.getItems().addAll(getApp().LastDomainModel.getSubdomains());
nmapScanText.setText(getApp().LastDomainModel.getNmap());
whoisDetails.setText(getApp().LastDomainModel.getWhois());
}
}

IDK 如果那是一些与 Android 相关的问题，但它真的很奇怪。 期待您的帮助。
最佳答案
好了，问题解决了。 我按照 @josé-pereda 的建议用 try/catch 覆盖了代码
try {
AppViewManager.DOMAIN_VIEW.switchView();
} catch (Exception e) {
System.out.println("CYBER_ESSENTIALS | " + e);
}
并得到一个异常(exception):
java.lang.IllegalStateException: Cannot load com/CyberEssentials/views/domaindetails.fxml
这帮助我找到了这个答案 NullPointerException load fxml
它没有解决我的问题，但我开始研究我的 fxml 文件名和它的变量名。看起来 fxml 加载器不太喜欢文件名中的驼峰式大小写。
新 View 现在可用。
