getHostServices（）;找不到方法。

Question

我想使用下面的代码打开pdf文件，但方法是getHostServices（）;即使我有正确的进口，也找不到。

import javafx.application.HostServices;

ClinicFiles clinicFiles = (ClinicFiles) listViewClinic.getSelectionModel().getSelectedItem(); 
HostServices hostServices = getHostServices();
hostServices.showDocument(clinicFiles.getAbsolutePath());

Answer 1

您的课程可能不会从import javafx.application.Application; import javafx.application.HostServices; public class App extends Application { public void method(String[] args) { ClinicFiles clinicFiles = (ClinicFiles) listViewClinic.getSelectionModel().getSelectedItem(); HostServices hostServices = getHostServices(); hostServices.showDocument(clinicFiles.getAbsolutePath()); } }
