Question

我在Android设备上显示 JavaFX 上下文菜单时出现问题。它在桌面上工作正常，但在Android上应用程序崩溃。

Java代码段负责在用户按下按钮时显示我的示例上下文菜单：

public class MainButton implements EventHandler<ActionEvent>{

  @Override
  public void handle(ActionEvent event) {
    try{
        Controls.addDebugLine(event.getEventType().toString());
        Button button = (Button) event.getTarget();
        System.out.println(button);
        button.getContextMenu().show(button, Side.RIGHT, 0, 0);
    } catch (Exception e){
        Controls.addDebugLine(e.getMessage());         
    }
}

android log：
