【问题描述】：
我制作了一个在 PC 上运行良好的 Javafx 应用程序。现在，我尝试将其传输到 Android 智能手机。为此，我使用 JavaFXPorts (Gluon)、Eclipse 和 Gradle。
现在，我遇到了一个非常简单的例子：
void showPopUp() {
Button button = new Button("Action do do"));
HBox.setMargin(button , new Insets(10, 30, 10, 30));
button .setOnAction(e -> {
actionToDo();
});
Scene scene = new Scene (button, 100, 200);
Stage stage = new Stage();
stage.initModality(Modality.APPLICATION_MODAL);
stage.setScene(scene);
stage.show();
}
你知道原因吗？
谢谢
这是整个代码：
周期性任务（工作正常）
一个延迟的任务（它工作正常）
一个按钮“btn”，显示模态弹出窗口。它上面的触摸屏工作正常，可以进入弹出窗口
带有 2 个按钮 boutonPopUpA 和 boutonPopUpB 的 PopUp 添加到 HBOX boutonsMenuPrincipal
还有一个场景“连接到”boutonsMenuPrincipal
在弹出窗口中，boutonPopUpA 和 boutonPopUpB 显示但不活动（在触摸屏上未生成跟踪）

}
}
还有我的构建 gradle：
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'org.javafxports:jfxmobile-plugin:1.0.0-b10'
}
}
apply plugin: 'org.javafxports.jfxmobile'
repositories {
jcenter()
}
mainClassName = 'com.gluonapplication.GluonApplication'
jfxmobile {
android {
applicationPackage = 'com.gluonapplication'
manifest = 'src/android/AndroidManifest.xml'
androidSdk = 'C:/Users/pascal/AppData/Local/Android/sdk'
resDirectory = 'src/android/res'
compileSdkVersion = '23'
buildToolsVersion = '22.0.1'
}
ios {
infoPList = file('src/ios/Default-Info.plist')
}
}
【问题讨论】：
-
你能描述一下“卡住”是什么意思吗？您是否有错误，弹出窗口不显示...？您可以发布重现问题所需的代码吗？
-
你也可以发布你的 build.gradle 文件吗？
-
这里是 build.gradle 文件
