在Android上的模态窗口中未检测到触摸屏按钮事件

标签: android events button javafx touchscreen

我制作了一个在PC上运行良好的Javafx应用程序。现在,我尝试将其转移到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?

感谢

以下是 整个代码

  • 定期任务(工作正常)

  • 延迟任务(工作正常)

  • 显示模式PopUp的按钮“btn”。它上面的touchScreen工作正常,允许转到PopUp

  • 带有2个按钮的PopUp boutonPopUpA和boutonPopUpB添加到HBOX boutonsMenuPrincipal

  • 以及其场景“连接到”boutonsMenuPrincipal的舞台

在popUp中,显示boutonPopUpA和boutonPopUpB但不活动(触摸屏上没有生成的跟踪)

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')
    }

您需要更新jfxmobile插件版本。自1.0.0-b10版本(一年半以前)以来,已修复和更新了许多内容。

目前version是1.3.2。它不仅是插件,而且主要是插件包含的javafxports version

如果您在自己喜欢的IDE上使用Gluon插件,选择单视图项目,您将获得最小的项目模板和有效的build.gradle文件。

这是一个更新的构建脚本:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'org.javafxports:jfxmobile-plugin:1.3.2'
    }
}

apply plugin: 'org.javafxports.jfxmobile'

repositories {
    jcenter()
    maven {
        url 'http://nexus.gluonhq.com/nexus/content/repositories/releases'
    }
}

mainClassName = 'com.gluonhq.testtouch.TestTouch'

dependencies {
    compile 'com.gluonhq:charm:4.3.0'
}

jfxmobile {
    downConfig {
        version = '3.2.0'
        plugins 'display', 'lifecycle', 'statusbar', 'storage'
    }
    android {
        manifest = 'src/android/AndroidManifest.xml'
    }
}

您可以将所有代码添加到BasicView,在移动设备上进行部署并对其进行测试。

我刚刚完成它并且一切正常:任务运行得很快,按钮响应很快。

使用JavaFXPorts不建议创建第二个Stage。您可以使用Dialog(内置JavaFX对话框或Gluon Mobile对话框)。

您可以免费测试Gluon Mobile库,启动时只能获得一个唠叨屏幕。

无论如何,您可以删除Gluon Mobile库(只需从依赖项中删除com.gluonhq:charm:4.3.0),然后您必须将MobileApplication移回常规JavaFX Application并删除BasicView上课(大部分和你现在一样)。
