在Android上的模态窗口中没有检测到触摸屏按钮事件 [英] No detection of a touchScreen Button event in a modal window on Android
本文介绍了在Android上的模态窗口中没有检测到触摸屏按钮事件的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
现在，我被困在一个非常简单的例子中：
void showPopUp（）{
Button button = new Button（Action do do））;
HBox.setMargin（button，new Insets（10，30，10，30））;
按钮.setOnAction（e - > {
actionToDo（）;
}）;
场景场景=新场景（按钮，100,200）;
Stage stage = new Stage（）;
stage.initModality（Modality.APPLICATION_MODAL）;
stage.setScene（scene）;
stage.show（）;
}
你有理由的理由吗？
感谢
以下是 整个代码 ：
-
定期任务（正常工作）
-
延迟任务工作正常）
-
显示模态PopUp的按钮btn。触摸屏可以正常工作，并允许使用添加到HBOX boutonsMenuPrincipal的2个按钮boutonPopUpA和boutonPopUpB弹出PopUp
-
-
和一个舞台，其场景连接到boutonsMenuPrincipal
在popUp中，显示boutonPopUpA和boutonPopUpB但不活动（触摸屏上没有生成的跟踪）

解决方案
您需要更新jfxmobile插件版本。自从1.0.0-b10版本（一年半前）以来，许多事情已经修复和更新。
目前，版本是1.3.2。这不仅仅是插件，而是主要是javafxports的插件。 version包括。
如果您使用最喜爱的IDE上的Gluon插件，选择单一视图项目，您将获得最小项目模板和一个有效的 build.gradle 文件。
这是一个更新的构建脚本：
code> buildscript {
repositories {
jcenter（）
}
依赖关系{
classpath'org.javafxports：jfxmobile-plugin：1.3.2'
}
}
应用插件：'org.javafxports.jfxmobile'
存储库{
jcenter（）
maven {
url'http://nexus.gluonhq.com/nexus/content/repositories/releases'
}
}
mainClassName ='com.gluonhq.testtouch .TestTouch'
依赖关系{
编译'com.gluonhq：charm：4.3.0'
}
jfxmobile {
downConfig {
version ='3.2.0'
plugins'显示'，'生命周期'，'状态栏'，'存储'
}
和roid {
manifest ='src / android / AndroidManifest.xml'
}
}
您可以将所有代码添加到BasicView中，并将其部署在移动设备上并对其进行测试。
我刚刚完成，一切都正常：任务运行速度快，按钮响应。
使用JavaFXPorts不建议创建第二个 Stage 。您可以使用对话框（内置的JavaFX对话框或Gluon Mobile对话框）。
您可以测试Gluon Mobile图书馆免费，您将在启动时只收到一个Nag屏幕。
无论如何，您可以删除Gluon Mobile库（只需删除 com .gluonhq：charm：4.3.0 from dependencies），您将不得不将 MobileApplication 返回到常规JavaFX 应用程序并删除BasicView类（主要是你现在的）。
I made a Javafx application that works fine on PC. Now, I try to transfer it to Android Smartphone. To do that, I use JavaFXPorts (Gluon), with Eclipse and Gradle.
Now, I am stuck with a very simple example:
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();
}
Have you an idea of the reason?
Thanks
Here is the whole code with:
a periodic task (it works fine)
a delayed task (it works fine)
a button "btn" that displays the modal PopUp. The touchScreen on it works fine and allows to go to the PopUp
the PopUp with 2 buttons boutonPopUpA and boutonPopUpB that are added to the HBOX boutonsMenuPrincipal
and a stage with its scene "connected to" boutonsMenuPrincipal
In the popUp, boutonPopUpA and boutonPopUpB are displayed but inactive (No generated trace on a touchScreen)

jfxmobile {
android {

}
ios {

}
}
解决方案
You need to update the jfxmobile plugin version. Many things have been fixed and updated since the 1.0.0-b10 version (from a year and a half ago).
Currently the version is 1.3.2. It is not only the plugin, but the mainly the javafxports version that the plugin includes.
If you use the Gluon plugin on your favorite IDE, selecting a Single View project you will get the minimum project template and a valid build.gradle file.
This is an updated build script:
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'
}
}
You can add all your code to the BasicView, deploy it on mobile and test it.
I've just done it and everything works fine: the task runs fast, and the buttons are responsive.
Using JavaFXPorts it's not recommended creating a second Stage. You can use a Dialog (either built-in JavaFX dialog or Gluon Mobile dialog) instead.
You can test Gluon Mobile library for free, you will get only a nag screen at startup.
Anyway, you can remove the Gluon Mobile library (just remove com.gluonhq:charm:4.3.0 from dependencies), and you'll have to port back MobileApplication to a regular JavaFX Application and remove the BasicView class (mostly as you have now).
