Question

所以我发现Rebol，我很高兴它在Android上运行。但是，当我创建GUI时，GUI首先弹出屏幕中央的左上角，我无法移动窗口或调整窗口大小。如果我将手机旋转到水平显示器，则窗口会自动调整到屏幕大小。然后我将手机旋转到垂直显示，窗口正确填充屏幕。

但是窗户上的一切都是微不足道的 - 几乎太小而无法通过手指敲击进行交互。

我还没有看到其他人抱怨这个问题。我该如何解决？我希望小部件显示与在手机上运行的每个其他应用程序相同的大小。而且，当然，正确打开窗口，这样我就不必旋转手机两次以使其正常显示，也很不错。

我为Android下载了Rebol（r3-droid.apk）here。

然后我下载了GUI支持here。

手机规格：

三星Galaxy Note 3
Android版本5.0

生成GUI的代码：

REBOL [title: "Widgets on Screen"]
do %r3-gui.r3
view [
    field
    area
    check
    radio
    text-list
    text-table
    drop-down
    button
]

Answer 1

查看演示。在底部字段中键入demo并运行它以查看如何调整面以适合屏幕大小。但正如giuliolunati所说，这个版本已经超过2年，并没有公开维护。

在我的HP 21“Android平板电脑上，面部的尺寸正确，但运行速度非常缓慢。

你最好的选择可能就是观看Red Android分支，它很快就会推出一款GUI。

Answer 2

对于未来的观看者，您可能需要调整gui-metric dpi。我发现有128个在Android Note3上工作。

gui-metric/set 'unit-size dpi / 128

Android上的Rebol GUI显示太小
