Android Studio“运行应用”对话框不会出现在一个项目中,而是出现在另一个项目中

我正在玩Android Studio制作一个非常简单的非常愚蠢的应用来学习保存关键偏好,我遇到了一个奇怪的障碍。我会尝试尽可能多地提供,因为它可能很难重现这个错误但老实说,我正在运行的两个应用程序都是超级基本并且没有编译错误

规格: 没有模拟器,我正在运行三星Galaxy平板电脑。 Windows 7,Android Studio 1.2,Gradle 2.2.1。

在问题标题中,我的意思是我有一个名为 Kitty 的项目(几乎是hello world和一个按钮)。我点击运行 - >'运行应用' - >(对话框打开) - > OK->应用程序在我的平板电脑上启动。

This is the box that I want to see!

^^^这是美丽的屏幕,我想看到共享偏好,但它只在 kitty 上。

现在我开始了另一个名为 SharedPreferences 的项目(要点:两个复选框要求你“你喜欢巧克力”和“你喜欢luigi”而你检查一个或两个都没有,然后按保存。两个文本视图在下面会更新,如果你喜欢这些东西,甚至以后如果你重新打开应用程序,textviews会记住Chocolate Luigi首选项)。这只是一个主要的活动。

我认为我没有更改两者之间的任何设置或项目偏好,也没有给我一个错误。 MainActivity.java 外观原始编辑

感谢您的帮助。我在浏览互联网时没有看到这个问题所以它可能是过分的菜鸟。

编辑:用较大的MainActivity类中唯一的onCreate重写

您似乎有两个onCreate方法。尝试删除第二个并再次运行它。

在Android Studio中,您需要在项目中创建一个运行配置。

转到左侧运行图标

的链接

Run Configuration

然后点击编辑配置,在Windows配置后如下:

Run configuration window

并保存,用于测试点击运行图标。
