Java 重命名包并更改主活动后，应用程序崩溃

我已经制作了一个关于旅行的应用程序，但在我重新命名了程序包并更改了活动顺序后，我的应用程序出现了问题。我收到错误“应用程序一直停止”。这是我的日志

我建议您使用正确的名称创建另一个项目，并将所有数据传递给新项目，因为android studio在运行时使用您的包名创建许多文件和路由，但如果您只需要更改应用程序id，您可以在gradle文件中更改此信息

android {
    defaultConfig {
        applicationId "com.example.myapp"
        minSdkVersion 16
        targetSdkVersion 24
        versionCode 1
        versionName "1.0"
    }
    ...
}

原因：android.view.InflateException:Binary-XML文件行#31:Binary-XML文件行#31:android.support.design.widget.EditText类膨胀错误

在

LoginActivity

中传递给

setContentView（）

的布局中似乎有一个

元素。没有像android.support.design.widget.EditText这样的

视图

。你的意思是

？你忘了重命名你的包了吗？有3个不同的地方（gradle-Mainactivity-package it self）你的LoginActivity布局中的编辑文本有一些问题。请发布您的xml文件。
