我已经制作了关于旅行的应用程序，但是在我重命名包并更改了活动的顺序后，我的应用程序出现了问题。我收到错误“应用程序不断停止”。这是我的日志。

Caused by: android.view.InflateException: Binary XML file line #31: Binary XML file line #31: Error inflating class android.support.design.widget.EditText
看起来您在布局中有一个<android.support.design.widget.EditText> 元素，您将在LoginActivity 中传递给setContentView()。没有像android.support.design.widget.EditText 这样的View。你的意思是<android.support.design.widget.TextInputEditText>？
你是否忘记了重命名你的包的任何事情——有 3 个不同的地方（gradle - Mainactivity - package it self）
LoginActivity 布局中的 EditText 存在问题。请发布您的 xml 文件。

【解决方案1】：

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称创建许多文件和路由，但如果您只需要更改应用程序 ID，您可以在你的 gradle 文件。

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