Android中使用Alerter库实现不同类型的AlertBox

在本文中，我们将实现一个与 AlertBox 相关的非常重要的功能。通常，我们创建一个 AlertBox 来显示一些重要的内容。在这里，我们将学习如何使用警报库在我们的 Android 应用程序中实现该功能。下面给出了一个示例视频，以了解我们将在本文中做什么。请注意，我们将使用Java语言来实现这个项目。

分步实施

第 1 步：创建一个新项目

要在 Android Studio 中创建新项目，请参阅如何在 Android Studio 中创建/启动新项目。请注意，选择Java作为编程语言。

第 2 步：添加依赖项和 JitPack 存储库

导航到Gradle Scripts > build.gradle(Module:app)并在依赖项部分添加以下依赖项。

implementation ‘com.tapadoo.android:alerter:2.0.4’

将 JitPack 存储库添加到您的构建文件中。将其添加到 allprojects{} 部分中存储库末尾的根 build.gradle 中。

allprojects {

 repositories {

   …

   maven { url “https://jitpack.io” }

     }

}

添加此依赖项后同步您的项目，现在我们将转向它的实现。

步骤 3：使用 activity_main.xml 文件

导航到app > res > layout > activity_main.xml并将以下代码添加到该文件中。下面是activity_main.xml文件的代码。

第 4 步：使用MainActivity。 Java文件

转到主活动。 Java文件，参考如下代码。下面是MainActivity的代码。 Java文件。代码中添加了注释以更详细地理解代码。
