如何在onComplete中添加TOAST消息，我是Android Studio的乞丐，对java知之甚少
下载完成后，我想在我的应用程序中显示Toast消息。我在互联网上获取了代码，它的工作原理如下：-应用程序正在从服务器下载视频，之后，它在视频中添加了我自己的水印，它工作得很好，但现在我想在完成添加水印的事情后显示TOAST消息。我添加了一个简单的Toast代码，但在完成水印处理应用程序后，它会因为简单的Toast消息而自动关闭，因此任何人都可以帮助解决其编码问题，如果您需要任何其他信息，请告诉我 这是我的JAVA类的全部代码 公共类下载服务扩展服务{如何在onComplete中添加TOAST消息，我是Android Studio的乞丐，对java知之甚少,java,firebase,android-studio,android-activity,Java,Firebase,Android Studio,Android Activity,下载完成后，我想在我的应用程序中显示Toast消息。我在互联网上获取了代码，它的工作原理如下：-应用程序正在从服务器下载视频，之后，它在视频中添加了我自己的水印，它工作得很好，但现在我想在完成添加水印的事情后显示TOAST消息。我添加了一个简单的Toast代码，但在完成水印处理应用程序后，它会因为简单的Toast消息而自动关闭，因此任何人都可以帮助解决其编码问题，如果您需要任何其他信息，请告诉我 这是我的JAVA类的全部代码 公共类下载服务扩展服务{ private DatabaseHandle
