Question

我发现此代码在我的项目中无效。

android:scrollbars="vertical"

但如果我将其设置为新的 DEMO ，则可行。我认为它是关于应用程序样式或build.gradle中的某些内容，但我尝试了很多方法而且它没有用（比如将应用程序样式从我的项目复制到新项目中）并应用它，它仍然有效），任何其他人有这个问题？这是我的build.gradle代码：

 android {
compileSdkVersion COMPILE_SDK_VERSION as int
buildToolsVersion BUILD_TOOLS_VERSION

    applicationId "com.haixue.app.android.HaixueAcademy.h4"

我明白了 @android：彩色/透明 SomeOthers在我们的应用程序样式中设置了此代码，此代码使ScrollBar透明。

我的应用程序的RecycleViews没有滚动条，但它适用于新项目
