在 AndroidX 中膨胀 SlidingPaneLayout 类时出错

Question

问题：

大家好，我有一个直截了当的问题。

我之前在AndroidX 中使用过androidx.slidingpanelayout.widget.SlidingPaneLayout，效果非常好。

但是现在，在我的另一个应用程序中，Android-Studio 给了我一个错误，基本上说它在膨胀 SlidingPaneLayout 类时遇到问题。

我做了什么：

• 我检查了每个依赖项，并将它与我以前使用它的应用程序进行了比较。

• 我多次重建我的项目并清理了它 (Build > Clean Project)。

• 我使用了以前版本的 material-design 依赖项并用它们编译了我的项目，但没有任何改变。

我使用过的依赖：

implementation 'androidx.appcompat:appcompat:1.1.0'
implementation 'com.google.android.material:material:1.1.0-alpha10'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test:runner:1.2.0'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'

请注意，我还尝试切换回我在其他应用中使用的 alpha09，但在这里它什么也没做。

错误：

我只是简单地复制并粘贴了下面的整个错误。

目标：

我只想能够在我现有的AndroidX 应用程序中使用SlidingPaneLayout。

Answer 1

只需在 build.gradle 文件中添加“implementation 'androidx.slidingpanelayout:slidingpanelayout:1.1.0'”即可。
