这个问题通常是由于没有正确引入布局绑定库所致。确保在build.gradle文件的android区域中包含以下属性：

buildFeatures {
    dataBinding true     
}

然后，在布局文件中添加以下代码：

最后，构建项目以生成布局绑定代码并使用它们：

// Create an instance of the binding or use the static method 'bind' as shown below.
ActivitySplitLayoutBinding binding = ActivitySplitLayoutBinding.inflate(getLayoutInflator());
// setContentView(binding.getRoot()); // Use this if you are in an Activity. Else use your relevant parent.
// Finally, you can set properties on views in your layout as follows
binding.textView.setText("Hello World");
