我有一个自定义布局（扩展LinearLayout），它实现了TextToSpeech.OnInitListener接口。除非在Android Studio的编辑器中打开包含此布局的活动，否则一切正常。
预览渲染失败，因为Android Studio无法找到TextToSpeech.OnInitListener类：
java.lang.ClassNotFoundException: android.speech.tts.TextToSpeech$OnInitListener

我已经尝试重建，清除缓存，刷新布局，删除布局类的implements并将其替换为普通侦听器，并将每个与TTS相关的代码放入{{1阻止，没有成功。
你能帮帮我吗？
