如果我想在这个方法中使用它，如何从构造函数中获取应用程序？

Answer 1

如果你添加private val application你会在编译时出现异常

Accidental override: The following declarations have the same JVM signature

因此，要修复它，您只需在需要的地方调用 getApplication()。

SearchRecentSuggestions(getApplication(), MySuggestionsProvider.AUTHORITY, MySuggestionsProvider.MODE).clearHistory()
