Java 此errormessage（使用或覆盖不推荐的API）是否与我的NullPointer异常相关

我面临这样的警告：

... uses or overrides a deprecated API. Recompile with -Xlint:deprecation for details does this warning

这是我第一次看到它。我在我的应用程序中遇到一些空问题，所以我想知道这个警告是否与我的问题有关

这是我面临警告的适配器 但是logcat告诉我，我在其他页面中也面临空值，所以是否都与此警告相关。提前谢谢

你有什么问题？任何堆栈跟踪？通常不推荐使用的API与NullPointerException无关，但您至少应该发布日志消息和注意到错误的行您有什么问题？任何堆栈跟踪？通常不推荐使用的API与NullPointerException无关，但您至少应该发布日志消息和注意到错误的行
