java.lang.ClassCastException:android.app.ContextImpl

我正在尝试将ScoreNinja融入我的小游戏：

但是，每次都会引发运行时异常：

这是第31行：

scoreNinjaAdapter = new ScoreNinjaAdapter(getBaseContext(), "cockpushups", "71A7AD115870BA0E05C13BE2B9D3F984");

---

我使用的上下文可能有问题。任何帮助都将不胜感激

如果查看ScoreNinjaAdapter的代码，它会将上下文强制转换为

活动

。尝试使用

this

而不是

getBaseContext

，因为您是从活动中调用的。

另外，我是否应该更改我用于SoundManager的另一个getBaseContext？老实说，我不知道我曾经使用过getBaseContext。我现在找不到它，但我读过谷歌的一篇博文，其中有人直截了当地说“不要使用它”。

scoreNinjaAdapter = new ScoreNinjaAdapter(getBaseContext(), "cockpushups", "71A7AD115870BA0E05C13BE2B9D3F984");
