如何使用android midi库从midi文件中获取注释？

我已经尝试了android midi库提供的用于获取midi事件的示例，我想获取NoteOn事件中每个音符的音高，但结果似乎不是我想要的。我不知道LogCat中返回了什么信息

我不知道XXXX（YY）中的信息是什么：注意。分析的midi文件是“Mary有一只小羊羔”，所以我认为XXXX或YY都不会成为注释。这是返回的信息。请帮忙，谢谢

更新：

XXXX（YY）：NoteOn

与音符的音高无关，我发现返回消息中的数字25表示1/4拍。一对XXXX（455）和XXXX（25）代表一张纸币。后面的XXXX和前面的XXXX有一些算术关系，但我仍然不知道XXXX代表什么

有一个成员函数

getNoteValue（）

“…因此我认为XXXX或YY都不会是注释“为什么？”的意思@nonchip您可以看到以下示例。12480（25）：注意12935（455）：注意第一个数字在增加，第二个数字总是重复，我加载的midi文件是Mary had a little lamb，这两个数字和midi文件之间没有关系。谢谢，但是的，我知道。问题是我不知道如何使用它，因为在我的例子中，输入是一个MIDI文件，而不是我作为NoteOn值插入的音符。getNoteValue（）应该在setNoteValue（int p）之后使用，对吗？（我可能会误解），但是如何才能获得p的值？如果有办法得到p，那么getNoteValue（）将毫无用处，因为我已经得到了注释。当然，注释值就是注释值！库根据MIDI文件中的值创建了此对象。感谢您的回答，我无法理解您的观点。您的意思是midi文件中的音符（而不是插入的音符）可以使用NodeOn类存储？但是如何将note值设置到NodeOn变量中呢？你说的“inserted”是什么意思？您还没有显示任何插入任何内容的代码。库读取MIDI文件，构造适当的事件对象，并使用每个对象调用您的侦听器。感谢您的耐心，CL。我没有插入任何内容。我只是不知道如何使用这个库来获取便条…我有多蠢。。。但是我刚刚用JMusic.jar找到了一个，它可以工作。多么令人兴奋啊！！！你知道，我花了一天时间在这个问题上，却没能写出自己的方法。下面是我搜索的方法，希望它能帮助像我一样有同样问题的人：）
