我是android studio的新手，如有任何误解请多多包涵。我想在名为 lyrics_view 的 TextView 中显示一串音乐歌词，该 TextView 位于我的 fragment_lyrics.xml 文件中。我环顾四周并遵循了一些类似的例子，但没有运气解决我的问题。这是我的一些代码。当我点击播放按钮时，一首歌曲通过 Spotify api 播放，我还想使用 musixMatch api 将这些歌词显示到 lyrics_view 中。如果需要，我可以提供更多代码。我什至要正确显示这个字符串吗？或者我应该采取完全不同的方式？感谢您为这篇长帖子所做的努力。
playSongButton() 位于我的 MainActivity 类中。它负责播放歌曲并调用calculateLyrics()方法。
public void playSongButton(View view) {
try {
mPlayer.playUri(null, "spotify:track:15vzANxN8G9wWfwAJLLMCg", 0, 0);
//where i believe i am having issues
TextView textView = null;
TextView displayTextView = (TextView) findViewById(R.id.lyrics_view);
String lyricString = songLyrics.calculateLyrics();
displayTextView.setText(lyricString);
} catch (Exception e) {
e.printStackTrace();
}
}
CalculateLyrics() 属于 SongLyrics 类
public SongLyrics(String songName, String artistName) {
this.songName = "Paris";
this.artistName = "The Chainsmokers";
}
public String calculateLyrics() {
try {
musixMatch = new MusixMatch(key.getKey());
track = musixMatch.getMatchingTrack(songName, artistName);
trackData = track.getTrack();
trackId = trackData.getTrackId();
lyrics = musixMatch.getLyrics(trackId);
lyricString = lyrics.getLyricsBody();
} catch (Exception e) {
e.printStackTrace();
}
return lyricString;
}

最佳答案
您需要将查询结果过滤到 musixmatch。当我与艺术家 The Chainsmokers 一起运行 curl 命令并跟踪 Paris 时，您会收到 musixmatch 返回的 20 首轨道(大部分是俱乐部混音)。您必须编写一些代码来使用用户文档中提到的过滤器参数(f_输入参数)查找/过滤结果到您想要显示的结果
