java - 如何从这个 JSON 对象中获取艺术家姓名的值？

Question

我有以下 JSON 对象(抱歉长度太长)，我需要它来获取艺术家的姓名。它应该位于轨道 -> 项目 -> 专辑 -> 艺术家 -> 名称下。我正在尝试运行此代码，但无法获取艺术家姓名。以下是 JSON 对象的一部分:

{
  "tracks" : {
    "href" : "https://api.spotify.com/v1/search?query=closer&type=track&offset=0&limit=20",
    "items" : [ {
      "album" : {
        "album_type" : "single",
        "artists" : [ {
          "external_urls" : {
            "spotify" : "https://open.spotify.com/artist/69GGBxA162lTqCwzJG5jLp"
          },
          "href" : "https://api.spotify.com/v1/artists/69GGBxA162lTqCwzJG5jLp",
          "id" : "69GGBxA162lTqCwzJG5jLp",
          "name" : "The Chainsmokers",
          "type" : "artist",
          "uri" : "spotify:artist:69GGBxA162lTqCwzJG5jLp"
        } ],
        "available_markets" : [ "AD", "AR", "AT", "AU", "BE", "BG", "BO", "BR", "CA", "CH", "CL", "CO", "CR", "CY", "CZ", "DE", "DK", "DO", "EC", "EE", "ES", "FI", "FR", "GB", "GR", "GT", "HK", "HN", "HU", "ID", "IE", "IS", "IT", "JP", "LI", "LT", "LU", "LV", "MC", "MT", "MX", "MY", "NI", "NL", "NO", "NZ", "PA", "PE", "PH", "PL", "PT", "PY", "SE", "SG", "SK", "SV", "TR", "TW", "US", "UY" ],

......

我需要找到显示"name": "The Chainsmokers",的行，但我无法弄清楚。这是我到目前为止所拥有的:

JSONObject jObj;
JSONObject tracks;
JSONArray items;
JSONObject album;
JSONArray artists;
JSONObject aName;
jObj = new JSONObject(json);
tracks = (JSONObject) jObj.get("tracks");
items = (JSONArray) tracks.get("items");
String songName;
Log.d("searchSong", json);
// Return all of the results for the searched song. This will return to a ListView with the song name, uri, and artist name.
for (int i = 0; i < items.length(); i++) {
    try {
        songName = items.getJSONObject(i).getString("name");
        if (!(songName.toLowerCase().contains(query.toLowerCase()))) {
            continue;
        }
        // TODO THIS DOESN'T WORK!!!!
        // How do I get artistname????
        album = (JSONObject) items.getJSONObject(i).get("album");
        artists = album.getJSONArray("artists");    // get the artist name
        String artistsName = artists.getJSONObject(4).toString();
        String artistName = "";
        artistName = artists.getJSONObject(i).getString("name");

        // This stuff works
        id = items.getJSONObject(i).getString("id");
        lViewSearch.setVisibility(View.VISIBLE);
        lView.setVisibility(View.INVISIBLE);
        bNext.setVisibility(View.INVISIBLE);
        bPlay.setVisibility(View.INVISIBLE);
        searchSongs.add(songName + "\n" + id);
        searchAdapter.notifyDataSetChanged();
        svSong.clearFocus();
    } catch (JSONException e) {
        e.printStackTrace();
    }
} // end for loop

这是一个 for 循环，因为我需要获取所有歌曲，这里我只发布了其中一部分的 JSON 对象。如果您发现任何问题，请告诉我，谢谢!

什么是artists.getJSONObject(4)？您的数组似乎只显示数组中的一个对象。

应该只是...

artists.getJSONObject(0).getString("name")
