我正在尝试将图像视图设置为从网址中获取的位图,但是在运行以下代码后会出现以下堆栈跟踪:
public Bitmap getAlbumCover(Context context, String song, String artist) {
this.context = context;
song = song.replace(" ", "%20");
artist = artist.replace(" ", "%20");
final String finalSong = song;
final String finalArtist = artist;
Thread thread = new Thread(new Runnable() {
@Override
public void run() {
try {
ObjectMapper mapper = new ObjectMapper();
Document doc = Jsoup.connect("http://api.spotify.com/v1/search?q=track:" + finalSong + "%20artist:" + finalArtist+"%20" + "&type=track").ignoreContentType(true).get();
String body = String.valueOf(doc.body().text());
JsonNode readTree = mapper.readTree(body);
albumArt = readTree.findPath("url");
try {
URL url = new URL(albumArt.toString());
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoInput(true);
connection.connect();
InputStream input = connection.getInputStream();
albumImage = BitmapFactory.decodeStream(input);
} catch (Exception e) {
Log.e("Error", e.getMessage());
e.printStackTrace();
}
} catch (JsonGenerationException e) {
e.printStackTrace();
} catch (JsonMappingException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
});
thread.start();
Log.i("icon", "i"+ albumImage);
return albumImage;
}
这是堆栈跟踪:

链接在这里:https://i.scdn.co/image/9c2c4a9ac9726bfd996ff96383178bbb5efc59ab 如果单击它,它会拉出图像。我究竟做错了什么?我已经尝试过以UTF-8编码URL。
编辑:
记录专辑封面返回:我/专辑封面:“https://i.scdn.co/image/bf44daf8c3f35de83e5875bc49791c1347ef36f0”
答案 0 :(得分:1)
我做错了什么?
您在此行中调用了错误的albumArt
方法:URL url = new URL(albumArt.toString());
。您应该致电albumArt.getTextValue()
而不是albumArt.toString()
。
<强>为什么强>:
toString()
提供JsonNode
的字符串格式,在您的情况下为字符串&#34; \&#34; https://i.scdn.co/image/9c2c4a9ac9726bfd996ff96383178bbb5efc59ab \&#34; &#34; 即可。
相反,getTextValue()
会提供字符串&#34; https://i.scdn.co/image/9c2c4a9ac9726bfd996ff96383178bbb5efc59ab &#34; ,这是URL
想要的内容。
看到区别?
