解析JSON對象和數組我有這樣的JSON，我想在我的Android應用安卓

但我只能從logcat中獲得Reading a NULL string not supported here.。 因此，這裏是我的代碼，我用它來解析JSON：
// Creating JSON Parser instance
JSONParser jParser = new JSONParser();
// getting JSON string from URL
JSONObject json = jParser.getJSONFromUrl(url);
try {
// Getting Array of albums
albums = json.getJSONArray(TAG_ALBUMS);
// looping through All albums
for(int i = 0; i < albums.length(); i++){
JSONObject c = albums.getJSONObject(i);
// Storing each json item in variable
String album_id = c.getString(TAG_ID);
String album_name = c.getString(TAG_NAME);
String album_singer = c.getString(TAG_SINGER);
String album_genre = c.getString(TAG_GENRE);
String album_thumb = c.getString(TAG_THUMB);
// songs are again JSON Object
JSONObject songs = c.getJSONObject(TAG_SONGS);
String artist = songs.getString(TAG_SONG_ARTIST);
String mp3 = songs.getString(TAG_SONG_MP3);
String mp4 = songs.getString(TAG_SONG_MP4);
String song_thumb = songs.getString(TAG_SONG_THUMB);
String song_title = songs.getString(TAG_SONG_TITLE);
Log.v("--", "Albums \n"+" "+album_id+" "+album_name+" "+ album_genre+" "+album_singer+" "+album_thumb);
}
} catch (JSONException e) {
e.printStackTrace();
}
因此，誰能幫我解決這個問題。
你能給我更詳細的解決方案..謝謝你的回答 –
'歌曲'是一個JSON對象數組，其中每個對象都有標籤mp3，mp4，artist，thumb等。 – Swayam
除了歌曲部分之外，這樣做幾乎是正確的。所以，爲此，看看http://stackoverflow.com/questions/9529558/how-to-parse-this-json-array-in-android。 – Swayam
