{
"json": {
"Songs": [
{
"song": "Song name ",
"Artist": "Sonjay singh",
"mp3": "http://c2lo.reverbnation.com/audio_player/download_song_direct/9140921.mp3"
},
{
"song": "SONG NAME",
"Artist": "aritist",
"mp3": "mp3_URL"
},
{
"song": "SONG NAME",
"Artist": "aritist",
"mp3": "mp3_URL"
}
]
}
}

Use this way to play audio songs
public class StreamAudioDemo extends Activity implements OnClickListener, OnPreparedListener, OnCompletionListener, OnErrorListener{
private MediaPlayer mp;
private ProgressDialog pd;
private Button btnplay;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
btnplay=(Button)findViewById(R.id.play);
btnplay.setOnClickListener(this);
}
@Override
public void onPrepared(MediaPlayer mp) {
Log.i("StreamAudioDemo", "prepare finished");
pd.setMessage("Playing.....");
mp.start();
}
@Override
public void onClick(View v) {
try
{
pd = new ProgressDialog(this);
pd.setMessage("Buffering.....");
pd.show();
mp = new MediaPlayer();
mp.setAudioStreamType(AudioManager.STREAM_MUSIC);
mp.setOnPreparedListener(this);
mp.setOnErrorListener(this); //http://www.youtube.com/watch?v=pj-T_LxSCng
mp.setDataSource("http://c2lo.reverbnation.com/audio_player/download_song_direct/9140921.mp3");
mp.prepareAsync();
mp.setOnCompletionListener(this);
}
catch(Exception e)
{
Log.e("StreamAudioDemo", e.getMessage());
}
}
@Override
public void onCompletion(MediaPlayer arg0) {
pd.dismiss();
Toast.makeText(getApplicationContext(), "Completed", Toast.LENGTH_LONG).show();
}
@Override
public boolean onError(MediaPlayer mp, int what, int extra) {
// TODO Auto-generated method stub
pd.dismiss();
return false;
}
}

使用Gson。它非常简单,创建一个具有相同变量名(class,artist,...)的类(比如classB),并使用classB变量列表创建另一个类(比如classC),然后分配它
Gson gson = new Gson();
Reader r = new InputStreamReader(strJson(url));
classC C = gson.fromJson(r,ClassC.class);
