Ho creato un file XML nel mio server. Contiene i tag title e link. Prendo i tag e li visualizzo come collegamenti in ListView. Da lì quando l'utente fa clic sul link, mi piacerebbe riprodurre il file .pls nell'app Radio Station.Come riprodurre l'url di streaming radio online su Android. Come giocare .pls radio streaming url in Android
Ecco il mio file XML:
<item>
<title> Kushi FM </title>
<link>http://108.163.197.114:8071/listen.pls</link>
</item>
non so come giocare il link nella prossima attività.

Grazie, tuttavia, quando l'utente fa clic sul nome Fm in Listview L'attività successiva verrà riprodotta automaticamente Come possiamo farlo ??? – vasanth
Ecco il codice che scrivo in NextActivity è giusto? Intento intent = getIntent(); stringa finale selectedData = intent.getStringExtra ("url"); fmname.setText (selectedData); mMediaPlayer = new MediaPlayer(); try { mMediaPlayer.setDataSource (selectedData); mMediaPlayer.prepareAsync(); mMediaPlayer.setOnPreparedListener (nuova MediaPlayer.OnPreparedListener() {public void onPrepared (MediaPlayer mp) { mMediaPlayer.start();} }); – vasanth
'Giocatore' L'attività dalla mia risposta sarà il tuo' Service_Player' nel metodo 'onCreate' di 'Player' activity che recupera i dati url dall'intenzione e il suo metodo di chiamata' startMediaPlayer' che avvierà il giocatore – user1140237
