मैंने अपने सर्वर में एक एक्सएमएल फाइल बनाई है। इसमें title और link टैग शामिल हैं। मैं टैग लाता हूं और उन्हें ListView में लिंक के रूप में प्रदर्शित करता हूं। वहां से जब उपयोगकर्ता लिंक पर क्लिक करता है, तो मैं रेडियो स्टेशन ऐप में .pls फ़ाइल खेलना चाहता हूं।एंड्रॉइड में रेडियो स्ट्रीमिंग यूआरएल ऑनलाइन खेलने के लिए। एंड्रॉइड में .pls रेडियो स्ट्रीमिंग यूआरएल कैसे खेलें

मैं कैसे अगले गतिविधि में लिंक खेलने के लिए पता नहीं है:
यहाँ मेरी एक्सएमएल फ़ाइल है।

धन्यवाद लेकिन जब उपयोगकर्ता सूचीदृश्य में एफएम नाम पर क्लिक करें अगली गतिविधि स्वचालित रूप से खेलेंगी हम इसे कैसे कर सकते हैं ??? – vasanth
यहां अगली एक्टिविटी में कोड I लिखना सही है? इरादा इरादा = getIntent(); अंतिम स्ट्रिंग चयनित डेटा = intent.getStringExtra ("url"); fmname.setText (चयनित डेटा); mMediaPlayer = नया मीडियाप्लेयर(); { mMediaPlayer.setDataSource (चयनित डेटा) का प्रयास करें; mMediaPlayer.prepareAsync(); mMediaPlayer.setOnPreparedListener (नई MediaPlayer.OnPreparedListener() { सार्वजनिक शून्य onPrepared (MediaPlayer mp) { mMediaPlayer.start();} }); – vasanth
