एंड्रॉइड ऑडियो SeekBar

Question

मैं ऐसा कुछ बनाने की कोशिश कर रहा हूं जहां एक ऑडियो फ़ाइल खेला जाता है और इसे प्रगति/तलाश बार के साथ रोका जा सकता है और छेड़छाड़ की जा सकती है। मैं एक स्क्रीन को अधिकतर स्क्रीन लेना चाहता हूं और उसके बाद नीचे बाईं ओर एक प्ले पॉज़ बटन और बटन के दाईं ओर वाला बार चाहता हूं। सब कुछ तलाशबार काम करता है जो ऑडियो से लिंक नहीं है। मेरी प्रगति बार कोडिंग शायद एक गड़बड़ है क्योंकि अगर मैंने इंटरनेट पर कई लोगों को देखा है, लेकिन वे ज्यादातर मेरे लिए भ्रमित हैं क्योंकि वे संगीत प्लेयर ऐप्स के लिए हैं जो एक ऑडियो फाइल चलाने के लिए नहीं हैं।

कोई कृपया प्रगति पट्टी के साथ मेरी मदद कर सकता है? मेरे प्रोग्रामिंग में सुधार करने के लिए कोई अन्य सुझाव भी बहुत अच्छा होगा।

(मैं बहुत एंड्रॉयड और प्रोग्रामिंग करने के लिए नया हूँ सिर्फ चेतावनी देने के लिए)

यह मेरा जावा है:

    private Handler threadHandler = new Handler() { 
     public void handleMessage(Message msg) {

Answer 1

मुझे लगता है कि यह आपके लिए काम कर सकता है।

एक धागा है कि गीत की स्थिति की जाँच करेगा और इस तरह seekbar चले जाएँगे,

private Runnable moveSeekBarThread = new Runnable() { 

    public void run() { 
     if(mediaPlayer.isplaying){ 

     int mediaPos_new = mediaPlayer.getCurrentPosition(); 
     int mediaMax_new = mediaPlayer.getDuration(); 
     seekBar.setMax(mediaMax_new); 
     seekBar.setProgress(mediaPos_new); 

     handler.postDelayed(this, 100); //Looping the thread after 0.1 second 
             // seconds 
     } 
    } 
}; 

बनाएं और इस तरह है कि धागा फोन,

mediaPos = mediaPlayer.getCurrentPosition(); 
    mediaMax = mediaPlayer.getDuration(); 

    seekBar.setMax(mediaMax); // Set the Maximum range of the 
    seekBar.setProgress(mediaPos);// set current progress to song's 

    handler.removeCallbacks(moveSeekBarThread); 
    handler.postDelayed(moveSeekBarThread, 100);
