Answer 1

ここで、media.seekTo（position）を呼び出しましたか？私が見る限り、あなたはあなたの探検隊員にそのことを呼ばなかった。

そして、あなたは常にあなたの曲の進行にシークバーの相対位置を設定しているよう...それは常に戻って以前の状態に戻ります。..

ソリューション： あなたseekbarchangelistenerで...（メディアonSeekbarchangedを使用し、使用プレイヤー）.seekTo（位置）

Answer 2

try { 
         if (mediaPlayer.isPlaying() || mediaPlayer != null) { 
          if (fromUser) 
           mediaPlayer.seekTo(progress); 
         } else if (mediaPlayer == null) { 
          Toast.makeText(context.getApplicationContext(), "Media is not running", 
            Toast.LENGTH_SHORT).show(); 
          seekBar.setProgress(0); 
         } 
        } catch (Exception e) { 
         Log.e("seek bar", "" + e); 
         seekBar.setEnabled(false); 

        }
