在我的应用程序中,我正在从服务器传输Mp3文件。流媒体和负载完美运行。但是媒体播放器中寻求的问题,
像我有2分钟的mp3,如果我已经加载它并且玩,猜缓冲去100%, 在玩了50%(意味着大约1分钟)后,我们寻求25%(意味着30秒), 玩家将从10秒开始,这是音乐播放器非常奇怪的行为我已经尝试了很多,但我在这里找不到任何解决方案,我现在感到沮丧,请帮助我谢谢
我的代码在
下面启动
MediaPlayer mPlayer = new MediaPlayer();
mPlayer.setWakeMode(_context, PowerManager.PARTIAL_WAKE_LOCK);
mPlayer.setOnPreparedListener(this);
mPlayer.setOnCompletionListener(this);
mPlayer.setOnErrorListener(this);
mPlayer.setOnInfoListener(this);
mPlayer.setOnBufferingUpdateListener(this);
musicseekbar =(SeekBar)findViewById(R.id.seekbar);
currenttime = (TextView)findViewById(R.id.runningtime);
totaltime = (TextView)findViewById(R.id.totaltime);
setSeekbar();
try {
mPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
} catch (Exception e) {
}
mPlayer.setDataSource(manualUrl);
mPlayer.prepareAsync();
其他stuf
private void setSeekbar() {
// TODO Auto-generated method stub
musicseekbar.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {
@Override
public void onStopTrackingTouch(SeekBar seekBar) {
// TODO Auto-generated method stub
}
@Override
public void onStartTrackingTouch(SeekBar seekBar) {
// TODO Auto-generated method stub
}
@Override
public void onProgressChanged(SeekBar seekBar, int progress,
boolean fromUser) {
// TODO Auto-generated method stub
if (fromUser) {
if (mPlayer != null && mPlayer.isPlaying()) {
MusicSeekto(progress,Globals.PlayerDuration);
seekBar.setProgress(progress);
}
}
}
});
}
public void setSeekBarpositionDetail(int position,int currenttime1,int totaltime1) {
// TODO Auto-generated method stub
if (musicseekbar != null) {
musicseekbar.setProgress(currenttime1);
}
}
public void setPlayerInfo(int duration) {
musicseekbar.setMax(duration); // set maximum here
}
public void MusicSeekto(int i, int playerDuration) {
// TODO Auto-generated method stub
if (mPlayer != null) {
mPlayer.seekTo(i); //problem is here , I get here exact "i", but seekto(pos) does't start from that position.
}
}
public void primarySeekBarProgressUpdater() {
if (mPlayer != null) {
stop = (int) (((float) mPlayer.getCurrentPosition() / Globals.PlayerDuration) * 100);
setSeekBarpositionDetail(stop, mPlayer.getCurrentPosition(), mPlayer.getDuration());
}
if (mPlayer != null) {
if (mPlayer.isPlaying()) {
notification = new Runnable() {
public void run() {
primarySeekBarProgressUpdater();
}
};
handler.postDelayed(notification, 100);
}
}
}
@Override
public void onPrepared(MediaPlayer mp) {
// TODO Auto-generated method stub
playerstarting();
primarySeekBarProgressUpdater();
}
private void playerstarting() {
// TODO Auto-generated method stub
if (mPlayer != null) {
mPlayer.start();
}
Globals.PlayerDuration = mPlayer.getDuration();
changingImage(false);
setPlayerInfo(mPlayer.getDuration());// seekbar value passing from here
}
答案 0 :(得分:0)
MediaPlayer.seekto不占百分比。这需要几毫秒。然而,你的百分比在传递。那不行。相反,尝试传入
((float)(i*mPlayer.getDuration()))/100.0
