Android 播放器开发之seekBar

核心提示：while(true){try {sleep(milliseconds);} catch (InterruptedException e) {// TODO Auto-generated catch blocke.printStackTrace();}mHandle.sendEmptyMessage(0);}}}//拖

while(true){

try {

sleep(milliseconds);

} catch (InterruptedException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

mHandle.sendEmptyMessage(0);

}

}

}

//拖动进度条更新

public void startProgressUpdate(){

//开辟Thread 用于定期刷新SeekBar

DelayThread dThread = new DelayThread(100);

dThread.start();

}

private Handler mHandle = new Handler(){

@Override

public void handleMessage(Message msg){

int position = mediaPlayer.getCurrentPosition();

int mMax = mediaPlayer.getDuration();

int sMax = seekBar.getMax();

seekBar.setProgress(position*sMax/mMax);

}

};
