4.视频seekBar进度更新

1.视频的总时长和SeekBar的setMaxt(总时长); 注意：准备好了的回调后

2.实例化Handler,每秒得到当前视频播放进度，SeekBar.setProgress(当前进度);

int duration = videoview.getDuration();
//把毫秒转换成 12:22.40
tv_duration.setText(utils.stringForTime(duration));

//设置视频的总长度为video_seekBar的多少等分
video_seekBar.setMax(duration);

//发消息开始更新
handler.sendEmptyMessage(PROGRESS);

5.实现视频的拖动

video_seekBar.setOnSeekBarChangeListener(newOnSeekBarChangeListener() {

//手指停止滑动的时候回调
@Override
public void onStopTrackingTouch(SeekBar seekBar) {
}

//手指刚开始滑动的时候回调
@Override
public void onStartTrackingTouch(SeekBar seekBar) {
}

//手指滑动状态发送变化的时候回调
@Override
public void onProgressChanged(SeekBar seekBar, int progress,booleanfromUser) {
if(fromUser){
//          seekBar.setProgress(progress);
videoview.seekTo(progress);
}
}

});
