[移动开发]Android MediaPlayer结合Seekbar实现音频文件播放

MediaPlayer和Seekbar

<SeekBar
            android:id="@+id/voice_progress"
            android:layout_width="180dp"
            android:layout_height="wrap_content"
            android:background="@android:color/transparent"
            android:progressTint="#22C580"
            android:thumbTint="#22C580"
            android:maxHeight="2dip"
            android:minHeight="2dip"
            android:paddingLeft="0dip"
            android:paddingRight="0dip"/>
thumbTint //滑块颜色              
progressTint //进度条颜色            

//初始化MediaPlayer
mMediaPlayer = new MediaPlayer();
//播放完成监听
mMediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener()
//设置播放文件源
mMediaPlayer.setDataSource(audioFile.getAbsolutePath());
mMediaPlayer.prepare();
mMediaPlayer.start();
//设置不循环播放
mMediaPlayer.setLooping(false);
//设置seekbar长度
mSeekBar.setMax(mMediaPlayer.getDuration());
//获取当前播放进度
int currentSecond = mMediaPlayer.getCurrentPosition();
//设置seekbar上进度
mSeekBar.setProgress(currentSecond);

//Seekbar手动滑动播放
实现SeekBar.OnSeekBarChangeListener接口，重写一下三个方法
    
@Override
    public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
        if(fromUser){
            mCurrentTime.setText(NoteUtils.secondToTime(progress/1000)+"/");
        }
    }

    @Override
    public void onStartTrackingTouch(SeekBar seekBar) {
        voiceHandler.removeMessages(UPDATE_SEEKBAR_PROGRESS);
    }

    @Override
    public void onStopTrackingTouch(SeekBar seekBar) {
        //指定开始播放位置
        mMediaPlayer.seekTo(seekBar.getProgress());
        if (mMediaPlayer.isPlaying()) {
            voiceHandler.removeMessages(UPDATE_SEEKBAR_PROGRESS);
            voiceHandler.sendEmptyMessage(UPDATE_SEEKBAR_PROGRESS);
        }
    }
