Android SurfaceView+MediaPlayer 本地视频播放器(卡拉OK功能)
来源：互联网 发布：js 数组 按50为一批 编辑：程序博客网 时间：2024/05/18 02:39
功能情景:
1.播放视频文件
2.上一首，下一首
3.卡拉ok功能
4.播放模式（顺序，随机，循环）
效果图
功能的实现:
1.伴唱功能:(这里是mkv文件切换声道),伴唱转AUDIO,原唱转VIDEO。当然前提是先获得mkv文件的所有声道。
我在视频准备的时候获取所有声道，然后判断是否有这个声道我再转。
@Override public void onPrepared(MediaPlayer mediaPlayer) { //视频播放 mMediaPlayer.start(); //获取视屏的长度 tv_video.setText(ProjectUtils.formatTime(mMediaPlayer.getDuration())); // mIsStopped = false; if (iv_play != null) { iv_play.setSelected(false); } //获取所有的音轨 trackInfo = mMediaPlayer.getTrackInfo(); } //伴唱与原唱 RxView.clicks(iv_sing_state).throttleFirst(2, TimeUnit.SECONDS).subscribe(new Action1<Void>() { @Override public void call(Void aVoid) { int pos = fileName.lastIndexOf('.'); if (pos != -1) { String indexName = fileName.substring(pos); if (indexName.equalsIgnoreCase(".mkv")) { if (trackInfo != null) { Logger.i("fileName" + fileName); mMediaPlayer.selectTrack(MediaPlayer.TrackInfo.MEDIA_TRACK_TYPE_AUDIO); } if (!iv_sing_state.isSelected()){ boolean flag=false; for (int i = 0; i < trackInfo.length; i++) { if (trackInfo[i].getTrackType()== MediaPlayer.TrackInfo.MEDIA_TRACK_TYPE_AUDIO){ flag=true; } } if (flag){ //切换音轨(伴唱) if (mMediaPlayer!=null){ mMediaPlayer.selectTrack(MediaPlayer.TrackInfo.MEDIA_TRACK_TYPE_AUDIO); } } iv_sing_state.setSelected(true); }else{ boolean flag=false; for (int i = 0; i < trackInfo.length; i++) { if (trackInfo[i].getTrackType()== MediaPlayer.TrackInfo.MEDIA_TRACK_TYPE_VIDEO ){ flag=true; } } if (flag){ //原唱 if (mMediaPlayer!=null){ mMediaPlayer.selectTrack(MediaPlayer.TrackInfo.MEDIA_TRACK_TYPE_VIDEO); } } iv_sing_state.setSelected(false); } }else{ Toast.makeText(VideoPalyActivity.this,"不是卡拉OK文件，不具备伴唱功能",Toast.LENGTH_SHORT).show(); } } } });2.播放模式
随机模式的算法:当切换到随机模式时，先移除掉当前播放的数据，然后播放下一首的时候，从剩余的随机一条，然后再移除，再随机。知道没有数据，没有数据的时候再从新复制总数据。这里注意的是，可移除的数据集合必然是克隆原先数据集合的，而不是简单的复制（注意java的数据存储）
//播放模式的切换 RxView.clicks(iv_state).throttleFirst(2, TimeUnit.SECONDS).subscribe(new Action1<Void>() { @Override public void call(Void aVoid) { if (playMode == 1) { playMode = 2;//随机模式 Toast.makeText(VideoPalyActivity.this, "随机模式", Toast.LENGTH_SHORT).show(); iv_state.setImageResource(R.drawable.iv_state_suiji_press); } else if (playMode == 2) { playMode = 3;//循环模式 Toast.makeText(VideoPalyActivity.this, "循环模式", Toast.LENGTH_SHORT).show(); iv_state.setImageResource(R.drawable.iv_state_xunhuan_press); } else if (playMode == 3) { playMode = 1;//顺序模式 Toast.makeText(VideoPalyActivity.this, "顺序模式", Toast.LENGTH_SHORT).show(); iv_state.setImageResource(R.drawable.iv_state_shunxu_press); } } });播放模式要有效果必然要在播放完成下写算法
@Override public void onCompletion(MediaPlayer mp) { Toast.makeText(VideoPalyActivity.this, "播放完毕", Toast.LENGTH_SHORT).show(); seekBar.setProgress(100); RxUtils.unsubscribe(seekBarSubscription); if (iv_play != null) { iv_play.setSelected(true); } if (playMode == 1) { Logger.i(TAG, "播放完毕进入顺序模式"); if (currentPos < data.size()) { currentPos++; Logger.i("随机::666" + "currentPos=" + currentPos); if (currentPos<data.size()){ mVideoPath = data.get(currentPos).getAbsolutePath(); Logger.i("随机::666" + "mVideoPath=" + mVideoPath); fileName = data.get(currentPos).getName(); } } } else if (playMode == 2) { Logger.i(TAG, "播放完毕进入随机模式"); if (copydata.size() != 0) { int pos = -1; for (int i = 0; i < copydata.size(); i++) { if (copydata.get(i).getAbsolutePath().equals(mVideoPath)) { pos = i; } } if (pos != -1 && pos < copydata.size()) { copydata.remove(pos); } int max = copydata.size(); int min = 0; Random random = new Random(); int rNum = random.nextInt(max) % (max - min + 1) + min; mVideoPath = copydata.get(rNum).getAbsolutePath(); fileName = copydata.get(rNum).getName(); // mVideoPath = copydata.get(rNum).getFilepath(); for (int i = 0; i < data.size(); i++) { if (data.get(i).getAbsolutePath().equals(copydata.get(rNum).getAbsolutePath())) { currentPos = i; } } Logger.i("随机::555" + "currentPos=" + currentPos); mVideoPath = data.get(currentPos).getAbsolutePath(); fileName = data.get(currentPos).getName(); Logger.i("随机::555" + "mVideoPath=" + mVideoPath); copydata.remove(rNum); } else { copydata = (ArrayList<File>) data.clone(); } } else if (playMode == 3) { Logger.i(TAG, "播放完毕进入循环模式"); Logger.i("随机::777" + "currentPos=" + currentPos); Logger.i("随机::777" + "mVideoPath=" + mVideoPath); } prepare(); }附件：完整代码：
