使用5个surface在录像时能正常获取数据的代码

以下是使用5个surface在录像时能正常获取数据的代码示例：

private SurfaceView surfaceView1, surfaceView2, surfaceView3, surfaceView4, surfaceView5;
private MediaRecorder mediaRecorder;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    // 初始化SurfaceView
    surfaceView1 = findViewById(R.id.surfaceView1);
    surfaceView2 = findViewById(R.id.surfaceView2);
    surfaceView3 = findViewById(R.id.surfaceView3);
    surfaceView4 = findViewById(R.id.surfaceView4);
    surfaceView5 = findViewById(R.id.surfaceView5);

    // 绑定SurfaceHolder.Callback
    surfaceView1.getHolder().addCallback(surfaceHolderCallback);
    surfaceView2.getHolder().addCallback(surfaceHolderCallback);
    surfaceView3.getHolder().addCallback(surfaceHolderCallback);
    surfaceView4.getHolder().addCallback(surfaceHolderCallback);
    surfaceView5.getHolder().addCallback(surfaceHolderCallback);

    // 初始化MediaRecorder
    mediaRecorder = new MediaRecorder();
    mediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
    mediaRecorder.setVideoSource(MediaRecorder.VideoSource.SURFACE);
    mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
    mediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.H264);
    mediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AAC);
    mediaRecorder.setVideoEncodingBitRate(10000000);
    mediaRecorder.setVideoFrameRate(30);
    mediaRecorder.setVideoSize(640, 480);
    mediaRecorder.setOutputFile(getFilePath());

    try {
        mediaRecorder.prepare();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

// SurfaceHolder.Callback回调
private final SurfaceHolder.Callback surfaceHolderCallback = new SurfaceHolder.Callback() {
    @Override
    public void surfaceCreated(SurfaceHolder holder) {
        // 设置MediaRecorder的Surface
        mediaRecorder.setPreviewDisplay(holder.getSurface());
        // 开始录制
        mediaRecorder.start();
    }

    @Override
    public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {
        // do nothing
    }

    @Override
    public void surfaceDestroyed(SurfaceHolder holder) {
        // 停止录制
        mediaRecorder.stop();
        // 释放资源
        mediaRecorder.release();
        mediaRecorder = null;
    }
};

// 获取输出文件路径
private String getFilePath() {
    File dir = new File(Environment.getExternalStorageDirectory(), "MyApp");
    if (!dir.exists()) {
        dir.mkdirs();
    }
    return dir.getAbsolutePath() + "/video.mp4";
}

以上代码中，我们使用了5个SurfaceView，每个SurfaceView都绑定了相同的SurfaceHolder.Callback回调。在回调的surfaceCreated方法中，我们将MediaRecorder的PreviewDisplay设置为当前Surface的Surface，并调用start方法开始录制。在surfaceDestroyed方法中，我们停止录制，并释放资源。

需要注意的是，为了能够正常使用5个SurfaceView，需要在AndroidManifest.xml文件中添加以下权限：

<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
