您可以使用mediaRecorder API。这里有一个简单的例子：

公共类扩展活动实现了OnClickListener，SurfaceHolder.Callback { MediaRecorder记录器；SurfaceHolder持有者；布尔记录= false；@Override void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState)；SurfaceHolder.Callback getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN，WindowManager.LayoutParams.FLAG_FULLSCREEN；setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE)；记录器=新MediaRecorder()；initRecorder()；setContentView(R.layout.main)；SurfaceView cameraView = (SurfaceView) findViewById(R.id.CameraView)；holder = cameraView.getHolder()；holder.addCallback(this)；holder.addCallback cameraView.setClickable(真)；cameraView.setOnClickListener(this)；{ recorder.setAudioSource(MediaRecorder.AudioSource.DEFAULT)；recorder.setVideoSource(MediaRecorder.VideoSource.DEFAULT)；CamcorderProfile cpHigh = CamcorderProfile .get(CamcorderProfile.QUALITY_HIGH)；recorder.setProfile(cpHigh)；recorder.setOutputFile("/sdcard/videocapture_example.mp4")；recorder.setMaxDuration(50000)；// 50秒recorder.setMaxFileSize(5000000)；//大约5兆字节}私有prepareRecorder() { recorder.prepare()；}recorder.prepare()；} catch (IllegalStateException e) { e.printStackTrace()；}onClick(视图v) { if (记录){ recorder.stop()；initRecorder = false；//让我们重新记录initRecorder()；prepareRecorder()；}initRecorder= true；recorder.start()；}公共空洞surfaceCreated(SurfaceHolder holder) { prepareRecorder()；}公共空洞surfaceChanged(SurfaceHolder holder，int格式，int宽度，int高度){}公共空(SurfaceHolder holder) { if ( recording ) { recorder.stop()；SurfaceHolder= false；} recorder.release()；完成()；}
