我希望用android studio做一款手机软件，开发要求如下：1.打开软件后自动打开手机后置摄像头并开始扫描快递单号条形码，如果扫描到快递单号条形码就启动录像2.点击结束录制按钮停止录像并以快递单号命名把视频保存到相册。3.保存完毕继续重复以上动作继续扫描4.请帮我写一下具体的项目结构和具体的代码作为参考5.不使用google play服务相关的库6.使用zbar

项目结构： - MainActivity：主界面，包含开始录制和结束录制按钮 - CameraActivity：相机界面，用于打开后置摄像头并开始扫描条形码 - VideoRecorder：视频录制类，用于录制视频并保存到相册 - BarcodeScanner：条形码扫描类，用于扫描快递单号条形码 具体代码示例： CameraActivity.java ```java public class CameraActivity extends AppCompatActivity { private CameraView cameraView; private BarcodeScanner barcodeScanner; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_camera); cameraView = findViewById(R.id.camera_view); barcodeScanner = new BarcodeScanner(this, cameraView); cameraView.addFrameProcessor(new FrameProcessor() { @Override public void processFrame(Frame frame) { barcodeScanner.scanBarcode(frame); } }); cameraView.start(); } @Override protected void onPause() { super.onPause(); cameraView.stop(); } @Override protected void onResume() { super.onResume(); cameraView.start(); } } ``` VideoRecorder.java ```java public class VideoRecorder { private MediaRecorder mediaRecorder; public void startRecording(String videoFileName) { mediaRecorder = new MediaRecorder(); mediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA); mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4); mediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.DEFAULT); mediaRecorder.setOutputFile(videoFileName); try { mediaRecorder.prepare(); mediaRecorder.start(); } catch (IOException e) { e.printStackTrace(); } } public void stopRecording() { mediaRecorder.stop(); mediaRecorder.release(); mediaRecorder = null; } } ``` BarcodeScanner.java ```java public class BarcodeScanner { private Context context; private CameraView cameraView; public BarcodeScanner(Context context, CameraView cameraView) { this.context = context; this.cameraView = cameraView; } public void scanBarcode(Frame frame) { // Use ZBar library to scan barcode // If barcode is detected, start recording video String barcodeData = decodeBarcode(frame); if (barcodeData != null) { String videoFileName = context.getExternalFilesDir(null).getAbsolutePath() + "/" + barcodeData + ".mp4"; VideoRecorder videoRecorder = new VideoRecorder(); videoRecorder.startRecording(videoFileName); } } private String decodeBarcode(Frame frame) { // ZBar barcode decoding logic here } } ``` 这只是一个简单的示例代码，实际开发中还需要处理权限请求、相机预览、错误处理等更多功能。希望这些代码能为你提供一些参考。 [2024-12-10 13:22:58 | AI写代码神器 | 1976点数解答]
