Android ZXing改横屏识别为竖屏识别[转]
解决方法：
1.在DecodeHandler.java中，修改decode方法
? PlanarYUVLuminanceSource source = CameraManager.get().buildLuminanceSource(data, width, height);
为
??? byte[] rotatedData = new byte[data.length];
??? for (int y = 0; y < height; y++) {
??????? for (int x = 0; x < width; x++)
??????????? rotatedData[x * height + height - y - 1] = data[x + y * width];
??? }
??? int tmp = width; // Here we are swapping, that's the difference to #11
??? width = height;
??? height = tmp;
?? ?
??? PlanarYUVLuminanceSource source = CameraManager.get().buildLuminanceSource(rotatedData, width, height);
2.在CameraManager.java中，注释代码：
??????????? // rect.left = rect.left * cameraResolution.x / screenResolution.x;
??????????? // rect.right = rect.right * cameraResolution.x / screenResolution.x;
??????????? // rect.top = rect.top * cameraResolution.y / screenResolution.y;
??????????? // rect.bottom = rect.bottom * cameraResolution.y / screenResolution.y;
修改为
??????????? rect.left = rect.left * cameraResolution.y / screenResolution.x;
??????????? rect.right = rect.right * cameraResolution.y / screenResolution.x;
??????????? rect.top = rect.top * cameraResolution.x / screenResolution.y;
??????????? rect.bottom = rect.bottom * cameraResolution.x / screenResolution.y;
3.在CameraConfigurationManager.java中，在setDesiredCameraParameters方法中添加一句
? camera.setDisplayOrientation(90);
4.在AndroidManifest.xml中，把Activity的属性android:screenOrientation="landscape"
改为
? android:screenOrientation="portrait"
