camera.setDisplayOrientation(90);
不知道为什么,Zxing用的是横屏,也许是因为外国人习惯横屏拍照的原因把,但是,在国内,很多人不习惯,呵呵,我用着也不习惯.所以还是该成竖屏,以适合国内人的习惯吧.
修改方法:
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,修改代码:
// 注释掉 // 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; //修改成这样的 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"
