完美解決Android使用Zxing掃描二維碼改成豎屏後,後面的預覽畫面出現了拉伸,扭曲的情況

完美解決解決Android使用Zxing掃描二維碼改成豎屏後,後面的預覽畫面出現了拉伸,扭曲的情況

第一步：找到com.zxing.camera包下的CameraConfigurationManager.java文件中的void initFromCameraParameters(Camera camera)方法

第二步：在 Log.d(TAG, Screen resolution: + screenResolution);後加上如下的代碼

Point screenResolutionForCamera = new Point();
screenResolutionForCamera.x = screenResolution.x;
screenResolutionForCamera.y = screenResolution.y;
// preview size is always something like 480*320, other 320*480
if (screenResolution.x < screenResolution.y) {
    screenResolutionForCamera.x = screenResolution.y;
    screenResolutionForCamera.y = screenResolution.x;
}

第三步：替換screenResolution為screenResolutionForCamera

cameraResolution = getCameraResolution(parameters, screenResolution);  

找到上邊的代碼替換成下邊的代碼(如下圖)

cameraResolution = getCameraResolution(parameters, screenResolutionForCamera);
