我一直遵守以下的答案做到这一点。http://stackoverflow.com/a/16252917/2747591

但我没有得到我想要做的。

由于相机拍摄的图像是通过90度，而我试图扫描旋转。就像如果你使用的是相机，那么在我的手机屏幕是显示90度旋转的preVIEW点击一个人的照片。但是，这不是我想要的，因为它正在酒吧code扫描难以使用。我想preVIEW理所应当的。任何想法？

下面是我在code更改

第1步

在德codeHandler.java我加入以下code只是buildLuminanceSource之前

 字节[] = rotatedData新的字节[data.length]对于（INT Y = 0; Y＆LT;高度; Y ++）{    对于（INT X = 0; X＆LT;宽度; X ++）        rotatedData [X *高+高 -  Y  -  1] =数据[X + Y *宽]}INT TMP =宽度; //这里，我们交换，这就是区别，以＃11宽度=高度;HEIGHT = tmp目录;数据= rotatedData;PlanarYUVLuminanceSource源= activity.getCameraManager（）buildLuminanceSource（数据，宽，高）。 

第2步

修改getFramingRectIn $ P $在CameraManager.java PVIEW（）

  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; 

第3步

禁用风景模式initFromCameraParameters在CameraConfigurationManager.java检查（...）

的说明是删除

 如果（宽度LT;高度）{  Log.i（TAG，报告显示纵向;假设这是不正确）;  INT TEMP =宽度;  宽度=高度;  高度=温度;} 

但我没有找到我的Cameraconfiguration这个文件code。因此它不应该反正无所谓

第四步

添加以下行只是定义参数应用后旋转CameraConfigurationManager.java相机setDesiredCameraParameters（...）

  camera.setDisplayOrientation（90）; 

第5步

从变更景观CaptureActivity方向为纵向像这样我的应用程序的清单文件

 ＆LT;活动           机器人：名字=com.google.zxing.client.android.CaptureActivity           机器人：screenOrientation =画像           机器人：configChanges =方向| keyboardHidden           机器人：主题=@安卓风格/ Theme.NoTitleBar.Fullscreen           机器人：windowSoftInputMode =stateAlwaysHidden＆GT;           ＆所述;意图滤光器＆gt;              ＆lt;作用机器人：名字=android.intent.action.MAIN/＆GT;              ＆LT;类机器人：名字=android.intent.category.DEFAULT/＆GT;           ＆所述; /意图滤光器＆gt;           ＆所述;意图滤光器＆gt;              ＆lt;作用机器人：名字=com.google.zxing.client.android.SCAN/＆GT;              ＆LT;类机器人：名字=android.intent.category.DEFAULT/＆GT;           ＆所述; /意图滤光器＆gt;    ＆LT; /活性GT; 

解决方案

我用zxing zxing 2.3及以下的解决方案，为我工作。

1在CameraConfigurationManager类，setDesiredCameraParameters方法下面添加下面尖线code

- > Camera.Parameters参数= camera.getParameters（）;

 如果（context.getResources（）。getConfiguration（）。方向== Configuration.ORIENTATION_PORTRAIT）{        camera.setDisplayOrientation（90）; } 

2在CameraManager类，getFramingRect方法代替code如下

  INT宽度= MIN_FRAME_WIDTH; INT高度= MIN_FRAME_HEIGHT;如果（context.getResources（）。getConfiguration（）。方向== Configuration.ORIENTATION_PORTRAIT）{   INT TMP = 7 * screenResolution.x / 8;   宽度=（TMP）LT; MIN_FRAME_WIDTH？ MIN_FRAME_WIDTH：（TMP）;   TMP = 1 * screenResolution.y / 3;   身高=（TMP）LT; MIN_FRAME_WIDTH？ MIN_FRAME_WIDTH：（？（TMP）＆GT; MAX_FRAME_HEIGHT MAX_FRAME_HEIGHT：（TMP））;}其他{   //原始code   宽度= findDesiredDimensionInRange（screenResolution.x，MIN_FRAME_WIDTH，＆GT; MAX_FRAME_WIDTH）;   身高= findDesiredDimensionInRange（screenResolution.y，MIN_FRAME_HEIGHT，MAX_FRAME_HEIGHT）;} 

3在CameraManager类，getFramingRectIn preVIEW方法代替code如下

 如果（context.getResources（）。getConfiguration（）。方向== Configuration.ORIENTATION_PORTRAIT）{   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;}其他{   //原始code评论   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;} 

4在德$ C $钱德勒类，德code方法下面添加code以下尖头行

- >结果rawResult = NULL;

 如果（activity.getResources（）。getConfiguration（）。方向== Configuration.ORIENTATION_PORTRAIT）{        字节[] = rotatedData新的字节[data.length]        对于（INT Y = 0; Y＆LT;高度; Y ++）{            对于（INT X = 0; X＆LT;宽度; X ++）                rotatedData [X *高+高 -  Y  -  1] =数据[X + Y *宽]        }        数据= rotatedData;        INT TMP =宽度;        宽度=高度;        HEIGHT = tmp目录;  }

I have followed the following answer to do this. http://stackoverflow.com/a/16252917/2747591

But I am not getting what i want to do.

The image captured by camera is rotated by 90 degree while i am trying to scan. Like if you are clicking a photo of a person using the camera, then in my phone screen it is showing the preview rotated by 90 degree. But that is not what i want as it is making bar code scanning difficult to use. I want preview as it should be. Any ideas?

Here are my changes in the code

Step 1

In DecodeHandler.java I have added the following code just before buildLuminanceSource

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;
data = rotatedData;
PlanarYUVLuminanceSource source = activity.getCameraManager().buildLuminanceSource(data, width, height);

Step 2

Modified getFramingRectInPreview() in CameraManager.java

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;

Step 3:

Disable the check for Landscape Mode in initFromCameraParameters(...) in CameraConfigurationManager.java

The instructions is to Remove

if (width < height) {
  Log.i(TAG, "Display reports portrait orientation; assuming this is incorrect");
  int temp = width;
  width = height;
  height = temp;
}

But I didn't find this code in my Cameraconfiguration file. so it should not matter anyways

Step 4

Added following line to rotate camera in setDesiredCameraParameters(...) in CameraConfigurationManager.java just after defining parametres

camera.setDisplayOrientation(90);

Step 5

Changed the CaptureActivity orientation from landscape to portrait in my app's manifest file like this

<activity
           android:name="com.google.zxing.client.android.CaptureActivity"
           android:screenOrientation="portrait"
           android:configChanges="orientation|keyboardHidden"
           android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
           android:windowSoftInputMode="stateAlwaysHidden">
           <intent-filter>
              <action android:name="android.intent.action.MAIN"/>
              <category android:name="android.intent.category.DEFAULT"/>
           </intent-filter>
           <intent-filter>
              <action android:name="com.google.zxing.client.android.SCAN"/>
              <category android:name="android.intent.category.DEFAULT"/>
           </intent-filter>
    </activity>

I have used zxing zxing 2.3 and below solution worked for me.

1 In CameraConfigurationManager class, setDesiredCameraParameters Method add below code below pointed line

-> Camera.Parameters parameters = camera.getParameters();

 if (context.getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT) {
        camera.setDisplayOrientation(90);
 }

2 In CameraManager class, getFramingRect Method replace code as below

int width = MIN_FRAME_WIDTH; int height = MIN_FRAME_HEIGHT;
if (context.getResources().getConfiguration().orientation ==Configuration.ORIENTATION_PORTRAIT) {
   int tmp = 7 * screenResolution.x / 8; 
   width = (tmp) < MIN_FRAME_WIDTH ? MIN_FRAME_WIDTH : (tmp);                   
   tmp = 1 * screenResolution.y / 3;
   height = (tmp) < MIN_FRAME_WIDTH ? MIN_FRAME_WIDTH : ((tmp) > MAX_FRAME_HEIGHT ?  MAX_FRAME_HEIGHT : (tmp));
}else{
   // Original Code
   width = findDesiredDimensionInRange(screenResolution.x, MIN_FRAME_WIDTH, > MAX_FRAME_WIDTH);
   height = findDesiredDimensionInRange(screenResolution.y, MIN_FRAME_HEIGHT,  MAX_FRAME_HEIGHT); 
}

3 In CameraManager class, getFramingRectInPreview Method replace code as below

if (context.getResources().getConfiguration().orientation ==Configuration.ORIENTATION_PORTRAIT) {
   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;
}else{
   // Original code commented
   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;
}

4 In DecodeHandler class, decode Method add below code below pointed line

-> Result rawResult = null;

 if (activity.getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT){
        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];
        }
        data = rotatedData;
        int tmp = width;
        width = height;
        height = tmp;

  }
