The default is portrait scanning, but when we configure the horizontal screen display in the manifest file:

  <activity            android:name=". Captureactivity"            android:screenorientation="landscape"             android:theme="@android: Style/theme.notitlebar.fullscreen" / >

This time scan, you will find that the scanning effect deformation, the direction is wrong.

You can modify it by following these steps:

1, modify the setdesiredcameraparameters function in Cameraconfigurationmanager.java ,

Camera.setdisplayorientation (90); ---> camera.setdisplayorientation (0);

2. Modify Cameramanager.java 's getframingrectinpreview () function to change to the following, change x to Y, y to X

Rect.left = Rect.left * cameraresolution.x/ screenresolution.x;   = Rect.right * cameraresolution.x/  screenresolution.x;   = Rect.top * CAMERARESOLUTION.Y/ screenresolution.y;   = Rect.bottom * CAMERARESOLUTION.Y/  screenresolution.y;  

3, modify the decode function in Decodehandler.java

4. Other modifiable parts refer to GitHub Demo
