我拿着相机摄像头方向面临的问题的工作。我通过互联网找到了一些答案，我认为这个答案可能最适合我。Android摄像头方向为新手

任何人都可以给我详细的指令，how to add this answer在我的相机项目？

直接代码在这里

为了解决您的相机的方向改变了你的surfaceCreated功能，从风景模式默认的Android相机默认波泰特模式旋转摄像头（因为您的活动处于肖像模式）：

@Override 
public void surfaceCreated(SurfaceHolder holder) { 
    camera = Camera.open(); 
    Parameters parameters = camera.getParameters(); 
    camera.setDisplayOrientation(90); 
    camera.setParameters(parameters); 
}

您的a PP也崩溃，当您尝试并拍照......但就是手头没有问题......尽管它可能有你需要将下面的行添加到您的清单做：

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
