我的问题是,在默认情况下,相机是在横向模式,我不能改变这个原因,我需要定义CameraBridgeViewBase而不是一般的相机意图.

这是我的代码的一部分：

XML代码：

<LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent" >
 
            <org.opencv.android.JavaCameraView
                android:layout_width="fill_parent"
                android:layout_height="300dp"
                android:visibility="gone"
                android:id="@+id/HelloOpenCvView"
                opencv:show_fps="true"
                opencv:camera_id="1" />
 
 
        </LinearLayout>  
 
        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content" >
 
 
            <Button
                android:id="@+id/BtnVideo"
                android:layout_marginLeft="2dp"
                android:layout_marginRight="2dp"                    
                android:layout_width="0dp"
                style="@style/button"
                android:layout_height="wrap_content"
                android:layout_weight="1.00"
                android:text="@string/videoBtn"
                android:textSize="18dip" />
 
 
        </LinearLayout>

Java代码：

CameraBridgeViewBase mOpenCvCameraView;
    Button VideoButton;
 protected void onCreate(Bundle savedInstanceState) {
 
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        overridePendingTransition(0,0);
 
        VideoButton = (Button) this.findViewById(R.id.BtnVideo);
 
        VideoButton.setOnClickListener(onClickListener);
 
        mOpenCvCameraView= (CameraBridgeViewBase) findViewById(R.id.HelloOpenCvView);
        mOpenCvCameraView.setVisibility(SurfaceView.INVISIBLE);
 
    } 
 
        private OnClickListener onClickListener = new OnClickListener() {
 
            @Override
            public void onClick(View v) {
                    switch (v.getId()){
 
                        case R.id.BtnVideo:
                            if(mOpenCvCameraView.getVisibility() == SurfaceView.VISIBLE)
                            {
                                mOpenCvCameraView.setVisibility(SurfaceView.INVISIBLE);
                            }
                            else
                            {
                                mOpenCvCameraView.setVisibility(SurfaceView.VISIBLE);
                            }
 
                            break;
                        default :
                            break;
                    }
 
            }
        };
 
 
        public void onResume() {
            super.onResume();
            overridePendingTransition(0,0);
            OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION_2_4_3,this,mLoaderCallback);
        }
         public void onPause()
         {
             super.onPause();
             if (mOpenCvCameraView != null)
                 mOpenCvCameraView.disableView();
         }
         public void onDestroy() {
             super.onDestroy();
             if (mOpenCvCameraView != null)
                 mOpenCvCameraView.disableView();
         }
         public void onCameraViewStarted(int width,int height) {
         }
 
         public void onCameraViewStopped() {
         }
         public Mat onCameraFrame(CvCameraViewFrame inputFrame) {
             return inputFrame.rgba();
         }
 
        private BaseLoaderCallback mLoaderCallback = new BaseLoaderCallback(this) {
            @Override
            public void onManagerConnected(int status) {
                switch (status) {
                    case LoaderCallbackInterface.SUCCESS:
                    {
                        //Log.i(TAG,"OpenCV loaded successfully");
                        mOpenCvCameraView.enableView();
                    } break;
                    default:
                    {
                        super.onManagerConnected(status);
                    } break;
                }
            }
        };

那么如何更改默认方向？

谢谢！
