請別人幫我。我試圖將http://drobosson.blogspot.com/2011/01/google-android-camera-preview-data.htmlhttp://marakana.com/forums/android/examples/39.html轉換爲Monodroid(C#),但都沒有成功。我遵循指示(據我所知),我不知道如何預覽相機(我甚至沒有拍攝PICTURE)。Monodroid相機+預覽

這裏是我當前的代碼 - 它失敗的Android.Hardware.Camera.Open()方法有了java.lang.RuntimeException(堆棧跟蹤說「在Android.Runtime.JNIEnv.CallStaticObjectMethod(IntPtr的JCLASS,IntPtr的jmethod)[0x00000] in:0 at Android.Hardware.Camera.Open()...「)

我已經在清單中添加了相機權限。

代碼:

protected override void OnCreate(Bundle bundle) 
    { 
     base.OnCreate(bundle); 

     SetContentView(Resource.Layout.CameraPage); 

     _surfaceView = FindViewById<SurfaceView>(Resource.Id.imgCapture); 
     _debug = FindViewById<TextView>(Resource.Id.lblCameraDebug); 

     try 
     { 
      _camera = Android.Hardware.Camera.Open(); 
      //Android.Hardware.Camera.Parameters camparam = _camera.GetParameters(); 
      //camparam.SetPreviewSize(_surfaceView.Width, _surfaceView.Height); 
      //_camera.SetParameters(camparam); 

      //_camera.SetPreviewDisplay(_surfaceView.Holder); 
      //_camera.StartPreview(); 
     } 
     catch(Exception ex) 
     { 
      _debug.Text = string.Format("Error: {0} - StackTrace: {1}", ex.Message,ex.StackTrace); 
     } 
    }
