          camera = Camera.open();         Camera.Parameters params = camera.getParameters();         params.setPreviewSize(800,480);         params.setPreviewFpsRange(5,5);         params.setPictureSize(2014,768);         params.setJpegQuality(80);         camera.setParameters(params);         try {
              camera.setPreviewDisplay(surfaceHolder);             camera.startPreview();//开始预览         } catch (IOException e) {
              e.printStackTrace();         }     }     @Override     public void surfaceChanged(SurfaceHolder surfaceHolder, int i, int i1, int i2) {
      }     @Override     public void surfaceDestroyed(SurfaceHolder surfaceHolder) {
          if(camera!=null){
              camera.release();         }     } }
