@Override

  Camera camera = new Camera();
  camera.save();

  // 设置camera动作为绕Y轴旋转
  // 总共旋转180度，因此计算在每个补间时间点interpolatedTime的角度即为两着相乘
//    camera.rotateX(deg * interpolatedTime);
  camera.rotateY(180 * interpolatedTime);
//    camera.rotateZ(180 * interpolatedTime);
//
  // 根据camera动作产生一个matrix，赋给Transformation的matrix，以用来设置动画效果
  Matrix matrix = t.getMatrix();
  camera.getMatrix(matrix);

  camera.restore();
  //经过以下平移，才能以view的中心点进行翻转
  matrix.preTranslate(-view.getWidth() / 2, -view.getHeight() / 2);
  matrix.postTranslate(view.getWidth() / 2, view.getHeight() / 2);
 }
