@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);
