最近两天一直在看android相机的参数设置，Camera.Parameters中属性值非常的多，我索性就把就调用的flatten()方法，将设置的参数值都打印出来了，方便以后查看，如果想要修改那个属性，使用set方法，比如设置缩放
if(parameters.isZoomSupported()){
//tenDesiredZoom取值在parameters.getMinZoom()与parameters.getMaxZoom()之间
parameters.set("zoom", String.valueOf(tenDesiredZoom));
}
想要获取设置的属性值就更简单了，直接调用下面的方法就搞定了：
parameters.get(String key);下面列表中，等号前面的就是key值，后面就是对应属性值value：
