我正在尝试使用Camera API为三星Galaxy S5设置ISO。 包含相机参数中ISO标记的参数（使用camera.getParameters.flatten（）;进行检索）是：
我认为exif_iso参数与Meta文件有关，所以我不需要它。 iso设置是我需要的，我可以选择iso值下的所有值。如果我设置其中一个参数，则接受参数（不会抛出任何异常）。如果我使用未在值下声明的参数，则抛出异常。所以iso的值已经设定好了！
但是......奇怪的是，当你拍照时，iso设置似乎被忽略了。白平衡和分辨率等设置就像魅力一样，但我不能让iso改变。在另一部手机（星系S2）上，iso设置确实有效。
在三星的官方相机应用程序中，iso值是可编辑的，所以在api的某个地方应该是可能的！我已经尝试了一些来自游戏商店的相机应用程序（包括开放式相机1.20），但同样的事情;你可以改变它，但它会被忽略。
有谁知道为什么价值被忽略了？是否有其他参数可以启用或禁用此类设置？
非常感谢：）
更新 我更进一步了。它似乎是由我在我的应用程序中使用的OpenCV引起的。特别是类CameraBridgeViewBase似乎导致iso设置问题。即使我在拍照前禁用了视图，iso设置也会被忽略。我在没有使用OpenCV的情况下构建了一个小型相机应用程序，而iso设置就像它应该的那样。
如果使用CameraBridgeViewBase的应用程序正在运行（即使您之后清除了内存），我的相机测试应用程序iso设置将再次被忽略。我也尝试了应用程序'打开相机'，iso设置再次被忽略。如果我启动官方三星相机应用程序，它似乎重置整个相机;之后我的相机测试应用程序和'打开相机'iso设置再次工作。
奇怪的是，我的三星Galaxy S2上根本没有出现这个问题。它只发生在三星Galaxy S5上......
CameraBridgeViewBase：OpenCV类，用于从相机捕获（视频）帧，显示它并实现'onFrameListener'功能。
