推荐答案

如果您需要简单的过滤器(如棕褐色或负片)，则可以通过CaptureRequest.Builder方法在CaptureRequest实例中设置CONTROL_EFFECT_MODE字段 mBuilder.set(CaptureRequest.CONTROL_EFFECT_MODE，/*您的值*/);

If you need simple filters like sepia or negative you can just set CONTROL_EFFECT_MODE field in CaptureRequest instance via CaptureRequest.Builder method mBuilder.set(CaptureRequest.CONTROL_EFFECT_MODE, /*your value*/);

请参见开发者文档可用值.
