无法访问片段内的SENSOR_SERVICE

Question

这曾经像

sSensorManager = (SensorManager)this.getSystemService(SENSOR_SERVICE);

在一项活动中，现在是片段我正在制作如下

sSensorManager = (SensorManager)rootView.getContext().getSystemService(SENSOR_SERVICE);

然后我在SENSOR_SERVICE下方获得红线，如下所示

SENSOR_SERVICE cannot be resolved to a variable

Answer 1

在Fragment

中试试

sSensorManager = (SensorManager)getActivity().getSystemService(getActivity().SENSOR_SERVICE);

Answer 2

无论您身在何处，都可以像static Constant

那样访问

sSensorManager = (SensorManager)rootView.getContext().getSystemService(Context.SENSOR_SERVICE);
