Android 判断手机是否有传感器

自己想做个计步器的Demo  找了些资料mark一下

/**
* 判断该设备是否支持计歩
*
* @param context
* @return
*/
@TargetApi(Build.VERSION_CODES.KITKAT)
public static boolean isSupportStepCountSensor(Context context) {
// 获取传感器管理器的实例
SensorManager sensorManager = (SensorManager) context
.getSystemService(context.SENSOR_SERVICE);
Sensor countSensor = sensorManager.getDefaultSensor(Sensor.TYPE_STEP_COUNTER);
Sensor detectorSensor = sensorManager.getDefaultSensor(Sensor.TYPE_STEP_DETECTOR);
return countSensor != null || detectorSensor != null;
}
