lesson 137 sensors
00:00:18
in this lesson we read sensor data I
00:00:20
will try to state what I understood from everything
00:00:22
I read on sensors
00:00:24
we will consider how you can get data from
00:00:26
sensors and how this data can be
00:00:28
used android supports
00:00:30
several types of sensors at the moment
00:00:32
cold reports that there are 13 such types we are in
00:00:35
this In this lesson we will look at the light sensors of the
00:00:37
acceleration of gravity and the magnetic field.
00:00:39
Receiving sensor data is not difficult; for
00:00:42
this we will need to request a
00:00:44
sensor object from the system and attach a listener to it. The
00:00:46
listener method will
00:00:48
receive an array with data. The first
00:00:50
application will show us a list of
00:00:52
available sensors and data from the
00:00:54
light sensor. let's create a project
00:00:59
string sex
00:01:00
add strings
00:01:07
screen main.xml
00:01:15
buttons to get a list of sensors and
00:01:17
light data and a textview to
00:01:19
display the data
00:01:25
we in activity
00:01:33
oncreate get sens
00:01:35
and ask it for a complete list of
00:01:37
sensors using the get sensor list method
00:01:40
and passing the sensor type type of there
00:01:43
to get a specific sensor,
00:01:45
call the get method default senso, pass
00:01:48
it type light and get the light sensor
00:01:50
here more carefully, because if there is
00:01:52
no such sensor in the device, then the method will return, well,
00:01:55
there’s a clixsense list, we unsubscribe
00:01:58
the listener from the sensors, about this a little
00:02:00
later, then we take the list of sensors and
00:02:03
display them info on the screen get name
00:02:05
name gettype type get vendor creator get
00:02:09
vertices version get maximum range the
00:02:12
maximum value that can be
00:02:14
returned by senso guitars solution as far as
00:02:16
I understand this is the minimum step with which the
00:02:18
value can be measured
00:02:22
in the onclick sense light method we
00:02:24
use the killing method in the forest so that
00:02:27
on earlier the received light sensor
00:02:29
hang up its listener listen live the
00:02:31
third parameter of the method is the speed of
00:02:34
receiving new data, that is, how
00:02:35
often do we need to receive data from the
00:02:38
sensor there are four speeds in descending order
00:02:41
the truth hell writes that the system can
00:02:43
ignore this value and produce
00:02:46
data that is convenient and starting with and saw
00:02:49
vol 9, instead of a speed constant, you can
00:02:51
transmit your microsecond value,
00:02:54
don’t confuse it with seconds, it has stripes,
00:02:57
we describe our adsense listeners
00:02:59
of dawn here, as usual, it is recommended to
00:03:01
unsubscribe as soon as you don’t need the data so
00:03:03
as not to waste the battery
00:03:06
lesnar light listener implements the
00:03:08
sensor interface Ivan moldy it has two
00:03:11
methods 1 is called when the
00:03:14
accuracy of the sensor data changes and at the beginning of
00:03:16
receiving data gives us the sensor object
00:03:18
and the level of accuracy maximum possible
00:03:22
accuracy average accuracy calibration
00:03:24
could improve the result low
00:03:26
accuracy calibration required
00:03:29
sensor data nothing at all needed either
00:03:31
calibration or it is impossible to read the data
00:03:33
it is a sensor than here we receive data
00:03:37
from the sensor in the sensor event object,
00:03:39
save everything and launch the application and
00:03:41
click on the sheet and get a list. For me it
00:03:44
looks like this. On the screen you can see that
00:03:46
the device has several sensors of the
00:03:47
same type,
00:03:48
if instead of that gender you pass
00:03:51
some kind of sensor sheet to the get method specific type of
00:03:53
sensor, then we will get a list of sensors of
00:03:55
only this type, now press light,
00:03:58
the application will show the current
00:04:00
illumination value, try changing the brightness,
00:04:02
the lighting next to the device should
00:04:04
change the value, in my dimly lit
00:04:07
room it shows 0, if you take a flashlight
00:04:09
from afar, start bringing it to the light sensor,
00:04:11
it will show sequentially 10100 1000
00:04:15
10000 and at the end of 30 thousand, while on
00:04:18
the screen with the list of sensors you can see that the
00:04:20
maximum value is 3000 and the step
00:04:23
if I understood the parameters correctly
00:04:26
solution 1 why there is such a discrepancy between the
00:04:28
information and reality I don’t know, continuation
00:04:31
in the next lesson

В этом уроке: читаем данные с сенсоров в андроид устройствах, я попробую изложить то, что я понял из всего мною прочитанного по сенсорам. Рассмотрим, как можно получить данные от сенсоров и как эти данные можно использовать. Android поддерживает несколько типов сенсоров. В данный момент хелп сообщает, что таких типов 13. Мы в этом уроке рассмотрим сенсоры света, ускорения, гравитации и магнитного поля. Получать данные с сенсоров несложно. Для этого нам надо будет запросить у системы объект-сенсор и повесить на него своего слушателя. В метод слушателя будет приходить массив с данными.
