Rotate to the left and negative on they axis. Rotates to the right and they -axis is positive. Rotate up and thex axis is negative. Rotate downward and thex axis is positive. ST 's l3g series of gyroscope sensors are more popular,iphone4 and Google 's Nexus S used in this type of
Android practice simple tutorial-62nd guns (electronic Sensor exact Compass)
Here we use the sensor provided by the mobile phone to implement a simple small example of the electronic compass. You can learn how to use the SensorManager class, SensorEventListener and its overwriting method.
First, create a layout file:
Then the Activity file:
Let's take a look at the sensormanager code.

1. Sensor Type
Android has a variety of sensors. Currently, Android SDK supports light sensors, rotating vector sensor
Motion sensors are useful for monitoring the movement of devices, such as tilt, vibration, rotation, and swing, which are the monitoring ranges of motion sensors. The movement of a device is usually a direct response to user input.All motion sensors return a value of three floating-point numbers, and for different sensors, the three values have different meanings. For example, for an accelerometer, the acceleration data for three axes is returned. For a gyro
. Which sensors are provided in Android:
1. Acceleration Sensor (gravity sensor)
2. gyroscope Sensor
3. Optical Sensors
5. Constant Magnetic Field Sensor
6. Direction Sensor
7. Constant
Sensor overviewSensors are one of the important symbols of the second generation of smartphones. Many phones and tablets are now built-in with sensors (except TV). The Android SDK supports a number of more than 10 sensors, but the phone only supports a subset. such as the direction sensor (electronic compass) and the gravity
This article translated from: http://developer.android.com/guide/topics/sensors/sensors_overview.html
Most Android devices have built-in sensors for measuring motion, direction, and various environmental conditions. These sensors provide raw data with high precision and accuracy that can be used to monitor the movement and position of a device in three dimensions, or to monitor changes in the environment around the device. For example, a game may hav
Good evening ~ Today, I will continue to share with you the second important sensor. In fact, it is very easy to get the direction.ArticleA type_orientation keyword indicates that the device's moving direction can be directly obtained. However, the latest SDK adds the phrase "type_orientation this constant is deprecated. use sensormanager. getorientation () instead. that is to say, this method has been canceled and developers need to use sensormanager
With a wide range of sensors in Android development, Google offers 11 sensors for use in layers: acceleration, magnetism, direction, gyroscope, light, pressure (back to current pressure), temperature, proximity (detecting distance between objects and phones), gravity, linear acceleration, and rotational vectors.Before using the sensor, the class interface in the
Good evening ~ Today, I will continue to share with you the second important sensor. In fact, it is very easy to get the direction. In the first article, we will see a TYPE_ORIENTATION keyword, indicating that we can directly get the device's direction of movement, however, the latest SDK adds the following sentence: "TYPE_ORIENTATION This constant is deprecated. use SensorManager. getOrientation () instead. that is to say, this method has been cancel
As an input device of the Android system, sensor is essential for Android devices. Sensor mainly reports G-sensor, lightssensor, proximitysensor, and temperaturesensor. The porting of each sensor is similar. This article describes
Once upon a time, I wrote an article on Android sensor "stunning entire basketball court "... in a twinkling of an eye, two years have passed. It's really a thing that's gone, and the technology is updated fast. Now it's 4.0 chocolate ice cream...
