magnetic compass sensor

This article illustrates how Android uses the sensor sensor to get the direction of a user's movement. Share to everyone for your reference, specific as follows: Today continue to share a second important sensor, in fact, to get the direction of the things should be very simple, in the previous article to see that there is a type_orientation keyword, you can dir

involves three concepts:Roll: left and right tilt angle, also called Rolling Angle http://baike.baidu.com/view/1769672.htmPitch: front and back tilt, also called the pitch angle http://baike.baidu.com/view/3832041.htmYaw: Left and Right swing, also called yaw angle http://baike.baidu.com/view/1769448.htm The following code is the source code of/development/samples/compass in android2.3. It demonstrates how to determine the placement posture and orien

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:

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

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

measurement mode, single measurement I used a bit, not very good, so the following main introduction of continuous measurement. Configuration as a continuous measurement is simple, is the above mode register, address 0x02 As you can see, configuring a continuous measurement mode requires only writing the mode register to 0x00. Configuration to continuous, configured as sequential read mode there is a very important place to remember: read XYZ, must read 6 bytes at a time, that is, all r

Because the real machine is rotten, after acquiring all the available sensors there is no direction sensor and no magnetic field sensor, so it was aborted and therefore not fully developed, but according to some things in the document added the process of using sensor,First set up a getter in CustomView, which is to ge

Step 1: Create a new project compass and import a compass picture into the res/drawable-hdpi directory Step 2: Design the UI interface for the application, Main.xml Step 3:mainactivity.java Import android.app.Activity; Import Android.content.Context; Import Android.hardware.Sensor; Import android.hardware.SensorEvent; Import Android.hardware.SensorEventListener; Import Android.hardware.Se

I just followed the video to learn the operation examples of sensors in Android, and made a very simple compass application using the direction sensor... Sensor functions are rarely used in work projects, so many of them don't know. Now I want to learn more about it as a step-by-step approach... First paste the software for final operation The image material use

Step 1:Create a new project Compass and import a Compass image to the res/drawable-hdpi directory. Step 2:Design the application UI, main. xml Copy codeThe Code is as follows: Android: orientation = "vertical" Android: layout_width = "fill_parent" Android: layout_height = "fill_parent" Android: gravity = "center" > Android: layout_width = "wrap_content" Android: layout_height = "wrap_content" Android: src
