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 canceled and developers need to use SensorManager.

Some time ago, a netizen sent a private message to me (@ Wu Ge) and asked me if I had done magnetic field sensors and could I have done compass? As I have already said in the first section, the magnetic field sensor can be used, but the algorithm is troublesome. The simplest compass can be made using a direction sensor

The following are all converted from the android game programming entry-level classic. For more information, see the source. An interesting input method in the game is the accelerator. All Android devices require a 3D accelerator. Also, the compass function can sense the magnetic field direction and the mobile phone pi

As mentioned above, the first parameter value passed back by the horizontal sensor represents the angle from which the mobile phone rotates around the Z axis, that is, the angle between the top of the mobile phone and the north. In the program, you can check the angle to implement the compass application. In fact, the idea is very simple. First prepare an image, which directs the pointer to the north. Then, a sensor is developed to detect the directio

The latest version of the SDK adds the phrase "type_orientation this constant is deprecated. Use Sensormanager.getorientation () instead. This means that the method has been canceled, and the developer uses sensormanager.getorientation () to get the original data.In fact, the Android get direction is obtained by the magnetic field sensor and the accelerometer sensor, as for the specific algorithm SDK has be

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:

As mentioned above, the first parameter value passed back by the horizontal sensor represents the angle from which the mobile phone rotates around the Z axis, that is, the angle between the top of the mobile phone and the north.

In some of the previous blogs about Android, there are articles about custom controls. So, in this blog post, I'll show you how to implement the Compass view in a way that customizes the control. We will create a new compass view by extending the view class. It indicates the direction of the current orientation by displaying the traditional compass.First, realize

The compass has always been an indispensable and important role. The idea of developing a compass is very simple. The program first prepares a picture of the compass so that the pointer on the picture points to the north, and then develops the sensor in the detection direction, the program detects the number of degrees at the top of the phone that bypasses the ZF

Simple tutorial for Android-46th guns (a compass for custom controls)Preface As an innovative developer, you will sooner or later find that the built-in controls cannot satisfy your imagination. With the ability to expand existing views, build composite controls, and create unique new views, you can create a beautiful user interface that best suits your application workflow, this gives users the best experi

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 directly get the direction of the device, but the latest version of the SDK plus such a sente

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 used in it is a temporary PPT. It is very simple

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 =
