compass for mongodb

Based on the online materials, I made a compass app. Steps: 1. Obtain SensorManager. MSensorManager = (SensorManager) getSystemService (SENSOR_SERVICE ); 2. register the listener 3. Listener implementation SensorEventListener mSensorEventListener = degree = event. values [0 transit ra = Merge (currentDegree,-0.5f0.5f ra. setDuration (200 ra. setFillAfter (=-onAccuracyChanged (Sensor sensor, 4. release resources and cancel listener Regis

found this problem, but I don't know if you have noticed it. When the blog seeds were burned with feedsky, I found that, this post has already been posted on the clearly-posted blog page.ArticleAfter an hour or two, you can directly access the feedsky seeds without displaying this article.It seems that feedsky sometimes has a certain lag problem, especially at midnight, is it because feedsky crawler automatically reduces the detection frequency because of low writing frequency?Let's take a look

This article examples for you to explain how to easily achieve the Android Compass function, share for everyone to reference. Specifically as follows: (1) The layout file is as follows: Picture required: (2) 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.SensorM

In this article, we use fireworks 8来 to draw an exquisite compass pattern. The completed results are as follows: (Figure 01) First, set the canvas size to 128x128 pixels and the background to white. (Figure 01) Draw a 90x90 circle with an elliptical tool and align it horizontally and vertically to the canvas; (Figure 02) (Figure 02) Change the fill category to a linear gradient, and increase and adjust the gradient color; (Figure 03)
