Android Direction sensor sensor.type_orientation after abandonment get direction information

Android Direction sensor Sensor.type_orientation has been in the wirelessly is not recommended to use, with getorientation to replace, with this but not as before, you can get the data, need to use both geomagnetic sensors and accelerometer to obtain, the code is as follows:

Layout file has only one TextView
