Android enables mobile phone orientation recognition

//自定义导航图标private BitmapDescriptor mIconLocation;//自定义传感器implements SensorEventListenerprivate MyOrientationListener myOrientationListener;//把监听的x方向的值存储到这里private float mCurrentX;

 //initialize icon  miconlocation = Bit        Mapdescriptorfactory.fromresource (R.drawable.ic_launcher); //Initialize callback interface  Myorientationlistener = new  myorient        Ationlistener (Getapplicationcontext ()); //Set callback interface  Myorientationlistener.setonorientationlistener (new  Onorientationlistener () { @Override  public  void    Onorientationchanged  (float  x) {//TODO auto-generated method stub  //callback interface value stored in Mcurrentx  mCu            Rrentx=x; }        });

Synchronization with the life cycle of direction recognition within the activity lifecycle

Start method inside

    //方向识别开始        myOrientationListener.start();      

Stop method inside

//停止方向传感器        myOrientationListener.stop();

Inside the local Data settings

    MyLocationData data = new MyLocationData.Builder()    //设置方向    .direction(mCurrentX)//设置自定义图标        MyLocationConfiguration config = new MyLocationConfiguration(com.baidu.mapapi.map.MyLocationConfiguration.LocationMode.NORMAL,                         true, mIconLocation);                mBaiduMap.setMyLocationConfigeration(config);

Here is the implementation code for sensor monitoring

 Public  class Myorientationlistener implements Sensoreventlistener{    //used to get Seosor    PrivateSensormanager Msensormanager;PrivateSensor Msensor;PrivateContext Mcontext;Private floatLASTX;PrivateOnorientationlistener Monorientationlistener; Public Myorientationlistener(Context context) {Super(); context= This. Mcontext; }@SuppressWarnings("Deprecation")//How to turn on monitoring     Public void Start() {Msensormanager = (Sensormanager) mcontext.getsystemservice (Context.sensor_service);if(msensormanager!=NULL) {msensor = Msensormanager.getdefaultsensor (sensormanager.sensor_orientation); }if(msensor!=NULL){//Register for monitoringMsensormanager.registerlistener ( This, Msensor, sensormanager.sensor_delay_ui); }    }//How to stop listening     Public void Stop() {Msensormanager.unregisterlistener ( This); }@Override     Public void onaccuracychanged(Sensor arg0,intARG1) {}@Override     Public void onsensorchanged(Sensorevent event) {//Get direction sensor if (Event.sensor.getType () ==sensor.type_orientation) {            floatx = event.values[sensormanager.data_x];//If moving more than one precision then turn            if(Math.Abs (X-LASTX) >1.0){if(monorientationlistener!=NULL) {monorientationlistener.onorientationchanged (x);        }} LASTX =x; }           } Public void Setonorientationlistener(Onorientationlistener Monorientationlistener) { This. Monorientationlistener = Monorientationlistener; }//Define Callback interface     Public  interface onorientationlistener{    //Pass change in the X-direction value of the listener        voidOnorientationchanged (floatx); }}
