1、android有关sensor的源码总结   虽然这篇文章写得很差，因为赶时间，所以就匆匆忙忙地写出来自己作一个笔记。但是我想对大家应该有一点帮助。1、有关sensor在Java应用程序的编程（以注册多个传感器为例，这程序是我临时弄出来的，可能有错）packagecom.sensors.acc;importandroid.app.Activity;importandroid.os.Bundle; importandroid.util.Log;importandroid.widget.TextView;importandroid.hardware.Sensor

2、Manager;importandroid.hardware.Sensor;importandroid.hardware.SensorEvent;importandroid.hardware.SensorEventListener; publicclassaccextendsActivity{   floatx,y,z;   SensorManagersensormanager=null;   SensoraccSensor=null;   SensorlightSensor=null;   SensorproximitySensor=null;   Tex

3、tViewaccTextView=null;   /**Calledwhentheactivityisfirstcreated.*/   @Override   publicvoidonCreate(BundlesavedInstanceState){       super.onCreate(savedInstanceState);       setContentView(R.layout.main);   sensormanager=(SensorManager)getSystemService(SENSOR_SERVICE);   accSensor

4、=sensormanager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);   lightSensor=sensormanager.getDefaultSensor(Sensor.TYPE_LIGHT);   proximitySensor=sensormanager.getDefaultSensor(Sensor.TYPE_PROXIMITY);   accTextView=(TextView)findViewById(R.id.textview_name);   }      SensorEventListen

5、erlsn=newSensorEventListener(){         publicvoidonSensorChanged(SensorEvente){       if(e.sensor==accSensor){           Log.d("sensor","foundaccsensor");               x=e.values[SensorManager.DATA_X];                 y=e.values[SensorManager.DATA_Y];                 z=e.values[S

6、ensorManager.DATA_Z];               accTextView.setText("x="+x+",y="+y+",z="+z);       }       elseif(e.sensor==lightSensor){           Log.d("sensor","foundlightsensor");               accTextView.setText("datais"+e.values[0]);       }       elseif(e.sensor==proximitySensor){ 

7、          Log.d("sensor","foundproximitysensor");               accTextView.setText("distanceis"+e.values[0]);       }       }          publicvoidonAccuracyChanged(Sensors,intaccuracy){         }     };       @Override      protectedvoidonResume(){          super.onResume();     //
