ANDROID_MARS学习笔记_S05_001_用SensorManager获取传感器

1. 

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //得到SensorManager对象
        sensorManager = (SensorManager)getSystemService(Context.SENSOR_SERVICE);
        
        sensorButton = (Button)findViewById(R.id.sensorButton);
        
        sensorButton.setOnClickListener(new OnClickListener() {
            
            @Override
            public void onClick(View v) {
                //通过调用getSensorList方法，得到当前手机当中所有的传感器
                List<Sensor> sensors = sensorManager.getSensorList(Sensor.TYPE_ALL);
                for (Sensor sensor : sensors) {
                    System.out.println(sensor.getName());
                }
                
                //通过调用getDefaultSensor方法，获取某一个类型的默认传感器
                Sensor sensor = sensorManager.getDefaultSensor(Sensor.TYPE_LIGHT);
            }
        });
    }
