Android代码----传感器---光传感

一个简单的小Demo 测试手机光传感：

具体代码如下：

[java代码]Sample.java

    package com.example.test_sensor_light;                import org.openintents.sensorsimulator.hardware.Sensor;        import android.app.Activity;        import android.hardware.SensorManager;        import android.os.Bundle;        import android.widget.TextView;                public  class Sample extends Activity implements  android.hardware.SensorEventListener {                        private TextView myTextView1;                    private SensorManager mySensorManager;                    @Override            public void onCreate(Bundle savedInstanceState) {                super.onCreate(savedInstanceState);                setContentView(R.layout.main);                myTextView1 = (TextView) findViewById(R.id.myTextView1);                mySensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);                    }                    @Override            protected void onResume() {                mySensorManager.registerListener(                        this,                        mySensorManager.getDefaultSensor(Sensor.TYPE_LIGHT),                        SensorManager.SENSOR_DELAY_GAME                        );                super.onResume();            }                    @Override            protected void onStop() {                // TODO Auto-generated method stub                mySensorManager.unregisterListener(this);                super.onStop();            }            @Override            protected void onPause() {                mySensorManager.unregisterListener(this);                super.onPause();            }                    @Override            public void onAccuracyChanged(android.hardware.Sensor sensor, int accuracy) {                // TODO Auto-generated method stub                            }                    @Override            public void onSensorChanged(android.hardware.SensorEvent event) {                // TODO Auto-generated method stub                float[] values = event.values;                int sensorType = event.sensor.TYPE_LIGHT;                if (sensorType == Sensor.TYPE_LIGHT) {                    myTextView1.setText("当前光的强度为："+values[0]);                      }            }                }
