有人能举例说明如何使用接近传感器吗？我试着用和其他传感器一样的方式，但它不起作用.
这是我一直在使用的代码片段:
final SensorManager mSensorManager;
final Sensor mproximity;
mSensorManager = (SensorManager)getSystemService(SENSOR_SERVICE);
mproximity = mSensorManager.getDefaultSensor(Sensor.TYPE_PROXIMITY);
mSensorManager.registerListener(new SensorListener(){
public void onAccuracyChanged(int arg0, int arg1) {
// TODO Auto-generated method stub
Toast.makeText(test.this,"proximity sensor accu ", Toast.LENGTH_SHORT).show();
}
public void onSensorChanged(int arg0, float[] arg1) {
// TODO Auto-generated method stub
Toast.makeText(test.this,"proximity sensor ", Toast.LENGTH_SHORT).show();
}
}, Sensor.TYPE_PROXIMITY, 1);
请告诉我哪里出了问题.
