使用接近传感器与onSensorChanged

Question

我使用接近传感器来增加TextView中的数字，它的工作，但它以两个增量触发0 2 4 6 8。我希望得到1的增量，可能吗?

TextView text ;
SensorManager sm ;
Sensor Proxsens;
int i=0 ;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    text =(TextView)findViewById(R.id.text_id);
    sm = (SensorManager)getSystemService(SENSOR_SERVICE);
    Proxsens = sm.getDefaultSensor(Sensor.TYPE_PROXIMITY);
    sm.registerListener(this,Proxsens,SensorManager.SENSOR_DELAY_NORMAL);
}
@Override
public void onSensorChanged(SensorEvent event) {
    text.setText(String.valueOf(i));
    i++;
//  text.setText(String.valueOf(event.values[0]));
}
@Override
public void onAccuracyChanged(Sensor sensor, int accuracy) {
}

Answer 1

@Override
public void onSensorChanged(SensorEvent event){
    if (event.values[0] == 0) {
        text.setText(String.valueOf(i));
        i++;
    }
}
