问题描述

我编码一个Android应用程序，但我必须使用加速度计一些麻烦。奇怪的是，我的功能onSensorChanged（）不叫，我不知道为什么：/你能帮我吗？ :)这里是我的code：

I am coding an Android application but I have some trouble using the accelerometer. Strangely, my function onSensorChanged() is not called and I don't know why :/ Could you help me please ? :) Here's my code :

@SuppressLint("NewApi")
public class Game extends Activity implements SensorEventListener {

SensorManager sensorManager;
ImageView vaisseau;
TextView test;
RelativeLayout rl;

@SuppressLint("NewApi") @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);

    sensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
    sensorManager.registerListener(this,sensorManager.getDefaultSensor(Sensor.TYPE_ORIENTATION),SensorManager.SENSOR_DELAY_GAME);

    setContentView(R.layout.game);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);

    Display ecran = getWindowManager().getDefaultDisplay();
    int largeur= ecran.getWidth();
    int hauteur= ecran.getHeight();

    Drawable d = getResources().getDrawable(R.drawable.spaceship);
    int largeurVaisseau = d.getIntrinsicWidth();

    vaisseau = new ImageView(this);
    vaisseau.setImageResource(R.drawable.spaceship);
    rl = (RelativeLayout)findViewById(R.id.layout_game);
    vaisseau.setX(largeur/2 - largeurVaisseau);
    vaisseau.setY(hauteur-hauteur*10/100);
    rl.addView(vaisseau);

    test = new TextView(this);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    return true;
}

public void onSensorChanged(SensorEvent event) {
    if (event.sensor.getType() == Sensor.TYPE_ACCELEROMETER){
        test.setText(Float.toString(event.values[0]));
        rl.addView(test);
    }
}

@Override
public void onAccuracyChanged(Sensor sensor, int accuracy) {
}

@Override
protected void onResume() {
    super.onResume();
    sensorManager.registerListener(this,sensorManager.getDefaultSensor(Sensor.TYPE_ORIENTATION),SensorManager.SENSOR_DELAY_GAME);
}

@Override
protected void onPause() {
    super.onPause();
    sensorManager.unregisterListener(this);
}
}

在此先感谢:)
