Android viewbinder 我无法使用VewBinding和SensorEventListener从非活动类设置按钮文本

我得到了日志“inIt”。这就好像绑定从那里不起作用一样。 如果我把我的Accelerator类代码带到活动中，它就会起作用，我只想把事情分开

我的活动

@Override
protected void onResume() {
    super.onResume();
    Capteur.mSensorManager.registerListener(new Accelerometre(getApplicationContext()), Capteur.mAccelerometer, SensorManager.SENSOR_DELAY_NORMAL);
}

我的俘虏班

public class Capteur {
public static SensorManager mSensorManager = null;
public static Sensor mAccelerometer = null;
public Context mcontext;
private ActivityMelimeloBinding binding;
public static SensorEventListener mSensorEventListener;


public Capteur(final Context context) {
    this.mcontext = context;
    mSensorManager = (SensorManager) context.getSystemService(Context.SENSOR_SERVICE);
    mAccelerometer = mSensorManager.getDefaultSensor(Sensor.TYPE_ROTATION_VECTOR);

}

}

我的加速计课

public class Accelerometre extends ViewGroup implements SensorEventListener {
public Context mcontext;
private ActivityMelimeloBinding binding;
public Accelerometre(final Context context) {
    super(context);
    this.mcontext = context;
}

@Override
protected void onLayout(boolean b, int i, int i1, int i2, int i3) {
}

@Override
public void onSensorChanged(SensorEvent sensorEvent) {
    binding = ActivityMelimeloBinding.inflate(LayoutInflater.from(mcontext),this,true);
    binding.buttonRandom.setText("cooooocc");
    Log.d("pppp","inIT");
