Android，加速度計不停止不知道爲什麼？

Question

任何人都可以幫助我爲什麼不加速度計nőt停止？ 有unregisterListener行，但沒有。

下面是代碼：

public class Festivale extends Activity implements SensorEventListener { 

Button button; 
CheckBox video, gps, acc; 
Boolean recording = false; 
public static SQLiteDatabase db; 
String strlocation; 
String city; 
private SensorManager sensorManager; 
Chronometer myChronometer; 
EditText myEditText; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 
    myChronometer = (Chronometer) findViewById(R.id.chronometer); 
    myEditText = (EditText) findViewById(R.id.editText1); 

    addDataBase(); // adatbázist hoz létre 
    addListenerOnButton(); 

} 

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    AlertDialog.Builder builder = new AlertDialog.Builder(this); 
    builder.setMessage(
      "Készítette: Lakatos Dávid\nEmail: david.lakatos@gmail.com\nTel.: +3620/427-1166") 
      .setCancelable(false) 
      .setPositiveButton("OK", new DialogInterface.OnClickListener() { 
       public void onClick(DialogInterface dialog, int id) { 
       } 
      }); 
    AlertDialog alert = builder.create(); 
    alert.show(); 
    return true; 

} 

private void addGPSListener() { 

    String text = myEditText.getText().toString(); 

    float f = Float.valueOf(text.trim()).floatValue(); 
    float update = f * 1000; 

    if (update < 100 || update > 1000000) { 
     AlertDialog alertDialog; 
     alertDialog = new AlertDialog.Builder(Festivale.this).create(); 
     alertDialog.setTitle("Hiba!"); 
     alertDialog.setMessage("Helytelen frissítési idõ:\n" + update

如何嘗試這種加速度計註銷你（對我的作品）：

/**

    public void useAccelerometer(boolean use) { 
     if(use == true) {

     else {
