你能帮帮我吗？

public void getCategory() {

    AlertDialog alertDialog;


    LayoutInflater inflater = (LayoutInflater) getApplicationContext().getSystemService(LAYOUT_INFLATER_SERVICE);
    View layout = inflater.inflate(R.layout.spinner_alert, lV_new_spesa);

    //Apriamo il db creato tramite MissioniDb a cui passo il contesto della classe attuale ovvero Lista_Missioni
    SpinnerDb sdb=new SpinnerDb(getApplicationContext());

    //apriamo il db
    sdb.open();  

    //Chiamo la Query che in questo caso è un all
    c=sdb.fetchSPINNER();

    startManagingCursor(c);

    // create an array to specify which fields we want to display
    String[] from = new String[]{SpinnerDb.SpinnerMetaData.SPINNER_CAT_KEY};

    // create an array of the display item we want to bind our data to
    int[] to = new int[]{android.R.id.text1};

    // create simple cursor adapter
    SimpleCursorAdapter spadapter =
      new SimpleCursorAdapter(this, android.R.layout.simple_spinner_item, c, from, to );
    spadapter.setDropDownViewResource( android.R.layout.simple_spinner_dropdown_item );

    stopManagingCursor(c);
    //Chiudo il db perchè ho finito di riempire la mia list view
    sdb.close();


    Spinner spin = (Spinner) layout.findViewById(R.id.spinQ);
    //I get the error in the following line:
    spin.setAdapter(spadapter);

    //Definisco cosa deve fare quando un elemento di tale spinner viene premuto
    spin.setOnItemSelectedListener(new SpinnerItemSelectedListener());

    Builder builder = new AlertDialog.Builder(this);
    builder.setView(layout);
    alertDialog = builder.create();
    alertDialog.show();
