當我點擊微調框時出錯

Question

我想用自定義的ArrayAdapter填充微調框。我認爲微調器是正常填充的，但是當應用程序打開它時，會出現錯誤。

Obs：我不會說英語很好，對不起。

Obs2：我這樣做，用ListView，它工作得很好。現在，隨着微調...

我的代碼：

private void carregarSpinner() { 
    Spinner spinner = (Spinner) findViewById(R.id.CateSpinner); 
    DataBase db = new DataBase(this); 
    Cursor cursor = db.getData("SELECT * FROM Categoria"); 
    ArrayList<Categoria> txts = new ArrayList<Categoria>(); 
    while(cursor.moveToNext()) 
    { 
     Categoria ex = new Categoria(); 
     ex.setNome(cursor.getString(1)); 
     ex.setId(cursor.getInt(0)); 
     txts.add(ex); 
    } 
    AdapterCategoria adapter = new AdapterCategoria(this, txts); 
    spinner.setAdapter(adapter); 
    spinner.setOnItemSelectedListener(this); 
    db.closeDB(cursor); 
} 


public class AdapterCategoria extends ArrayAdapter<Categoria> { 

    private final Context context; 
    private final ArrayList<Categoria> itemsArrayList; 

    public AdapterCategoria(Context context, ArrayList<Categoria> itemsArrayList) { 

     super(context, R.id.txvCategoria, itemsArrayList); 

     this.context = context; 
     this.itemsArrayList = itemsArrayList; 
    } 

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 

     // 1. Create inflater 
     LayoutInflater inflater = (LayoutInflater) context 
      .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 

     // 2. Get rowView from inflater 
     View rowView = inflater.inflate(R.layout.categoria_model, parent, false); 

     // 3. Get the two text view from the rowView 
     TextView labelView = (TextView) rowView.findViewById(R.id.txvCategoria); 

     // 4. Set the text for textView 
     labelView.setText(itemsArrayList.get(position).getNome()); 
     labelView.setTag(itemsArrayList.get(position).getId()); 

     // 5. retrn rowView 
     return rowView; 
    } 
} 

錯誤：

Answer 1

您應該使用setDropDownViewResource（int）以指定佈局適配器應該用於顯示列表微調器選項（simple_spinner_dropdown_item是平臺定義的另一種標準佈局）。

// Specify the layout to use when the list of choices appears 
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); 

檢查文檔http://developer.android.com/guide/topics/ui/controls/spinner.html

Answer 2

你的答案就在這裏：

How to add Image to spinner in Android

部署適配器上的 'getDropDownView' 的方法。

@Override 
public View getDropDownView(int position, View convertView, ViewGroup parent) { 
    TextView label = (TextView) super.getDropDownView(position, convertView, parent); 

    PaymentType paymentType = getItem(position); 
    label.setText(paymentType.getStringResourceId()); 
    label.setCompoundDrawablesWithIntrinsicBounds(0, 0, paymentType. 
      getImageResourceId(), 0); 

    return label; 
}
