AlertDialog.Builderを使用してカスタムAlertDialogクラスを構築する

Question

私はどのように表示したいのかをカスタマイズしたAlertDialogを継承するクラスFoodDialogを持っています。

私は今AlertDialog.Builderを使用して、正/負のボタンを編集したいのです、私はビルダーを使用してFoodDialogのインスタンスを構築しようとすると、しかし、私はビルダーがAlertDialogを求めている「互換性のないタイプ」というエラーが直面しています代わりにAlertDialogという拡張子を付けています - これはどういう意味ですか？

私のカスタムAlertDialogクラスFoodDialogの肯定/否定ボタンを編集する方法はありますか？

以下は私のFoodDialogクラスです。私が持っているはい/いいえのボタンは自分で作ったものですが、柔らかいキーボードが現れると、これらのボタンが見えなくなるので代わりにAlertDialog.Builderの一部が表示されます：

public class FoodDialog extends AlertDialog implements OnClickListener { 

    private TextView foodNameTextView, foodDescTextView, foodPortionTextView, catTextView, qtyText, cal, fat, sFat, carb, sug, prot, salt, imageTxt, 
      measureText; 
    private EditText foodQty; 
    private ImageView foodImage; 
    private ImageButton yesBtn, noBtn; 
    private int foodID, totalCal; 
    private Bitmap image; 
    private String user, portionType, foodName, foodDesc, cat, totalCalString, totalFatString, 
      totalSFatString, totalCarbString, totalSugString, totalProtString, totalSaltString, portionBaseString;

    public FoodDialog(Context context){ 
     super(context); 

    } 

    public FoodDialog(Context context, int foodID, String imgLocation, final String user) { 
     super(context, android.R.style.Theme_Holo_Light_Dialog); 
     this.setTitle("Confirm?"); 
     setContentView(R.layout.dialog_layout);

次のようにリスナーをクリックして、ボタンをキャッチすることができます：

yesBtn.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      //yes button click code here 
     } 
    }); 

noBtn.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      //no button click code here 
     } 
    }); 

あなたのリスナーが発射されているかどうかを確認するためにlogcatを使用することができます。
