使用單個onclick（視圖視圖）方法處理多個imgeview方法

Question

我通過充氣一個佈局並將id設置爲該圖像視圖，以編程方式創建多個圖像視圖。所有這些任務我在循環中執行。我想在這些以編程方式創建的圖像視圖上設置點擊偵聽器。我設置了onclick監聽器，但它不工作。

我的代碼： -

mainlinearlayout.xml

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:id="@+id/linear_layout_breakfast" 
android:layout_width="match_parent" 
android:layout_height="wrap_content" 
android:background="@color/colorLightWhiteShade" 
android:orientation="horizontal"> 

layout2.xml

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:orientation="horizontal" 
android:gravity="center" 
android:weightSum="10" 
android:padding="@dimen/margin_small" 
android:layout_width="match_parent" 
android:layout_height="match_parent"> 


<TextView 
    android:id="@+id/textview_breakfast_food_name_layout2" 
    android:layout_width="0dp" 
    android:layout_height="wrap_content" 
    android:layout_weight="9" 
    android:layout_alignParentLeft="true" 
    android:gravity="left" 
    android:ellipsize="end" 
    android:singleLine="true" 
    android:layout_marginLeft="5dp" 
    android:textColor="@android:color/black" 
    android:text="Food Name" /> 

<ImageView 
    android:id="@+id/delete_button_layout2" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_weight="0.5" 
    android:layout_toLeftOf="@+id/edit_button_layout2" 
    android:gravity="center" 
    android:src="@drawable/btn_delete"/> 

<ImageView 

    android:id="@+id/edit_button_layout2" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_weight="0.5" 
    android:layout_alignParentRight="true" 
    android:gravity="center" 
    android:src="@drawable/btn_edit"/> 

</LinearLayout> 

MainActivity.class

LinearLayout layout =(LinearLayout) findViewById(R.id.linear_layout_breakfast); 
for (int i = 0; i < breakfastArraylistSize; i++) { 
     View view = LayoutInflater.from(this).inflate(R.layout.layout2_breakfast, null); 
     TextView textview_food_name = (TextView) view.findViewById(R.id.textview_breakfast_food_name_layout2); 
     Log.d("textview_food_name id", String.valueOf(1 + (i * 3))); 
     textview_food_name.setId(1 + (i * 3)); textview_food_name.setText(foodBreakfastDiaryDetailsArrayList.get(i).get("foodName")); 
     Log.d("foodName", foodBreakfastDiaryDetailsArrayList.get(i).get("foodName")); 
     layout.addView(view); 

     imageview_delete_breakfast = (ImageView) view.findViewById(R.id.delete_button_layout2); 
     imageview_delete_breakfast.setId(2 + (i * 3)); 
     imageview_delete_breakfast.setOnClickListener(this); 
     Log.d("imageview_delete_breakfast id", String.valueOf(DiaryScreenActivity.this.imageview_delete_breakfast.getId())); 

    layout.setOrientation(LinearLayout.VERTICAL); 
    String foodid_Breakfast = ""; 
     foodid_Breakfast = foodBreakfastDiaryDetailsArrayList.get(i).get("foodID"); 
     int imageViewDeletePos = getIndexOFValue(foodid_Breakfast, foodBreakfastDiaryDetailsArrayList); 
     Log.d("imageViewDeletePos", String.valueOf(imageViewDeletePos)); 
     ImageView imageview_edit = (ImageView) view.findViewById(R.id.edit_button_layout2); 
     imageview_edit.setId(3 + (i * 3)); 
     imageview_edit.setOnClickListener(this); 
} 

Onclicklistener

@Override 
public void onClick(View v) { 
if (v.getId() == DiaryScreenActivity.this.imageview_delete_breakfast.getId()) { 

Log.d("imageview_delete_breakfast id", String.valueOf(DiaryScreenActivity.this.imageview_delete_breakfast.getId())); 
     new AlertDialog.Builder(this) 
       .setTitle("Delete food") 
       .setMessage("Are you sure you want to delete this food?") 
       .setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() { 
        public void onClick(DialogInterface dialog, int which) { 
         // continue with delete 

         // delete food item 
         DataBaseHelper dataBaseHelper = DataBaseHelper.getInstance(getApplicationContext()); 
         try { 
          dataBaseHelper.openDataBaseC("M"); 

          for (int i = 0; i < foodBreakfastDiaryDetailsArrayList.size(); i++) { 

           String foodid_Breakfast = foodBreakfastDiaryDetailsArrayList.get(i).get("foodID"); 
           Log.d("foodid_Breakfast", foodid_Breakfast); 
           int imageViewDeletePos = getIndexOFValue(foodid_Breakfast, foodBreakfastDiaryDetailsArrayList); 
           Log.d("imageViewDeletePos", String.valueOf(imageViewDeletePos)); 
          } 

          dataBaseHelper.closeC("M"); 

         } catch (SQLException e) { 
          // TODO Auto-generated catch block 
          e.printStackTrace(); 
         } 

        } 
       }) 
       .setNegativeButton(android.R.string.no, new DialogInterface.OnClickListener() { 
        public void onClick(DialogInterface dialog, int which) { 
         // do nothing 
        } 
       }) 
       .setIcon(android.R.drawable.ic_dialog_alert) 
       .show(); 

    } 
}

添加的onClick內循環。像：

imageview_delete_breakfast.setOnClickListener(new View.OnClickListener() { 
       @Override 
       public void onClick(View v) { 
        // do what you want for individual click 
       } 
      });
