Android - กรองข้อมูลจาก listview เมื่อคลิกที่รายการนั้น ก็ให้แสดงข้อมูลของรายการที่คลิกบน AlertDialog แต่ค่าที่แสดงออกมามันไม่ใช่ค่าล่าสุดที่กรองได้

EditText  inputSearch = (EditText) findViewById(R.id.inputSearch);
inputSearch.addTextChangedListener(new TextWatcher() {
             
            @Override
            public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {
                ShowFoodActivity.this.sAdap.getFilter().filter(cs);   
            }
             
            @Override
            public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,int arg3) {
            	
            }
             
            @Override
            public void afterTextChanged(Editable arg0) {    
            	ListView1.setOnItemClickListener(new OnItemClickListener() {
        			public void onItemClick(AdapterView<?> myAdapter, View myView, int position, long mylng) {
        				sFoodName = FoodList.get(position).get("food_calorie_name").toString();
        				Toast.makeText(getApplicationContext(), ""+sFoodName, Toast.LENGTH_LONG).show();
        				
        			}
            	});
            }
        });
       
        // ListView OnClick
        ListView1.setOnItemClickListener(new OnItemClickListener() {
			public void onItemClick(AdapterView<?> myAdapter, View myView, int position, long mylng) {
	
				sFoodName = FoodList.get(position).get("food_calorie_name").toString();
				sFoodKcal = FoodList.get(position).get("food_calorie_kcal").toString();
				
				AlertDialog.Builder alert = new AlertDialog.Builder(ShowFoodActivity.this);

		        final NumberPicker np = new NumberPicker(ShowFoodActivity.this);
		        
		        np.setDescendantFocusability(NumberPicker.FOCUS_BLOCK_DESCENDANTS);
				np.setMinValue(1);
				np.setMaxValue(10);
				np.setWrapSelectorWheel(false);

		        alert.setIcon(android.R.drawable.btn_star_big_on);
		        alert.setTitle("เพิ่มรายการ");
		        alert.setView(np);
		        alert.setMessage(sFoodName + " " + "\n"
										+ "ปริมาณแคลอรี่ : " + sFoodKcal + " Kcal" + "\n"
										+ "ระบุจำนวน : ");

		        alert.setNegativeButton("บันทึก", new DialogInterface.OnClickListener() {
					public void onClick(DialogInterface dialog, int which) {
						
						final int Kcal = Integer.parseInt(sFoodKcal);
						sTotal = Kcal * np.getValue();
						sNum =  np.getValue();
						SaveData();
					}
				});
		        alert.setPositiveButton("ยกเลิก", new DialogInterface.OnClickListener() {
					
					@Override
					public void onClick(DialogInterface dialog, int which) {
						dialog.cancel();
