Android ช่วยทำการส่งค่าไปอีก Activity ด้วยครับ ส่งค่าของ SQLite Intent เพื่อเอาไปเช็คเงื่อนไข SELECT ของ Database

final FoodTypeDBClass myDb = new FoodTypeDBClass(this);
String myData[] = myDb.SelectAllData();   

ListView listViewFoodType = (ListView)findViewById(R.id.listViewFoodType); 
     		  
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
     		                	android.R.layout.simple_list_item_1, myData);
     		        
listViewFoodType.setAdapter(adapter);
     	
final FoodDBClass FoodDb = new FoodDBClass(this);
final ArrayList<HashMap<String, String>> FoodList = FoodDb.SelectAllData();
     	
listViewFoodType.setOnItemClickListener(new OnItemClickListener() {
	public void onItemClick(AdapterView<?> myAdapter, View myView, int position, long mylng) {

	     Intent newActivity = new Intent(MainActivity.this,ShowFoodActivity.class);
	     newActivity.putExtra("FoodIDType", FoodList.get(position).get("food_calorie_type").toString());
	     startActivity(newActivity);
	}       
});

String setFoodIDType = getIntent().getStringExtra("FoodIDType");
			
String strSQL = "SELECT * FROM " + TABLE_FOOD + " WHERE food_calorie_type = " + setFoodIDType;

public ArrayList<HashMap<String, String>> SelectAllData(){
try{
	ArrayList<HashMap<String, String>> MyArrList = new ArrayList<HashMap<String,String>>();
	HashMap<String, String> map;
			
	SQLiteDatabase db;
	db = this.getReadableDatabase();
			
	String setFoodIDType = getIntent().getStringExtra("FoodIDType");
			
	String strSQL = "SELECT * FROM " + TABLE_FOOD + " WHERE food_calorie_type = " + setFoodIDType;
	Cursor cursor = db.rawQuery(strSQL, null);
			
	if(cursor != null){
		if(cursor.moveToFirst()){
			do{
				map = new HashMap<String, String>();
				map.put("food_calorie_id", cursor.getString(0));
				map.put("food_calorie_name", cursor.getString(1));
				map.put("food_calorie_qty", cursor.getString(2));
				map.put("food_calorie_volume", cursor.getString(3));
				map.put("food_calorie_kcal", cursor.getString(4));
				map.put("food_calorie_type", cursor.getString(5));
				MyArrList.add(map);
			} while (cursor.moveToNext());
		}
	}
	cursor.close();
	db.close();
	return MyArrList;
	} catch (Exception e) {
		return null;
	}
}
