Update textview data sqlite Android

I have a textview that gets data from sqlite database but when I delete a row,or change it ,I also want to change what the textview has,the data the textview contains is basically the sum of all rows specific column,so how can I update the textview when updating sqlite data?
here is my main code:

And here is my DatabaseHelper.java

Cursor data = db.rawQuery(query, null);
return data;
}
public String getPriceSum(){
SQLiteDatabase db = this.getWritableDatabase();
String query = "SELECT COALESCE(SUM(Price), 0) FROM " + TABLE_NAME;
Cursor price = db.rawQuery(query, null);
String result = "" + price.getString(0);
price.close();
db.close();
return result;
}
public boolean ifExists()
{
SQLiteDatabase db = this.getWritableDatabase();
Cursor cursor = null;
String checkQuery = "SELECT * FROM " + TABLE_NAME + " LIMIT 1";
cursor= db.rawQuery(checkQuery,null);

cursor.close();
return exists;
}
public void delete(String nameofrow) {
SQLiteDatabase db = this.getWritableDatabase();
db.execSQL("delete from "+TABLE_NAME+" where "+NAME+"='"+nameofrow+"'");
}
}
Any help?!

The method getPriceSum() should return the sum and not a Cursor:
public String getPriceSum(){
SQLiteDatabase db = this.getWritableDatabase();
String query = "SELECT COALESCE(SUM(Price), 0) FROM " + TABLE_NAME;
Cursor c = db.rawQuery(query, null);
String result = "";
if (c.moveToFirst()) result = "" + c.getString(0);
c.close();
db.close();
return result;
}
I don't think that you need the if block:
if (mDatabaseHelper.ifExists()) {
.......................
}
All you need to do is:
total.setText(mDatabaseHelper.getPriceSum());

edittext value changes position while scrolling in custom listview in android

I have created a custom list view with 6 colomns. Each row is populated.
the first 3 fields are textviews,which are filled from db. Then a spinner and the last two edittexts.

The database code where i am saving data is as follows:
public void Insert_phone_contact(String [] contact){
try{
SQLiteDatabase DB = this.getWritableDatabase();
ContentValues cv = new ContentValues();
for(int i=0;i<contact.length;i++){
// put all values in ContentValues
if (contact[i] !=null){
cv.put(CONTACT_NAME, ""+contact[i]);
DB.insert(TABLE_CONTACTS, null, cv);
}// insert in db
}
DB.close(); // call close
}
catch(Exception ex){
Log.e("Error in phone contact insertion", ex.toString());
}
}
ContactTable code in database is as :
// define table name
public static final String TABLE_CONTACTS = "CONTACTS_TABLE";
//define column of TABLE_CONTACTS
public static final String KEY_CONTACTID = "_id";
public static final String CONTACT_NAME = "Contact_name";

Android - ListView Listener not working after adding multiple item at one time

My listView works well when only 1 item added to the listview at one time. But when multiple item is added, listener in listview is not wokring. Can anyone guide me what i am doing wrong here? Thanks.
Here is my listView code:

OnLongClick operates in the function of MySqlCursorAdapter. But I need setOnItemLongClickListener. I try do this function in MainActivity
ListView lvTareas = (ListView) findViewById (R.id.list);
lvTareas.setOnItemLongClickListener(new OnItemLongClickListener() {
#Override
public boolean onItemLongClick(AdapterView<?> arg0, View arg1,
int pos, long id) {
Log.d(Tag,"pos"+" "+pos);
return true;
}
});
But it not work. Help me please? what I do not correctly?

It happens due to focusability of CheckBox in my_list_item layout.
Add below line to root layout of your ListView's Item layout(my_list_item).
android:descendantFocusability="blocksDescendants"
