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
public class DatabaseHelper extends SQLiteOpenHelper {

db.execSQL(createTable);
}
#Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
db.execSQL("DROP TABLE IF EXISTS "+ TABLE_NAME);
onCreate(db);
}
public boolean addData(String item, String Price,String amount){
SQLiteDatabase db = this.getWritableDatabase();
ContentValues contentValues = new ContentValues();
contentValues.put(PRICE,Price);
contentValues.put(NAME, item);
contentValues.put(AMOUNT, amount);
Log.d(TAG, "addData: Adding " + item + " to " + TABLE_NAME);
long insert = db.insert(TABLE_NAME,null,contentValues);
if (insert == -1){
return false;
}else {
return true;
}
}
public Cursor getDataOfTable(){
SQLiteDatabase db = this.getWritableDatabase();
String query = "SELECT Name,Amount FROM " + TABLE_NAME ;
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);
boolean exists = (cursor.getCount() > 0);
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());

Why does not this AlertDialog dismiss in this situation?

I want to insert data from a text file into SQLite database :

...
}

SpliterString.getColumnValueAt(enreg[p],13),
SpliterString.getColumnValueAt(enreg[p],14));
db.insertParcelle(parcelle);
}
db.close();
}
}
}
Data inside the text file is just one row ( data are represented like a csv but separator is | ) :
1||010-01-02|PARC-0001|PARCELLE DROUDOUDOU|10||2000.00|500.00|1500.00||10, Av Place de l'Independance - CENTRE VILLE|01/02/2000|10/02/2005|CENTRE VILLE|
The problem is that the AlertDialog is never dismissed ! There is no error ! So what is wrong ?

Android Trouble saving text from Edit Text View to database

In my application, I am allowing user to send a alert message to some numbers. User can write any text of his own choice in the EditText or he can select a text from the pre-defined text from the spinner. Earlier I was saving the text to the SharedPreferences but now I want it to be in SQLite.I am able to save the contact numbers to the database for which user wants to send the message but I am having trouble in saving the message to database. I want that when user entered his own text or selected any text from the spinner after that he press save button and the text is saved to database.Please Help.
P.S _ I think am having trouble in calling method from database to button onclick.
Please have a look on my code and suggest me what to do.

Simply call the method for inserting or updating the message into database in your button's click and before calling that method just get the value of EditText into some variable and pass that variable as parameter for inserting into database.
Try out as below:
save.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
String str = message.getText().toString();
dbHelper.updateMsg(str);
}
});
EDITED:
public boolean updateMsg(String msg) {
ContentValues values = new ContentValues();
values.put(COLUMN_MSG, msg);
SQLiteDatabase db = this.getReadableDatabase();
return db.update(TABLE_NAME_MSG, values, COLUMN_ID_MSG +"=1"+, null)>0;
}

load contacts like viber in android

I want to load contacts from android device, I have used different methods but contacts load so slow,
I am using CommanDataKinds,
I am getting index of column out of the loop(only one, then use
that variable in loop).
also I want to use fast scrolling technique like viber.
What exactly I need is viber contact list, It is fast, use sections, fast scrolling etc..

try with this dude :) best of luck

constants.dismissDialog();
adapter = new ContactsAdapter(cntx);
contactsList.setAdapter(adapter);

}
and this is my contact wrapper class
public class ContactsWrapper {
private long contactId;
private String displayName,displayNumber,lookUp;
public boolean checked = true;
int color_string;
public ContactsWrapper(long contactId, String displayName, String displayNumber, String lookUp, boolean checked,int color_string) {
// TODO Auto-generated constructor stub
this.contactId = contactId;
this.displayName = displayName;
this.displayNumber = displayNumber;
this.lookUp = lookUp;
this.checked = checked;
this.color_string =color_string;
}
public String getLookUp() {
return lookUp;
}
public int getColor_string() {
return color_string;
}
public boolean isChecked() {
return checked;
}
public long getContactId() {
return contactId;
}
public String getDisplayName() {
return displayName;
}
public String getDisplayNumber() {
return displayNumber;
}
public void setChecked(boolean checked) {
this.checked = checked;
}
}
