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 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());

Focusable EditText in ListView and Swipe to Dismiss

I have a MainActivity, CustomListAdapter, customlistItem.xml, mainlayout.xml, SwipeDismissListViewTouchListener.java, SwipeDismissTouchListener.java.
I'm using a this code(Swipe to Dismiss).
I want to make a focusable(editable) EditText in ListView & onItemClickListener ListView & Swipe to Dismiss ListView.
My Code works well focusable(editable) EditText in ListView & onItemClickListener ListView.But didn't work the Swipe to Dismiss ListView.
If I make a new Item, then Swipe to Dismiss ListView works well, but Didn't work focusable(editable) EditText in ListView & onItemClickListener ListView.
I think there is a problem with TouchListener code.(dupplicated)
What am I Supposed to do?

How to prevent duplicate phone contacts to be added in database?

In my Android application, I have a List of Phone Contacts. I want to add these contacts in private list by selection through CheckBoxe and onButtonClick. What I want here is that if contacts are already present there in database then they should not be added. How can i do so ? Please help.

For an ArrayAdapter, notifyDataSetChanged() only works if you use the add, insert, remove, and clear functions on the Adapter.
Try following code:
public void refresh(ArrayList<Person>list)
{
data.clear();
data.addAll(list);
this.notifyDataSetChanged();
}

Do something like this inside activity
CallListViewCustomAdapter thadapter=new CallListViewCustomAdapter(MainActivity.this, R.layout.list,numAl);
NumberList.setAdapter(thadapter);
#Override
public void onClick(View v) {
thadapter.notifyDataSetChanged();
}
});

Call notifyDataSetChanged() and recall adapter

Call notifyDataSetChanged() method to the ListView adapter object.

Why is the first line always crossed out?

Why is the first line is always crossed out?

setPaintFlags changes are persistent, so I suspect that your function gets called twice, the first time cBox.setChecked(true) is executed, but the second time cBox.setChecked(false) is executed, so the flags are not reset. Thus:
if (cBox.isChecked())
{
Log.d(Tag, " pos=" + pos);
txtTitle.setPaintFlags(txtTitle.getPaintFlags() | Paint.STRIKE_THRU_TEXT_FLAG);
txtTitle1.setPaintFlags(txtTitle.getPaintFlags() | Paint.STRIKE_THRU_TEXT_FLAG);
}
else
{
Log.d(Tag, "!pos=" + pos);
txtTitle.setPaintFlags(txtTitle.getPaintFlags() & ~Paint.STRIKE_THRU_TEXT_FLAG);
txtTitle1.setPaintFlags(txtTitle.getPaintFlags() & ~Paint.STRIKE_THRU_TEXT_FLAG);
}
