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 boolean addData(String item, String Price,String amount){

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());

Merging cursor only gives back first cursor in clickEvent

Passing the cursor of position clicked but when doing so log is showing me I am getting only the first row no matter where I click.
holder.mTopCardView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(mCallback != null) {
mCallback.onTopListClick(cursor);
notifyDataSetChanged();
Log.i("FROMCLICK", DatabaseUtils.dumpCursorToString(cursor));
}
}
});
The log inside the CursorAdapter onClickListener is showing only the first rows cursor even if I click 20 rows down the list.
#Override
public void onTopListClick(Cursor cursor) {
Log.i("FistClickBeforePassing", DatabaseUtils.dumpCursorToString(cursor));
BottomFragment bottomFragment = (BottomFragment) getSupportFragmentManager().findFragmentById(R.id.bottomFragment);
bottomFragment.refreshList(cursor);
}
Same thing here before passing to the BottomFragment.
public void refreshList(Cursor cursor) {
Log.i("RIGHTBEFOREREFRESH", DatabaseUtils.dumpCursorToString(cursor));
String mEmployeeNumber = cursor.getString(1);
Log.i("REFRESHLISTNUMBER", mEmployeeNumber);
dbHandler = EmployeeDBHandler.getInstance(getContext());
db = dbHandler.getReadableDatabase();
mNewBottomCursor = db.rawQuery("SELECT * FROM " + table + " WHERE " +
/*"Employee_number" + "!=" + mStartingEmployeeID + " AND " +*/
"Manager_employee_number" + "=" + mEmployeeNumber + " ORDER BY " +
"Last_name" + " ASC", null);
Log.i("THECURSOR ", DatabaseUtils.dumpCursorToString(mNewBottomCursor));
BottomListCursorAdapter bottomListCursorAdapter = new BottomListCursorAdapter(getActivity(), cursor);
bottomListCursorAdapter.swapCursor(mNewBottomCursor);
mBottomListView.setAdapter(bottomListCursorAdapter);
}
}
Get the same cursor here for the log but do not get the same employee_number the cursor has for the REFRESHLISTNUMBER log statement. That is a random number from the list.
Not sure why the cursor isnt being passed correctly. I have a details button on each row that displays info from the cursor for each row and that is displaying correctly.

Maybe something is happening with my MergeCursor in TopFragment that is messing with the curors? If so, not sure how to fix it or why it would be happening.

Fixed by adding a line of code to the setClickListener of the mTopCardView in the TopListCursorAdapter.
cursor.moveToPosition(position);

Check Row_id in database with other value in RecyclerView Adapter

This is structure of my json respose :
{
"data": [
{
"id": 23,
"title": "this is title",
"description": " this is desc",
"date": "21/2/16",
"authorname": "john smith",
"authorpic": "http://xtryz.com/users/1462862047com.yahoo.mobile.client.android.yahoo_128x128.png",
"filename": "1463770591.MP4",
"downloadlink": "http://xyrgz.com/download.zip",
"downloadcnt": "24"
},
...
]
And with clicking one Buton in each row of RecyclerView I save that json row In the Database . Know for some work I need to know is this json row exist in the Database or no ? for doing this work , I Want to use the id in the database and id of the json . and if id of the database same to id of the json , doing some work and else .

And this is Database Structure :
(question_id is the id of question)
Now i need to compare id of database and id of the json in adapter . but i don't know how can i do this .

private ArrayList<ModelQuestion> questionha;
private ArrayList<ModelQuestion> jsonArrList;
//pass your json arraylist too in constructor from your main activity
public AdapterRecyclerQuestion(Context context, ArrayList<ModelQuestion> questionha,ArrayList<ModelQuestion> jsonArrList) {
this.context = context;
this.questionha = questionha;
this.jsonArrList = jsonArrList;
}
#Override
public void onBindViewHolder(final ViewHolder holder, final int position) {
for(int i=0;i<jsonArrList.size();i++)
{
//Check your id here
if(jsonArrList.get(i).getId().equalsIgnoreCase(questionha.get(position).getId()))
}
}

Android and delete items from ListView and sqlite database

I'm trying to remove items from listView and the database, but I can not cope. I throw the code, and I hope to help. I throw code with showList on screen and save to database sqlite. Any idea? I am also a beginner any help would be greatly appreciated. I was looking at tutorials and removal does not work for me. I have no idea why. And how do though to purge my list after exiting application? Because when I go to the application's data in listView are still visible.

Delete on db

I think You need to pass Id which is autoIncreament instead of possition.
ie.
int index=propertyList.get(position).get(Id);
Button deletePropertyItem = (Button) vi.findViewById(R.id.DeletePropertyListItem);
deletePropertyItem.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
propertyList.remove(index);
notifyDataSetChanged();
}
});
