Display each row from Database on a new line in a TextView

I have created a database that stores all the correct values. I need for each row stored in the database to be displayed on a new line in one TextView.
Current Output
Current Output
After adding to database it adds on and updates current values instead of going to new line.

Insert data to database
public static void InsertOrUpdateRatingPoints(Context context, int point, SelfToSelfActivity.Rating activity) {
DBHelper dbHelper = new DBHelper(context);
SQLiteDatabase db = dbHelper.getWritableDatabase();
String[] projection = {ID, TIME, TYPE,};
String where = TYPE + " = ?";
String[] whereArgs = {String.valueOf(activity)};
String orderBy = TIME + " DESC";
Cursor cursor = db.query(TABLE_NAME, projection, where, whereArgs, null, null, orderBy);
boolean sameDay = false;
Date currentTime = Calendar.getInstance().getTime();
int StoredPoint = 0;
long lastStored = 0;
if (cursor != null) {
if (cursor.moveToFirst()) {
lastStored = cursor.getLong(cursor.getColumnIndex(TIME));
SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd");
sameDay = (sdf.format(new Date(lastStored))).equals(sdf.format(currentTime));
if (sameDay) StoredPoint = cursor.getInt(cursor.getColumnIndex(POINT));
}
cursor.close();
}
ContentValues cv = new ContentValues();
cv.put(POINT, point + StoredPoint);
if (sameDay) {
db.update(TABLE_NAME, cv, TIME + " = ?", new String[]{String.valueOf(lastStored)});
} else {
cv.put(TYPE, activity.ordinal());
cv.put(TIME, currentTime.getTime());
cv.put(POINT, point);
db.insert(TABLE_NAME, null, cv);
}
}
Execute

Display Data

I assume you want to display every item of ArrayList in separate lines.
Try this, hope this help.
TextView conciergeServicesTv = (TextView) findViewById(R.id.activity_get_quote_final_concierge_services_tv);
if (arrayListConciergeServices.size() != 0) { //ArrayList you are receiving\\
StringBuilder stringBuilder = new StringBuilder();
for (int i = 0; i < arrayListConciergeServices.size(); i++) {
if (i == arrayListConciergeServices.size() - 1) {
stringBuilder.append(arrayListConciergeServices.get(i));
} else {
stringBuilder.append(arrayListConciergeServices.get(i)).append("\n");
}
}
conciergeServicesTv.setText(stringBuilder);
} else {
conciergeServicesTv.setText("No concierge services selected");
}

Listview for SQL lite

I was following a school tutorial for sql lite, and the output was a list of buttons. Is it possible to output this to a ListView instead?
I've tried googling and youtube but somehow the tutorial I was following seems to have more files?
Confused newbie here!
Thanks in advance!
This code appears in the onCreate(Bundle savedInstanceState)
private void ShowExistingIdeas() {
Idea[] ideas = new Ideas(this).getAllIdeas();
if(ideas != null && ideas.length > 0)
{
for(int index = 0; index < ideas.length; index++)
{
Button ideaButton = new Button(this);
ideaButton.setText(ideas[index].getTitle());
final int id = ideas[index].getId();
ideaButton.setTag(id);
ideaButton.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View v) {
Intent i = new Intent(OverviewActivity.this,
EditIdeaActivity.class);
i.putExtra("id", id);
startActivityForResult(i, 0);
}
});
//!!! The bit I'm trying to change. the xml with LinearLayout1 is completely empty****
((LinearLayout) findViewById(R.id.LinearLayout1)).
addView(ideaButton);

Application stops working on mobile device but runs on emmulator

i have developed an app for 'bank simulation' which uses sqlite to create databases...
when i run the app on my mobile it stops unexpectedly....do i need to install any server to run sqlite based apps on mobile?
Thanks in advance!

I found my mistake. It is in constructor. I don`t have to create temp_db and invoke copyData();

using sqlite in BroadcastReceiver

I want perform a easy task in android, which when receiving a call the phonenumber will be matched to a number in my database. However I already read that sqlite and BroadcastReceiver are not that easy to combine. Below is the code:
public class incomingcall extends BroadcastReceiver{
String caller;
Cursor c;
#Override
public void onReceive(Context context, Intent intent) {
sqlitedatabase search = new sqlitedatabase(context);
Bundle bundle = intent.getExtras();
if(null == bundle)
return;
Log.i("IncomingCallReceiver",bundle.toString());
String state = bundle.getString(TelephonyManager.EXTRA_STATE);
Log.i("IncomingCallReceiver","State: "+ state);
if(state.equalsIgnoreCase(TelephonyManager.EXTRA_STATE_RINGING))
{
String phonenumber = bundle.getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
Log.i("IncomingCallReceiver","Incomng Number: " + phonenumber);
try{
search.open();
c = search.callinfo(phonenumber);
if(c != null){
int iFN = c.getColumnIndex("firstname");
int iLN = c.getColumnIndex("lastname");
String FN = c.getString(iFN);
String LN = c.getString(iLN);
caller = FN + " " + LN;
}
else{
caller = "Unknown";
}
search.close();
}
catch (Exception e){
Toast.makeText(context, "error"+e.toString(), Toast.LENGTH_LONG).show();
}
Toast.makeText(context, caller, Toast.LENGTH_LONG).show();
}
}
}
I don't think the problem lies with the methode ".callinfo()", nonetheless I posted it below:
public Cursor callinfo(String l) {
// TODO Auto-generated method stub
String[] columns = new String[]{"phonenumber", "homenumber"};
Cursor c = db.query("mycontacts", columns, "phonenumber = " + l + " OR " + "homenumber = " + l, null, null, null, null);
return c;
}
The Catch returns : errorandroid.database.CursorIndexOutOfBoundsException: Index -1 requested, with a size of 1.
Thank you in advance for any help you can give me.
Cheers

Because the initial cursor position is -1, try to use if(c.moveToNext()) instead of if(c != null).
