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

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));

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");
}

I am working with an Android application which shows the list of contacts in the phone like Whats-app. I am successful with getting the contacts to the Application database. When I try to update my DB when a contact is newly added/edited/deleted using Content Observer, I mainly face two problems
1. When Calls ,
String contactName = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
I am getting wrong name. eg:- I edited Samuel's Contact no but checking the above code getting David's name.
when I try to get contact number by using the code,
contactNumber = cur.getString(cur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
I am getting error
E/CursorWindow: Failed to read row 0, column -1 from a CursorWindow which has 402 rows, 41 columns.

I have chat application in which I am sending message to numbers which are being sent successfully. Now I want that I should set start date time of message sending. for this purpose I have stored datetime in sqlite database. that is my code:
while (true) {
cursor = databaseHelperClass.getMessageNotSent();
if (cursor != null && cursor.moveToFirst()) {
do {
Id = cursor.getInt(cursor.getColumnIndex("ID"));
jobMessageNotSent = cursor.getString(cursor.getColumnIndex("Message"));
startDatetime = cursor.getString(cursor.getColumnIndex("StartDatetime"));
isComplete = cursor.getInt(cursor.getColumnIndex("isComplete"));
} while (cursor.moveToNext());
new SendJobMessages().execute(Id);
}
and this is my asyncTask code:
private class SendJobMessages extends AsyncTask<Integer , Integer, Integer> {
private String jobNumbers = null;
#Override
protected Integer doInBackground(Integer... jobMessageIds) {
totalNumbers = jobMessageIds.length;
jobNumbersArray = new ArrayList<String>();
databaseHelperClass = new DatabaseHelperClass(getApplicationContext());
cursor = databaseHelperClass.getMessagesNumber(Id);
if (cursor != null && cursor.moveToFirst()) {
do {
JobMessagesId = cursor.getInt(cursor.getColumnIndex("ID"));
laterJobsNumbers = cursor.getString(cursor.getColumnIndex("Numbers"));
JobId = cursor.getInt(cursor.getColumnIndex("JobId"));
jobNumbersArray.add(laterJobsNumbers);
} while (cursor.moveToNext());
// sendJobsMessages();
for (int i = 0; i < jobNumbersArray.size(); i++) {
jobNumbers = jobNumbersArray.get(i);
if (countMessagePerDay() >= Integer.parseInt(MaxNoOfMessagePerDay)) {
try {
Thread.sleep(10000);
} catch (InterruptedException e) {
e.printStackTrace();
}
} else {
try {
sendSMSLater(String.valueOf(jobNumbers));
} catch (ParseException e) {
e.printStackTrace();
}
this.publishProgress(1);
}
}
}
return jobMessageIds.length;
}
}
and this is my sqlite query:
public Cursor getJMessagesNotSent() {
db = this.getReadableDatabase();
String query = "select * from Jobs where iscomplete = 0 and datetime('now') > startdatetime";
Cursor cursor = db.rawQuery(query, null);
return cursor;
}
and for numbers:
public Cursor getJobsNumber(int jobId) {
db = this.getReadableDatabase();
String query = "SELECT * From JobMessages where issent = 0 and JobId = " + jobId + "";
Cursor cursor = db.rawQuery(query, null);
return cursor;
}
My app is taking forever to load,how can I use paging that's it would load me like 10-15 people in a page and not to take 2 minute to my app for loading??
this is my code:
thank's for the help
public class Contacts extends Util<Contact> {
public Contacts(Activity activity) {
super(activity);
}
#Override
public void init() {
list = getContactsBasic();
for (int i = 0; i < list.size(); i++) {
Contact current = list.get(i);
current.image = getContactImage(current.id);
if (current.hasPhone) {
current.phones = getContactPhones(current.id);
}
}
}
LinkedList<Contact> getContactsBasic() {
Uri contactsUri = android.provider.ContactsContract.Contacts.CONTENT_URI;
Cursor cursor = activity.getContentResolver().query(contactsUri, null, null, null, null);
LinkedList<Contact> list = new LinkedList<Contact>();
if (cursor != null) {
if (cursor.moveToFirst()) {
do {
int id = cursor.getInt(cursor.getColumnIndex(android.provider.ContactsContract.Contacts._ID));
String name = cursor.getString(cursor.getColumnIndex(android.provider.ContactsContract.Contacts.DISPLAY_NAME));
int hasPhone = cursor.getInt(cursor.getColumnIndex(android.provider.ContactsContract.Contacts.HAS_PHONE_NUMBER));
// add more columns here
boolean hasPhoneBoolean; //editor: or simply: boolean hasPhoneBoolean = (hasPhone == 1)
if (hasPhone == 1){
hasPhoneBoolean = true;
}
else {
hasPhoneBoolean = false;
}
Contact contact = new Contact(id, name, hasPhoneBoolean);
//Contact contact = new Contact(id, name, (hasPhone == 1) ? true : false);
list.add(contact);
}
while (cursor.moveToNext());
}
cursor.close();
}
return list;
}
LinkedList<Phone> getContactPhones(int id) {
Uri phonesUri = android.provider.ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
String filter = android.provider.ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = " + String.valueOf(id);
Cursor cursor = activity.getContentResolver().query(phonesUri, null, filter, null, null);
LinkedList<Phone> list = new LinkedList<Phone>();
if (cursor != null) {
if (cursor.moveToFirst()) {
do {
String number = cursor.getString(cursor.getColumnIndex(android.provider.ContactsContract.CommonDataKinds.Phone.NUMBER));
int type = cursor.getInt(cursor.getColumnIndex(android.provider.ContactsContract.CommonDataKinds.Phone.TYPE));
Phone phone = new Phone(number, type);
list.add(phone);
}
while (cursor.moveToNext());
}
Change
Cursor cursor = activity.getContentResolver().query(contactsUri, null, null, null, null);
to
Cursor cursor = activity.getContentResolver().query(contactsUri, null, null, null, "ASC LIMIT " + HOW_MANY_ROWS_YOU_NEED);
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() {

{
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);

I have two buttons inside of my application, one for next and one for prev. I want the next button to get the next record inside of my database and display it inside of my view, and the prev button to get the previous record and display it inside of my view. How would I call the next or previous record? I have looked for tutorials and stuff but didn't find any. I anyone has a tutorial please share with me. Thanks for any help. I wish I had some code to provide but I really don't know where to start.
I use an int to pull the record from the dbase.
From my ContactView class
static long record = 1;
public void getData() {
DBase db = new DBase(this);
db.open();
lastRecord = db.lRec();
firstRecord = db.fRec();
rRec = db.getRec(record);
db.close();
}
then my query is from my Dbase class
public String[] getRec(long record) {
record = ContactView.record;
String[] columns = new String[] { KEY_ROWID, KEY_ONE, KEY_TWO,
KEY_THREE, KEY_FOUR, KEY_FIVE, KEY_SIX };
Cursor c = ourDatabase.query(DATABASE_TABLE, columns, KEY_ROWID + "="
+ record, null, null, null, null);
if (c != null && c.moveToFirst()) {
String rRec = c.getString(0);
String rOne = c.getString(1);
String rTwo = c.getString(2);
String rThree = c.getString(3);
String rFour = c.getString(4);
String rFive = c.getString(5);
String rSix = c.getString(6);
String[] rData = { rRec, rOne, rTwo, rThree, rFour,
rFive, rSix };
return rData;
}
return null;
}
and the next few are from my ContactView class
my buttons
#Override
public void onClick(View arg0) {
switch (arg0.getId()) {
case R.id.bSQLvPrev:
recordMinus();
display();
break;
case R.id.bSQLvNext:
recordPlus();
display();
break;
}
}
and the methods they call
public void display() {
etSQLvRec.setText(rRec[0]);
etSQLvOne.setText(rRec[1]);
etSQLvTwo.setText(rRec[2]);
etSQLvThree.setText(rRec[3]);
etSQLvFour.setText(rRec[4]);
etSQLvFive.setText(rRec[5]);
etSQLvSix.setText(rRec[6]);
}
public void recordPlus() {
record++;
}
public void recordMinus() {
record--;
}
That will get the record from the database based on the "record" variable, and the buttons increment it, or decrement it, it also skips any "empty" records.
EDIT OK, I had changed some stuff around since I lasted used my db, so use the next recordPlus() and recordMinus() code instead
public void recordPlus() {
if (record < lastRecord) {
record++;
} else {
record = firstRecord;
}
getData();
do {
if (record < lastRecord) {
record++;
} else {
record = firstRecord;
}
getData();
} while (rRec == null);
}
public void recordMinus() {
if (record == 1) {
record = lastRecord;
} else {
record--;
}
getData();
do {
if (record == 1) {
record = lastRecord;
} else {
record--;
}
getData();
} while (rRec == null);
}
And you'll need my fRec() and lRec() which find the first and last records in the DB
public long fRec() {
Cursor c = ourDatabase.query(DATABASE_TABLE, new String[] { "min(" +
KEY_ROWID
+ ")" }, null, null, null, null, null);
c.moveToFirst();
long rowID = c.getInt(0);
return rowID;
}
}
public long lRec() {
long lastRec = 0;
String query = "SELECT ROWID from Table order by ROWID DESC limit 1";
Cursor c = ourDatabase.rawQuery(query, null);
if (c != null && c.moveToFirst()) {
lastRec = c.getLong(0);
}
return lastRec;
}
