I'm trying to build a graph in achartengine with data from my SQLite database. Getting the data from the database works, but it does always build just one point and not a graph. What am I doing wrong?
Here is my code:
public String getValue1(long l) {
String[] columns = new String[]{ KEY_Value1, KEY_Value2 };
Cursor c = Database.query(DATABASE_TABLE, columns, KEY_ROWID + "=" + l, null, null, null, null);
if (c != null){
c.moveToFirst();
String value1 = c.getString(0);
return value1;
}
return null;
}
public String getValue2(long l) {
String[] columns = new String[]{ KEY_Value1, KEY_Value2 };
Cursor c = Database.query(DATABASE_TABLE, columns, KEY_ROWID + "=" + l, null, null, null, null);
if (c != null){
c.moveToFirst();
String value2 = c.getString(1);
return value2;
}
return null;
}
DB getData = new DB(this);
getData.open();
for (int i = 1; value1 == null; i++) {
Stirng value1 = getData.getValue1(i);
String value2 = getData.getValue2(i);
}
getData.close();
x = Double.parseDouble(value1);
y = Double.parseDouble(value2);
mCurrentSeries.add(x, y);
if (mChartView != null) {
mChartView.repaint();
}
}
Edit the second part to this code:
DB getData = new DB(this);
getData.open();
for (int i = 1; value1 == null; i++) {
String value1 = getData.getValue1(i);
String value2 = getData.getValue2(i);
x = Double.parseDouble(value1);
y = Double.parseDouble(value2);
mCurrentSeries.add(x, y); //*** this has to be inside the loop in order to draw more than one point ***
}
getData.close();
if (mChartView != null) {
mChartView.repaint();
}
}

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.

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 got name and contact id from android "my" contact by using this method
String[] columnNames = new String[] { Phone._ID,
Phone.DISPLAY_NAME };
Cursor c = LoginActivity.this.getContentResolver().query(
ContactsContract.Profile.CONTENT_URI, columnNames,
null, null, null);
int count = c.getCount();
boolean b = c.moveToFirst();
int position = c.getPosition();
if (count == 1 && position == 0) {
for (int j = 0; j < columnNames.length; j++) {
contact_id = c.getString(0);
namee = c.getString(1);
}
}
How to get phone number of the device too?
Add following permission in manifest.
<uses-permission android:name="android.permission.READ_CONTACTS" />
Use Following code to get "Me" contact.
public Loader<Cursor> onCreateLoader(int id, Bundle arguments) {
return new CursorLoader(this,
// Retrieve data rows for the device user's 'profile' contact.
Uri.withAppendedPath( ContactsContract.Profile.CONTENT_URI,ContactsContract.Contacts.Data.CONTENT_DIRECTORY),
ProfileQuery.PROJECTION,
//Don't select anything here null will return all available fields
null,
null,
null);
}
#Override
public void onLoadFinished(Loader<Cursor> cursorLoader, Cursor cursor) {
ArrayList<String> DataArray = new ArrayList<String>();
cursor.moveToFirst();
while (!cursor.isAfterLast()) {
//here where you get your data and its type
TypeName=cursor.getString(ProfileQuery.ADDRESS);//this will give you field name
Data=cursor.getString(ProfileQuery.NUMBER);//this will give you field data
cursor.moveToNext();
}
}
#Override
public void onLoaderReset(Loader<Cursor> cursorLoader) {
}
private interface ProfileQuery {
String[] PROJECTION = {
ContactsContract.Contacts.Data.MIMETYPE,
ContactsContract.CommonDataKinds.Email.ADDRESS ,
ContactsContract.CommonDataKinds.Email.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Organization.DATA3,
};
int ADDRESS = 0;
int NUMBER = 1;
}
Try this:
Cursor cursor = null;
try {
cursor = context.getContentResolver().query(Phone.CONTENT_URI, null, null, null, null);
int contactIdIdx = cursor.getColumnIndex(Phone._ID);
int nameIdx = cursor.getColumnIndex(Phone.DISPLAY_NAME);
int phoneNumberIdx = cursor.getColumnIndex(Phone.NUMBER);
int photoIdIdx = cursor.getColumnIndex(Phone.PHOTO_ID);
cursor.moveToFirst();
do {
String idContact = cursor.getString(contactIdIdx);
String name = cursor.getString(nameIdx);
String phoneNumber = cursor.getString(phoneNumberIdx);
} while (cursor.moveToNext());
} catch (Exception e) {
e.printStackTrace();
} finally {
if (cursor != null) {
cursor.close();
}
}
And in manifest:
<uses-permission android:name="android.permission.READ_CONTACTS" />
This is the proper way of doing it
1) call the intent
Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
if(intent.resolveActivity(getActivity().getPackageManager()) != null) {
getParentFragment().startActivityForResult(intent, CONTACT_REQUEST_CODE);
}
2) Implement onActivityResult
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == Activity.RESULT_OK) {
if (requestCode == CONTACT_REQUEST_CODE) {
uriContact = data.getData();
// replaceAll("\\D", "") : Remove everything that is not a digit
String number = retrieveContactNumber();
if (Connectivity.isConnected(getActivity())) {
if (number != null) {
String contact_number = number.replaceAll("\\D", "");
}
}
}
}
}
3) implement retrieveContactNumber()
private String retrieveContactNumber() {
String contactNumber = null;
// getting contacts ID
Cursor cursorID = getActivity().getContentResolver().query(uriContact,
new String[]{ContactsContract.Contacts._ID},
null, null, null);
if (cursorID.moveToFirst()) {
contactID = cursorID.getString(cursorID.getColumnIndex(ContactsContract.Contacts._ID));
}
cursorID.close();
// Using the contact ID to get contact phone number
Cursor cursorPhone = getActivity().getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
new String[]{ContactsContract.CommonDataKinds.Phone.NUMBER},
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ? AND " +
ContactsContract.CommonDataKinds.Phone.TYPE + " = " +
ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE,
new String[]{contactID},
null);
if (cursorPhone.moveToFirst()) {
contactNumber = cursorPhone.getString(cursorPhone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
}
cursorPhone.close();
return contactNumber;
}
4) Enjoy :)
Try this...
String[] columnNames = new String[] { Phone._ID,
Phone.DISPLAY_NAME };
Cursor c = LoginActivity.this.getContentResolver().query(
ContactsContract.Profile.CONTENT_URI, columnNames,
null, null, null);
int count = c.getCount();
boolean b = c.moveToFirst();
int position = c.getPosition();
if (count == 1 && position == 0) {
for (int j = 0; j < columnNames.length; j++) {
contact_id = c.getString(0);
namee = c.getString(1);
if(Integer.parseInt(c.getString(c.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID+ " = ?",new String[] { contact_id }, null);
while (pCur.moveToNext()) {
String noo = pCur.getString(pCur.getColumnIndex(CommonDataKinds.Phone.NUMBER));
}
}
}
}
I think you should use ContactsContract.CommonDataKinds.Phone.CONTENT_URI and there is column called ContactsContract.CommonDataKinds.Phone.NUMBER using which you may get contact number.
Have a look this code
public ArrayList<String> getContactList(){
ArrayList<String> list= new ArrayList<String>();
Uri uri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
String[] columns = new String[] {ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Phone.NUMBER};
Cursor people = getContentResolver().query(uri, columns, null, null, null);
int _nameIndex = people.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME);
int _numberIndex = people.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
people.moveToFirst();
do {
String name = people.getString(_nameIndex);
String number = people.getString(_numberIndex);
list.add(name+" :"+number);
// Do work...
} while (people.moveToNext());
return list;
}
This worked for me.
String[] columnNames = new String[] { Phone._ID,
Phone.DISPLAY_NAME, Phone.NUMBER };
Cursor c = LoginActivity.this.getContentResolver().query(
ContactsContract.Profile.CONTENT_URI, columnNames,
null, null, null);
int count = c.getCount();
boolean b = c.moveToFirst();
int position = c.getPosition();
if (count == 1 && position == 0) {
for (int j = 0; j < columnNames.length; j++) {
contact_id = c.getString(0);
name = c.getString(1);
number= c.getString(2);
}
}
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 {

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);
public Cursor getsomething()
{
this.open();
Cursor c = database.rawQuery("SELECT content_id FROM " +
DatabaseHandler.Table_Name2 +
" where playlist_id==100813", null);
if (c != null ) {
if (c.moveToFirst()) {
do {
String path = c.getString(c.getColumnIndex("content_id"));
MainActivity.t1.append("\n");
MainActivity.t1.append(path);
}while (c.moveToNext());
}
}
this.close();
return null;
}
I am using the above code to get the values but it is showing all the values from he content_id column. What am I doing wrong?
this.open();
ContentValues values2 = new ContentValues();
String csvFilename = "/mnt/sdcard/playlist.csv";
CSVReader csvReader = new CSVReader(new FileReader(csvFilename));
String Rowst[] = null;
while((Rowst = csvReader.readNext()) != null) {

database.insert(DatabaseHandler.Table_Name2, null, values2);
}
csvReader.close();
this.close();
this is my code to insert data in the this table,i am trying to read a csvfile on the sdcard and entering its data into table am i doing something wrong i have posted this also if it helps
public Cursor getsomething()
{
this.open();
Cursor c = db.query(DatabaseHandler.Table_Name2, null, "playlist_id=100813", null, null, null, null);
if (c.getCount() > 0)
{
if (c.moveToFirst())
{
do {
String path = c.getString(c.getColumnIndex("content_id"));
MainActivity.t1.append("\n");
MainActivity.t1.append(path);
}while (c.moveToNext());
}
}
this.close();
return null;
}
Cursor c = getContentResolver().query(CallLog.Calls.CONTENT_URI, null, null, null, null);
for (int i = 0; i < c.getColumnCount(); i++) {
Log.i(getClass().getName(), "retrieveCall(): " + c.getColumnName(i));
}
I can get all colume names in 4.0.x, but only got _id under 4.0.x. What 's the matter with my code? Thx in advance!
Cursor c = getContentResolver().query(CallLog.Calls.CONTENT_URI, null, null, null, null);
for (int i = 0; i < c.getColumnCount(); i++) {
Log.i(getClass().getName(), "retrieveCall(): " + c.getColumnName(i));
}
while (c.moveToNext()) {
for (int i = 0; i < c.getColumnCount(); i++) {
Log.i(getClass().getName(), "retrieveCall(): " + c.getColumnName(i) + " = " + c.getInt(i) + "/" + c.getString(i));
} ...
code above works well in 4.0.x, I guess there are some differences of database?
#Anuļ¼ this is my complete code, please kindly tell me if you found somthing wrong:
private void retrieveCall()
{
Cursor c = getContentResolver().query(CallLog.Calls.CONTENT_URI, null, null, null, null);
if (c != null) {
while (c.moveToNext()) {
String number = c.getString(c.getColumnIndex("number"));
String name = c.getString(c.getColumnIndex("name"));
long date = c.getLong(c.getColumnIndex("date"));
if (number.length() > 0) {
LogDetail log = null;
if (_callTable.containsKey(number)) {
log = (LogDetail) _callTable.get(number);
log.name = name;
log.date = date;
log.amount++;
} else {
log = new LogDetail();
log.name = name;
log.date = date;
log.amount = 1;
}
_callTable.put(number, log);
}
}
c.close();
}
}
try this ..... It worked for me...
Cursor c1 = getContentResolver().query(CallLog.Calls.CONTENT_URI,null,null,null,null);
for(int i=0;i<c1.getColumnCount();i++){
Log.i("Column name", ""+c1.getColumnName(i));
}
Don't forget to move the position of the Cursor
Use:
Cursor c = getContentResolver().query(CallLog.Calls.CONTENT_URI, null, null, null, null);
while (c.moveToNext()) {
Log.i(getClass().getName(), "retrieveCall(): " + c.getColumnName(i));
}
