In Android how to fetch the contacts and save to database implements?

In Android how to fetch the contacts and save to database implements? - java

In My android program I have NumberList.java with list_layout.xml
In xml there is a edit text field,and a button ..in edit text we can enter a phone number and with the button we can save..
But my requirement is I want to fetch the number from contacts and save them through a button..MainActivity.java is the program which fetchs the selected contact number..But I cant save as like NumberList.java.
How can I implement???
NumberList.java
public class NumberList extends Activity implements OnClickListener{
private RemindersDbAdapter mDbAdapter;
private EditText numbr;
private Button btnAdd;
private Button btnTree;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.list_layout);
mDbAdapter=new RemindersDbAdapter(this);
mDbAdapter.open();
numbr=(EditText) findViewById(R.id.editNumber);
btnAdd=(Button) findViewById(R.id.btnSave);
btnAdd.setOnClickListener(this);
}
public void onClick(View v) {
switch (v.getId()) {
case R.id.btnSave:
if((numbr.getText().toString()!=null)&&(numbr.getText().toString().length()>=7))
{ mDbAdapter.createReminder(numbr.getText().toString(), "", "");
mDbAdapter.close();
finish();
}
else
{
Toast.makeText(getApplicationContext(), "plz enter correct number", Toast.LENGTH_SHORT).show();
}
default:
break;
}
}
#Override
protected void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
mDbAdapter.close();
}}
and the another one which fetchs the contacts number from contact list
MainActivity.java
public class MainActivity extends Activity {
Button buttonReadContact;
TextView textPhone;
EditText ed;
final int RQS_PICKCONTACT = 1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
buttonReadContact = (Button)findViewById(R.id.readcontact);
textPhone = (TextView)findViewById(R.id.phone);
ed = (EditText)findViewById(R.id.phno1);
buttonReadContact.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View arg0) {
//Start activity to get contact
final Uri uriContact = ContactsContract.Contacts.CONTENT_URI;
Intent intentPickContact = new Intent(Intent.ACTION_PICK, uriContact);
startActivityForResult(intentPickContact, RQS_PICKCONTACT);
}});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
if(resultCode == RESULT_OK){
if(requestCode == RQS_PICKCONTACT){
Uri returnUri = data.getData();
Cursor cursor = getContentResolver().query(returnUri, null, null, null, null);
if(cursor.moveToNext()){
int columnIndex_ID = cursor.getColumnIndex(ContactsContract.Contacts._ID);
String contactID = cursor.getString(columnIndex_ID);
int columnIndex_HASPHONENUMBER = cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER);
String stringHasPhoneNumber = cursor.getString(columnIndex_HASPHONENUMBER);
if(stringHasPhoneNumber.equalsIgnoreCase("1")){
Cursor cursorNum = getContentResolver().query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=" + contactID,
null,
null);
//Get the first phone number
if(cursorNum.moveToNext()){
int columnIndex_number = cursorNum.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
String stringNumber = cursorNum.getString(columnIndex_number);
ed.setText(stringNumber);
}
}else{
textPhone.setText("NO Phone Number");
}
}else{
Toast.makeText(getApplicationContext(), "NO data!", Toast.LENGTH_LONG).show();
}
}
}
}
}

this is what you need just create a table and with name and phone_no and fill db details in below code
btn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
readContacts(getApplicationContext());
}
});
public void readContacts(Context ctx, String no) {
ContentValues cvs cvs = new ContentValues();
Cursor phones = ctx.getContentResolver().query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null,
null, ContactsContract.Contacts.DISPLAY_NAME + " ASC");
if (phones.getCount() > 0) {
while (phones.moveToNext()) {
String phoneNumber = phones
.getString(phones
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
if (!TextUtils.isEmpty(phoneNumber)) {
String name = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
cvs.put("name", name );
cvs.put("phone_no", phoneNumber );
}
}
}
insertItem(cvs, "readtables");
}
private void insertItem(ContentValues cbs, String Tablename) {
SQLiteDatabase db = dbl.getWritableDatabase();
try {
CreateTablenew(Tablename);
db.insert("Tablename", null, cbs);
} catch (SQLException e) {
}
}

Sqlite Error On Android Application

Im trying to build an app that sets many alarm clocks and i want to save the alarms with an SQLite database. Already watched many tutorials for this but still having a problem using the database. Firstly i want to save the alarm one by one by pushing a button. I tried also to insert manually 2 alarms but it didnt worked either. What am i doing wrong? I am pretty new to this!

Retrieve contact from mobile's phone directory

This code can open a built-in contacts directory on a mobile device. However, when I select a contact, the app reports "done", but doesn't retrieve the contact number -- the user can't send a message.
How do I retrieve the contact number? List View is not a solution: I need to return just the one number, not extra information.
Here's my code:
public EditText no;
public EditText msg;
public Button cancel;
public Button snd;
public String Number,name,Message;
public int run=0;
public static final int PICK_CONTACT=1;
public void callContacts(View v)
{
Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
startActivityForResult(intent,PICK_CONTACT);
}
#Override
public void onActivityResult(int reqCode,int resultCode,Intent data)
{
super.onActivityResult(reqCode,resultCode,data);
if(reqCode==PICK_CONTACT)
{
if(resultCode== ActionBarActivity.RESULT_OK)
{
Uri contactData = data.getData();
Cursor c = getContentResolver().query(contactData,null,null,null,null);
if(c.moveToFirst())
{
name = c.getString(c.getColumnIndexOrThrow(ContactsContract.Contacts.CONTENT_URI.toString()));
Toast.makeText(this,"done",Toast.LENGTH_SHORT).show();
}
}
}
}
and here is the onCreate method
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_second);
no = (EditText)findViewById(R.id.num);
msg = (EditText)findViewById(R.id.sms);
cancel = (Button)findViewById(R.id.cancel);
snd = (Button)findViewById(R.id.snd);
no.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
msg.setText("");
no.setText("");
callContacts(null);
}
});
snd.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
Number = no.toString();
Message = msg.getText().toString();
SmsManager manager = SmsManager.getDefault();
ArrayList<String>long_sms = manager.divideMessage(Message);
manager.sendMultipartTextMessage(Number,null,long_sms,null,null);
Toast.makeText(getApplicationContext(),"Sent Successfully",Toast.LENGTH_SHORT).show();
}
});
}

Here is the code just for selecting one phone number from contact list. i found this code simplest. let me know if there is any problem.
start activity with pick intent on phone data type:
findViewById(R.id.choose_contact_button).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent pickContact = new Intent(Intent.ACTION_PICK, ContactsContract.CommonDataKinds.Phone.CONTENT_URI);
startActivityForResult(pickContact, PICK_CONTACT_REQUEST);
}
});
Now set onAcitivityResult();
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent){
switch (requestCode){
case PICK_CONTACT_REQUEST:
if (resultCode == RESULT_OK){
Uri contactUri = intent.getData();
Cursor nameCursor = getContentResolver().query(contactUri, null, null, null, null);
if (nameCursor.moveToFirst()){
String name = nameCursor.getString(nameCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String number = nameCursor.getString(nameCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
((EditText)findViewById(R.id.person_name)).setText(name);
((EditText)findViewById(R.id.enter_mobile)).setText(number);
nameCursor.close();
}
}
break;
}
}

Storing and retrieving user uploaded images in parse

I have successfully been able to store user entered information into parse, but I haven't figure out how to do store a user uploaded image that would be associated with the current user in parse, and to retrieve a user image at a later time.
To clarify this, below is the code I have used for my profile creation activity, an activity that is prompted after the user has signing using social media and responds to a series of questions like age, preferred name, and where those information are later updated in the parse database and added to the current user.
Also in the activity, the user is already able to upload a picture from their device, my issue now resolves around taking that uploaded picture and storing it on parse, and associating the image with the current user who has signing using their social media account - the social media integration is done through parse.
I have looked into the following guide, but is still greatly confused.
https://www.parse.com/docs/android_guide#files
Any assistance would be greatly appreciated.
Thanks in advance.

Also in the activity, the user is already able to upload a picture
from their device, my issue now resolves around taking that uploaded
picture and storing it on parse, and associating the image with the
current user who has signing using their social media account - the
social media integration is done through parse.
Read the docs on files and on the response type when a file is upload to parse.com
"media":{"__type":"File","name":"e580f231-...-picf1","url":"http://files.parse.com/..52d6-picf1"}
So, after POST on the file to parse, you have a logical FILE entity that you can then point to in another class.
In that other clase , you can also point to the user who created the FILE.
Class2 {"createdby" : pointer($user), "media" : pointer($file)}
With that, you have a separate class with 2 , pointer types ( toUser, toFile ) and the col headers on the data browser will show :
pointer<_User> for the user
file for the file

You need to wait for the file to finish saving before you add it to the user.
Try adding a completion block to your file.saveInBackground() call, and moving all the currentUser manipulation into that completion block.
