come accedere ai contatti nel mio programma Android

Question

Sto facendo un'applicazione di messaggi di testo e voglio accedere ai contatti nella mia applicazione Android .

Desidero accedere ai contatti come se fossero nella lista dei contatti effettiva. Quando selezionato, ho bisogno di tornare alla mia attività in cui posso inviare un SMS a quella persona. O è possibile accedere al database in cui sono memorizzati i contatti?

Il mio codice è il seguente:

String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID)); 
String name = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME)); 
String no = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Phone.NUMBER)); 

mio LogCat assomiglia a questo:

Answer 1

uso di questo codice per prendere contatto:

Button button = (Button)findViewById(R.id.pickcontact); 

    button.setOnClickListener(new OnClickListener() 
     { 
      @Override 
      public void onClick(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); 

    switch(reqCode) 
    { 
     case (PICK_CONTACT): 
     if (resultCode == Activity.RESULT_OK) 
     { 
      Uri contactData = data.getData(); 
      Cursor c = managedQuery(contactData, null, null, null, null); 
      if (c.moveToFirst()) 
      { 
      String id = c.getString(c.getColumnIndexOrThrow(ContactsContract.Contacts._ID)); 

      String hasPhone = 
      c.getString(c.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)); 

      if (hasPhone.equalsIgnoreCase("1")) 
      { 
     Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null, 
      ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ id,null, null); 
      phones.moveToFirst(); 
      String cNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); 
      // Toast.makeText(getApplicationContext(), cNumber, Toast.LENGTH_SHORT).show(); 
      setCn(cNumber); 
      } 
     } 
     } 
    } 
    }

Answer 3

provare questo codice. memorizza tutti i contatti in ArrayList

ArrayList<HashMap<String,String>> contactData=new ArrayList<HashMap<String,String>>(); 
ContentResolver cr = getContentResolver(); 
Cursor cursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,null, null, null, null); 
while (cursor.moveToNext()) { 
    try{ 
    String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID)); 
    String name=cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)); 
    String hasPhone = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)); 
    if (Integer.parseInt(cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) { 
     Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId, null, null); 
     while (phones.moveToNext()) { 
      String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); 
      HashMap<String,String> map=new HashMap<String,String>(); 
      map.put("name", name); 
      map.put("number", phoneNumber); 
      contactData.add(map); 
     } 
     phones.close(); 
    } 
}catch(Exception e){} 
} 

se si desidera memorizzare il contatto specifico utilizzare la condizione if.
