मेरे एंड्रॉइड प्रोग्राम में संपर्कों का उपयोग कैसे करें

Question

मैं एक टेक्स्ट संदेश एप्लिकेशन बना रहा हूं और अपने एंड्रॉइड एप्लिकेशन में संपर्कों को एक्सेस करना चाहता हूं।

मैं संपर्कों को एक्सेस करना चाहता हूं जैसे कि वे वास्तविक संपर्क सूची में हैं। चयनित होने पर मुझे अपनी गतिविधि पर वापस लौटना होगा जिसमें मैं उस व्यक्ति को एक एसएमएस भेज सकता हूं। या डेटाबेस को एक्सेस करना संभव है जिसमें संपर्क संग्रहीत किए जाते हैं?

मेरे कोड नीचे दिखाया गया है:

किसी को भी मेरी मदद कर सकते:

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)); 

मेरे LogCat इस तरह दिखता है?

Answer 1

उपयोग इस कोड को संपर्क चुनने के लिए:

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); 
      } 
     } 
     } 
    } 
    }

इस कोड का प्रयास करें। यह 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){} 
} 

में सभी संपर्कों को संग्रहीत करता है यदि आप विशिष्ट संपर्क का उपयोग किसी शर्त पर संग्रहीत करना चाहते हैं।
