Доступ к контактам в телефонной книге для SMS-сообщений?

Question

Итак, у меня есть мой класс сообщений SMS. Тем не менее, мне бы хотелось, чтобы пользователь нажал на edittext для ввода номера телефона ... телефонная книга телефона загрузилась, и пользователь может выбрать один или несколько контактов, а SMS отправится ко всем выбранным контактам. Как загрузить и выбрать контакты с помощью телефонной книги для моего SMS?

я немного застрял я мог получить объяснение, пожалуйста :)

Класс:

Button btnSendSMS; 
    EditText txtPhoneNo; 
    EditText txtMessage; 

    private static final int ACTION_PICK_CONTACT=1; 

    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) 
    { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_send_sms); 
     btnSendSMS = (Button) findViewById(R.id.btnSendSMS); 
     txtPhoneNo = (EditText) findViewById(R.id.txtPhoneNo); 
     txtMessage = (EditText) findViewById(R.id.txtMessage); 

     txtPhoneNo.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      Intent i = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI); 
      startActivityForResult(i, ACTION_PICK_CONTACT); 
      } 
     }); 


     btnSendSMS.setOnClickListener(new View.OnClickListener() 
     { 
      public void onClick(View v) 
      { 
       String phoneNo = txtPhoneNo.getText().toString(); 
       String message = txtMessage.getText().toString() + displayLocation(); 
       displayLocation(); 

       if (phoneNo.length()>0 && message.length()>0) 
        sendSMS(phoneNo, message); 
       else 
        Toast.makeText(getBaseContext(), 
          "Please enter both phone number and message.", 
          Toast.LENGTH_SHORT).show(); 
      } 
     }); 


    } 


    public void onActivityResult(int reqCode, int resCode, Intent data) { 
     super.onActivityResult(reqCode, resCode, data); 

     switch (reqCode) {

        }

Используйте это так:

int ACTION_PICK_CONTACT=1; 

//Call this in your onclick event 
Intent i = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI); 
startActivityForResult(i, ACTION_PICK_CONTACT); 

//This is called when user has selected a contact 
public void onActivityResult(int reqCode, int resCode, Intent data) { 
    super.onActivityResult(reqCode, resultCode, data); 

    switch (reqCode) { 
    case (ACTION_PICK_CONTACT) : 
     if (resCode == Activity.RESULT_OK) { 

      Uri contact = data.getData(); 
      Cursor cursor = managedQuery(contact, null, null, null, null); 
      if (cursor.moveToFirst()) { 
      String contact_id =cursor.getString(c.getColumnIndexOrThrow(ContactsContract.Contacts._ID)); 

      Cursor phoneCursor = getContentResolver().query( 
        ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null, 
        ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contact_id, 
        null, null); 
      phoneCursor.moveToFirst(); 
      String phoneNumber = phoneCursor.getString(phoneCursor.getColumnIndex("data1")); //THE NUMBER TO SEND YOUR SMS 
      txtPhoneNo.setText(phoneNumber); 
      } 
     } 
     break; 
    } 
}
