In Android, how to select a contact and display it in my application?

I am starting an android, I am creating an application in which, when a user presses a button, the contacts that are stored on the mobile device are displayed. When he selects a contact from this, I should get the selected name and contact number. I tried to use the code, but only the name of the selected contact is displayed, not the phone number.

public void readcontact(){
    try {
        Intent intent = new Intent(Intent.ACTION_PICK, Uri.parse("content://contacts/people"));
        startActivityForResult(intent, PICK_CONTACT);
    } catch (Exception e) {
            e.printStackTrace();
      }
}

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);
                startManagingCursor(c);
                if (c.moveToFirst()) {
                  String name = c.getString(c.getColumnIndexOrThrow(People.NAME));  
                  String number = c.getString(c.getColumnIndexOrThrow(People.NUMBER));
                  perrsonname.setText(name);
                  Toast.makeText(this,  name + " has number " + number, Toast.LENGTH_LONG).show();
                 }
           }
         break;
      }

  }

I even need an additional number (home, office, etc.) of the selected contacts, can someone help me with this. Suggestions on this subject are noticeable.

     phoneNo.setOnFocusChangeListener(new OnFocusChangeListener()
      {   public void onFocusChange(View v, boolean hasFocus) 
          {
             Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
             startActivityForResult(intent,PICK_CONTACT );//PICK_CONTACT is private static final int, so declare in activity class
       } });

The easiest way to find a contact with a phone number and show the display name and the selected phone number. See Also: A complete, executable example as a method .

private final static int PICK_CONTACT = 0;

private void pickContact() {
    Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);

    // Show only contacts with phone number. (Also forces user to choose ONE 
    // phone number for a contact that has several.)
    intent.setType(ContactsContract.CommonDataKinds.Phone.CONTENT_TYPE);

    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) {
                handleSelectedContact(data);
            }
            break;
    }
}

private void handleSelectedContact(Intent intent) {
    Uri contactUri = intent.getData();
    Cursor c = getContentResolver().query(contactUri, null, null, null, null);
    if (c.moveToFirst()) {
        String name = c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
        String selectedPhone = c.getString(c.getColumnIndex(ContactsContract.Contacts.Entity.DATA1));

        String message = String.format("Name %s, selected phone %s", name, selectedPhone);
        Snackbar.make(contentView, message, Snackbar.LENGTH_LONG).show();
    }
    c.close();
}
