[開發] 複選聯絡人

[meya (落寞之心)]

以往的獲取聯絡人方法，是直接叫出系統內建的activity，之後由使用者點選想要的聯絡
人，再傳回去，如下範例：

/*Uri uri = Uri.parse("content://contacts/people");
  Intent intent = new Intent(Intent.ACTION_PICK, uri);
  startActivityForResult(intent, PICK_CONTACT_SUBACTIVITY);*/

但是選完一個人之後，如果還要再選一個人，那就只能再叫出這個activity



下面這個範例實作出多選聯絡人activity，也就是說叫出自己所寫的activity後，可以一
次選擇多人，之後再傳回去：

(註：之所以不用ListActivity這個現成的Activity，是因為使用系統內建的東西限制太
多，無法加入我所想要的Button上去，所以這個程式裡面手動寫了一個類似ListActivity
的東西，將content provider內聯絡人資料對應在list上)



public class MultiContactBook extends Activity {

List<String> contactName = new ArrayList<String>();
List<String> contactPhone = new ArrayList<String>();
//ArrayList<String> contactEmail = new ArrayList<String>();

public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);

  // Load the display name for the specified person
  Cursor cursor = getContentResolver().query(Contacts.CONTENT_URI,
                new String[]{Contacts._ID, Contacts.DISPLAY_NAME,
                ContactsContract.Contacts.HAS_PHONE_NUMBER}, null, null, null);

  // Announce the phone number
  Cursor cursorPhone = null;

  // Announce the Email
  //Cursor cursorEmail = null;

  try {
    while(cursor.moveToNext())
    {
    // Load the phone number (if any).
    cursorPhone = getContentResolver().query(Phone.CONTENT_URI,
                                        new String[]{Phone.NUMBER},
                  Phone.CONTACT_ID + "=" + cursor.getString(0), null,
                  Phone.IS_SUPER_PRIMARY + " DESC");
    cursorPhone.moveToFirst();

    /*cursorEmail = getContentResolver().query(Email.CONTENT_URI ,
                   new String[]{"_id","data1","data2","data3"},
                   Phone.CONTACT_ID + "=" + cursor.getString(0) , null, null);
    */

    //預防電話號碼為空
    String HasPhone = cursor.getString(
            ursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));
      if(HasPhone.equals("1")){
        contactName.add(cursor.getString(1));
        contactPhone.add(cursorPhone.getString(0));


        /*while(cursorEmail.moveToNext()) {
            if(!cursorEmail.isNull(1)){
            int i = cursorEmail.getInt(0);
            String str = cursorEmail.getString(1);
            str = cursorEmail.getString(2);
            str = cursorEmail.getString(3);
            contactEmail.add(cursorEmail.getString(1));
            }
        }*/

      }
     }
    } finally {
        cursor.close();
        cursorPhone.close();
        //cursorEmail.close();
      }

               android.R.layout.simple_list_item_multiple_choice, contactName);
