获取安卓联系人

Question

我正在尝试获取所有联系人及其电子邮件地址的列表。

目前我正在使用此代码，但是我得到了许多重复的名称和电子邮件。我想要的是只有一个人和一个电子邮件。是否有一种方法可以在查询联系人时合并它们？

同时，我只需要一个大于2.0版本的解决方案。

    private void init() {

    ContentResolver cr = getContentResolver();
    Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,null, null, null, null);
    if (cur.getCount() > 0) {
    while (cur.moveToNext()) {
        String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
    String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
        Cursor emailCur = cr.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,null,ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?", new String[]{id},null); 
        while (emailCur.moveToNext()) { 
                String email = emailCur.getString( emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
                Log.e("Email",name+" "+email);
            } 
            emailCur.close();
        }

    }

我真正想做的是构建一个多联系人选择器，这样用户就可以选择多个人进行电子邮件发送。但我会查看那个链接，看看是否有可以学习的代码。谢谢！ - Faisal Abid

@Faisal，我在互联网上看到了很多多重联系人选择器。在这个网站上也是如此。至于你的问题，根据你的数据库查询，你正在打印出相同名称的多个电子邮件。请再次检查你的代码。 - Reno

我没有明确的问题。你说的“我得到了很多重复的姓名和电子邮件”是什么意思？通过上述代码，您必须获取联系人的显示名称及其相应的邮件ID。您要进行什么修改？ - Manish Khot

哦，我有那样的时刻。上面的代码我是从网上一个源复制过来的，我只看了第二个循环，没看第一个。不管怎样，感谢大家帮助我意识到这个问题！ - Faisal Abid

尝试使用下面的工作代码。

public class dddddddddd extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
       // setContentView(R.layout.main);
        readContacts();
    }

    public void readContacts(){
         ContentResolver cr = getContentResolver();
         Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,null, null, null, null);

         if (cur.getCount() > 0) {
            while (cur.moveToNext()) {
                String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
                String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
                if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
                    System.out.println("name : " + name + ", ID : " + id);

                    // get the phone number
                    Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,
                                           ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?",
                                           new String[]{id}, null);
                    while (pCur.moveToNext()) {
                          String phone = pCur.getString(
                                 pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                          System.out.println("phone" + phone);
                    }
                    pCur.close();

                    while (emailCur.moveToNext()) {
                        // This would allow you get several email addresses
