无法获取本地电话联系人姓名、手机号码和电子邮件地址

Question

在我的应用程序中，我想获取并列出联系人姓名和他们的号码，我尝试过电子邮件地址，但ContactsContract.CommonDataKinds.Email和ContactsContract.Contacts.DISPLAY_NAME冲突，所以如果可能的话，无法友好地获取。请提供我尝试过的一些代码，如下代码

    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) {
                 Cursor pCur = cr.query(
                         ContactsContract.CommonDataKinds.Phone.CONTENT_URI, 
                         null, 
                         ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?", 
                         new String[]{id}, null);
                 while (pCur.moveToNext()) {
                     String phoneNo = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                     Toast.makeText(NativeContentProvider.this, "Name: " + name + ", Phone No: " + phoneNo, Toast.LENGTH_SHORT).show();
                 } 
            pCur.close();
        }
        }
    }
    String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
    Cursor emailCur = cr.query(
            ContactsContract.CommonDataKinds.Email.CONTENT_URI,
            null,
            ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?",
            new String[]{id}, null);
    while (emailCur.moveToNext()) {
        // This would allow you get several email addresses
            // if the email addresses were stored in an array
        String email = emailCur.getString(
                      emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
        String emailType = emailCur.getString(
                      emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.TYPE));
      System.out.println("Email " + email + " Email Type : " + emailType);
    }
    emailCur.close();

Answer 1

您的代码的问题可能是您想要的应该在两个单独的查询中。

查询电子邮件帐户或电话号码列表使用常量，如ContactsContract.CommonDataKinds中的常量，URI:Contract.Common_DataKinds.email.CONTENT_URI.

查询不是列表（如名称）的实际联系人属性将使用ContactsContract.Contact.Contracts中的常量。URI:基于从Contacts.CONTENT_URI.返回的数据

信息并不是都存储在同一个地方，这可能就是为什么会发生冲突的原因。
