Question

public class ImportContactsActivity extends Activity {
/** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.contact);
        TextView txt = (TextView)findViewById(R.id.con);
        String msg = "";

        ContentResolver cr = getContentResolver();
        Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
        while (cursor.moveToNext()) {
                String name = cursor.getString(cursor.getColumnIndexOrThrow(People.NAME));
                String number = cursor.getString(cursor.getColumnIndexOrThrow(People.NUMBER));
                String email = cursor.getString(cursor.getColumnIndexOrThrow(People.PRIMARY_EMAIL_ID));

                msg += name + " " + number + " " + email + "\n";
        }
        txt.setText(msg.toString());
    }
}

我正在开发一个应用程序，其中应用程序能够发送包含所有当前电话联系人（姓名+电话号码）的电子邮件作为备用替代方案。我正在尝试如何提取所有手机联系人信息并在TextView上显示它们......但我不能这样做，有人请咨询我。感谢...

使用ContactsContract.CommonDataKinds.Phone.CONTENT_URI代替ContactsContract.Contacts.CONTENT_URI，以便您可以获取电话号码，并更改这些行

String name = cursor.getString(cursor.getColumnIndexOrThrow(People.NAME));
String number = cursor.getString(cursor.getColumnIndexOrThrow(People.NUMBER));
String email = cursor.getString(cursor.getColumnIndexOrThrow(People.PRIMARY_EMAIL_ID));

到

String name = cursor.getString(cursor.getColumnIndexOrThrow(Phone.DISPLAY_NAME));
String number = cursor.getString(cursor.getColumnIndexOrThrow(Phone.NUMBER));

您需要另一个查询来获取email_id。从第一个光标，您可以获得联系人ID，如此

long contactId = cursor.getLong(cursor.getColumnIndexOrThrow(Phone.CONTACT_ID));

现在使用过滤器中的contactId查询电子邮件uri

long emailId;
Cursor cur = getContentResolver()
                    .query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,
                     new String[]{"_id"},
                     "contact_id = " + contactId,
                     null,null);
if(cur != null && cur.moveToFirst()){
    emailId = cur.getLong(0);
}

如何在textView或String中显示所有手机通讯录（姓名，电话号码）？
