如何获取所有联系人及其所有属性

Question

有没有人知道一种简便的方法，可以获取安卓设备上保存的所有联系人及其属性（姓名、电话、电子邮件等）？

我需要一种适用于Android 1.5到4.0的解决方案。

非常感谢。

要获取名称和数字，请使用以下代码：

private void getNameNumber(){
        Uri uri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
        ContentResolver cr = getContentResolver();
        Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,null, null, null, null);
        String[] projection    = new String[] {ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME,
                        ContactsContract.CommonDataKinds.Phone.NUMBER };
        Cursor names = getContentResolver().query(uri, projection, null, null, null);

        int indexName = names.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME);
        int indexNumber = names.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
        names.moveToFirst();
        do {

            String name   = names.getString(indexName);
            Log.e("Name new:", name);
            String number = names.getString(indexNumber);
            Log.e("Number new:","::"+number);

        } while (names.moveToNext());
    }

要获取所有细节，请使用以下代码并根据您的要求进行修改。

private void getDetails(){
        Uri uri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
        ContentResolver cr = getContentResolver();
        Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,null, null, null, null);
            String[] projection    = new String[] {ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME,
                        ContactsContract.CommonDataKinds.Phone.NUMBER ,ContactsContract.CommonDataKinds.Email.DATA };
        Cursor names = getContentResolver().query(uri, projection, null, null, null);

        int indexName = names.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME);
        int indexNumber = names.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
        names.moveToFirst();
        do {

            String name   = names.getString(indexName);
            Log.e("Name new:", name);
            String number = names.getString(indexNumber);
            Log.e("Number new:","::"+number);

        } while (names.moveToNext());
        // email


            while (cur.moveToNext()) {
                String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
                Cursor email = cr.query( 
                        ContactsContract.CommonDataKinds.Email.CONTENT_URI, null,
                        ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?", 
                                new String[]{id}, null); 
                while (email.moveToNext()) { 
                    //to get the contact names
                    // if the email addresses were stored in an array
                    String emailid = email.getString(email.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
                    Log.e("Email id ::", emailid);
                    String emailType = email.getString(email.getColumnIndex(ContactsContract.CommonDataKinds.Email.TYPE)); 
                    Log.e("Email Type ::", emailType);

                } 
                email.close();
            }


        //address
            while (cur.moveToNext()) {
            String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
            Cursor addrCur = cr.query(ContactsContract.CommonDataKinds.StructuredPostal.CONTENT_URI,null,
                    ContactsContract.CommonDataKinds.StructuredPostal.CONTACT_ID+ " = ?",
                    new String[] { id },null);
            while(addrCur.moveToNext()) {
                String street = addrCur.getString(addrCur.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.STREET));
                Log.e("Street ::", street);
                String city = addrCur.getString(addrCur.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.CITY));
                Log.e("City ::", city);
                String state = addrCur.getString(addrCur.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.REGION));
                Log.e("State ::", state);
                String postalCode = addrCur.getString(addrCur.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.POSTCODE));
                Log.e("Postal Code ::", postalCode);
            } 
            addrCur.close();

        }
    }

谢谢你的代码。它很好地运行了。但是我无法获取地址详细信息。即使它也无法在logcat中打印。请帮帮我。 - AndroidRaji

退出电子邮件循环时，cur为空。您应该在电子邮件循环内使用地址查询。 - user2362956

如果电子邮件地址与姓名匹配会更好，但它们以单独的列表形式出现。 - DragonFire
