Android调用系统选择联系人，适合更多种手机,Google官方推荐

跳转到系统联系人选择界面，获取相应联系人信息

调用方式：

Intent i = new Intent();
i.setAction(Intent.ACTION_PICK);
i.setData(ContactsContract.Contacts.CONTENT_URI);
startActivityForResult(i, 1);

下面是onActivityResult(int requestCode, int resultCode, Intent data) 

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        String name = "";
        String phoneNumber = "";
        switch (resultCode) {
        case RESULT_OK:
            switch (requestCode) {
            case 1:
                if (data == null) {
                    return;
                }
                Uri contactData = data.getData();
                if (contactData == null) {
                    return;
                }
                Cursor cursor = managedQuery(contactData, null, null, null,
                        null);
                if (cursor.moveToFirst()) {
                    name = cursor
                            .getString(cursor
                                    .getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
                    String hasPhone = cursor
                            .getString(cursor
                                    .getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));
                    String id = cursor.getString(cursor
                            .getColumnIndex(ContactsContract.Contacts._ID));
                    if (hasPhone.equalsIgnoreCase("1")) {
                        hasPhone = "true";
                    } else {
                        hasPhone = "false";
                    }
                    if (Boolean.parseBoolean(hasPhone)) {
                        Cursor phones = getContentResolver()
                                .query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
                                        null,
                                        ContactsContract.CommonDataKinds.Phone.CONTACT_ID
                                                + " = " + id, null, null);
                        while (phones.moveToNext()) {
                            phoneNumber = phones
                                    .getString(phones
                                            .getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                        }
                        phones.close();
                    }

                    cursor.close();
                }
                phoneNumber = phoneNumberFormat(phoneNumber);
                Log.i("info", "联系人："+ name + "--"
                        + phoneNumberFormat(phoneNumber));
                             
                break;
            }
            break;
        }
        super.onActivityResult(requestCode, resultCode, data);
    }

Google官方文档是这样写的：

private void pickContact() {
    // Create an intent to "pick" a contact, as defined by the content provider URI
    Intent intent = new Intent(Intent.ACTION_PICK, Contacts.CONTENT_URI);
    startActivityForResult(intent, PICK_CONTACT_REQUEST);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    // If the request went well (OK) and the request was PICK_CONTACT_REQUEST
    if (resultCode == Activity.RESULT_OK && requestCode == PICK_CONTACT_REQUEST) {
        // Perform a query to the contact's content provider for the contact's name
        Cursor cursor = getContentResolver().query(data.getData(),
        new String[] {Contacts.DISPLAY_NAME}, null, null, null);
        if (cursor.moveToFirst()) { // True if the cursor is not empty
            int columnIndex = cursor.getColumnIndex(Contacts.DISPLAY_NAME);
            String name = cursor.getString(columnIndex);
            // Do something with the selected contact's name...
        }
    }
}
