在我自己的 android 2.1 列表视图中显示联系人号码

Question

我是 android 新手，我想在我自己的列表视图中显示电话簿中的联系号码。我已经实现了显示名称，但是当我尝试显示数字时，它会返回 1 或 0 的布尔数字。

我的代码是

public class Test extends ListActivity {
    static final String[] CONTACTS_SUMMARY_PROJECTION = new String[] {
            Contacts._ID,  
            Contacts.DISPLAY_NAME, 
            Contacts.STARRED,  
            Contacts.TIMES_CONTACTED,  
            Contacts.CONTACT_PRESENCE,  
            Contacts.PHOTO_ID,  
            Contacts.LOOKUP_KEY,  
            Contacts.HAS_PHONE_NUMBER                  
    };

    static final int SUMMARY_ID_COLUMN_INDEX = 0;
    static final int SUMMARY_NAME_COLUMN_INDEX = 1;
    static final int SUMMARY_STARRED_COLUMN_INDEX = 2;
    static final int SUMMARY_TIMES_CONTACTED_COLUMN_INDEX = 3;
    static final int SUMMARY_PRESENCE_STATUS_COLUMN_INDEX = 4;
    static final int SUMMARY_PHOTO_ID_COLUMN_INDEX = 5;
    static final int SUMMARY_LOOKUP_KEY = 6;
    static final int SUMMARY_HAS_PHONE_COLUMN_INDEX = 7;


    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        String select = "((" + Contacts.DISPLAY_NAME + " NOTNULL) AND ("
                + Contacts.HAS_PHONE_NUMBER + "=1) AND ("
                + Contacts.DISPLAY_NAME + " != '' ))";
        Cursor c =
                getContentResolver().query(Contacts.CONTENT_URI, CONTACTS_SUMMARY_PROJECTION, select,
                null, Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC");
        startManagingCursor(c);



        ContactListItemAdapter adapter = new ContactListItemAdapter(this, R.layout.main, c);
        setListAdapter(adapter);

    }

    private final class ContactListItemAdapter extends ResourceCursorAdapter {
        public ContactListItemAdapter(Context context, int layout, Cursor c) {
            super(context, layout, c);
        }


        @Override
        public void bindView(View view, Context context, Cursor cursor) {
            final ContactListItemCache cache = (ContactListItemCache) view.getTag();

            cursor.copyStringToBuffer(SUMMARY_NAME_COLUMN_INDEX, cache.nameBuffer);
            int size = cache.nameBuffer.sizeCopied;

            cursor.copyStringToBuffer(SUMMARY_HAS_PHONE_COLUMN_INDEX, cache.numberView);
            int number = cache.numberView.sizeCopied;


            cache.nameView.setText(cache.nameBuffer.data, 0, size);
            cache.numView.setText(cache.numberView.data, 0, number);
            final long contactId = cursor.getLong(SUMMARY_ID_COLUMN_INDEX);
            final String lookupKey = cursor.getString(SUMMARY_LOOKUP_KEY);
            cache.photoView.assignContactUri(Contacts.getLookupUri(contactId, lookupKey));

        }

        @Override
        public View newView(Context context, Cursor cursor, ViewGroup parent) {
            View view = super.newView(context, cursor, parent);
            ContactListItemCache cache = new ContactListItemCache();
            cache.nameView = (TextView) view.findViewById(R.id.name);
            cache.numView = (TextView) view.findViewById(R.id.number);
            cache.photoView = (QuickContactBadge) view.findViewById(R.id.badge);
            view.setTag(cache);

            return view;
        }
    }

    final static class ContactListItemCache {
        public TextView nameView;
        public TextView numView;
        public CharArrayBuffer numberView = new CharArrayBuffer(128);
        public QuickContactBadge photoView;
        public CharArrayBuffer nameBuffer = new CharArrayBuffer(128);
    }

提前致谢。

查看我更新的代码 ->

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);


    ContentResolver cr = new ContentResolver(this.getApplicationContext()) {
    };

    Cursor phones = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
            ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", null, null);

    phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));

    ContactListItemAdapter adapter = new ContactListItemAdapter(this, R.layout.main, phones);
    setListAdapter(adapter);

}

但它显示错误。帮我解决这个问题！

谢谢....

Answer 1

Contacts.HAS_PHONE_NUMBER 将返回联系人是否有电话号码。获取实际电话号码使用

ContactsContract.CommonDataKinds.Phone.NUMBER

使用以下代码获取有关所有联系人的信息。一世。 e 使用这个 URI

 Cursor phones = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
                                ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", "your contact id", null);

    phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));

这样您就可以在 OnCreate() 中查询联系人数据库时使用此代码

更新答案

在您的 OnCreate() 中，您正在使用电话号码和显示名称查询数据库。但现在您需要修改查询，以便您也能获得 contact id。

为此，您只需在联系人选择查询中添加 ID 字段。

 String select = "((" + Contacts.DISPLAY_NAME + " NOTNULL) AND ("
                + Contacts.HAS_PHONE_NUMBER + "=1) AND ("
                + Contacts.DISPLAY_NAME + " != '' ) AND (" + Contacts._ID + " NOTNULL ))";
        Cursor c =
                getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, CONTACTS_SUMMARY_PROJECTION, select,
                null, Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC");

获取此游标后，您需要从此游标中获取联系人 ID，并将该 ID 传递给下面的查询

Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
                                ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", "Put the contact id here", null);

phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));

Answer 2

这对我来说不合适：

ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ number, 

number 与 CONTACT_ID 有何关系？
