android - 从android中的指定组获取联系人

Question

我正在尝试从特定的已知 ID 组中获取联系人。我能够获取该组中的组 ID 和联系人姓名。但我无法获取联系电话。尝试了一些来自谷歌搜索的解决方案，但每次我得到的电话号码与组 ID 相同时，如果我使用 Phone.number 和 Phone.DISPLAY_NAME 查询组中的电话号码和联系人姓名。如果我使用以下方法，则会出现错误 请帮我弄清楚我的代码有什么问题。

代码:

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.group_contacts);
        addGroups = (Button) findViewById(R.id.selectGroup);

        groupAdapter = new SimpleCursorAdapter(getApplicationContext(),
                android.R.layout.select_dialog_singlechoice, GroupCursor(),
                new String[] { ContactsContract.Groups.TITLE },
                new int[] { android.R.id.text1 });
        setListAdapter(groupAdapter);
        getListView().setChoiceMode(ListView.CHOICE_MODE_SINGLE);

        addGroups.setOnClickListener(new OnClickListener() {

            public void onClick(View v) {

                Intent intent = new Intent(myGroups.this, Main.class);
                Bundle carry = new Bundle();
                carry.putStringArrayList("numbers", cNumbers);
                carry.putStringArrayList("name", cNames);
                intent.putExtras(carry);
                setResult(RESULT_OK, intent);
                finish();
            }
        });

    }

    private Cursor GroupCursor() {

        String[] projection = { ContactsContract.Groups.TITLE,
                ContactsContract.Groups._ID };
        Cursor gCursor = getContentResolver().query(
                ContactsContract.Groups.CONTENT_URI, projection, null,                   null,
                ContactsContract.Groups.TITLE);

        // int idcolumn = gCursor.getColumnIndex(ContactsContract.Groups._ID);
        // String id = gCursor.getString(idcolumn);

        // Log.d(E, "group id : " + id );
        return gCursor;

    }

    @Override
    protected void onListItemClick(ListView l, View v, int position, long id) {

        super.onListItemClick(l, v, position, id);
        Log.d(E, "id : " + id);
        String groupId = Long.toString(id);

        String[] cProjection = { Phone.NUMBER, Phone.DISPLAY_NAME ,Contacts.DISPLAY_NAME, Contacts._ID};

        Cursor groupCursor = getContentResolver().query(Data.CONTENT_URI,
                cProjection,
                CommonDataKinds.GroupMembership.GROUP_ROW_ID + "= ?",
                new String[]{groupId}, null);
        if (groupCursor != null) {
            groupCursor.moveToFirst();
            do {

                int nameCoumnIndex = groupCursor
                        .getColumnIndex(Phone.DISPLAY_NAME);

                String name = groupCursor.getString(nameCoumnIndex);

                String cId = groupCursor.getString(groupCursor.getColumnIndex(Contacts._ID));

                Cursor numberCursor = getContentResolver().query(Phone.CONTENT_URI, new String[]{Phone.NUMBER}, Phone._ID +"="+cId, null, null);
                numberCursor.moveToFirst();
                int numberColumnIndex = numberCursor
                        .getColumnIndex(Phone.NUMBER);
                Log.d(E, "numberindex : " + numberColumnIndex);

                String number = numberCursor.getString(numberColumnIndex);

                cNumbers.add(number);

                Log.d(E, "contact " + name + ":" + number);

                cNames.add(name);
            } while (groupCursor.moveToNext());
        }
    }
}

尝试在您的 onListItemClick 方法中使用以下代码:

long groupId = id;
    String[] cProjection = { Contacts.DISPLAY_NAME, GroupMembership.CONTACT_ID };

    Cursor groupCursor = getContentResolver().query(
            Data.CONTENT_URI,
            cProjection,
            CommonDataKinds.GroupMembership.GROUP_ROW_ID + "= ?" + " AND "
                    + ContactsContract.CommonDataKinds.GroupMembership.MIMETYPE + "='"
                    + ContactsContract.CommonDataKinds.GroupMembership.CONTENT_ITEM_TYPE + "'",
            new String[] { String.valueOf(groupId) }, null);
    if (groupCursor != null && groupCursor.moveToFirst())
    {
        do
        {

            int nameCoumnIndex = groupCursor.getColumnIndex(Phone.DISPLAY_NAME);

            String name = groupCursor.getString(nameCoumnIndex);

            long contactId = groupCursor.getLong(groupCursor.getColumnIndex(GroupMembership.CONTACT_ID));

            Cursor numberCursor = getContentResolver().query(Phone.CONTENT_URI,
                    new String[] { Phone.NUMBER }, Phone.CONTACT_ID + "=" + contactId, null, null);

            if (numberCursor.moveToFirst())
            {
                int numberColumnIndex = numberCursor.getColumnIndex(Phone.NUMBER);
                do
                {
                    String phoneNumber = numberCursor.getString(numberColumnIndex);
                    Log.d("your tag", "contact " + name + ":" + phoneNumber);
                } while (numberCursor.moveToNext());
                numberCursor.close();
            }
        } while (groupCursor.moveToNext());
        groupCursor.close();
    }

查询属于指定组的联系人时需要指定mimetype。而且由于一个联系人可以有多个电话号码，您可能需要查询所有电话号码。

编辑: 要获取至少有一个电话号码联系人的所有组，您可以使用以下查询:

ContentResolver cr = getContentResolver();
Uri groupsUri = ContactsContract.Groups.CONTENT_SUMMARY_URI;
String where = "((" + ContactsContract.Groups.GROUP_VISIBLE + " = 1) AND (" 
                + ContactsContract.Groups.SUMMARY_WITH_PHONES + "!= 0))";
Cursor cursor = cr.query(groupsUri, null, where, null, null);

至于从指定组获取联系人电话号码 - 我不知道简单的解决方案。
