Android CursorAdapter，搜索字符串为联系人姓名或号码

嗨，我正在开发一个应用程序来搜索联系人。搜索字符串可以是数字或联系人姓名。我可以根据联系人姓名搜索列表。如果用户输入联系人号码，则不确定如何搜索该联系人。这是我正在使用的代码

      Cursor contacts = getContacts2(null);
        startManagingCursor(contacts);


        TestForCursorAdapter adapter = new TestForCursorAdapter(this, contacts);
        mTxtPhoneNo.setAdapter(adapter);
        mTxtPhoneNo.setOnItemClickListener(new AdapterView.OnItemClickListener() {

            public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                    long arg3) {
                Cursor cursor = (Cursor) arg0.getItemAtPosition(arg2);
                String number = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Phone.NUMBER));
                mTxtPhoneNo.setText(number);
            }
        });



    public Cursor getContacts2(String where)
    {
        Uri uri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
        String[] projection = new String[] {
                ContactsContract.CommonDataKinds.Phone._ID,
                ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME,
                ContactsContract.CommonDataKinds.Phone.TYPE,
                ContactsContract.CommonDataKinds.Phone.NUMBER};

        Cursor people = this.getContentResolver().query(uri, projection, null, null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " COLLATE LOCALIZED ASC");

        return people;
    }

请帮忙。谢谢

您只需要使用

Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_URI, searchString);

Android在查找URL方面做得很好，像这样

替代了您使用的其他URI我应该在runQueryOnBackgroundThread中使用这行代码吗？这解决了问题吗？你能接受这个答案来结束这个问题并把它从未回答的列表中去掉吗，谢谢
