android – 如何使用一个查询搜索带地址的联系人(FORMATTED_ADDRESS)？

为了记录,这是我的工作示例.它解决了这个问题,但我仍然认为它会产生很大的负荷.在每个用户条目(afterTextchangE)上,我调用getContactsDetailsQuery,它首先获取所有用户的ID,其ID包含其名称(光标)中的查询,然后我为每个用户启动另一个查询(detailcursor)以获取地址.为了防止过载,我增加了一个限制..

public static List<SearchModel> getContactDetailsForQuery(Context context,String query,int limit) {

    final int CONTACT_ID_INDEX = 0;
    final int CONTACt_name_INDEX = 1;
    final int CONTACT_THUMBNAIL_INDEX = 2;

    //my custom model to hold my results
    List<SearchModel> results = new ArrayList<SearchModel>();

    final String[] SELEctUser = new String[]{
        Contacts._ID,Contacts.DISPLAY_NAME,Contacts.PHOTO_THUMBNAIL_URI};
    String selection = Contacts.DISPLAY_NAME + " LIKE ?";
    String[] SELEctionArgs = new String[]{"%" + query + "%"};
    String sortOrder = Contacts.DISPLAY_NAME + " ASC";

    cursor cursor = context.getContentResolver().query(Contacts.CONTENT_URI,SELEctUser,SELEctionArgs,sortOrder,null);

    int contactCounter = 0;
    if (cursor != null && cursor.moveToFirst()) {

        do {
            String contactID = cursor.getString(CONTACT_ID_INDEX);
            String displayName = cursor.getString(CONTACt_name_INDEX);
            String thumbnail = cursor.getString(CONTACT_THUMBNAIL_INDEX);

            //get user details with user id (this is the query i wanted to change in my question!!)
            cursor detailcursor = context.getContentResolver().query(ContactsContract.Data.CONTENT_URI,new String[]{
                    CommonDataKinds.StructuredPostal.FORMATTED_ADDRESS},ContactsContract.Data.CONTACT_ID + "=? AND " +
                    CommonDataKinds.StructuredPostal.MIMETYPE + "=?",new String[]{String.valueOf(contactID),CommonDataKinds.StructuredPostal.CONTENT_ITEM_TYPE},null);

            if (detailcursor != null && detailcursor.moveToFirst()) {
                //special case: user has several address,query all of them
                do {
                    String formattedAddress = detailcursor.getString(detailcursor.getcolumnIndex(CommonDataKinds.StructuredPostal.FORMATTED_ADDRESS));
                    //user has serveral adress -> init model for each adress
                    SearchModel contact = new SearchModel();
                    results.add(contact);
                    contactCounter++;

                } while (detailcursor.moveToNext() && contactCounter < limit);

            } else {

                //user has no adress -> init model
                SearchModel contact = new SearchModel();
                results.add(contact);
                contactCounter++;
            }

            detailcursor.close();

        } while (cursor.moveToNext() && contactCounter < limit);
    }
    cursor.close();

    return results;
}
