android实现读取、搜索联系人的代码

代码很简单，就不多废话了

//读取联系人
public static uri contactsuri = contactscontract.contacts.content_uri;//联系人
    public static void getcontactsinfo(context context,string tag){
        string[] projections = new string[]{contactscontract.contacts._id,contactscontract.contacts.display_name};
        cursor cursor = context.getcontentresolver().query(contactsuri, projections, null, null, null);
        int albumindex = cursor.getcolumnindexorthrow(projections[0]);
        int titleindex = cursor.getcolumnindexorthrow(projections[1]);
        log.d(tag, cursor.getcount()+"");
        while(cursor.movetonext()){
            string album = cursor.getstring(albumindex);
            string title = cursor.getstring(titleindex);
            log.d(tag, album+":"+title);
        }
        cursor.close();
    }
    
    //根据联系人搜索联系人信息
    public static void searchcontacts(context context,string tag){
        string searchname = "wang";
        uri uri = uri.withappendedpath(contactscontract.contacts.content_filter_uri, searchname);
        
    //  uri uri2 = uri.withappendedpath(contactscontract.phonelookup.content_filter_uri, phonenumber); 根据电话号码查找联系人
        
        string[] projection = new string[]{contactscontract.contacts._id};
        cursor cursor = context.getcontentresolver().query(uri, projection, null, null, null);
        string id = null;
        if (cursor.movetofirst()) {
            id = cursor.getstring(cursor.getcolumnindexorthrow(contactscontract.contacts._id));
        }
        cursor.close();
        if (id!=null) {
            string where = contactscontract.data._id+"="+id;
            projection = new string[]{contactscontract.data.display_name,contactscontract.commondatakinds.phone.number};
            cursor searchccursor = context.getcontentresolver().query(contactscontract.data.content_uri, projection, where, null, null);
            log.d(tag, searchccursor.getcount()+"");
            int nameindex = searchccursor.getcolumnindex(projection[0]);
            int numberindex = searchccursor.getcolumnindex(projection[1]);
            while(searchccursor.movetonext()){
                string name = searchccursor.getstring(nameindex);
                string number = searchccursor.getstring(numberindex);
                log.d(tag, number+":"+name);
            }
            searchccursor.close();
        }
    }
