So erhalten Sie die Telefonnummer von Person Name, die in meiner Kontaktliste sind in Android

Question

Ich möchte Telefon keine Person von seinem Namen, die in meiner Kontaktliste sind. Ich habe den folgenden Code verwendet, aber es funktioniert nicht gut. Sag mir, wo ich falsch liege.

  try {     
     cursor_company =getContentResolver().query(ContactsContract.Data.CONTENT_URI, 
null,ContactsContract.Data.DISPLAY_NAME+ " = " + "sidharth", null, null);   
       }   
     catch(Exception e)    
     {  
     System.out.println("this is exception "+e);    
     }   
     String phone_number;   
     while (cursor_company.moveToNext()) {   
     Phone_number =cursor_company.getString(   
     cursor_company.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));    
    System.out.println(" this is user no. is"+phone_number);   
       }    
     cursor_company.close();    
     }    

Die Ausnahme kam, als ich diesen Code laufen unter

android.database.sqlite.SQLiteException: no such column: bhawana: , while compiling: SELECT data_version, phonetic_name, phonetic_name_style, contact_id, lookup, data12, data11, data10, mimetype, data15, data14, data13, display_name_source, data_sync1, data_sync3, data_sync2, agg_presence.chat_capability AS contact_chat_capability, data_sync4, account_type, custom_ringtone, sp, status_updates.status AS status, data1, data4, data5, data2, data3, sns_id, data8, data9, group_sourceid, data6, account_name, data7, display_name, in_visible_group, display_name_alt, contacts_status_updates.status_res_package AS contact_status_res_package, is_primary, contacts_status_updates.status_ts AS contact_status_ts, raw_contact_id, times_contacted, contacts_status_updates.status AS contact_status, status_updates.status_res_package AS status_res_package, status_updates.status_icon AS status_icon, contacts_status_updates.status_i

Hier ist es:

static final String[] CONTACTS_SUMMARY_PROJECTION = new String[] { 
    ContactsContract.Contacts._ID, 
    ContactsContract.Contacts.DISPLAY_NAME, 
    ContactsContract.Contacts.STARRED, 
    ContactsContract.Contacts.TIMES_CONTACTED, 
    ContactsContract.Contacts.CONTACT_PRESENCE, 
    ContactsContract.Contacts.PHOTO_ID, 
    ContactsContract.Contacts.LOOKUP_KEY, 
    ContactsContract.Contacts.HAS_PHONE_NUMBER, 
}; 

String name_to_search = "sidharth"; 

String select = "(" + ContactsContract.Contacts.DISPLAY_NAME + " == \"" +name_to_search+ "\")"; 
Cursor c = context.getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, CONTACTS_SUMMARY_PROJECTION, select, null, ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC"); 
context.startManagingCursor(c); 

if (c.moveToNext()) 
{ 
    String id = c.getString(0); 
    ArrayList<String> phones = new ArrayList<String>(); 

    Cursor pCur = context.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?", new String[]{id}, null); 
    while (pCur.moveToNext()) 
    { 
     phones.add(pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER))); 
     Log.i("", name_to_search+ " has the following phone number "+ pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER))); 
    } 
    pCur.close(); 
}

Verwenden Sie die moveToFirst() Funktion des Cursors auf dem Spiel zu konzentrieren, und rufen Sie dann getString
