安卓得到ArrayList中的所有联系人的电话号码

问题描述

我想保存的所有联系人的电话号码在一个ArrayList但我不能找到一种方法如何。有没有办法让他们，而不是挑选他们一个个ContactsContract？

解决方案

  ContentResolver的CR = mContext.getContentResolver（）; //活动/应用android.content.Context
    光标光标= cr.query（ContactsContract.Contacts.CONTENT_URI，NULL，NULL，NULL，NULL）;
    如果（cursor.moveToFirst（））
    {
        ArrayList的＆LT;字符串＆GT; alContacts =新的ArrayList＆LT;字符串＆GT;（）;
        做
        {
            字符串ID = cursor.getString（cursor.getColumnIndex（ContactsContract.Contacts._ID））;

            if(Integer.parseInt(cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) ＆GT; 0）
            {
                光标pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID +=？，新的String [] {ID}，NULL）;
                而（pCur.moveToNext（））
                {
                    串contactNumber = pCur.getString（pCur.getColumnIndex（ContactsContract.CommonDataKinds.Phone.NUMBER））;
                    alContacts.add（contactNumber）;
                    打破;
                }
                pCur.close（）;
            }

        }而（cursor.moveToNext（））;
    }
 

I am trying to save all contacts telephone numbers in an ArrayList but I cant find a way how. Is there a way to get them instead of picking them one by one with ContactsContract?

解决方案

ContentResolver cr = mContext.getContentResolver(); //Activity/Application android.content.Context
    Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
    if(cursor.moveToFirst())
    {
        ArrayList<String> alContacts = new ArrayList<String>();
        do
        {
            String id = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));

            if(Integer.parseInt(cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0)
            {
                Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?",new String[]{ id }, null);
                while (pCur.moveToNext())
                {
                    String contactNumber = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                    alContacts.add(contactNumber);
                    break;
                }
                pCur.close();
            }

        } while (cursor.moveToNext()) ;
    }
