我试图读取联系人的电话号码，但无法让它工作...

我的代码与 此处

---

ContentResolver cr = getContentResolver();
    Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null,null, null, null);

    if (cur.getCount() > 0) 
    {
        contacts = new String[cur.getCount()];
        numbers = new String[cur.getCount()];
        int index = 0;
        while (cur.moveToNext()) 
        {
            String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
            String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));

            contacts[index] = name;             
            MyListAdapter listAdapt = new MyListAdapter(MeetUp.this, R.layout.row, contacts);
            MeetUp.this.setListAdapter(listAdapt);


            if ( Integer.parseInt(cur.getString(cur.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());
                {
                    numbers[index] = pCur.getString( pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));               
                }
            }
            index++;
        }
    }

我的 logcat 输出：

失败的联系人肯定有一个号码，但调试后我认为 pCur 没有数字列..有什么想法为什么会发生这种情况吗？提前致谢——迈克

Answer 1

我认为在开始枚举之前您可能需要调用 cursor.moveToFirst() 。

Answer 2

尝试使用此代码来检索联系人：

        ContentResolver cr1 = getContentResolver();
    String[] projection = new String[] {People._ID,People.NAME,People.NUMBER};
    Uri contacts =  People.CONTENT_URI;
    // Make the query. 
    Cursor managedCursor = cr1.query(contacts, projection, null, null, People.NAME + " ASC");
        if (managedCursor.moveToFirst()) {
            String contactname; 
            String cphoneNumber; 
            int nameColumn = managedCursor.getColumnIndex(People.NAME); 
            int phoneColumn = managedCursor.getColumnIndex(People.NUMBER);
            do {
                // Get the field values
                contactname = managedCursor.getString(nameColumn);
                cphoneNumber = managedCursor.getString(phoneColumn);
                if((cphoneNumber!= "" && cphoneNumber!=null)|| (contactname!="" && contactname!=null)){
                    c_Name.add(contactname);
                    c_Number.add(cphoneNumber);
                }
            } while (managedCursor.moveToNext());
        }

这将检索姓名和号码...

我发现问题是什么了！ while 循环，特别是 moveToNext() 调用使其崩溃。如果您摆脱循环，则工作正常！

pCur.moveToFirst();
numbers[index] = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
