尝试检索联系人时出现错误

问题描述

| 在我的应用程序中，我试图检索电话簿的联系人。尽管我将联系人存储在模拟器中，但查询似乎未返回任何结果。我用下面的代码：

Cursor people = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,null,null);
    people.moveToFirst();
    while(people.moveToNext()) {
       int nameFieldColumnIndex = people.getColumnIndex(PhoneLookup.DISPLAY_NAME);
       String contact = people.getString(nameFieldColumnIndex);
       int numberFieldColumnIndex = people.getColumnIndex(PhoneLookup.NUMBER);
       String number = people.getString(numberFieldColumnIndex);
       Toast.makeText(this,\"\"+contact+\"\"+number,Toast.LENGTH_LONG);
    }

    people.close();

错误的日志是

解决方法

        使用以下代码从电话获取联系人

public static void getContactNumbers(Context context) {
        String contactNumber = null;
        int contactNumberType = Phone.TYPE_MOBILE;
        String nameOfContact = null;
        if (ApplicationConstants.phoneContacts.size() <= 0) {
            ContentResolver cr = context.getContentResolver();
            Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,null,null);
            if (cur.getCount() > 0) {
                while (cur.moveToNext()) {
                    String id = cur.getString(cur
                            .getColumnIndex(BaseColumns._ID));
                    nameOfContact = cur
                            .getString(cur
                                    .getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));

                    if (Integer
                            .parseInt(cur.getString(cur
                                    .getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
                        Cursor phones = cr
                                .query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,ContactsContract.CommonDataKinds.Phone.CONTACT_ID
                                                + \" = ?\",new String[] { id },null);

                        while (phones.moveToNext()) {
                            contactNumber = phones.getString(phones
                                    .getColumnIndex(Phone.NUMBER));
                            contactNumberType = phones.getInt(phones
                                    .getColumnIndex(Phone.TYPE));
                            Log.i(TAG,\"...Contact Name ....\" + nameOfContact
                                    + \"...contact Number...\" + contactNumber);

                        }
                        phones.close();
                    }

                }
            }// end of contact name cursor
            cur.close();

        }
    }
