联系人的身份证号码
问题描述:
我可以从她的身份证中找到联系人的号码。以下代码片段在屏幕上打印一个数字。联系人的身份证号码
Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
CONTACT_PROJECTION,ContactsContract.CommonDataKinds.Phone._ID +" = 4627",
null, null);
phones.moveToNext();
String phoneNumber = phones.getString(
phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
Toast.makeText(getBaseContext(), phoneNumber, Toast.LENGTH_LONG).show();
但是,如果我试图找到她的号码她的ID,
Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
CONTACT_PROJECTION,ContactsContract.CommonDataKinds.Phone._ID +" = 4627",
null, null);
phones.moveToNext();
String phoneNumber = phones.getString(
phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
//Now I got a valid phone number
//using that number to find the id
Cursor ids = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
CONTACT_PROJECTION,ContactsContract.CommonDataKinds.Phone.NUMBER +" = "+ phoneNumber,
null, null);
ids.moveToNext();
String id = ids.getString(
ids.getColumnIndex(ContactsContract.CommonDataKinds.Phone._ID));
Toast.makeText(getBaseContext(), id, Toast.LENGTH_LONG).show();
我碰到下面的错误。
android.database.CursorIndexOutOfBoundsException: Index 0 requested, with a size of 0
我使用的投影如下:
private static final String[] CONTACT_PROJECTION = new String[] {
ContactsContract.CommonDataKinds.Phone.NUMBER,
ContactsContract.CommonDataKinds.Phone._ID
};
第二光标是空的,即使我知道有在接触这样的条目。我究竟做错了什么?
答
不知道为什么,但PhoneLookup为我工作。对于那些有同样问题的人,这里是我的代码。
Uri contactUri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode("aNumber"));
Cursor phones = getContentResolver().query(contactUri , PEOPLE_PROJECTION, null, null, null);
//here, the cursor keeps the wanted contact
...
private static final String[] PEOPLE_PROJECTION = new String[] {
ContactsContract.PhoneLookup._ID
};
我记得有一个内容过滤器uri与电话号码查询。 – 2012-02-22 06:04:04
所以你说:ContactsContract.CommonDataKinds.Phone.NUMBER!= ContactsContract.PhoneLookup.NUMBER(这是我不知道的) – 0x5f3759df 2012-02-22 06:06:18
