Question

Cursor people = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
while (people.moveToNext()){
    int NameIndex = people.getColumnIndex(PhoneLookup.DISPLAY_NAME);
    int NumIndex = people.getColumnIndex(PhoneLookup.NUMBER);

    String Name = people.getString(NameIndex);
    //String Num = people.getString(NumIndex);

    myArr.add(Name.toString());
    myNum.add(Num.toString());

}

您好我每次启用此行代码时都会在检索联系人电话号码时遇到问题

String Num = people.getString(NumIndex);

应用程序崩溃..我不明白为什么

这是基于数字获取名称的编辑是真的吗？

              if(state==TelephonyManager.CALL_STATE_RINGING)
              {
                //  Find contact based on name.
                  ContentResolver cr = getContentResolver();
                  Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI, null,
                      "NUMBER = '" + number + "'", null, null);
                  if (cursor.moveToFirst()) {
                      String contactId =
                          cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
                      //  Get all phone numbers.
                      Cursor phones = cr.query(Phone.CONTENT_URI, null,
                          Phone.CONTACT_ID + " = " + contactId, null, null);
                      while (phones.moveToNext()) {
                          String numb = phones.getString(phones.getColumnIndex(Phone.DISPLAY_NAME));
                      }
                      phones.close();
                   }
                  cursor.close();

可能是因为联系人有多个电话号码，比如工作...... 试试这个：

//  Find contact based on name.
        //
        ContentResolver cr = getContentResolver();
        Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI, null,
            "DISPLAY_NAME = '" + NAME + "'", null, null);
        if (cursor.moveToFirst()) {
            String contactId =
                cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
            //
            //  Get all phone numbers.
            //
            Cursor phones = cr.query(Phone.CONTENT_URI, null,
                Phone.CONTACT_ID + " = " + contactId, null, null);
            while (phones.moveToNext()) {
                String number = phones.getString(phones.getColumnIndex(Phone.NUMBER));
                int type = phones.getInt(phones.getColumnIndex(Phone.TYPE));
                switch (type) {
                    case Phone.TYPE_HOME:
                        // do something with the Home number here...
                        break;
                    case Phone.TYPE_MOBILE:
                        // do something with the Mobile number here...
                        break;
                    case Phone.TYPE_WORK:
                        // do something with the Work number here...
                        break;
                    }
            }
            phones.close();
         }
    cursor.close();
