越来越联系人电话号码

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()); 

} 

你好我遇到的问题检索联系人的电话号码，每次我让这行代码

String Num = people.getString(NumIndex);

应用程序崩溃。我不明白为什么

这是编辑根据数字得到一个名字是真的吗？

   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();

大概becouse联系人有多个电话NRS喜欢的工作...... 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();
