Question

我想从Android的联系人详细信息中获取电子邮件地址和电话号码。我可以拿起电话号码，但我希望在选择电话号码时也可以皮卡电子邮件地址到其相应的联系人id.so我可以将其添加到arraylist。 谢谢

public void getContactslist() 
    { 
     ContentResolver contactResolver = getContentResolver(); 
     Cursor cursor = contactResolver.query(Phone.CONTENT_URI , null,null,null, null); 
     // Cursor emails = contactResolver.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, null,null, null, null); 
     if(cursor.getCount() > 0) 
     { 
      cursor.moveToFirst(); 
      do { 
       String number = cursor.getString(cursor.getColumnIndex(Phone.NUMBER)); 
       String displayname = cursor.getString(cursor.getColumnIndex(Phone.DISPLAY_NAME)); 
       long contactid = cursor.getLong(cursor.getColumnIndex(Phone.CONTACT_ID)); 
       Cursor emails = getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, null, ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = " + contactid, null, null); 
       System.out.println("**emails*******"+number); 
       while (emails.moveToNext()) 
       { 
        String email = emails.getString(emails.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA)); 
        Log.e("Email", email); 
       }

我试过下面的代码段，它的工作原理。希望这可以帮助你。

public HashMap<String, String> getNameEmailDetails(){ 
    HashMap<String, String> names = new HashMap<String, String>(); 
    ContentResolver cr = getContext().getContentResolver(); 
    Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,null, null, null, null); 
    if (cur.getCount() > 0) { 
     while (cur.moveToNext()) { 
      String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID)); 
      Cursor cur1 = cr.query(
        ContactsContract.CommonDataKinds.Email.CONTENT_URI, null, 
        ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?", 
        new String[]{id}, null); 
      while (cur1.moveToNext()) { 
       //to get the contact names 
       String name=cur1.getString(cur1.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)); 
       Log.e("Name :", name); 
       String email = cur1.getString(cur1.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA)); 
       Log.e("Email", email); 
       if(email!=null){ 
        names.put(name, email); 
       } 
      } 
      cur1.close(); 
     } 
    } 
    return names; 
}
