Java 仅从号码中获取联系人姓名

假设我有一个编辑文本和一个按钮。在编辑文本中,您将键入一个号码,然后当您点击按钮时,它将显示联系人信息或返回该联系人的姓名

我尝试过各种各样的方法,但运气不佳。我成功地做到了最远的一个是以下。。。但我没能把名字还给你

Cursor phoneCursor = null;
    contactList = new HashMap<String,String>();

  try{
       Uri uContactsUri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;

      String strProjection = ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME;

      phoneCursor = getContentResolver().query(uContactsUri, null, null, null, strProjection);
      phoneCursor.moveToFirst();

      String name = "";
      String phoneNumber = "";

       int nameColumn = phoneCursor.getColumnIndex(Phone.DISPLAY_NAME);
       int phoneColumn = phoneCursor.getColumnIndex(Phone.NUMBER);



           phoneCursor.moveToNext();

        }
    }
    catch(Exception e){
        Log.e("[SmsMain] getContactData", e.toString());
    }
    finally{
       if(phoneCursor != null){
          phoneCursor.close();
          phoneCursor = null;
       }
    }
}
cursorphonecursor=null;
contactList=newHashMap();
试一试{
Uri uContactsUri=ContactsContract.commondatatypes.Phone.CONTENT\u Uri;
String strproject=contacts contract.commondatatypes.Phone.DISPLAY\u NAME;
phoneCursor=getContentResolver().query(uContactsUri,null,null,null,strProject);
phoneCursor.moveToFirst();
字符串名称=”;
字符串phoneNumber=“”;
int nameColumn=phoneCursor.getColumnIndex(Phone.DISPLAY\u NAME);
int phoneColumn=phoneCursor.getColumnIndex(Phone.NUMBER);
phoneCursor.moveToNext();
}
}
捕获(例外e){
Log.e(“[SmsMain]getContactData”,e.toString());
}
最后{
如果(phoneCursor!=null){
phoneCursor.close();
phoneCursor=null;
}
}
}

为此,您需要使用优化的PhoneLookup提供程序,如前所述

Uri=Uri.withAppendedPath(PhoneLookup.CONTENT\u FILTER\u Uri,Uri.encode(phoneNumber)); Cursor Cursor=resolver.query(uri,新字符串[]{PhoneLookup.DISPLAY_NAME},null,null,null)

使用以下方法获取联系人姓名,如果号码不存在,则返回相同的号码,而不是姓名

private String getContactNameFromNumber(String number) {
        // define the columns I want the query to return
        String[] projection = new String[] {
                Contacts.Phones.DISPLAY_NAME,
                Contacts.Phones.NUMBER };

        // encode the phone number and build the filter URI
        Uri contactUri = Uri.withAppendedPath(Contacts.Phones.CONTENT_FILTER_URL, Uri.encode(number));

        // query time
        Cursor c = getContentResolver().query(contactUri, projection, null,
                null, null);

        // if the query returns 1 or more results
        // return the first result
        if (c.moveToFirst()) {
            String name = c.getString(c
                    .getColumnIndex(Contacts.Phones.DISPLAY_NAME));
            return name;
        }

        // return the original number if no match was found
        return number;
    }
