How to display contact name or display_name of contact in list off messeges - android-studio

Question

How could I display the names of the following numbers in my Listview if the numbers are given in the loop.
void FetchAllMessages(){
msgList = new ArrayList<>();
Cursor cursor = getContentResolver().query(Uri.parse("content://sms/inbox"), null, null, null, null);
if (cursor.moveToFirst()) {
do {
String from = cursor.getString(cursor.getColumnIndex("address"));
Uri uri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(from));
Cursor phones = getContentResolver().query(uri, new String[]{ContactsContract.PhoneLookup.DISPLAY_NAME}, null, null, null);
if(phones.moveToFirst()){
contactname = cursor.getString(cursor.getColumnIndex(ContactsContract.PhoneLookup.DISPLAY_NAME));
msgList.add(contactname);
}else{
msgList.add(from);
}
} while (cursor.moveToNext());
}
}
There is no display in my android and it continue to crash.
Any help is much appreciated.

It seems you didn't write code for no contacts check. Try this code
ContentResolver cr = cntx.getApplicationContext().getContentResolver();
//Query to get contact name
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,null,null,null,null);
// If data data found in contacts
ArrayList<String> msgList = new ArrayList<String>();
if (cur.getCount() > 0) {
int k = 0;
String name = "";
while (cur.moveToNext()) {
String id = cur
.getString(cur
.getColumnIndex(ContactsContract.Contacts._ID));
name = cur
.getString(cur
.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
//Check contact have phone number
if (Integer
.parseInt(cur
.getString(cur
.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
//Create query to get phone number by contact id
Cursor pCur = cr
.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID
+ " = ?",
new String[]{id},
null);
int j = 0;
while (pCur
.moveToNext()) {
// Sometimes get multiple data
if (j == 0) {
// Get Phone number
phoneNumber = "" + pCur.getString(pCur
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
if (phoneNumber.startsWith("+91")) {
phoneNumber = phoneNumber.substring(3, phoneNumber.length());
}
phoneNumber = phoneNumber.replaceAll("\\s", "");
if (phoneNumber.length() == 10) {
// Add contacts names to arrayList
msgList.add(name.toString());
}
j++;
k++;
}
} // End while loop
pCur.close();
} // End if
} // End while loop
} // End Cursor value check
cur.close();
