amntpaid EditText value should be add in total EditText.But when I am running the below code, the addition is not happening. Check my code. 

String subtotal=String.valueOf(amntpaid);
String total =String.valueOf(totamnt);
total = total+subtotal;
String ncr=total+"";
totalamt.setText(ncr);

Do something like this: do the sum of amntpaid and totamnt and store it in some int variable say var like

var=Integer.parseInt(amntpaid.getText())+Integer.parseInt(totamnt.getText());
String value_to_be_set=String.valueOf(var);
totalamnt.setText(value_to_be_set);

where totalamnt is the TextView in which you want to set the value,and amntpaid and totamntare your EditText from where you will get the entered input value.

You need to use either

Integer.parseInt(stringValue);

or 

Integer.valueOf(stringValue);

for those edittexts.

Try below code : 

int i = Integer.parseInt(et1.getText().toString().trim());

int j = Integer.parseInt(et2.getText().toString().trim());

int total = i + j;

String sum = total + "";

This is just a sample and you have to modify it accordingly.

TextView resultTV;
EditText ed1, ed2;
Button add;

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.your_xml);

resultTV = (TextView) findViewById (R.id.your_tv_id)  // do the same for both edittexts and button


 add.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

  String s1 = ed1.getText().toString();
  String s2 = ed2.getText().toString();
  if (!s1.trim().equals("") && !s2.trim().equals("")
  {
     int first = Integer.parseInt(s1);
     int second = Integer.parseInt(s2);
     int sum = first + second;
      resutTV.setText(sum + "");
  }
   else
   resultTV.setText("Please enter the values");
 }

    });

You are adding one string to another you need to TypeCast String data to Integer then only it will add

String subtotal = String.valueOf(amntpaid);
String total = String.valueOf(totamnt);
int sum = Integer.parseInt(total) + Integer.parseInt(subtotal);
totalamt.setText(sum + "");

You're trying to add 2 strings, convert it to int first

String amount = amntpaid.getText().toString();
String total = totamnt.getText().toString();
int totalInt = Integer.parseInt(amount) + Integer.parseInt(total);
totalamt.setText("" + totalInt);
