دریافت دو عدد از ورودی EditText و نمایش حاصل ضرب در اندروید

کد:

Button Btn1 = (Button)findViewById(R.id.BtnViewMess);

        final TextView TxtV1 = (TextView)findViewById(R.id.TxtView1) ;



        Btn1.setOnClickListener(new OnClickListener() {

            public void onClick(View v) {

                try {

                    EditText Ed1 = (EditText) findViewById(R.id.editText1);

                    EditText Ed2 = (EditText) findViewById(R.id.editText2);

                    int i = Integer.parseInt(String.valueOf(Ed1.getText()));

                    int j = Integer.parseInt(String.valueOf(Ed2.getText()));



                    final int intTotal = i * j;



                    TxtV1.setText(String.valueOf(intTotal));

                }catch (Exception Cp){TxtV1.setText(Cp.getMessage());}

            }

        });
