    Button hesaplaKod;

I want to take these three value then calculate with formula then show the result in second activity as a textview.
How can i calculate (sum or add this three value) then show in the second activity?

Answer 1

Use in first Activity

hesaplaKod.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {

                int value1= Integer.parseInt(EditText01.getText().toString());
                int value2= Integer.parseInt(EditText01.getText().toString());
                int value3= Integer.parseInt(EditText01.getText().toString());

                int add = value1+value2+value3;

                Intent intent = new Intent(FirstActivity.this,SecondActivity.class);
                intent.putExtra("AddValue", add);
                startActivity(intent);
            }
        });

And in onCreate of Second Activity get the value from this

int addvalue = getIntent().getExtras().getInt("AddValue");
