Apps EditText widget

DevHenrik · Dec 21, 2014

Im quiet new to program for android.

I have got stuck with a, probably, very simple issue.

In my code I have two "EditText" to get numbers from the user and to be calculated together. But I dont get how to convert the input from text to calculateable numbers.

How do I solve this?

Thanks for help!

You can use the Integer:: parseInt function to turn a string to an integer or Float:: parseFloat if you need floating point values.

I got this thing working... here is the code!

public class MainActivity extends Activity

{
private TextView showNo;
private EditText firstNo, secondNo;

@override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

showNo = (TextView)findViewById(R.id.printout);
firstNo = (EditText)findViewById(R.id.firstInput);
secondNo = (EditText)findViewById(R.id.secondInput);

}

public void calculateBtn(View button) {
int no1 = Integer.parseInt(firstNo.getText().toString());
int no2 = Integer.parseInt(secondNo.getText().toString());
int calc = no1+no2;
showNo.setText( String.valueOf(calc));

}

}
