Question

I perform calculations using a double as follows:

int minutes;
double seconds;
double DecMinutes;


// Handle Dd in; DMS, and DMm out
Calculate myCalculate = new Calculate(inDecimal); {
double outMinutes = myCalculate.getMinute();
double outSeconds = myCalculate.getSecond();
double outDecMinute = myCalculate.getDecMinute();


minutes = (int) outMinutes;
seconds = outSeconds;
DecMinutes = outDecMinute;


} // end myCalculate

// Convert result back to String
c = Integer.toString(minutes);
((EditText)findViewById(R.id.txtDMSLatMin)).setText(c);
((EditText)findViewById(R.id.txtDMmLatMin)).setText(c);
c = Double.toString(seconds);
((EditText)findViewById(R.id.txtDMSLatSec)).setText(c);
c = Double.toString(DecMinutes);
((EditText)findViewById(R.id.txtDMmLatDecMin)).setText(c);

My main concern is with the double DecMinutes output. Because it’s a Decimal-Minutes calculation I need to use double. My layout already displays the decimal point as a fixed character so instead of displaying 0.0734 I want to display 0734 in the EditText box txtDMmLatDecMin.

Thanks!!

Answer 1

So basically, you want to drop the zero and the decimal point?

Maybe there is an easier way, but at the top of my head I am thinking you can use String.split(). With the downside that you have to create a new String array to hold the values.

So after you do this:

c = Double.toString(DecMinutes);
String[] strSplit = c.split("\\.");

Then you can do:

((EditText)findViewById(R.id.txtDMmLatDecMin)).setText(strSplit[1]);

Again, maybe there is an easier way. 🙂
