I can solve it with the replace function;
String aap = "123,55".replace(",", ".");
But i though there maybe a sort off de-locale function which can read
strings, with with comma or point, and convert it
to a double.

[android-beginners] string to double
Hello,
Is there an function to change an string with a comma to a double.
example code;
stripline1.Z0 = "123.45" (with point)
DecimalFormat df = new DecimalFormat("#.##");
strip_Z0.setText(df.format(stripline1.Z0));
The value in the textEdit entry will be with a comma or point, depending on
the locale setting.
If I convert the string, with comma, directly to a double I get a "force
close".
How do I transform a string with comma to a string with point.
Faust

Here is some of the code;
NumberFormat df3 = new DecimalFormat("#.###");
if(radio_RL1.isChecked() == true)
{
mismatch.RL1= new Double(RL1.getText().toString());
mismatch.RL2= new Double(RL2.getText().toString());
mismatch.calcMismatch_RL();
VSWR1.setText(df3.format(mismatch.VSWR1));
VSWR2.setText(df3.format(mismatch.VSWR2));
}
if(radio_VSWR1.isChecked() == true)
{
mismatch.VSWR1= new Double(VSWR1.getText().toString());
mismatch.VSWR2= new Double(VSWR2.getText().toString());
mismatch.calcMismatch_VSWR();
RL1.setText(df3.format(mismatch.RL1));
RL2.setText(df3.format(mismatch.RL2));
}

[android-beginners] problem with edittext
Hello all, I have a made simple calculator let say from dollar to euro. There are two radiobuttons and two edittext entries one for dollar and one for euro . And there is one calculate button. I select one radio button (dollar) fill in a value for dollar and press calculate. The value of euro appears in the edittext entry. When i now select the radio button for euro and leave the first calculated value in the edittext entry the application will close. But when i first remove the calculated value and put in by hand and press calculate it runs fine. The emulator does not show this probem. To try it out download mwcalculator_lite and chose reflectometer calculator. Faust -- You received this message because you are subscribed to the Google Groups "Android Beginners" group. NEW!
