Hi guys,
I'm new here, as well, very tired from coding (alot of trial and error) for the past few hours.
I have an intro to java class under my belt and I'm having alot of trouble with Exceptions in my application. The issue is that I have multiple EditTexts for numerical entry and the data is then used in a formula. The formula is then supposed to output to another EditText. I'm just having a lot of difficulty with the formula part and outputting.
Here's the code, any help would be much appreciated, thanks.
If you need the rest, I don't have a problem posting it but I am quite certain the problem is here, my variables are declared private at the beginning.

Code:
private void Home(){
avg = (EditText) findViewById(R.id.avg);
avg.setFilters(new InputFilter[] {new DecimalDigitsInputFilter(3,2)});
cavg = (EditText) findViewById(R.id.cavg);
cavg.setFilters(new InputFilter[] {new DecimalDigitsInputFilter(3,2)});
std = (EditText) findViewById(R.id.stddev);
std.setFilters(new InputFilter[] {new DecimalDigitsInputFilter(3,2)});
isg = (EditText) findViewById(R.id.isg);
isg.setFilters(new InputFilter[] {new DecimalDigitsInputFilter(3,2)});
calculate = (Button)findViewById(R.id.calculate);
reset = (Button)findViewById(R.id.reset);
calculate.setOnClickListener(new Button.OnClickListener() { public void onClick (View v){
try {
calculate();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}});
reset.setOnClickListener(new Button.OnClickListener() { public void onClick (View v){ try {
reset();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
} }});
}
private void calculate() throws Exception{
double CRC = 0;
Log.d("calculate", "Before the variables");
a=Double.parseDouble(avg.getText().toString());
c=Double.parseDouble(cavg.getText().toString());
s=Double.parseDouble(std.getText().toString());
i=Double.parseDouble(isg.getText().toString());
Log.d("calculate", "After the variables");
CRC = 5 * (((a - c) / s) + 5 + ((i - 75) / 14));
Log.d("calculate", "After calculation");
RC.setText(Double.toString(CRC));
Log.d("calculate", "displaying");
}
