I think I found what u were talking about.
myCalcButton.setOnClickListener(new Button.OnClickListener()
{
public void onClick(View v)
{
double billNum = Double.parseDouble(myBillAmt.getText
().toString());
double preNum = Double.parseDouble
(myPrecentage.getText().toString());
myAns.setText(""+calcTip(billNum,preNum));
}
}
);
I dont relly understand what is going on here though. Could you please
explain this to me?
