Hi,
I am new to Android development and I am currently working through a
tutorial but have already run into a brick wall. I am trying to handle
a simple button click following some sample code but can't get it to
work. I do not get any errors, but the click does not register on the
emulator. I have set breakpoints and confirmed that the handler never
gets executed. I have attached the complete code below. Any help would
be appreciated.
package com.test.HelloWorld;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.RadioButton;
import android.widget.TextView;
public class mainPage extends Activity {
TextView dollars;
TextView euros;
TextView debug;
RadioButton dtoe;
RadioButton etod;
Button convert;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
dollars = (TextView)this.findViewById(R.id.dollars);
euros = (TextView)this.findViewById(R.id.euros);
debug = (TextView)this.findViewById(R.id.Debug);
dtoe = (RadioButton)this.findViewById(R.id.dtoe);
etod = (RadioButton)this.findViewById(R.id.etod);
dtoe.setChecked(true);
debug.setText("Program Started..");
convert = (Button)this.findViewById(R.id.convert);
convert.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
if (dtoe.isChecked())
{
convertDollarsToEuros();
}
if (etod.isChecked())
{
convertEurosToDollars();
}
}
});
}
protected void convertDollarsToEuros()
{
double val = Double.parseDouble(dollars.getText().toString());
euros.setText(Double.toString(val*0.67));
debug.setText(euros.getText());
}
protected void convertEurosToDollars()
{
double val = Double.parseDouble(euros.getText().toString());
dollars.setText(Double.toString(val/0.67));
}
}
