Android Buttons wont activate

Android Buttons wont activate

I know this has been asked a million times but none have led me to solving
my problem. The onclicklistener will not activate the code for any of the
buttons. Here are the different sections that apply to the five buttons.
Button btnGuysMax;
Button btnGuysMedium;
Button btnEven;
Button btnGirlsMedium;
Button btnGirlsMax;
....
private void init()
{
datasource = new BarsDataSource(this);
datasource.open();
Intent intent = getIntent();
long id = intent.getLongExtra("bar_id",0);
bar = datasource.getBarById(id);
title = (TextView)findViewById(R.id.title);
btnGuysMax = (Button)findViewById(R.id.btnGuysMax);
btnGuysMedium = (Button)findViewById(R.id.btnGuysMedium);
btnEven = (Button)findViewById(R.id.btnEven);
btnGirlsMedium = (Button)findViewById(R.id.btnGirlsMedium);
btnGirlsMax = (Button)findViewById(R.id.btnGirlsMax);
......
btnGuysMax.setOnClickListener(this);
btnGuysMedium.setOnClickListener(this);
btnEven.setOnClickListener(this);
btnGirlsMedium.setOnClickListener(this);
btnGirlsMax.setOnClickListener(this);
.....
@Override
public void onClick(View view)
{
//resetButtons();
switch (view.getId()) {
case R.id.btnGuysMax:
//bar.setSexRatio(-2);
//btnGuysMax.setBackgroundColor(guysMaxColor);
Toast.makeText(this,"Max clicked!",Toast.LENGTH_LONG);
break;
case R.id.btnGuysMedium:
bar.setSexRatio(-1);
Toast.makeText(this,"Medium clicked!",Toast.LENGTH_LONG);
//btnGuysMedium.setBackgroundColor(guysMediumColor);
break;
case R.id.btnEven:
bar.setSexRatio(0);
//Toast.makeText(this,"Medium clicked!",Toast.LENGTH_LONG);
break;
case R.id.btnGirlsMedium:
bar.setSexRatio(1);
//btnGirlsMedium.setBackgroundColor(girlsMediumColor);
break;
case R.id.btnGirlsMax:
bar.setSexRatio(2);
break;
