setOnPreferenceClickListener Help, Forclosing when activity launches

I know this cannot be as hard I think it is. I am sure I have everything that I can suppose to to implement my onClickListener. Am I missing something, why does this forceclose? I have provided the stack to take a look at. Any help would be great. This was suppose to be a simple activity to save user settings. If I comment out this code the activity displays the activity.

Preference customPref = (Preference) findPreference("customPref");

customPref.setOnPreferenceClickListener(new OnPreferenceClickListener() { //this line forcecloses every time i run the activity.
    @Override
    public boolean onPreferenceClick(Preference preference) {
        Toast.makeText(getBaseContext(),
                       "The custom preference has been clicked",
                       Toast.LENGTH_LONG)
             .show();
        SharedPreferences customSharedPreference = getSharedPreferences(
                "myCustomSharedPrefs", Activity.MODE_PRIVATE);
        SharedPreferences.Editor editor = customSharedPreference.edit();
        editor.putString("myCustomPref", "The preference has been clicked");
        editor.commit(开发者_JAVA技巧);
        return true;
    }
});

It looks like your customPref variable is null. Make sure you have preference with key customPref in your preference xml (if you use one) or maybe you've misspelled the key there.
