    Add this line to your code:

    addPreferencesFromResource(R.xml.preferences);

    This code is working:

    import android.app.AlertDialog;
import android.app.AlertDialog.Builder;
import android.content.DialogInterface;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.preference.Preference;
import android.preference.Preference.OnPreferenceClickListener;
import android.preference.PreferenceActivity;
import android.preference.PreferenceManager;

public class Reset extends PreferenceActivity{

private Preference myPreference;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.preferences);
myPreference = findPreference("reset");
myPreference.setOnPreferenceClickListener(new OnPreferenceClickListener() {
    public boolean onPreferenceClick(Preference arg0) {
        Builder alertDialog = new AlertDialog.Builder(Reset.this);
        alertDialog.setMessage("Reset?");
        alertDialog.setCancelable(true);
        alertDialog.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int which) {
                SharedPreferences settings =   PreferenceManager.getDefaultSharedPreferences(getBaseContext());                          
                SharedPreferences.Editor editor = settings.edit();
                editor.clear();
                editor.commit();
            } }); 
        alertDialog.setNegativeButton("No", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int which) {
                dialog.cancel();
            } }); 
        alertDialog.show();
        return false;
    }
});

}

}

    And remember to add your activity: Reset to the Manifest:
