public class CustomDialog extends Dialog implements OnClickListener {
  Button okButton, cancelButton;
  Activity mActivity;

  public CustomDialog(Activity activity) {      
    super(activity);
    mActivity = activity;
    setContentView(R.layout.custom_dialog);
    okButton = (Button) findViewById(R.id.button_ok);
    okButton.setOnClickListener(this);
    cancelButton = (Button) findViewById(R.id.button_cancel);
    cancelButton.setOnClickListener(this);
  }

  @Override
  public void onClick(View v) {       
    if (v == cancelButton)
        dismiss();
    else {
        Intent i = new Intent(mActivity, ItemSelection.class);
        mActivity.startActivity(i);
    }
  }
}
