Android “取消我必须更新”按钮对话框

我有一个小问题，为什么我的dismissListener在关闭对话框时不想触发。我不知道为什么。我试图调试，但我不知道我设置错了什么：请帮助我

调用ChooseDialog，但此函数不会在关闭时触发：

    cd = new ChooseDialog(getApplicationContext());

cd.setOnDismissListener(new Dialog.OnDismissListener() {

    @Override
    public void onDismiss(DialogInterface dialog) {
        // TODO Auto-generated method stub

        if (click != -1) {

            Button b = (Button) findViewById(PositionButtons.click);
            b.setText(keypadButton.getText());
            PositionButtons.click = -1;
        }

    }
});

ChoseDialog：

所以问题是你的OnDismissListener没有被调用？是的，你是说该方法根本没有被调用，还是只是按钮上的文本没有更新？我从gridview获取数据的最佳方法是什么
