如何正确关闭对话框片段

Question

我尝试了两种解决方案来关闭片段，但这些都不适合我。 第一个解决方案：-

binding.closeBtn.setOnClickListener {
            dismiss()
        }

当我关闭此解决方案时，我的对话框背面完全空白。

第二种解决方案：-

close_btn.setOnClickListener {
            requireActivity().onBackPressed()
        }

当我关闭对话框时，我的整个应用程序都会关闭。

你能帮我解决我的问题吗

我认为这是关闭对话框的更好方法。

Fragment frag = getSupportFragmentManager().findFragmentByTag("fragment_dialog");
if (frag != null) {
    DialogFragment df = (DialogFragment) frag;
    df.dismiss();
}
