Android setOnDismissListener 没有在 onCreateDialog 中被调用 AlertDialog.Builder？

Question

我在 activity 上有一个按钮，通过调用此方法可以打开我的自定义对话框

public void openHcoDialog(View v) {
        HcoDialog hcoDiag = new HcoDialog();
        // Supply cityCode input as an argument.
        Bundle args = new Bundle();
        args.putString("cityCode", cityCode);
        hcoDiag.setArguments(args);
        hcoDiag.show(getSupportFragmentManager(), "hco dialog");
    }

在这个 HcoDialog 中 class 我已经扩展了 extends DialogFragment as

public class HcoDialog extends DialogFragment {

@NonNull
    @Override
    public Dialog onCreateDialog(@Nullable Bundle savedInstanceState) {

        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
        LayoutInflater inflater = getActivity().getLayoutInflater();
        View view = inflater.inflate(R.layout.hco_dialog, null);
        builder.setView(view);
        builder.setCancelable(true);

        builder.setOnCancelListener(new DialogInterface.OnCancelListener() {
            @Override
            public void onCancel(DialogInterface dialog) {
                Toast.makeText(getActivity(), "Toast 1", Toast.LENGTH_LONG).show();
                progressDialog.dismiss();
            }
        });

        builder.setOnDismissListener(new DialogInterface.OnDismissListener() {
            @Override
            public void onDismiss(DialogInterface dialog) {
                Toast.makeText(getActivity(), "Toast 2", Toast.LENGTH_LONG).show();
                progressDialog.dismiss();
            }
        });

}

因此，当我关闭对话框时，通过单击外部或按后退按钮，对话框关闭但 progressDialog 将运行保持为 onDismiss 或 onCancel 从未被调用过？

我现在正努力解决这个问题。已阅读许多 Whosebug 答案，但 none 似乎有效。

提前致谢。

根据 onCreateDialog() documentation:

Note: DialogFragment own the Dialog.setOnCancelListener and Dialog.setOnDismissListener callbacks. You must not set them yourself. To find out about these events, override onCancel(DialogInterface) and onDismiss(DialogInterface).

因此您必须将逻辑移至 DialogFragment 上的 onCancel() 和 onDismiss() 方法。
