使用AndroidX库在某个Activity中打开DialogFragment，还可以吗？

Question

我有一个Activity，我需要在这个Activity中打开一个DialogFragment，以前使用just.DialogFragment是可以的。

if(ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED){
            if(ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.ACCESS_FINE_LOCATION)){
                FragmentManager fragmentManager = getSupportFragmentManager();
                InfoLocalizacao infoLocalizacao = new InfoLocalizacao();
                infoLocalizacao.show(fragmentManager, "InfoLocalizacao");"InfoLocalizacao");
            ...

使用这个方法只需要使用FragmentManager对象，但是，目前，这个方法返回这个。

java.lang.IllegalStateException: Fragment com.example.agrolucros2019.frags_e_actvs.venda.AddAnuncioActivity.InfoLocalizacao must be a public static class to be  properly recreated from instance state.

这是我的DialogFragment代码。

public class InfoLocalizacao extends DialogFragment{
        @NotNull
        public Dialog onCreateDialog(Bundle savedInstanceState){

            AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
            builder.setTitle("A Localização é importante");
            builder.setIcon(R.drawable.ic_location_on_24dp);
            builder.setMessage(R.string.avisoVenda)
                    .setPositiveButton("Estou Ciente", new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int id) {
                            Toast.makeText(getApplicationContext(), ":)", Toast.LENGTH_SHORT).show();
                        }
                    });
            return builder.create();
        }
    }

到现在为止，我得到的是让InfoLocalizacao类成为静态的，它工作得很好，但是，对于静态的类，我不能使用非静态的方法，比如Toast.makeText，我不得不从我的代码中删除。

保持这样的。

public static class InfoLocalizacao extends DialogFragment{
    @NotNull
    public Dialog onCreateDialog(Bundle savedInstanceState){

        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
        builder.setTitle("A Localização é importante");
        builder.setIcon(R.drawable.ic_location_on_24dp);
        builder.setMessage(R.string.avisoVenda)
                .setPositiveButton("Estou Ciente", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int id) {
                        //Toast.makeText(getApplicationContext(), ":)", Toast.LENGTH_SHORT).show();
                    }
                });
        return builder.create();
    }
}
