Display a DialogFragment from an Adapter RecyclerView

Navigation
1

I have a problem trying to show a Dialogfragment from an Adapter.

Normally I have done this by calling parent.Context of inflater , as follows: 

public class MiAdapter extends RecyclerView.Adapter<MiAdapter.adapterHolder>{
Context context;
List<lista> lista;

public MiAdapter (List<lista> lista){
    this.lista = lista;
}

@Override
public MiAdapter.adapterHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.rec_lista, parent, false);
    MiAdapter.adapterHolderholder = new MiAdapter.adapterHolder(v);
    context = parent.getContext();
    return holder;
}.....

The onBindViewHolder is where I show the DialogFragment after a click. 

 FragmentManager manager= ((AppCompatActivity)context).getSupportFragmentManager();
                            OtroFragment manager= new ShPerfil();                      
                            OtroFragment.show(manager, "Otro");

However, sometimes I get the following error: 

java.lang.ClassCastException: android.view.ContextThemeWrapper cannot be cast to android.support.v7.app.AppCompatActivity
                                                                       at com.miapp.Adapters.MiAdapter$1.onClick(MiAdapter.java:54)
                                                                       at android.view.View.performClick(View.java:6213)
                                                                       at android.widget.TextView.performClick(TextView.java:11074)

After investigating for a while I found something useful, the answer is in this link.

However, when implementing it, the application dies whenever I try to show DialogFragment with the following error: 

 java.lang.ClassCastException: ccom.miapp.MyContext cannot be cast to android.support.v7.app.AppCompatActivity

Could someone help me solve this problem? I do not know if I can show the DialogFragment in another way or get the Context in another way.

Thanks friends!

The solution was simpler, simply pass the Context of the Activity or the DialogFragment something like this: 

 public class MiAdapter extends RecyclerView.Adapter<MiAdapter.adapterHolder> {
Context mContext;
List<list> list;

public MiAdapter(Context context, List<list> list) {
    this.list = list;
    mContext = context;
}

to be from a DialogFragment to convert the Context to appCompatActivity.
