Cannot resolve method'setTitle(java.lang.String)'

Hi!i am on lesson "Build a Weather App",i have write all the code like the lesson but there is an error that i don't know how to fix. The error is:cannot resolve method'setTitle(java.lang.String)'at the 'setTitle' . When i put builder.setTitle all ok but in the lesson ben delete the builder and to him is all ok. Here is my code: package allyouask.com.stormy;

import android.app.AlertDialog; import android.app.Dialog; import android.app.DialogFragment; import android.content.Context; import android.os.Bundle;

/**

  • Created by Eleni on 15/5/2015. */ public class AlertDialogFragment extends DialogFragment { @Override public Dialog onCreateDialog(Bundle savedInstanceState) { Context context = getActivity(); AlertDialog.Builder builder = new AlertDialog.Builder(context); .setTitle(context.getString(R.string.error_title)) .setMessage(context.getString(R.string.error_message)) .setPositiveButton(context.getString(R.string.error_ok_button_text), null);

    AlertDialog dialog = builder.create();
return dialog;

    }

Hello,

It looks like you forgot to add on the variable name before setTitle. You currently have 

 .setTitle(context.getString(R.string.error_title)) 
.setMessage(context.getString(R.string.error_message)) 
.setPositiveButton(context.getString(R.string.error_ok_button_text), null);

If you change that to

builder.setTitle(context.getString(R.string.error_title)) 
.setMessage(context.getString(R.string.error_message)) 
.setPositiveButton(context.getString(R.string.error_ok_button_text), null);

it should get rid of the error you are having.
