I recently moved my project to Android Studio from Eclipse. I am trying to get the email functionality working, however I receive errors by "findViewById". I also receive errors by "Toast.makeText". Could you please assist on both errors. The code in my class is as follows:

```
package com.example.ishonours.witsbusapp;

import android.app.Activity;
import android.net.Uri;
import android.os.Bundle;
import android.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import android.content.Intent;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

public class ComplaintsFragment extends Fragment {

//I added
private EditText recipient;
private EditText subject;
private EditText body;

private OnFragmentInteractionListener mListener;
private static final String ARG_SECTION_NUMBER = "5";

public static ComplaintsFragment newInstance(int menuNumber) {
    ComplaintsFragment fragment = new ComplaintsFragment();
    Bundle args = new Bundle();
    args.putInt(ARG_SECTION_NUMBER, menuNumber);
    fragment.setArguments(args);
    return fragment;
}

public ComplaintsFragment() {
    // Required empty public constructor
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    return  inflater.inflate(R.layout.fragment_complaints, container, false);

    //i added
    recipient = (EditText) findViewById(R.id.recipient);
    subject = (EditText) findViewById(R.id.subject);
    body = (EditText) findViewById(R.id.body);
    Button sendBtn = (Button) findViewById(R.id.sendEmail);
    sendBtn.setOnClickListener(new View.OnClickListener() {

        public void onClick(View view) {
            sendEmail();
            // after sending the email, clear the fields
            recipient.setText("");
            subject.setText("");
            body.setText("");
        }
    });

}

//i added
protected void sendEmail() {
    String[] recipients = {recipient.getText().toString()};
    Intent email = new Intent(Intent.ACTION_SEND, Uri.parse("mailto:"));
    // prompts email clients only
    email.setType("message/rfc822");
    email.putExtra(Intent.EXTRA_EMAIL, recipients);
    email.putExtra(Intent.EXTRA_SUBJECT, subject.getText().toString());
    email.putExtra(Intent.EXTRA_TEXT, body.getText().toString());
    try {
        // the user can choose the email client
        startActivity(Intent.createChooser(email, "Choose an email client from..."));
    } catch (android.content.ActivityNotFoundException ex) {
        Toast.makeText(ComplaintsFragment.this, "No email client installed.",
               Toast.LENGTH_LONG).show();
    }}

public void onButtonPressed(Uri uri) {
    if (mListener != null) {
        mListener.onFragmentInteraction(uri);
    }
}

@Override
public void onAttach(Activity activity) {
    super.onAttach(activity);
    ((MainActivity) activity).onSectionAttached(
            getArguments().getInt(ARG_SECTION_NUMBER));
}

@Override
public void onDetach() {
    super.onDetach();
    mListener = null;
}

public interface OnFragmentInteractionListener {
    // TODO: Update argument type and name
    public void onFragmentInteraction(Uri uri);
}

```

}

The code in my xml file is:

```
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"

 android:layout_width="match_parent"

    android:layout_height="wrap_content"
    android:layout_marginBottom="20dp"
    android:gravity="center"
    android:text="Complete the fields to log a complaint"
    android:textAppearance="?android:attr/textAppearanceMedium" />

<EditText
    android:id="@+id/recipient"
