Question

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.EditText;


/**
 * A simple {@link Fragment} subclass.
 */
public class send extends Fragment {

    private EditText mEditTextTo;
    private EditText mEditTextSubject;
    private EditText mEditTextMessage;


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


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


        mEditTextTo = findViewById(R.id.edit_text_to);
        mEditTextSubject = findViewById(R.id.edit_text_subject); 
       //Cannot resolve method 'findViewById' in all find view by id 
        mEditTextMessage = findViewById(R.id.edit_text_message);

        Button buttonSend = findViewById(R.id.button_send);
        buttonSend.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                sendMail();
            }
        });
    }

    private void sendMail() {
        String recipientList = mEditTextTo.getText().toString();
        String[] recipients = recipientList.split(",");

        String subject = mEditTextSubject.getText().toString();
        String message = mEditTextMessage.getText().toString();

You're returning from `onCreateView(..)` on the very first line. The code below that `return` will not execute. Also, the issues with `findViewById` is that you need to find the id on some root view first. So, do `view.findViewById` — denvercoder9, Sep 22 '19 at 11:19

You can not directly call findViewById in fragment. For this you have to implement onViewCreated method, this will return view and u can use this view to call findViewById method.

   @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View view = LayoutInflater.from(getActivity()).inflate(R.layout.fragment_send, container, false);
        return view;
    }

     @Override
    public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);

        mEditTextTo = view.findViewById(R.id.edit_text_to);
        mEditTextSubject = view.findViewById(R.id.edit_text_subject); 
        mEditTextMessage = view.findViewById(R.id.edit_text_message);
        Button buttonSend = view.findViewById(R.id.button_send);
}

Init

mEditTextTo = view.findViewById(R.id.edit_text_to);
        mEditTextSubject = view.findViewById(R.id.edit_text_subject);

inside onViewCreated().

In onCreateView after return statement, it is not allowed as per return

First of all, you have written findViewById after return statement, so it will never be executed.

Your fragment should be like this

import android.content.Intent;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.EditText;


/**
 * A simple {@link Fragment} subclass.
 */
public class Send extends Fragment {

    private EditText mEditTextTo;
    private EditText mEditTextSubject;
    private EditText mEditTextMessage;


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


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

    @Override
    public View onViewCreated(View view, @Nullable Bundle savedInstanceState) {

        mEditTextTo = view.findViewById(R.id.edit_text_to);
        mEditTextSubject = view.findViewById(R.id.edit_text_subject); 
        mEditTextMessage = view.findViewById(R.id.edit_text_message);

        Button buttonSend = view.findViewById(R.id.button_send);
        buttonSend.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                sendMail();
            }
        });
    }

    private void sendMail() {
        String recipientList = mEditTextTo.getText().toString();
        String[] recipients = recipientList.split(",");

        String subject = mEditTextSubject.getText().toString();
        String message = mEditTextMessage.getText().toString();

        Intent intent = new Intent(Intent.ACTION_SEND);
        intent.putExtra(Intent.EXTRA_EMAIL, recipients);
        intent.putExtra(Intent.EXTRA_SUBJECT, subject);
        intent.putExtra(Intent.EXTRA_TEXT, message);

        intent.setType("message/rfc822");
        startActivity(Intent.createChooser(intent, "Choose an email client"));
    }
}

@JamesLogan Can you add your `fragment_send.xml` and the error logs? — Maddy, Sep 24 '19 at 04:09
@JamesLogan avoid asking multiple questions at the same time, it seems you have changed the actually question, previously it was regarding layout and now its about NavDrawer. to ask a good question you can check [this](https://stackoverflow.com/help/how-to-ask) — Maddy, Sep 24 '19 at 09:03
