 protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_template1);
        Toolbar toolbar = findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);



        cvPhoto = findViewById(R.id.photo);
        cvName = findViewById(R.id.user_name);
        cvName2 = findViewById(R.id.user_name2);
        cvBirthDate = findViewById(R.id.user_date);
        cvAddress = findViewById(R.id.user_address);
        cvNationality = findViewById(R.id.user_nationality);
        cvPhone = findViewById(R.id.user_contact);
        cvEmail = findViewById(R.id.user_email);
        cvSchool = findViewById(R.id.user_school);
        cvSpecialty = findViewById(R.id.user_specialty);
        cvCertificate = findViewById(R.id.user_certificate);
        cvYear = findViewById(R.id.user_years);
        cvCompany= findViewById(R.id.user_company);
        cvPost = findViewById(R.id.user_post);
        cvDuration= findViewById(R.id.user_duration);
        cvReference= findViewById(R.id.user_reference);
        cvLanguage = findViewById(R.id.user_language);
        cvOthers= findViewById(R.id.user_skill);
        cvDate = findViewById(R.id.current_date);



        Date date = new Date();
        String modifiedDate = new SimpleDateFormat(" dd MMM, yyyy", Locale.getDefault()).format(new Date());
        cvDate.setText(getString(R.string.done_on) + " " + modifiedDate);

        Intent intent = getIntent();
        Bundle bundle = getIntent().getExtras();


        final String tname =bundle.getString("user_name");
        final String tbirtDate =bundle.getString("user_date_of_birth");
        final String  taddress =bundle.getString("user_address");
        final String tnationality =bundle.getString("user_nationality");
        final String temail =bundle.getString("user_email");
        final String tphone =bundle.getString("user_phone");
        final String tschool =bundle.getString("user_school");
        final String tspecialty =bundle.getString("user_specialty");
        final String tcertificate =bundle.getString("user_certificate");
        final String tyears =bundle.getString("user_years");
        final String tcompany =bundle.getString("user_company");
        final String tpost =bundle.getString("user_post");
        final String tduration =bundle.getString("user_duration");
        final String treference =bundle.getString("user_reference");
        final String tlanguages =bundle.getString("user_languages");
        final String totherSkills =bundle.getString("user_other_skills");

        Bitmap resized = intent.getParcelableExtra("BitmapImage");

        cvPhoto.setImageBitmap(resized);

        cvName.setText(getString(R.string.full_name) +" "+ tname);
        cvBirthDate.setText(getString(R.string.date_of_birth) +" "+ tbirtDate);
        cvAddress.setText(getString(R.string.address) +" "+ taddress);
        cvNationality.setText(getString(R.string.nationality) +" "+ tnationality);
        cvEmail.setText(getString(R.string.email) +" "+ temail);
        cvPhone.setText(getString(R.string.phone_number) +" "+ tphone);
        cvSchool.setText(getString(R.string.school_attended) +"\n "+ tschool);
        cvSpecialty.setText(getString(R.string.specialty_course) +"\n "+ tspecialty);
        cvCertificate.setText(getString(R.string.certificates_obtained) +"\n "+ tcertificate);

        cvReference.setText(getString(R.string.reference) +"\n "+ treference);
        cvLanguage.setText(tlanguages);
        cvOthers.setText(totherSkills);
        cvName2.setText(tname);

And here is the code to create the pdf document with the activity:

   FloatingActionButton fab = findViewById(R.id.fab);
        fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {


                    PdfDocument document = new PdfDocument();

                PdfDocument.PageInfo pageInfo = new PdfDocument.PageInfo.Builder(2250, 1400, 1).create();

                // start a page

                PdfDocument.Page page = document.startPage(pageInfo);


                // add something on the page
                LayoutInflater inflater = (LayoutInflater)
                        getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                View content = inflater.inflate(R.layout.activity_template1, null);

                content.measure(1400, 2250);
                content.layout(0,0, 2250, 1400);


                content.draw(page.getCanvas());

                // finish the page
                document.finishPage(page);
                // add more pages

                // write the document content
                String directory_path = Environment.getExternalStorageDirectory().getPath() + "/mypdf/";
                File file = new File(directory_path);
                if (!file.exists()) {
                    file.mkdirs();
                }
                String targetPdf = directory_path+"My CV.pdf";
                File filePath = new File(targetPdf);
                try {
                    document.writeTo(new FileOutputStream(filePath));
                    Toast.makeText(Template1Activity.this, "Done", Toast.LENGTH_LONG).show();
                } catch (IOException e) {
                    Log.e("main", "error "+e.toString());
                    Toast.makeText(Template1Activity.this, "Something wrong: " + e.toString(),  Toast.LENGTH_LONG).show();
                }
                // close the document
                document.close();

The end result only gives me the activity without the data.

Since you've not specified how you want to generate your pdf, you can look into PdfDocument class that comes with the android sdk.

Make sure you have android.permission.WRITE_EXTERNAL_STORAGE permission

Pass the parent view to createPdfFromView

 private void createPdfFromView(View view, String fileName, int pageWidth, int pageHeight, int pageNumber) {

        File path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOCUMENTS);
        File file = new File(path, fileName.concat(".pdf"));

        FileOutputStream fOut = null;
        try {
            fOut = new FileOutputStream(file);
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }

        try {
            file.createNewFile();
        } catch (IOException e) {
            e.printStackTrace();
        }

        if (file.exists()) {
            PdfDocument document = new PdfDocument();
            PdfDocument.PageInfo pageInfo = new PdfDocument.PageInfo.Builder(pageWidth, pageHeight, pageNumber).create();
            PdfDocument.Page page = document.startPage(pageInfo);

            view.draw(page.getCanvas());

            document.finishPage(page);

            try {
                Toast.makeText(this, "Saving...", Toast.LENGTH_SHORT).show();
                document.writeTo(fOut);
            } catch (IOException e) {
                Toast.makeText(this, "Failed...", Toast.LENGTH_SHORT).show();
                e.printStackTrace();
            }

            document.close();

            /*Intent intent = new Intent(Intent.ACTION_VIEW);
            intent.setDataAndType(Uri.fromFile(file), "application/pdf");
            intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
            startActivity(intent);*/

        } else {
            //..
        }

    }

Answer 2

Better use eg. Apache PDFbox and render the CV in DIN A4 or US Letter format.

Else that would be a PDF with a screenshot inside, which is not machine-readable.

PDF/A-3 might also be an option, if only there was a standardized CV XML format.
