Java 将数据发送到电子邮件的复选框

我最近一直在努力解决将复选框数据传输到电子邮件的问题。 我组合了edittext框，通过按submit，所有这些edittext的数据都会传输到电子邮件中。如何在intent.putExtra（intent.EXTRA_TEXT）中包含复选框？我的代码如下：

button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            if (!editTextTextPersonName4.getText().toString().isEmpty() && !editTextTextPersonName5.getText().toString().isEmpty()
                    && !editTextTextPersonName6.getText().toString().isEmpty() && !editTextTextPersonName7.getText().toString().isEmpty()  && !editTextTextPersonName8.getText().toString().isEmpty()) {
                Intent intent = new Intent(Intent.ACTION_SENDTO);
                intent.setData(Uri.parse("mailto:")); // only email apps should handle this.
                intent.putExtra(Intent.EXTRA_EMAIL, "");
                intent.putExtra(Intent.EXTRA_SUBJECT, "Email for Mercedes Autoteile");
                intent.putExtra(Intent.EXTRA_TEXT, "Name: " + editTextTextPersonName4.getText().toString() + '\n' + "Surname: " + editTextTextPersonName5.getText().toString() + '\n' + "Email: " + editTextTextPersonName6.getText().toString() + '\n' + "Cellphone Number: "
                        + editTextTextPersonName7.getText().toString() + '\n' + "VIN Number: " + editTextTextPersonName8.getText().toString() + '\n' + "Non Listed Part(s): " + editTextTextPersonName.getText().toString());
