无法解析 RadioGroup 的方法 getText

Question

我正在尝试让用户填写表格，然后这些字段会自动填充到电子邮件中。我能够将 EditText 转换为字符串以及微调器，但我对如何使用 RadioGroup 执行此操作感到困惑。我希望所选按钮中的文本出现在电子邮件中。我知道 getText 行不通，但是什么行。谢谢

JAVA

    //This happens when you press the submit button at the bottom of the form.
    public void submit(View button) {
    // Do click handling here
    //What happens here is the input from each field is taken in and converted into
    //Strings and placed into their correct variables.

    final EditText FirstNameField = (EditText) findViewById(R.id.EditTextFirstName);
    fName = FirstNameField.getText().toString();

    final EditText LastNameField = (EditText) findViewById(R.id.EditTextLastName);
    lName = LastNameField.getText().toString();

    final EditText emailField = (EditText) findViewById(R.id.EditTextEmail);
    email = emailField.getText().toString();

    final EditText feedbackField = (EditText) findViewById(R.id.EditTextFeedbackBody);
    feedback = feedbackField.getText().toString();

    final Spinner feedbackSpinner = (Spinner) findViewById(R.id.SpinnerFeedbackType);
    feedbackType = feedbackSpinner.getSelectedItem().toString();

    final RadioGroup ApproveorReject = (RadioGroup) findViewById(R.id.radiochoice);
    fAnswer = ApproveorReject.getText().toString();


    //calls the sendEmail() from below to pull up a list of apps installed
    //on the phone that can handle emailing.
    sendEmail();
}


//This bit of code pulls up a list of apps that can handle emailing.
private void sendEmail() {

    //When the user chooses an app of the list that pops up, these lines below
    //will auto-populate the fields of the email with the input from above.
    //The user can take one last look at the email before hitting that send button
    Intent i = new Intent(Intent.ACTION_SEND);
    i.setType("message/rfc822");
    i.putExtra(Intent.EXTRA_EMAIL, new String[]{"recipient@example.com"});
    i.putExtra(Intent.EXTRA_SUBJECT, feedbackType);
    i.putExtra(Intent.EXTRA_TEXT, lName + ", " + fName + "\n" + email + "\n" + feedback + fAnswer );
    startActivity(Intent.createChooser(i, "Send mail..."));


}

}

Answer 1

试试这个

RadioButton btn=(RadioButton)findViewById(ApproveorReject.getCheckedRadioButtonId());
String selectedText=btn.getText().toString();

Answer 2

试试

 ApproveorReject.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener()
{
    public void onCheckedChanged(RadioGroup group, int checkedId) {

        RadioButton rb=(RadioButton)findViewById(checkedId);
        String param = rb.getText();
    }
});
