public void backToMain(View view) {

您需要@Override onClick方法（您无法重命名）。将您的setOnClickListener方法更改为此

buttonSms.setOnClickListener  (new OnClickListener()
            {
                @Override
                public void onClick(View v)  {
                    String phoneNo = editPhoneNum;
                    String sms = textsms.getText().toString();
                    try {
                        SmsManager smsManager = SmsManager.getDefault();
                        smsManager.sendTextMessage(phoneNo, null, sms, null, null);
                        Toast.makeText(getApplicationContext(), "SMS Sent!",
                                Toast.LENGTH_LONG).show();
                    } catch (Exception e) {
                        Toast.makeText(getApplicationContext(),
                                "SMS faild, please try again later!",
                                Toast.LENGTH_LONG).show();
                        e.printStackTrace();
                    }
                }
            }
    );

将您的代码更改为此。您使用了smsclick而不是onclick

buttonSms.setOnClickListener (new OnClickListener() { 
public void onClick(View v) { 
String phoneNo = editPhoneNum;
 String sms = textsms.getText().toString(); 
try { 
SmsManager smsManager = SmsManager.getDefault();
 smsManager.sendTextMessage(phoneNo, null, sms, null, null);
 Toast.makeText(getApplicationContext(), "SMS Sent!", Toast.LENGTH_LONG).show();
 } catch (Exception e) {
 Toast.makeText(getApplicationContext(), "SMS faild, please try again later!", Toast.LENGTH_LONG).show();
 } } ); }
