Cannot Resolve my CompundButton buttonview for Switch button

Question

I am trying to disable EditText if Switch is off I have made If-else for it. But my CompoundButton buttonView cannot be resolved. What can be the issue? Here's my code:

public class MainActivity extends AppCompatActivity {

        public static final String EXTRA_MESSAGE = "com.example.myfirstapp.MESSAGE";
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
        }
        EditText editText = (EditText) findViewById(R.id.editText);
        /** Called when the user taps the Send button */
        public void sendMessage(View view) {
            // Do something in response to button
            Intent newxml = new Intent(this, DisplayMessageActivity.class);
            String message = editText.getText().toString();
            newxml.putExtra(EXTRA_MESSAGE, message);
            startActivity(newxml);
            TextView displayText = (TextView) findViewById(R.id.displayText);
            displayText.setText(message);
            String someText = "Your Message";
            TextView yourMessage = (TextView) findViewById(R.id.yourMessage);
            yourMessage.setText(someText);
        }
        final Switch switch1 = (Switch) findViewById(R.id.switch1);
        switch1.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                // true if the switch is in the On position
                if(isChecked){
                    editText.setFocusableInTouchMode(true);
                    editText.setFocusable(true);
                }else{
                    editText.setFocusableInTouchMode(false);
                    editText.setFocusable(false);
                }
            }
        });
    }

You may alspo go through these error links if the error is same https://stackoverflow.com/a/44413351/2641380 or https://stackoverflow.com/q/29844990/2641380 — SHS, Dec 01 '18 at 05:29
good, you may have found the error. shift code of --> final Switch switch1 ... and it's onChackedChanged listener code inside onCreate(). If you are not using switch1 variable at any other places, this could work. — SHS, Dec 01 '18 at 05:41

I have rewritten the portion of code below. You may try it at your end.

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        final Switch switch1 = (Switch) findViewById(R.id.switch1);
        switch1.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                // true if the switch is in the On position
                if(isChecked){
                    editText.setFocusableInTouchMode(true);
                    editText.setFocusable(true);
                }else{
                    editText.setFocusableInTouchMode(false);
                    editText.setFocusable(false);
                }
            }
        });

    }

..... then other code.

I solved it buddy and your code worked thanks for your efforts — Yash, Dec 01 '18 at 06:16
