Cannot resolve symbol in setOnClickListener

I have a search button in my main activity "btnSearch", whenevr I press this button I want it to take me to a new activity "search", here's the Java code that I have for this:

public class MainMenu extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main_menu);
        Button btnSearch= (Button) findViewById(R.id.btnSearch);
        btnSearch.setOnClickListener(listener);

        View.OnClickListener listener=new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent=new Intent(getApplicationContext(), Search.class);
                startActivity(intent);

            }
        };



    }
}

in the btnSearch.setOnClickListener(listener);. it gives me the error: Cannot resolve symbol 'listner'.

What should I do?

You declare the listener inside onCreate, which means it's only accessible after you initialize it. Move btnSearch.setOnClickListener after you create the listener, or move the listener declaration to the class level.

Alternatively, you can skip creating a variable entirely and just pass the listener directly:

btnSearch.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent = new Intent(getApplicationContext(), Search.class);
            startActivity(intent);

        }
    });
