생성한 디렉토리에서 xml파일 생성

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:android="http://schemas.android.com/apk/res/android">

    <item
        android:id="@+id/apple"
        android:icon="@drawable/ic_launcher_background"
        android:title="사과" />
    <item

        android:title="바나나" />
    <item
        android:id="@+id/grape"
        android:icon="@drawable/ic_launcher_background"
        android:title="포도" />

</menu>

import android.view.MenuItem;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.mymenu, menu);
        return true;
    }
    @Override
    public boolean onOptionsItemSelected (MenuItem item){
        switch (item.getItemId())
        {
            case R.id.apple:
                Toast.makeText(getApplicationContext(),"사과",Toast.LENGTH_SHORT).show();
                return  true;
            case R.id.banana:
