MainActivity.java

import androidx.appcompat.app.ActionBar;
import androidx.appcompat.app.AppCompatActivity;
import androidx.appcompat.widget.SearchView;

import android.content.Context;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.Toast;

import com.example.actionbar.databinding.ActivityMainBinding;

public class MainActivity extends AppCompatActivity {

    private ActivityMainBinding binding;
    public Context mContext;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        binding = ActivityMainBinding.inflate(getLayoutInflater());
        setContentView(binding.getRoot());

        ActionBar actionBar = getSupportActionBar();
        actionBar.setTitle("액션바 서치기능 활성화");
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {

        mContext = getApplicationContext();
        getMenuInflater().inflate(R.menu.actionbar_menu, menu);

        SearchView searchView = (SearchView)menu.findItem(R.id.menuSearch).getActionView();
        searchView.setMaxWidth(Integer.MAX_VALUE);
        searchView.setQueryHint("검색어를 입력합니다.");

        searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener(){

            // 검색어 입력중 이벤트 제어
            @Override
            public boolean onQueryTextChange(String msg) {
                // Toast.makeText(getApplicationContext(), "입력중입니다.", Toast.LENGTH_SHORT).show();
                return false;
            }

            // 검색어 완료시 이벤트 제어
            @Override
            public boolean onQueryTextSubmit(String msg) {
                Toast.makeText(getApplicationContext(), msg, Toast.LENGTH_SHORT).show();
                return false;
            }
        });

        return true;
    }
