Can we to use the single Action Bar for all Activities?

I have Action bar and a lot of different Activity, its working, but I don't want to add code in every Activity. How to add one code in one Activity that will work in every Activity? I expect to write only one code in one Activity for all activities.

My main activity:

package ua.in.masterpc.technoguide;

import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.View;
import android.widget.ImageButton;

public class IconsMain extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_icons_main);

    ImageButton myImageButton = findViewById(R.id.iconPC);
  myImageButton.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View v) {
          Intent intentLoadNewActivity = new Intent(IconsMain.this, PCProblems.class);
          startActivity(intentLoadNewActivity);
      }
  });
    }

@Override//start menu code
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.bar_menu, menu);
    return true;
    }//end menu code
}

Thank you for answers!

  1. Create a layout say, toolbar_layout, and add the the code for your layout, then include the layout in all your activities:

create a baseActivity add function inside it to initialize the toolbar and customize it as you like 

open class BaseActivity : AppCompatActivity() {
 protected fun initializeToolbar() {
 val toolbar: Toolbar = findViewById(R.id.toolbar)
        setSupportActionBar(toolbar)
   }
}

create toolbar_main.xml

extends the baseActivity in any activty after including the toolbar_main.xml as <include layout="@layout/toolbar_main" />

class MainActivity : BaseActivity(){
}

and call the function you created in baseActivity.

You can create class named BaseActivity which will extend AppCompatActivity and put there the code and functionality you want to use in every other Activity. Then in every of your activities, you will extend BaseActivity instead of AppCompatActivity. By doing that you can avoid duplicating your code. Remember that you will have to put ActionBar in every activity .xml layout file.
