How to create custom actionbar in android?


Before getting into example we should know what is action bar in android. Action bar just like header in android. Either we can use same action bar for all screen or we can change action bar for particular activity.

This example demonstrate about how to create a custom action bar in Android.

Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.

Step 2 − Add the following code to res/layout/activity_main.xml.

<?xml version = "1.0" encoding = "utf-8"?>
<LinearLayout xmlns:android = "http://schemas.android.com/apk/res/android"
   xmlns:tools = "http://schemas.android.com/tools"
   android:layout_width = "match_parent"
   android:layout_height = "match_parent"
   tools:context = ".MainActivity">
   <TextView
      android:layout_width = "wrap_content"
      android:layout_height = "wrap_content"
      android:text = "Custom Action Bar"
      android:textSize = "20sp"/>
</LinearLayout>

Step 2 − Add the following code to src/MainActivity.java

import android.os.Bundle;
import android.support.v7.app.ActionBar;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.TextView;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity {
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      this.getSupportActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);
      getSupportActionBar().setDisplayShowCustomEnabled(true);
      getSupportActionBar().setCustomView(R.layout.custom_action_bar);
      //getSupportActionBar().setElevation(0);
      View view = getSupportActionBar().getCustomView();
      TextView name = view.findViewById(R.id.name);
      name.setOnClickListener(new View.OnClickListener() {
         @Override
         public void onClick(View v) {
            Toast.makeText(MainActivity.this, "You have clicked tittle", Toast.LENGTH_LONG).show();
         }
      });
   }
}

Step 3 − Create a layout for action bar in res folder as custom_action_bar.xml shown below

<?xml version = "1.0" encoding = "utf-8"?>
<LinearLayout xmlns:android = "http://schemas.android.com/apk/res/android"
   xmlns:app = "http://schemas.android.com/apk/res-auto"
   android:layout_width = "match_parent"
   android:layout_height = "wrap_content"
   android:gravity = "center_vertical"
   android:padding = "10dp"
   android:weightSum = "1">
   <LinearLayout
      android:layout_width = "0dp"
      android:layout_height = "match_parent"
      android:layout_weight = "0.6">
      <ImageView
         android:layout_width = "wrap_content"
         android:layout_height = "match_parent"
         android:src = "@drawable/ic_face_red_400_24dp" />
      <TextView
         android:id = "@+id/name"
         android:layout_width = "match_parent"
         android:layout_height = "wrap_content"
         android:layout_marginLeft = "10dp"
         android:text = "Instagram"
         android:textSize = "20sp"
         android:textColor = "#000"
         android:textStyle = "bold"
         app:fontFamily = "@font/allan_bold" />
   </LinearLayout>
   <LinearLayout
      android:layout_width = "0dp"
      android:layout_height = "match_parent"
      android:layout_marginRight = "10dp"
      android:layout_weight = "0.4"
      android:gravity = "end">
   <ImageView
      android:layout_width = "wrap_content"
      android:layout_height = "match_parent"
      android:src = "@drawable/ic_local_post_office_red_400_24dp" />
   <ImageView
      android:layout_width = "wrap_content"
      android:layout_height = "match_parent"
      android:layout_marginLeft = "20dp"
      android:src = "@drawable/ic_send_red_400_24dp" />
   </LinearLayout>
</LinearLayout>

Note − According to the project / application specification we need to change the custom layout.
