How to set title for action bar in android?


This example demonstrates How to set title for 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:app = "http://schemas.android.com/apk/res-auto"
   xmlns:tools = "http://schemas.android.com/tools"
   android:layout_width = "match_parent"
   android:gravity = "center"
   android:layout_height = "match_parent"
   tools:context = ".MainActivity">
   <TextView
      android:id = "@+id/text"
      android:textSize = "30sp"
      android:layout_width = "match_parent"
      android:layout_height = "match_parent" />
</LinearLayout>

package com.example.myapplication;
import android.app.ActivityManager;
import android.app.admin.DevicePolicyManager;
import android.content.ComponentName;
import android.content.Context;
import android.net.wifi.WifiInfo;
import android.net.wifi.WifiManager;
import android.os.Build;

import android.support.annotation.RequiresApi;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
   TextView textView;
   @RequiresApi(api = Build.VERSION_CODES.N)
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      textView = findViewById(R.id.text);
      getSupportActionBar().setTitle("Home");
      getSupportActionBar().setSubtitle("sairam");
      textView.setText(" tittle is Home");
   }
}
