HideTitleBar in Android

Introduction

This article explains how to hide the Title Bar in Android. Android Studio is used to create the sample.

TitleBar

The Title Bar contains the tilte of your application that you can set depending on your requirements. You can also hide the Title Bar using the Android manifest.xml file and also through coding.

Hide Title Bar using Java code

First we will see how to hide the Title Bar using Java code. To do that you need to call the requestWindowFeature(Window.FEATURE_NO_TITLE)  method of an Activity. But you need to call this before the setContentView( ) method of an Activity.

@Override 

    protected void onCreate(Bundle savedInstanceState) { 

        super.onCreate(savedInstanceState); 

        requestWindowFeature(Window.FEATURE_NO_TITLE); 

        setContentView(R.layout.activity_main); 

 

    } 

} 

Hide Title Bar using Android Manifest.xml file

To hide the Title Bar using the Android Manifest.xml file you need to set the Android theme to NoTitleBar like this:

android:theme="@android:style/Theme.NoTitleBar">

 

Android Manifest.xml file
 

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

    package="com.hidetitlebar"

    android:versionCode="1"

    android:versionName="1.0" >

 

    <uses-sdk

        android:minSdkVersion="7"

        android:targetSdkVersion="16" />

 

    <application

        android:allowBackup="true"

        android:icon="@drawable/ic_launcher"

        android:label="@string/app_name"

        android:theme="@style/AppTheme" >

        <activity

            android:name="com.hidetitlebar.MainActivity"

            android:label="@string/app_name"

            android:theme="@android:style/Theme.NoTitleBar">

 

            <intent-filter>

                <action android:name="android.intent.action.MAIN" />

 

                <category android:name="android.intent.category.LAUNCHER" />

            </intent-filter>

        </activity>

    </application>

 

</manifest>

Step 1

Create a project like this:



Step 2

Create an XML file with the following:
 

<RelativeLayout 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"

    android:paddingBottom="@dimen/activity_vertical_margin"

    android:paddingLeft="@dimen/activity_horizontal_margin"

    android:paddingRight="@dimen/activity_horizontal_margin"

    android:paddingTop="@dimen/activity_vertical_margin"

    tools:context=".MainActivity"

    android:background="#d155">

 

    <TextView

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:text="Hide Title Bar"

        android:textSize="40dp"

        android:layout_centerInParent="true"/>

 

</RelativeLayout>

Step 3

Create a Java class file with the following.

In this you will  hide the Title Bar by calling the requestWindowFeature(Window.FEATURE_NO_TITLE)  method of an Activity. But you need to call this before the setContentView( ) method of an Activity.
 

package com.hidetitlebar;

import android.os.Bundle;

import android.app.Activity;

import android.view.Menu;

import android.view.Window;

import android.view.WindowManager;

 

public class MainActivity extends Activity {

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        requestWindowFeature(Window.FEATURE_NO_TITLE);

     

      //     WindowManager.LayoutParams.FLAG_FULLSCREEN);//int flag, int mask

     

        setContentView(R.layout.activity_main);

    }

}

Step 4

Android Manifest.xml file
 

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

    package="com.hidetitlebar"

    android:versionCode="1"

    android:versionName="1.0" >

    <uses-sdk

        android:minSdkVersion="7"

        android:targetSdkVersion="16" />

 

    <application

        android:allowBackup="true"

        android:icon="@drawable/ic_launcher"

        android:label="@string/app_name"

        android:theme="@style/AppTheme" >

        <activity

            android:name="com.hidetitlebar.MainActivity"

            android:label="@string/app_name"

           >

            <intent-filter>

                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />

            </intent-filter>

        </activity>

    </application>

</manifest>
