How do I remove the title bar in Android studio with  example

In this lesson describes how to hide the status bar on different versions of Android. Hiding the status bar (and optionally, the navigation bar) lets the content use more of the display space, thereby providing a more immersive user experience.

Method: One

Figure: 1 shows an app with a visible status bar:

Add new theme style with no action bar in your and set. styles.xmlparent="Theme.AppCompat.NoActionBar"

1 2 3 4 5 6 7 8

<style name="SplashTheme" parent="Theme.AppCompat.NoActionBar">       <item name="colorPrimary">@color/colorPrimary</item>     <item name="colorPrimaryDark">@color/colorPrimary</item>     <item name="colorAccent">@color/colorAccent</item>     <item name="android:windowBackground">@color/colorPrimary</item>   </style>

Figure:2 Hidden status bar.

The advantages of using an activity theme are as follows:

• It’s easier to maintain and less error-prone than setting a flag programmatically.
• It results in smoother UI transitions because the system has the information it needs to render your UI before instantiating your app’s main activity.

Method: Two

Android hide action bar programmatically

When you hide title bar then you can add this code in a java class

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

package raman.eduandroid.com.hidetitlebar;      import android.support.v7.app.AppCompatActivity;   import android.os.Bundle;   import android.view.Window;   import android.view.WindowManager;      public class MainActivity extends AppCompatActivity {          @Override       protected void onCreate(Bundle savedInstanceState) {           super.onCreate(savedInstanceState);           requestWindowFeature(Window.FEATURE_NO_TITLE); //will hide the title           getSupportActionBar().hide(); // hide the title bar           this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,                  WindowManager.LayoutParams.FLAG_FULLSCREEN); //enable full screen           setContentView(R.layout.activity_main);
