You can try to this code..

Mainactivity.java

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.activity_main);

  }
}

Main.xml 

<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="match_parent"
android:background="@android:color/holo_orange_light"    
android:orientation="vertical">

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="50dp"
    android:background="@android:color/holo_orange_light">

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:gravity="center"
        android:text="Home Activity"
        android:textSize="20sp" />
</LinearLayout>

and style.xml

  <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

You can access that BLUE BAR as per your requirement from the "Styles" resource file. You Can change colour, theme, style etc as per ur need. Go to XML files, Click:-

res -> values -> styles.

You need to hide the action bar. The simplest way to do that is to add a style in the style.xml file. Something like this:

<resources>
    <!-- No action bar theme -->
    <style name="NoActionBar" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="colorPrimary">@color/blueDark</item>
        <item name="colorPrimaryDark">@color/blueDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>
</resources>

Did you notice the parent? "NoActionBar". And then in your manifest change the theme of your activity:

<activity
        android:name="your.package.name.YourActivity"
        android:label="@string/application_name"
        android:theme="@style/NoActionBar" />

requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);

Add these lines before setContentView
