1. open styles.xml

 <style name="no_title" parent="AppTheme">
        <item name="android:windowNoTitle">true</item>
        <item name="android:windowContentOverlay">@null</item>
 </style>

you can change name="---------"

3. open Androidmaifest.xm

   find android:theme="@style/AppTheme" chang to android:theme="@style/no_title"

4. click select Theme on menubar (it's green color near MainActivity)

   • click project Theme
   • click no_title (on you right hand Side)
   • click OK

Answer 2

To simply remove the title bar (which means the bar contains your app name) from an activity, I simply add below line to that activity in the manifests\AndroidManifest.xml:

android:theme="@style/AppTheme.NoActionBar"

It should now look like below

<activity
  android:name=".MyActivity"
  android:theme="@style/AppTheme.NoActionBar"></activity>

Hope it'll be useful.

 ActionBar actionBar = getSupportActionBar();
    actionBar.hide();

Answer 4

in onCreate() works!

Answer 5

For Beginner Like Me. Just Do it what I say.From your Android Project.

app -> res -> values -> style.xml

replace this code

<resources>

<!-- Base application theme. -->
<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>

</resources>

Enjoy.

Answer 6

In AndroidManifest.xml of your application you'll find the android:theme for example set to @style/AppTheme

Now go to styles.xml, find the style tag, make sure that name is set to AppTheme the same as in manifest and set parent to android:Theme.Holo.Light.NoActionBar (also do this in styles(v21) if you have it in your project)

<style name="AppTheme" parent="android:Theme.Holo.Light.NoActionBar">
    <!-- ... -->
</style>
