Remove app title bar android

Question

I know this question has been asked million times but whichever method I use is not good for me.

If I use

android:theme=\"@android:style/Theme.NoTit         


        

Answer 1

If you add the theme to the application, it applies to the whole app.

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

You have to add it to the activity declaration.

<activity
    android:name=".YourActivity"
    android:theme="@android:style/Theme.NoTitleBar"/>

Answer 2

This is what worked for me

 android:theme="@style/Theme.AppCompat.NoActionBar">

Answer 3

For android 8 and above support. Use this in your app theme file. I've modified my default in res/styles.xml :

<style name="AppTheme" parent="Theme.AppCompat.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="android:windowNoTitle">true</item>
    <item name="android:background">@color/white</item>
</style>
