I want to create my own library, which contains common functionality flow. So that it can used in multiple apps at runtime, by just importing my library.

I am following Android developer guide and some examples to create library.

I am defining theme for my library is Theme.AppCompat.Light.NoActionBar.

Application using my library having defined theme is Theme.AppCompat.Light.DarkActionBar.

So my problem is: when user call action to open my library, library should open without action bar, but it open below the Application action bar/toolbar.

I am adding image, which will describe my actual problem:

enter image description here

Is there any setting which will help me to open my library with my defined theme?


You can use below the onCreate.


In styles.xml similar to this:

   <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>

Note:- Need to add below condition, in case of library. Because some application might already have NoActionBar theme.

    if (getSupportActionBar() != null) {
