Android library activity should open independently with its own theme

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?

Solution

  • You can use below the onCreate.

     getSupportActionBar().hide()

    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>
    </style>

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

        if (getSupportActionBar() != null) {
        getSupportActionBar().hide();
    }
