Standard CollapsingToolbarLayout with subtitle support. Using internal components of support design library allows it to behave similarly to its sibling CollapsingToolbarLayout, while also ensuring minimum library size.

Download

This library follows AndroidX's revisions.

repositories {
    google()
    jcenter()
}

dependencies {
    implementation "com.google.android.material:material:$version"

}
