Super Toolbar

Android native toolbar on steroids 💪

Summary

  • Animate the height of the toolbar as you scroll
  • Center the toolbar title horizontally
  • Use light title font

Download

This library is available in jitpack, so to use it you need to add the above statement to your root build.gradle:

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

Add the dependency:

dependencies {
    implementation 'com.github.andrefrsousa:SuperToolbar:1.3.0'
}

Sample Project

We have a sample project in Kotlin that demonstrates the use of the library here.

Use

It is recommended that you review the sample project to get a full understanding of all the features offered by the library. To display the height of the toolbar, you only need to call:

fun setElevationVisibility(show: Boolean)

If you want to have the same effect as the one used in Google Messages, for example, add a scroll listener to your RecyclerView or ScrollView. Like this:

myRecyclerView.addOnScrollListener(object : RecyclerView.OnScrollListener() {
    override fun onScrolled(recyclerView: RecyclerView, dx: Int, dy: Int) {
        super.onScrolled(recyclerView, dx, dy)
        toolbar.setElevationVisibility(recyclerView.canScrollVertically(-1))
    }
})

Adjustments

You can costumize your toolbar with the following attributes:

// The duration of the elevation animation. By default it is 250 miliseconds.
<attr name="superToolbar_animationDuration" format="integer"/>

// If you want to show the toolbar elevation when created. By default is false.
<attr name="superToolbar_showElevationAtStart" format="boolean"/>

// Center the toolbar title. Is false by default.
<attr name="superToolbar_centerTitle" format="boolean"/>

// Use a light font as the title of the toolbar. The default value is false.
<attr name="superToolbar_useLightFont" format="boolean"/>
