Make Toolbar transparent

Question

create_account.xml

Answer 1

That is my version of how to get the transparent Toolbar without shadow in AppBarLayout. The major problem with the above solutions was when I made the toolbar transparent, the shadow was still cast under it. To make the transparent toolbar with the back navigationIcon in Fragment:

layout_transparent_toolbar_fragment.xml:

and in TransparentToolbarFragment:

override fun onCreateView(inflater: LayoutInflater, vg: ViewGroup?, savedInstanceState: Bundle?): View? {
    val layout = inflater.inflate(R.layout.layout_transparent_toolbar_fragment, vg, false)
    val toolbar = layout.findViewById(R.id.toolbar) as Toolbar
    val appBar = layout.findViewById(R.id.general_appbar) as AppBarLayout
    appBar.outlineProvider = null
    val appCompatActivity = (activity as AppCompatActivity)
    appCompatActivity.setSupportActionBar(toolbar)

    val actionBar = appCompatActivity.getSupportActionBar()
    if (actionBar != null) actionBar!!.setDisplayHomeAsUpEnabled(true)
    toolbar.setNavigationOnClickListener { appCompatActivity.finish() }

    return layout
}

Actually, the line

appBar.outlineProvider = null

does the job of hiding the toolbar shadow.
