Toolbar with two different colors

Question

How to make a Toolbar with two colors in half, going from one color to the other?

Answer 1

The name of this effect is Dégradé (gradient) or Gradient (gradient). To use a gradient at the bottom of your bar, just create an XML with its data in the Drawable folder and use it as background bar. In your case, the XML would look something like this (switch to the exact colors you want)

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <gradient
        android:startColor="#E81DCA"
        android:endColor="#7566E3"
        android:type="linear"/>
</shape>

Assuming we call the file gradiente_rosa_para_roxo.xml, the usage is like this:

<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:background="@drawable/gradiente_rosa_para_roxo"
    app:popupTheme="@style/AppTheme.PopupOverlay" />

Upshot:
