What is the proper method to use the new VectorDrawable in the toolbar?
I tried to use the app:srcCompat
element as illustrated below, but nothing showed up.
<menu
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
app:srcCompat="@drawable/ic_clear"
app:showAsAction="ifRoom" />
</menu>
I have my own toolbar layout using android.support.v7.widget.Toolbar
and Android Support Library v23.2 on JB (16).
Turns out it's quite easy.
Say, you have vector drawable vd_trash_24dp
.
Describing MenuItem one cannot address VectorDrawable directly with android:icon
. It seems ignoring app:srcCompat
also.
But. As all we know ;)
AppCompat does support loading vector drawables when they are referenced in another drawable container such as a StateListDrawable, InsetDrawable, LayerDrawable, LevelListDrawable, and RotateDrawable
Let's try it, should we?
Create StateListDrawable vd_test_vd
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/vd_trash_24dp" />
</selector>
than
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools">
<item android:id="@+id/menu_action_filter"
android:title="@string/menu_action_filter"
android:icon="@drawable/vd_test_vd"
android:orderInCategory="100"
app:showAsAction="always"/>
</menu>
street magic indeed.
Yes, one could try and set drawable at runtime with MenuItem.setIcon()
. But who need that %)
