Here’s an example vector asset which we’re actually using in AppCompat:

res/drawable/ic_search.xml

<vector xmlns:android="..."
        android:width="24dp"
        android:height="24dp"
        android:viewportWidth="24.0"
        android:viewportHeight="24.0"
        android:tint="?attr/colorControlNormal">

    <path
        android:pathData="..."
        android:fillColor="@android:color/white"/>

</vector>

Using this drawable, an example ImageView declaration would be:

<ImageView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:srcCompat="@drawable/ic_search"/>

You can also set it at run-time:

ImageView iv = (ImageView) findViewById(...);
iv.setImageResource(R.drawable.ic_search);

The same attribute and calls work for ImageButton too.

Here is a simple VectorDrawable in this vectordrawable.xml file.

 <vector xmlns:android="http://schemas.android.com/apk/res/android"
     android:height="64dp"
     android:width="64dp"
     android:viewportHeight="600"
     android:viewportWidth="600" >
     <group
         android:name="rotationGroup"
         android:pivotX="300.0"
         android:pivotY="300.0"
         android:rotation="45.0" >
         <path
             android:name="v"
             android:fillColor="#000000"
             android:pathData="M300,70 l 0,-70 70,70 0,0 -70,70z" />
     </group>
 </vector>

You can import an SVG file as a VectorDrawable in Android Studio, follow these steps :

"Right-click" on the res folder and select new > Vector Asset.

Select the Local File option and browse to your .svg file. Change the options to your liking and hit next. Done.
