How to use VectorDrawables in Android?

To use VectorDrawables in an Android app, follow these steps:

  1. Add VectorDrawable Support:

    To use VectorDrawables in your Android app, make sure you have the following dependencies in your app-level build.gradle file:

    android { defaultConfig { vectorDrawables.useSupportLibrary = true } } dependencies { implementation 'androidx.appcompat:appcompat:1.4.0' // Or the latest version }

    Setting vectorDrawables.useSupportLibrary to true enables support for VectorDrawables on pre-Lollipop (API level 21) devices. The appcompat library is used for compatibility.

  2. Add a VectorDrawable Resource:

    Create a VectorDrawable XML file in the res/drawable directory. You can create this file manually or by right-clicking the res/drawable directory in Android Studio and selecting "Vector Asset."

    For example, let's create a simple vector drawable named ic_android.xml with an Android robot icon:

    <vector xmlns:android="http://schemas.android.com/apk/res/android" android:width="24dp" android:height="24dp" android:viewportWidth="24" android:viewportHeight="24"> <path android:fillColor="#FF000000" android:pathData="M12,2C6.48,2 2,6.48 2,12s4.48,10 10,10 10-4.48 10-10S17.52,2 12,2zm0,18c-4.41,0-8-3.59-8-8s3.59-8 8-8 8,3.59 8,8-3.59,8-8,8zm-1-12h2v4h-2zm0,6h2v2h-2z"/> </vector>

  3. Display the VectorDrawable:

    You can display the VectorDrawable in your app by using an ImageView or any other view that supports drawable resources.

    For example, to display the ic_android VectorDrawable in an ImageView:

    <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/ic_android" android:contentDescription="Android Icon"/>

    The android:src attribute references the ic_android VectorDrawable resource.

  4. Build and Run:

    Build and run your Android app, and you should see the VectorDrawable displayed in the specified ImageView or view.

VectorDrawables are a great way to include scalable vector graphics in your Android app, and they automatically adapt to different screen densities and sizes, providing a consistent and sharp look across various devices.
