You can use the following method:

<pre class="lang-java prettyprint-override"><code>@TargetApi(Build.VERSION_CODES.LOLLIPOP)
private static Bitmap getBitmap(VectorDrawable vectorDrawable) {
 Bitmap bitmap = Bitmap.createBitmap(vectorDrawable.getIntrinsicWidth(),

 Canvas canvas = new Canvas(bitmap);
 vectorDrawable.setBounds(0, 0, canvas.getWidth(), canvas.getHeight());
 vectorDrawable.draw(canvas);
 return bitmap;
}
</code></pre>

which I sometimes combine with:

<pre class="lang-java prettyprint-override"><code>private static Bitmap getBitmap(Context context, int drawableId) {
 Drawable drawable = ContextCompat.getDrawable(context, drawableId);
 if (drawable instanceof BitmapDrawable) {
 return ((BitmapDrawable) drawable).getBitmap();

 return getBitmap((VectorDrawable) drawable);
 } else {
 throw new IllegalArgumentException("unsupported drawable type");

}

Based on the previous answers it can be simplified like that to match both VectorDrawable and BitmapDrawable and to be compatible with at least API 15.
<pre><code>public static Bitmap getBitmapFromDrawable(Context context, @DrawableRes int drawableId) {
 Drawable drawable = AppCompatResources.getDrawable(context, drawableId);

 if (drawable instanceof BitmapDrawable) {
 return ((BitmapDrawable) drawable).getBitmap();
 } else if (drawable instanceof VectorDrawableCompat || drawable instanceof VectorDrawable) {
 Bitmap bitmap = Bitmap.createBitmap(drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight(), Bitmap.Config.ARGB_8888);
 Canvas canvas = new Canvas(bitmap);
 drawable.setBounds(0, 0, canvas.getWidth(), canvas.getHeight());
 drawable.draw(canvas);

 return bitmap;
 } else {
 throw new IllegalArgumentException(&quot;unsupported drawable type&quot;);
 }
}
</code></pre>
Then you have to add in your gradle file:
<pre><code>android {
 defaultConfig {
 vectorDrawables.useSupportLibrary = true
 }
}
</code></pre>
On pre-Lollipop it will use VectorDrawableCompat and on Lollipop it will use VectorDrawable.
<h2>EDIT</h2>
I've edited the condition following the comment of @user3109468
<h2>EDIT 2 (10/2020)</h2>
At least from API 21 you can now use this instead of the above code (I haven't tried on previous API versions):

Here is the <code>Kotlin</code> version using extensions to <code>Context</code>

<pre><code>fun Context.getBitmapFromVectorDrawable(drawableId: Int): Bitmap? {
 var drawable = ContextCompat.getDrawable(this, drawableId) ?: return null

 if (Build.VERSION.SDK_INT &lt; Build.VERSION_CODES.LOLLIPOP) {

 }

 val bitmap = Bitmap.createBitmap(
 drawable.intrinsicWidth,
 drawable.intrinsicHeight,
 Bitmap.Config.ARGB_8888) ?: return null
 val canvas = Canvas(bitmap)
 drawable.setBounds(0, 0, canvas.width, canvas.height)
 drawable.draw(canvas)

 return bitmap
}
</code></pre>

Example usage in <code>Activity</code>:

<pre><code>val bitmap = this.getBitmapFromVectorDrawable(R.drawable.ic_done_white_24dp)

If you are willing to use <a href="https://android.googlesource.com/platform/frameworks/support/" rel="noreferrer">Android KTX</a> for Kotlin you can use the extension method <code>Drawable#toBitmap()</code> to achieve the same effect as the other answers:

<pre><code>val bitmap = AppCompatResources.getDrawable(requireContext(), drawableId).toBitmap() 
</code></pre>

or 

<pre><code>val bitmap = AppCompatResources.getDrawable(context, drawableId).toBitmap() 
</code></pre>

To add this and other useful extension methods you will need to add the following to your module-level <code>build.gradle</code> 

<pre><code>repositories {
 google()
}

dependencies {
 implementation "androidx.core:core-ktx:1.2.0"
}
</code></pre>

See <a href="https://developer.android.com/kotlin/ktx" rel="noreferrer">here</a> for latest instructions for adding the dependency to your project.

Note that this will work for any subclass of <code>Drawable</code> and if the <code>Drawable</code> is a <code>BitmapDrawable</code> it will shortcut to use the underlying <code>Bitmap</code>.

If your <code>vector</code> image <code>intrinsicWidth</code> and <code>intrinsicHeight</code> is small and you try to display the bitmap to a big view, then you will see the result is blur.

In that case, you can provide a new width/height for your bitmap to get the better image (or you can increase the vector size in xml, but provide the <code>desireWidth</code> and <code>desireHeight</code> may be more flexible).

<pre><code>private fun getBitmap(drawableId: Int, desireWidth: Int? = null, desireHeight: Int? = null): Bitmap? {
 val drawable = AppCompatResources.getDrawable(context, drawableId) ?: return null
 val bitmap = Bitmap.createBitmap(
 desireWidth ?: drawable.intrinsicWidth,
 desireHeight ?: drawable.intrinsicHeight,
 Bitmap.Config.ARGB_8888
 )
 val canvas = Canvas(bitmap)
 drawable.setBounds(0, 0, canvas.width, canvas.height)
 drawable.draw(canvas)
 return bitmap
}

This gives you the bitmap in the size you want. In addition, it allows you to maintain or not transparency depending on each image for better performance with those that do not need it.
<pre><code>public static Bitmap drawableToBitmap(Resources res, int drawableId,
 int width, int height, boolean keepAlpha) {
 Drawable drawable = res.getDrawable(drawableId);
 Bitmap bmp = createBitmap(width, height, keepAlpha ?
 Bitmap.Config.ARGB_8888 : Bitmap.Config.RGB_565);
 Canvas cvs = new Canvas(bmp);
 drawable.setBounds(0, 0, width, height);
 drawable.draw(cvs);
 return bmp;
}
</code></pre>

For the vector drawable here given cup of code help us, but remember it might be null if drawable is not found of NULL
<pre><code>@Nullable
public static Bitmap drawableToBitmap(Context context, int drawableId) {
 Drawable drawable = ContextCompat.getDrawable(context, drawableId);
 if (drawable != null) {
 int width = drawable.getIntrinsicWidth();
 int height = drawable.getIntrinsicHeight();
 Bitmap bmp = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
 Canvas canvas = new Canvas(bmp);
 drawable.setBounds(0, 0, canvas.getWidth(), canvas.getHeight());
 drawable.draw(canvas);
 return bmp;
 }
 return null;
}
</code></pre>

In my application, I have to set a large icon for a notification.
LargeIcon must be a Bitmap, and my drawables are vector images (the new feature in Android, see <a href="http://developer.android.com/training/material/drawables.html#VectorDrawables">this link</a>)
The problem is when I try to decode a resource that is a vector image, I get a null returned.

Here is the sample of code :

<pre><code>if (BitmapFactory.decodeResource(arg0.getResources(), R.drawable.vector_menu_objectifs) == null)
 Log.d("ISNULL", "NULL");
 else
 Log.d("ISNULL", "NOT NULL");
</code></pre>

In this sample, when I replace R.drawable.vector_menu_objectifs with a "normal" image, a png for exemple, the result is not null (I get the correct bitmap)
Is there something I'm missing?

 在我的应用程序中，我必须为通知设置一个大图标。LargeIcon必须是位图，而我的绘图工具是矢量图像( Android中的新特性，请参阅 此链接 )问题是，当我尝试解码一个矢量图像的资源时，我得到一个null返回。 以下是代码示例： if (BitmapFactory.decodeResource(arg0.getR...
