The easiest way to do that is use a library. Take a look at this one: <a href="https://github.com/wasabeef/Blurry" rel="noreferrer">https://github.com/wasabeef/Blurry</a>

With the library you only need to do this:

<pre><code>Blurry.with(context)
 .radius(10)
 .sampling(8)
 .color(Color.argb(66, 255, 255, 0))
 .async()
 .onto(rootView);
</code></pre>

You can have a view with Background color as black and set alpha for the view as 0.7 or whatever as per your requirement.

this might not be the most efficient solution but I had to use it since the wasabeef/Blurry library didn't work for me. this could be handy if you intend to have some getting-blurry animation:

1- you need to have 2 versions of the picture, normal one and the blurry one u make with photoshop or whatever

2- set the images fit on each other in your xml, then one of them could be seen and that's the upper one

3- set fadeout animation on the upper one:

<pre><code>final Animation fadeOut = new AlphaAnimation(1, 0);
 fadeOut.setInterpolator(new AccelerateInterpolator());
 fadeOut.setDuration(1000);


 fadeOut.setAnimationListener(new Animation.AnimationListener() {
 @Override
 public void onAnimationStart(Animation animation) {}

 @Override
 public void onAnimationEnd(Animation animation) {upperone.setVisibility(View.GONE);}

 @Override
 public void onAnimationRepeat(Animation animation) {}
 });

 upperone.startAnimation(fadeOut);

}|4482010|2.使用Glide将图像设置为ImageView。|4482011|例如：|4482012|Glide.with(this)
+++++.load(expertViewDetailsModel.expert.image)
+++++.asBitmap()
+++++.transform(new+BlurTransformation(this))
+++++.into(ivBackground);|4482013|entityMap^0|0|0|0|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Y|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|Z|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|10|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|11|8|@]|9|@]|A|$]]|$1|K|3|L|5|6|7|12|8|@]|9|@]|A|$]]|$1|M|3|N|5|6|7|13|8|@]|9|@]|A|$]]|$1|O|3|P|5|F|7|14|8|@]|9|@]|A|$G|H]]|$1|Q|3|R|5|6|7|15|8|@]|9|@]|A|$]]|$1|S|3|T|5|6|7|16|8|@]|9|@]|A|$]]|$1|U|3|V|5|F|7|17|8|@]|9|@]|A|$G|H]]|$1|W|3|-4|5|6|7|18|8|@]|9|@]|A|$]]]|X|$]]

The simplest way to achieve this is given below,

I)

<pre><code>Glide.with(context.getApplicationContext())
 .load(Your Path) 
 .override(15, 15) // (change according to your wish)
 .error(R.drawable.placeholder)
 .into(image.score);
</code></pre>

else you can follow the code below..

II)

1.Create a class.(Code is given below)

<pre><code>public class BlurTransformation extends BitmapTransformation {

 private RenderScript rs;

 public BlurTransformation(Context context) {
 super( context );

 rs = RenderScript.create( context );
 }

 @Override
 protected Bitmap transform(BitmapPool pool, Bitmap toTransform, int outWidth, int outHeight) {
 Bitmap blurredBitmap = toTransform.copy( Bitmap.Config.ARGB_8888, true );

 // Allocate memory for Renderscript to work with
 Allocation input = Allocation.createFromBitmap(
 rs, 
 blurredBitmap, 
 Allocation.MipmapControl.MIPMAP_FULL, 
 Allocation.USAGE_SHARED
 );
 Allocation output = Allocation.createTyped(rs, input.getType());

 // Load up an instance of the specific script that we want to use.
 ScriptIntrinsicBlur script = ScriptIntrinsicBlur.create(rs, Element.U8_4(rs));
 script.setInput(input);

 // Set the blur radius
 script.setRadius(10);

 // Start the ScriptIntrinisicBlur
 script.forEach(output);

 // Copy the output to the blurred bitmap
 output.copyTo(blurredBitmap);

 toTransform.recycle();

 return blurredBitmap;
 }

 @Override
 public String getId() {
 return "blur";
 }
}
</code></pre>

2.Set image to ImageView using Glide.

eg:

<pre><code>Glide.with(this)
 .load(expertViewDetailsModel.expert.image)
 .asBitmap()
 .transform(new BlurTransformation(this))
 .into(ivBackground);
</code></pre>

blocks|key|4481128|text|您可以使用：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4481129|Glide.with(getContext()).load(R.mipmap.bg)
+++++.apply(bitmapTransform(new+BlurTransformation(22)))
+++++.into((ImageView)+view.findViewById(R.id.imBg));|code-block|syntax|javascript|4481130|这需要在build.gradle文件中添加以下内容：|offset|length|style|CODE|4481131|implementation+'jp.wasabeef:glide-transformations:4.0.0'|4481132|entityMap^0|0|0|4|C|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|S|8|@$I|T|J|U|K|L]]|9|@]|A|$]]|$1|M|3|N|5|D|7|V|8|@]|9|@]|A|$E|F]]|$1|O|3|-4|5|6|7|W|8|@]|9|@]|A|$]]]|P|$]]

You can use:
<pre class="lang-java prettyprint-override"><code>Glide.with(getContext()).load(R.mipmap.bg)
 .apply(bitmapTransform(new BlurTransformation(22)))
 .into((ImageView) view.findViewById(R.id.imBg));
</code></pre>
This requires the following addition to your <code>build.gradle</code> file:
<pre><code>implementation 'jp.wasabeef:glide-transformations:4.0.0'
</code></pre>

you can use Glide for load and transform into blur image,
1) for only one view, 

<pre><code>val requestOptions = RequestOptions()
 requestOptions.transform(BlurTransformation(50)) // 0-100
Glide.with(applicationContext).setDefaultRequestOptions(requestOptions)
 .load(imageUrl).into(view)
</code></pre>

2) if you are using the adapter to load an image in the item, you should write your code in the if-else block, otherwise, it will make all your images blurry. 

<pre><code> if(isBlure){
 val requestOptions = RequestOptions()
 requestOptions.transform(BlurTransformation(50))
 Glide.with(applicationContext).setDefaultRequestOptions(requestOptions)
 .load(imageUrl).into(view )
}else{
 val requestOptions = RequestOptions()
 Glide.with(applicationContext).setDefaultRequestOptions(requestOptions).load(imageUrl).into(view)
}

如下图所示，模糊背景图像的最佳方法是什么？我看到了一些代码和库，但它们已经有几年的历史了，或者像BlurBehind库一样，但它不会产生同样的效果。提前感谢！​​
