Question

I have an imageview and i set Image Resources programmatically like this:

int resourceId = getResources().getIdentifier(\"imagename\", \"drawable\", \"mypack         


        

Answer 1

Just simply use this library https://github.com/ChathuraHettiarachchi/BlurIM , I was having problem with BlurTransformation class had errors thats why couldn't use Glide transformation but this works fine.

BlurImage.withContext(this)
     .blurFromResource(R.drawable.YOUR_RESOURCE)
     .into(imageView);

Answer 2

You can use RenderScript to accomblish that as explained here or you can use the stackblur library to make a blurring effect in your image.

Usage of the stackblur library:

int resourceId = getResources().getIdentifier("imagename", "drawable", "mypackage");
// get bitmap from resource id
Bitmap bitmap = BitmapFactory.decodeResource(getResources(), resourceId);
StackBlurManager stackBlurManager = new StackBlurManager(bitmap);
// process the image using a certain radius
stackBlurManager.process(progress*4);
// obtain the image and load it into an ImageView or any other component
imgLock.setImageBitmap(stackBlurManager.returnBlurredImage());

Answer 3

There's the library that can use RenderScript so a blurring is blazingly fast and super easy to use:

<ru.egslava.blurredview.BlurredImageView
    ...
    android:src="@drawable/..."
    app:radius="0.3"
    app:keepOriginal="true"
    app:downSampling="2" />

Answer 4

You can use glide transformations https://github.com/wasabeef/glide-transformations you can blur the image with one line of code

Glide.with(this).load(R.drawable.demo)
    .bitmapTransform(new BlurTransformation(context))
    .into((ImageView) findViewById(R.id.image));
