Hello gyes
If you want to your imageview image blur then follow my blog sample..

main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background=“#e5e5e5”
    android:orientation="vertical">

 
                <ImageView
                    android:id="@+id/holder"
                    android:layout_width="match_parent"
                    android:layout_height="300dp"
                    android:scaleType="centerCrop"
                    android:src="@drawable/img_header"
                    android:tint="#11000000" />


</LinearLayout>


MainActivity.java

/*

*Samset created 17/02/2016
*/
public class MainActivity extends AppCompatActivity {
private ImageView placeholder;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    
 placeholder= (ImageView) findViewById(R.id.holder);
Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.img_header);
Bitmap blurredBitmap = blur(bitmap);
placeholder.setImageBitmap(blurredBitmap);


       
    }
//by samset
public Bitmap blur(Bitmap image) {
    if (null == image) return null;

    Bitmap outputBitmap = Bitmap.createBitmap(image);
    final RenderScript renderScript = RenderScript.create(this);
    Allocation tmpIn = Allocation.createFromBitmap(renderScript, image);
    Allocation tmpOut = Allocation.createFromBitmap(renderScript, outputBitmap);

   
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
        ScriptIntrinsicBlur theIntrinsic = ScriptIntrinsicBlur.create(renderScript, Element.U8_4(renderScript));
        theIntrinsic.setRadius(BLUR_RADIUS);
        theIntrinsic.setInput(tmpIn);
        theIntrinsic.forEach(tmpOut);
        tmpOut.copyTo(outputBitmap);
    }

    return outputBitmap;
}


}
