This is simple method

set blur color with alpha

public class BlurImageView extends ImageView {
    Paint rectPaint;

  private  int blurcolor=Color.parseColor("#aeffffff");
    public BlurImageView(Context context) {
        this(context, null);

    }

    public BlurImageView(Context context, AttributeSet attrs) {
        this(context, attrs, 0);

    }

    public BlurImageView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);

        rectPaint=new Paint();
        rectPaint.setAntiAlias(true);
        rectPaint.setStyle(Paint.Style.FILL);
        rectPaint.setColor(blurcolor);
        invalidate();
    }

    public void setBlurcolor(int blurcolor) {
        this.blurcolor = blurcolor;
        invalidate();
    }

    @Override
    protected void onDraw(Canvas canvas) {
        super.onDraw(canvas);

        Log.i("BlurImageView","canvas");

        canvas.drawRect(getLeft(),0,getRight(),getHeight(),rectPaint);
    }
}
