Making Image Blur in Android

Hello Every One, to make Image Blur in Android I Used a Simple Approach By Using Glide

https://github.com/bumptech/glide

Follow Following Steps to Achieve that
 Step 1:
Create a XML File

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:app="http://schemas.android.com/apk/res-auto"    xmlns:tools="http://schemas.android.com/tools"    android:id="@+id/main_parent_layout"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical">

        <ImageView            android:id="@+id/user_image_transparent"            android:layout_width="match_parent"            android:layout_height="match_parent"            android:alpha="1"            android:adjustViewBounds="true"            android:scaleType="centerCrop"            android:background="@drawable/splash_bg"/>    

</LinearLayout>

 Step 2:
In your Main Activity use this Method To make Image Blur

DrawableRequestBuilder drawableRequestBuilder = Glide.with("Pass your App Context Here")
        .load(image_url)
        .bitmapTransform(new BlurTransformation(mContext))
        .animate(android.R.anim.fade_in)//If You Want To Animate
        .placeholder(R.drawable.ic_loading)
        .error(R.drawable.ic_no_image);
drawableRequestBuilder.into(imageView);

Step 3:

Create Class BlurTransformation:

import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.Canvas;
import android.graphics.Paint;
import android.os.Build;
import android.renderscript.RSRuntimeException;

import com.bumptech.glide.Glide;
import com.bumptech.glide.load.Transformation;
import com.bumptech.glide.load.engine.Resource;
import com.bumptech.glide.load.engine.bitmap_recycle.BitmapPool;
import com.bumptech.glide.load.resource.bitmap.BitmapResource;

public class BlurTransformation implements Transformation<Bitmap> {

    private static int MAX_RADIUS = 25;
    private static int DEFAULT_DOWN_SAMPLING = 1;

    private Context mContext;
    private BitmapPool mBitmapPool;

    private int mRadius;
    private int mSampling;

    public BlurTransformation(Context context) {
        this(context, Glide.get(context).getBitmapPool(), MAX_RADIUS, DEFAULT_DOWN_SAMPLING);
    }

    public BlurTransformation(Context context, BitmapPool pool) {
        this(context, pool, MAX_RADIUS, DEFAULT_DOWN_SAMPLING);
    }

    public BlurTransformation(Context context, BitmapPool pool, int radius) {
        this(context, pool, radius, DEFAULT_DOWN_SAMPLING);
    }

    public BlurTransformation(Context context, int radius) {
        this(context, Glide.get(context).getBitmapPool(), radius, DEFAULT_DOWN_SAMPLING);
    }

    public BlurTransformation(Context context, int radius, int sampling) {
        this(context, Glide.get(context).getBitmapPool(), radius, sampling);
    }

    public BlurTransformation(Context context, BitmapPool pool, int radius, int sampling) {
        mContext = context.getApplicationContext();
        mBitmapPool = pool;
        mRadius = radius;
        mSampling = sampling;
    }

    @Override    public Resource<Bitmap> transform(Resource<Bitmap> resource, int outWidth, int outHeight) {
        Bitmap source = resource.get();

        int width = source.getWidth();
        int height = source.getHeight();
        int scaledWidth = width / mSampling;
        int scaledHeight = height / mSampling;

        Bitmap bitmap = mBitmapPool.get(scaledWidth, scaledHeight, Bitmap.Config.ARGB_8888);
        if (bitmap == null) {
            bitmap = Bitmap.createBitmap(scaledWidth, scaledHeight, Bitmap.Config.ARGB_8888);
        }

        Canvas canvas = new Canvas(bitmap);
        canvas.scale(1 / (float) mSampling, 1 / (float) mSampling);
        Paint paint = new Paint();
        paint.setFlags(Paint.FILTER_BITMAP_FLAG);
        canvas.drawBitmap(source, 0, 0, paint);

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR2) {
            try {
                bitmap = RSBlur.blur(mContext, bitmap, mRadius);
            } catch (RSRuntimeException e) {
                bitmap = FastBlur.blur(bitmap, mRadius, true);
            }
        } else {
            bitmap = FastBlur.blur(bitmap, mRadius, true);
        }

        return BitmapResource.obtain(bitmap, mBitmapPool);
    }

    @Override public String getId() {
        return "BlurTransformation(radius=" + mRadius + ", sampling=" + mSampling + ")";
    }
}

Paste that Code in it



Do not Forget To Add Internet Permission if you are Using and Image URL



Work for Both Local and Remote Image
