Android项目实战之Glide 高斯模糊效果的实例代码
核心需要高斯模糊的库
compile'jp.wasabeef:glide-transformations:2.0.1'
针对于3.7的版本
使用方法为：
//加载背景， Glide.with(MusicPlayerActivity.this) .load(service.getImageUri()) .dontAnimate() .error(R.drawable.no_music_rotate_img) //设置高斯模糊,模糊程度(最大25)缩放比例 .bitmapTransform(newBlurTransformation(this,14,3)) .into(allBg);
针对4.+
Glide.with(context) .load(url) .apply(RequestOptions.bitmapTransform(newBlurTransformation(25,8))) .into(view);
BlurTransformation类源码：
importandroid.graphics.Bitmap;
importandroid.graphics.Canvas;
importandroid.graphics.Paint;
importandroid.support.annotation.NonNull;
importcom.bumptech.glide.load.engine.bitmap_recycle.BitmapPool;
importcom.bumptech.glide.load.resource.bitmap.BitmapTransformation;
importjava.security.MessageDigest;
importjp.wasabeef.glide.transformations.internal.FastBlur;
publicclassBlurTransformationextendsBitmapTransformation{
privatestaticfinalintVERSION=1;
privatestaticfinalStringID="BlurTransformation."+VERSION;
privatestaticintMAX_RADIUS=25;
privatestaticintDEFAULT_DOWN_SAMPLING=1;
privateintradius;
privateintsampling;
publicBlurTransformation(){
this(MAX_RADIUS,DEFAULT_DOWN_SAMPLING);
}
publicBlurTransformation(intradius){
this(radius,DEFAULT_DOWN_SAMPLING);
}
publicBlurTransformation(intradius,intsampling){
this.radius=radius;
this.sampling=sampling;
}
@Override
protectedBitmaptransform(@NonNullBitmapPoolpool,@NonNullBitmaptoTransform,intoutWidth,intoutHeight){
intwidth=toTransform.getWidth();
intheight=toTransform.getHeight();
intscaledWidth=width/sampling;
intscaledHeight=height/sampling;
Bitmapbitmap=pool.get(scaledWidth,scaledHeight,Bitmap.Config.ARGB_8888);
Canvascanvas=newCanvas(bitmap);
canvas.scale(1/(float)sampling,1/(float)sampling);
Paintpaint=newPaint();
paint.setFlags(Paint.FILTER_BITMAP_FLAG);
canvas.drawBitmap(toTransform,0,0,paint);
bitmap=FastBlur.blur(bitmap,radius,true);
returnbitmap;
}
@OverridepublicStringtoString(){
return"BlurTransformation(radius="+radius+",sampling="+sampling+")";
}
@Overridepublicbooleanequals(Objecto){
returnoinstanceofBlurTransformation&&
((BlurTransformation)o).radius==radius&&
((BlurTransformation)o).sampling==sampling;
}
@OverridepublicinthashCode(){
returnID.hashCode()+radius*1000+sampling*10;
}
@OverridepublicvoidupdateDiskCacheKey(@NonNullMessageDigestmessageDigest){
messageDigest.update((ID+radius+sampling).getBytes(CHARSET));
}
}
