Android关于Glide的使用(高斯模糊、加载监听、圆角图片)

Glide.with(context)
 .load(url)
 .placeholder(R.drawable.loading) //占位符 也就是加载中的图片，可放个gif
 .error(R.drawable.failed) //失败图片
 .into(view);

Glide.with(context)
.load(url)
.asGif() // 只能加载gif文件
.into(imageView); 

Glide.with(context)
 .load(url)
 .placeholder(R.drawable.loading)
 .error(R.drawable.failed) 
 .crossFade(1000) // 可设置时长，默认“300ms”
 .into(view);

Glide.with(context)
 .load(url)
 .placeholder(R.drawable.loading)
 .error(R.drawable.failed) 
 .crossFade(1000)
 .bitmapTransform(new BlurTransformation(context,23,4)) // “23”：设置模糊度(在0.0到25.0之间)，默认”25";"4":图片缩放比例,默认“1”。
 .into(view);

Glide.with(this).load(internetUrl).listener(new RequestListener() {
   @Override
   public boolean onException(Exception e, String model, Target target, boolean isFirstResource) {
    Toast.makeText(getApplicationContext(),"资源加载异常",Toast.LENGTH_SHORT).show();
    return false;
   }
   //这个用于监听图片是否加载完成
   @Override
   public boolean onResourceReady(GlideDrawable resource, String model, Target target, boolean isFromMemoryCache, boolean isFirstResource) {
    Toast.makeText(getApplicationContext(),"图片加载完成",Toast.LENGTH_SHORT).show();
    return false;
   }
  }).into(imageView);

Glide.with( context )
 .load( eatFoodyImages[0] )
 .skipMemoryCache( true )
 .into( imageViewInternet );

Glide.with( context )
 .load( eatFoodyImages[0] )
 .diskCacheStrategy( DiskCacheStrategy.NONE )
 .into( imageViewInternet );

public class GlideCircleTransform extends BitmapTransformation {
 public GlideCircleTransform(Context context) {
  super(context);
 }

 @Override
 protected Bitmap transform(BitmapPool pool, Bitmap toTransform, int outWidth, int outHeight) {
  return circleCrop(pool, toTransform);
 }

 private static Bitmap circleCrop(BitmapPool pool, Bitmap source) {
  if (source == null) return null;
  int size = Math.min(source.getWidth(), source.getHeight());
  int x = (source.getWidth() - size) / 2;
  int y = (source.getHeight() - size) / 2;
  // TODO this could be acquired from the pool too
  Bitmap squared = Bitmap.createBitmap(source, x, y, size, size);
  Bitmap result = pool.get(size, size, Bitmap.Config.ARGB_8888);
  if (result == null) {
   result = Bitmap.createBitmap(size, size, Bitmap.Config.ARGB_8888);
  }
  Canvas canvas = new Canvas(result);
  Paint paint = new Paint();
  paint.setShader(new BitmapShader(squared, BitmapShader.TileMode.CLAMP, BitmapShader.TileMode.CLAMP));
  paint.setAntiAlias(true);
  float r = size / 2f;
  canvas.drawCircle(r, r, r, paint);
  return result;
 }

 @Override
 public String getId() {
  return getClass().getName();
 }
}

Glide.with(mContext)
 .load(imageUrl)
 .transform(new GlideCircleTransform(mContext))
 .into(holder.imageView);
