Android development road-basic use of Glide image loading framework

1. Gilde loading animation (only fade in and fade out)

 Glide.with(mContext)
                .load(Uri.parse(rb.getThumb()))
                .transition(DrawableTransitionOptions.withCrossFade(100))//淡入淡出100m
                .into(holder.imageView);

2. There are two Bitmap methods for Gilde to obtain pictures:

①. 

 Glide.with(this)
                .asBitmap()
                .load(path)
                .signature(new ObjectKey(updateTime))
                .into(new SimpleTarget<Bitmap>() {
                    @Override
                    public void onResourceReady(@NonNull Bitmap resource, @Nullable Transition<? super Bitmap> transition) {
                        //这里的resource便是bitmap 
                        //要在with后面加入.asBitmap才可以获取到Bitmap
             
                    }
                });

②.

Glide.with(this)
                .asBitmap()
                .load(path)
                .listener(new RequestListener<Bitmap>() {
                    @Override
                    public boolean onLoadFailed(@Nullable GlideException e, Object model, Target<Bitmap> target, boolean isFirstResource) {
                        return false;
                    }

                    @Override
                    public boolean onResourceReady(Bitmap resource, Object model, Target<Bitmap> target, DataSource dataSource, boolean isFirstResource) {
                        //这是图片初始化准备的方法
                        //这里回调也是有Bitmap的
                        return false;
                    }
                })
                 .into(imageView);

3. Gilde prohibits the use of cache (I prefer to use it)

In some scenarios, Glide's cache reuse mechanism is not suitable, such as repeated operations on modified pictures, etc.

//取得时间 
 String updateTime= String.valueOf(System.currentTimeMillis());
//signature方法是前面key 已经单独接口ObjecyKey将时间传递
Glide.with(this)
                .asBitmap()
                .load(path)
                .signature(new ObjectKey(updateTime))    
                .init(imageView);
