    }
 
    String url = myUrls.get(position);
 
    Glide.with(myFragment)
        .load(url)
        .centerCrop()
        .placeholder(R.drawable.loading_spinner)

    1.三、Android-Universal-Image-Loader

    1.四、Fresco

        Fresco is a powerful system for displaying images in Android applications.
        Fresco takes care of image loading and display, so you don't have to. It will load images from the network, local storage, or local resources, and display a placeholder until the image has arrived. It has two levels of cache; one in memory and another in internal storage.
        In Android 4.x and lower, Fresco puts images in a special region of Android memory. This lets your application run faster - and suffer the dreaded OutOfMemoryError much less often.
    Fresco also supports:
        streaming of progressive JPEGs
        display of animated GIFs and WebPs
        extensive customization of image loading and display and much more!

        Android ButterKnife Zelezny 插件能夠有效的提升生產效率（Android Property Initializer）
        https://github.com/avast/android-butterknife-zelezny

     5.二、Parceler

        Parceler is a code generation library that generates the Android Parcelable boilerplate source code. No longer do you have to implement the Parcelable interface, the writeToParcel() or createFromParcel() or the public static final CREATOR. You simply annotate a POJO with @Parcel and Parceler does the rest. Because Parceler uses the Java JSR-269 Annotation Processor, there is no need to run a tool manually to generate the Parcelable code. Just annotate your Java Bean, compile and you are finished.
