Android中Glide加载库的图片缓存配置究极指南

Glide.with(context).load(...).asBitmap() //显示gif静态图片
Glide.with(context).load(...).asGif() //显示gif动态图片

 Glide.with(context).load(“视频路径“)

 //加载yourView1/10尺寸的缩略图，然后加载全图
Glide.with(yourFragment).load(yourUrl).thumbnail(0.1f).into(yourView)

 Glide.with(context)
  .load(“/user/profile/photo/path”)
  .asBitmap()
  .toBytes()
  .centerCrop()
  .into(new SimpleTarget<byte[]>(250, 250) {
    @Override
    public void onResourceReady(byte[] data, GlideAnimation anim) {
      // Post your bytes to a background thread and upload them here.
    }
  });

 (.animate(ViewPropertyAnimation.Animator))

 Glide.with(yourFragment)
  .load(yourFileDataModel)
  .signature(new StringSignature(yourVersionMetadata))
  .into(yourImageView);


 Glide.with(fragment)
  .load(mediaStoreUri)
  .signature(new MediaStoreSignature(mimeType, dateModified, orientation))
  .into(view);

 public class IntegerVersionSignature implements Key {
  private int currentVersion;
  public IntegerVersionSignature(int currentVersion) {

  }
  @Override
  public boolean equals(Object o) {
    if (o instanceof IntegerVersionSignature) {

      return currentVersion = other.currentVersion;
    }
    return false;
  }
  @Override

    return currentVersion;

  @Override

 Glide.with(yourFragment)
  .using(new MyUrlLoader())

ModelLoaderFactory然后使用Glide将它注册到GlideModule当中

 public class MyGlideModule implements GlideModule {
  ...
  @Override
  public void registerComponents(Context context, Glide glide) {
    glide.register(MyDataModel.class, InputStream.class, 
      new MyUrlLoader.Factory());

}

 Glide.with(yourFragment)
  .load(yourModel)
  .into(yourView);
