Example 22 with Request

use of com.bumptech.glide.request.Request in project glide by bumptech.

the class ViewTarget method getRequest.

/**
   * Returns any stored request using {@link android.view.View#getTag()}.
   *
   * <p> For Glide to function correctly, Glide must be the only thing that calls {@link
   * View#setTag(Object)}. If the tag is cleared or put to another object type, Glide will not be
   * able to retrieve and cancel previous loads which will not only prevent Glide from reusing
   * resource, but will also result in incorrect images being loaded and lots of flashing of images
   * in lists. As a result, this will throw an {@link java.lang.IllegalArgumentException} if {@link
   * android.view.View#getTag()}} returns a non null object that is not an {@link
   * com.bumptech.glide.request.Request}. </p>
